Choosing Between Different Modes of Transport When Traveling

Each mode of transport whether it be by land, air, or sea comes with its own set of advantages and disadvantages, and what works for one traveler may be a different story for another.

When deciding on which modes of transport will work for you, you must consider factors like the length of your trip, your desired comfort level, size of traveling group, mobility issues, amount of luggage, budget, and of course phobias.

So without further ado, let’s get a move on to comparing the various transport options you are most likely to have while traveling.

It may not be the quickest way to travel, but you definitely can’t beat the price. The best thing about walking to places is that there are no tickets to purchase and no timetables to adhere to. You can walk anywhere , at any time of day or night.

Many cities are pedestrian-friendly, and so long as you set yourself up in accommodation near the city center, you can usually reach most nearby top attractions quite comfortably. Most popular cities of course also offer up organized walking tours which are free.

Walking allows you to really get a feel for a destination and allows you to discover hidden gems you might otherwise miss on faster transport. Many people book trips that solely focus on walking, such as when embarking on famous multi-day treks like the Inca Trail or Camino de Santiago .

One of the most eco-friendly ways to travel on wheels is via bicycle. It’s also quite economical since bike rentals are far cheaper than car rentals and there are no additional fuel expenses. Additionally, in many cities it is actually quicker and easier to ride bicycles places than to drive.

You can simply rent a city bike to get to restaurants and attractions quicker than walking or can make biking a bigger part of your vacation such as when bikepacking or cycle touring . The great thing about biking is that it’s suitable for most ages so long as you’re relatively fit, and you can easily ride with small children and even pets in tow.

Many tour companies offer organized cycling tours in various destinations, some focusing on smooth paved roads while others are more rugged and remote off-roading rides. For trips where you will strictly focus on biking for your main transport, you are wise to travel light and maybe purchase some quality rack-mounted bicycle pannier bags or more modern bikepacking bags .

It’s safe to say most travelers rely on vehicles for at least a portion of every trip. Whether you’re hailing a cab, scheduling an Uber, or renting your own vehicle, this has become the most widely used mode of transportation for travelers worldwide.

There are a few cons of hiring a vehicle such as it being expensive, especially when you consider the added insurance, fuel, and parking costs. You may have to quickly get used to driving on the opposite side of the road and decipher road signs written in another language and you may need to book a rental far in advance for popular destinations during peak season.

Renting a vehicle is, however, one of the most comfortable ways to travel in terms of privacy and allowing you the freedom to travel at your own pace without restrictive timetables. There’s no rubbing shoulders with strangers and it’s much easier to carry shopping back to your hotel.

Of course having someone else do the driving for you such as a taxi or Uber may be best option when you don’t really know a city well or feel the driving conditions may be too stressful or dangerous. This option may be more economical as well if you don’t plan on driving places very often or very far distances, and you of course don’t need to worry about having one too many drinks at the bar.

There’s also the option of renting an RV such as a motorhome or campervan which will allow you to easily travel further afield while avoiding expensive hotel costs since your vehicle doubles as your accommodation. You also may benefit from having onboard bathrooms and cooking facilities which can help you save on meal costs while traveling.

Yes they may have tight security regulations, long waiting times, baggage restrictions, and a number of other inconveniences, but air travel still reigns supreme over car, train and bus travel in most cases.

Let’s face it, when most of us think of travel we envision flights and searching online for the cheapest airfares . Flying is by far the quickest and most practical way to travel in most cases. It’s often the only real way to reach international destinations without having to endure lengthy travel times on trains or ships.

Flying may be one of the most expensive ways to travel, but in many cases it’s actually not that bad and if you consider your time as money than it’s probably actually the cheapest way to travel. Comfort is usually pretty good on most airlines, and Business/First-Class seats and service can be downright amazing.

Plane travel is also extremely safe, with crashes and other accidents being extremely rare thanks to meticulous checks before flights. You are far more likely to get injured or die on the roadways .

Air travel also allows you to be productive while traveling as you can easily whip out your laptop and possibly even take advantage of in-flight WiFi. Most planes traveling internationally are also equipped with in-flight entertainment systems which offer up loads of movies, TV series, music, and games.

And as hectic as airports and getting to your gate can be, there are some truly beautiful airports that have become attractions in and of themselves such as Singapore’s Changi Airport . This only helps to enhance the air travel experience for many travelers.

Helicopters

A more exciting air travel option is booking a helicopter flight. A helicopter is a great way to explore a city’s sights from above for a unique perspective. You’ll find many popular travel destinations offer quick helicopter tours that can easily be squeezed into your itinerary.

Helicopter charters may also be an option when it comes to travel and it may be less expensive than you may think. Not only has helicopter travel become more affordable, they also can land almost anywhere . This allows you to visit unique destinations not accessible by planes or close to airports.

Being able to access hard-to-reach areas means getting to experience places not affected by mass tourism. You’ll also find the check-in process and security checks are much quicker than booking a normal plane flight.

Booking a helicopter flight is a great option for when you want to mark a special occasion such as a birthday, anniversary, honeymoon, or marriage proposal. They can also be beneficial in terms of needing a medical charter .

Motorcycles

Who doesn’t dream of riding a motorcycle at least once? Traveling is a great excuse to tick riding a motorcycle off your bucket list and what better way to do it than rent a Harley .

In order to rent a motorcycle legally abroad, you’ll likely need an unrestricted motorcycle endorsement added to your driver’s license and possibly an international driving permit. Depending on where you travel, you may also need a motorcycle license to ride a scooter/moped or may be restricted to an engine size of 50cc or less with a normal license.

Remember that just because a company may be willing to rent you a bike or scooter without a proper license doesn’t make it legal and you could end up facing fines if caught and you won’t be covered by your travel insurance in the event of an accident or injury.

Always make sure to wear a helmet and proper protective clothing. You should also be an experienced motorcycle rider when riding overseas. Driving laws in some countries may not be as strict or adhered to and this can lead to more dangerous conditions than you are used to back home.

Traveling by motorcycle can come with a number of benefits including being more fuel efficient than a vehicle, getting discounts on certain motorways, and possibly finding easier parking. You may want to consider shipping your own bike overseas when planning a long journey across multiple countries as it can sometimes be difficult finding bikes with engines larger than a 125cc .

Buses are one of the most cost-effective ways to travel, but you’ll likely end up paying for it dearly when it comes to forgoing comfort. While there are nice buses out there, there are far more that are pretty dull or downright depressing in some locations.

They can often be jam-packed and may be lacking air conditioning and bathrooms, even on long haul routes. Short bus journeys around town on public buses may be bearable and hop-on-hop-off buses can be fun at times, but overnight sleeper buses can sometimes be brutal despite being able to recline and saving on paying for a night’s accommodation.

Whereas some destinations may still require you to carry change around for the bus, many countries are now accepting contactless payments via credit cards and apps. Some are now also equipped with WiFi.

Trains are a great way to experience places which many people don’t get to see or may be too dangerous or grueling to drive through such as The Ghan through Australia’s hot and arid Outback, VIA Rail’s journey across the rugged Canadian wilderness from Vancouver to Montreal, or the Trans-Siberian Railway .

Aside from plane travel, trains are also usually the next fastest way to travel thanks to not having to wait in traffic or being held up by road construction. However, train routes often do cover quite a lot of ground with few stops so it may not be great if you don’t like being cooped up for long periods.

Of course train travel comforts and overall experiences can vary greatly depending on where you’re traveling and which class ticket you have. You may be rewarded with exceptional scenery from a luxurious rail carriage complete with fine dining, or may be stuck sleeping on an uncomfortable seat that doesn’t recline eating a bag of chips you packed yourself.

Train trips can be everything from a few hours to journeys that last several days, some being simply a way of getting from point A to Point B while others are carefully planned travel experiences with unique off-train experiences included with the trip.

One bonus with train travel is that most have bathrooms onboard which is great if you happen to have IBS or other issue which requires you to have easy access to a loo. And some newer trains offer free WiFi like buses.

You don’t necessarily need to book a cruise to incorporate boating into your travel plans. Many cities have boating as part of their public transportation such as ferries and water taxis. There are also many island destinations that are only serviced by ferries, as well as popular attractions around the world that are only accessible by boat like Alcatraz or the Statue of Liberty .

Getting out on the water will allow you to get a unique view of a city and you can often even travel between two different countries in a short amount of time. The vessel itself can be an adventure, with seemingly endless boating adventures available such as tall ship cruises through the Caribbean, junk boats in Southeast Asia, Venice gondolas, or a catamaran in the Great Barrier Reef.

There are then cruises which allow you to basically come aboard and then leave all the travel planning to the crew. You get to travel with your accommodation, entertainment is free, shopping is available, and you may not have to pay for any meals.

There are plenty of cruise options to suit different travelers whether you’re after a luxury experience on a mega cruise ship or an adventure cruise on a smaller ship with few passengers such as those visiting the Arctic and Antarctic .

A few drawbacks of sea or river travel to be aware of include seasickness, overcrowding in some cases when speaking of ferries, potential sickness outbreaks which can confine you to your cabin, and missing out on ports of call due to bad weather.

Mass Rapid Transit

One sure way to reduce your carbon footprint while traveling is to use mass rapid transit. Most popular big cities offer some sort of metro, subway, tube, or underground and this is probably the safest mode of ground transport while traveling.

Mass rapid transport is also usually quite economical, surprisingly clean, and fairly easy to locate stops and find where you need to go. It’s also extremely punctual and therefore reliable in terms of getting where you need to go when you need to get there.

Cities like London, Paris, Tokyo, Singapore, and New York all have extensive rapid transit systems in place that will allow you to quickly and easily make your way to many of the top attractions, restaurants, and hotels.

The one big drawback of rapid transit is that it’s definitely not quiet or private. You can expect it to be usually crowded and often a bit hectic.

These may be the most readily available ways to get around while traveling, but there are many more ways to explore this world. Some more unusual ways to travel include bamboo trains, horseback riding, dog sledding, ziplining, suspension railways, hydrofoils, paragliding , tuk-tuks, funiculars, or a hot air balloon .

Travel Booking Group Airfare – Consider Your Options

How group travel organizers can turn the airlines win/lose into a win-win!

When booking group airfare, travel planners are presented with new options

Have you noticed nothing’s easy anymore? I have…especially when it comes making group airline reservations. But when I complain to my wife (who is also my business partner) about it, she just tells me that I’m turning into my father and to “get over it.” So I walk away mumbling to myself, thinking about what a pleasure it used to be doing business with the airlines. In the “good ol’ days” making group reservations was a piece of cake. Today however, it can be a real headache and occasionally even a migraine when booking group airfare. Let’s consider our options so we can make a smart choice.

Getting your group to their vacation destination

OK, you have your group of let’s say 30 people. You have picked the perfect vacation destination for your group and you have the perfect itinerary. Now all you have to do is to get them there. Many times group-wise, this can be a challenge. Let me rephrase that; Most of the time this will be a challenge. However, do not fear for there is a solution, and a great one at that!

The “Good Ol’ Days” of Booking Group Airfares

First, let me give you some insight into how the leisure group travel business used to operate in the “good ol’ days’ (the 1970’s and early 1980’s). Back then the idea of group travel was to book your group from Point A to Point B and everyone would travel together. Everyone travels in a group right? The whole group would depart from, and return to one city such as Atlanta, Kansas City, Phoenix, Los Angeles, etc. The departure city was known as the “Gateway” city. There are three reasons the group travel organizer (GTO) operated that way:

Back then , most groups were developed locally through their churches, social organizations, friends and family, etc. and most of the tour participants knew one another.
Back then , a GTO would call several airlines and get a competitive rate for their group. And when I say “call” I mean that literally; no Internet, no websites, no online bookings. You actually spoke with a real “live” person! I’m not making this up…it’s true.
Back then , most GTOs were usually travel agents. They would develop their groups, book the group air with their chosen airline and then hand write the airline tickets (again…not kidding). For their efforts, they received a commission from the airline. Everyone was happy! Then along came the deregulation of the airline industry, which was the beginning of the end of the “good ol’ days.”

Airlines are partners in travel no more…

Fast forward to today. Because of the deregulation over the years, airlines have cut the commissions that they used to pay to the agencies. In addition, most of the airlines got rid of their sales representatives and moved all of their departments into a central booking location or home-based satellite offices, thus ending a beautiful era of personal service built on solid business relationships. Why have I told you all of this? Because I want you to understand that the concept of group travel, as it used to be, is dead and gone.

The Internet dilemma

As the current situation stands now with the airlines, it’s sort of “them against us.” Depressed? Don’t be…I have a great solution to this dilemma!

The airline situation has been a dilemma for me also. Besides our incentive travel and conference and meeting planning company, ETC Services, Inc., my wife Anne and I also have our own personal travel club, Friends of Carl and Anne . Trying to get good air rates for my small groups is an absolute headache. Why? Because of the Internet! All of the airlines now have great websites which any individual can access and get a plethora of “super deals.” Besides the airlines themselves, the public has access to numerous travel websites such as Travelocity.com, Priceline.com, to mention a few, which offer additional options for discount airline travel, hotel accommodations, car rentals, etc. Even Wal-Mart’s Sam’s Club has an online travel agency as well as retail agencies in many of their stores. The end result – all of this online competition lowers the price of airline tickets for individuals. Not bad for the individuals, a headache for the GTO.

All of the factors I’ve mentioned exacerbate the problem of trying to get a decent group airfare from the airlines. Individuals, many times, can actually buy a ticket cheaper than the group airfares I negotiate with the airlines, which makes me (you) look bad. What to do?

What is the solution for booking group airfares?

Here is the solution to solving the group travel airfares situation; Have your group participants make their own airline reservations! I know that this may seem like you are not doing your job as a GTO but trust me, you will be doing your participants a favor while taking a load off of your shoulders at the same time. This is how I operate my Friends of Carl and Anne groups and believe me, it is a win-win proposition for everyone.

The following is the explanation that I have on our website of why I suggest that my Friends of Carl and Anne participants make their own airline reservations:

AIRLINE RESERVATION INFORMATION

WHY? – Some of you may be wondering why the air transportation is not included in our tour. Here are a few reasons why it is to your advantage to book your own airline reservations…

First of all there are very few “deals” to be had for booking a group with the airlines today (any airlines). Even if I could get a decent airfare, I would still be forced to “gateway” the group out of one particular city. This means that you would be forced to travel from your home city to one of the gateway city airports to rendezvous with the group for the international portion of your flight. Bummer.
There is no “rhyme or reason” to how airlines price their tickets today. You as individuals, most of the time, can actually get a better airfare than someone (like me) who has a group. Go figure!

Here are the advantages of making your own airline reservations:

You can choose which airline you want to use (not forced to fly on a particular airline or fly out of a particular city that may actually be inconvenient for you)
You can choose a schedule that fits your travel plans
You can use Frequent Flyer points to purchase your tickets
You can alter your itinerary to go a few days earlier or stay a few days later
You can fly economy class or first/business class if you want, it’s up to you
If you are traveling with a few of your friends, it’s easier to coordinate your schedules and seating assignments

When it comes to making your own reservations, I suggest booking with one of the online travel companies, like www.travelocity.com, www.Expedia.com, or www.ORBITZ.com. All-in-all, there are definite advantages to booking your own flights. BUT, if you would like some assistance or advice, or would like for us to schedule your air for you, just let us know and we will be happy to help you.

Which online travel company do I use?

I usually use Frequent Flyer points to purchase our tickets. When we choose not to use our Frequent Flyer points, I usually start with Travelocity (www.travelocity.com). The deals vary from day-to-day and company to company so it doesn’t hurt to shop and compare .

That’s my solution for air reservations

Making your own airline reservations is now the standard operating procedure for my group participants and they all love it. It’s on a rare occasion that someone asks us to make their reservation for them, but when they do, no problem. We just get online and book the reservation or go to a local agency and have them do the ticketing for us. Simple.

Here is something else that you should know. This solution saves you more than just the hassle of booking your group with the airlines, it also saves you from having to pay an immediate deposit of $100 per person (deposits vary from airline to airline but $100 pp is pretty standard) to block the group space.

Think about this; If you have six groups in various stages of operation at an average of 30 pax per group, you could potentially have $18,000 of your hard earned money sitting in some airline’s bank account until your groups depart for their trip. You may have that kind of money laying around, but I don’t!

So, here’s the win-win for you:

Win #1 – Your trip participants make their own airline reservations. They book exactly the schedule they want and send you the reservation info. They’re happy, you’re happy.

Win #2 – You don’t have to pay out any money for deposits, allowing you to keep your money in your bank and additionally, saving you all of the hassle of signing contracts, meeting payment deadlines, dealing with schedule/name changes (your participants do that), etc. Life is good!

Last Point: Meeting & Greeting your group at the destination

Since your group participants are making their own airline reservations and will be arriving individually and not as a group, the standard “meet the whole group upon arrival at the airport” is no longer feasible.

Basically you have two options on how to handle your meet and greet:

If you personally want to meet your group participants on the ‘official” arrival day (Remember, some of the participants may arrive a few days earlier than the majority of the group), either:

Meet them upon their individual arrivals at the airport (I highly suggest this option if possible)
Meet them upon their arrival at the hotel

Regarding Option #1 – I know that meeting your people at the airport on the official arrival date sounds like a long day at the airport but it’s usually not, for this reason; Most airlines will have flights arriving at close proximity to each other at major destinations, so most of your group will probably arrive on two or three incoming flights, usually within a few hours of each other. Using my Friends of Carl and Anne group to Paris last year as an example, my whole group (whose maximum size I keep to 30 pax), all arrived on three separate flights within three hours and fifteen minutes. The actual time would have been less had there not been a forty-five minute delay with one of the flights.

Also, during the waiting time between flight arrivals , this is a great opportunity for you to spend some time with your local DMC representative (who will be at the airport with you greeting your people) going over your program, clarifying any last minute changes and just getting to know them a little better in general. Remember, a solid way to build your travel business is establishing strong personal relationships with your travel industry partners…this means everyone from the CEO down to hospitality desk hosts. They are all important to the ultimate success of your travel programs and ultimately, your travel business.

Option #2 is a little easier but not quite as personal, in my opinion, as meeting your people as they come out of customs at the airport. When your people exit customs and immediately see a friendly face, they know that you are there for them and that they are in good hands.

However, meeting your people as they arrive at the hotel is still a nice touch and very much appreciated by your participants. Since you have the flight arrival times of your people, you can estimate their time of arrival at the hotel and can be waiting for them in the lobby to greet them.

Either option you choose is a winner and fulfills that personal, hands-on service that every tour program should have.

To sum it all up, I guess I have finally realized that the Internet is really my friend and not my enemy because it sure saves me a lot of time and outlay of my money to have my group members make their own reservations. Try my solution with your next group. I’m sure that you will be happy with the end result!

Engineers adapt their fundamental science and math skills to different situations. Understanding the science of natural phenomena enables engineers to design and build appropriate structures and systems. By combining their expertise in inventing measurement and data gathering tools with their ability to analyze and learn from past failures, engineers continually improve designs and systems for the benefit of people. This process of gathering and analyzing data to better understand problems and formulate solutions is used in all engineering disciplines.

After this activity, students should be able to:

Understand fundamental differences between navigation on land, water, air and in space.
Identify major features and read the fundamental symbols and information provided on land maps, nautical charts and aeronautical charts.
Explain the concept of dead reckoning (relationship between speed, time, distance and direction) as it applies to navigation estimation.
Understand beacon nomenclature, symbols and information as found on nautical charts.

With the students, brainstorm the differences between traveling in an airplane and traveling on foot. (Possible answers: You are up in the air, you are going faster.) Do the students think that using a standard city street map would help them navigate from an airplane? (Possible answer: No, because you would pass over a city in a couple minutes.) What kind of map would be useful for flying an airplane? (Possible answer: One that covers a much larger area.) Maps for pilots are called aeronautical charts, and we will take a look at them today.

Pose the same questions for traveling by sea. Does a city street map help you travel in a sailboat? (Possible answer: No, because there are no street signs on the ocean.) Street maps help you navigate by showing landmarks like street names, but there are no street signs on the ocean! What kinds of landmarks may be found when traveling on the sea? (Possible answers: Lighthouses, beacons, islands, buoys.) During the past few millennia, many nations and peoples have created landmarks that are either on land and visible from sea or floating in the water, like buoys. Lighthouses are a great example of landmarks for sailors. They are like street signs for the ocean. They have a big, bright light so sailors can easily see them day or night, in good weather or in storms. Seeing lighthouses helps sailors avoid hitting land or crashing into rocks. Nautical charts allow sailors to determine exactly where they are on a large body of water. Students can learn the major features of nautical charts by looking at a real charts and drawing their own in the associated activity Nautical Navigation .

What about traveling in space? How do astronauts have any idea about where they are? There certainly are no street signs in space. People on Earth can locate satellites by using big telescopes that look for special types of light emitted by the satellites.

Ask students if anyone has ever navigated with a map on land? What was that like? Ask the same questions for air and water. Tell students that in today's lesson we are going to be talking about the different types of maps that are used in the different environments — land, sea and air.

Lesson Background and Concepts for Teachers

Navigating in Different Environments

Most of us know about navigating on land; we do it everyday when we are walking home or driving to the store. Navigation is used in all sorts of environments, and it is, therefore, always important to know your location. Navigating on land is very different than in the water, in the air, or in space because all each type of navigating requires different types of information. For example, a topographical map would not help you navigate on the sea. There are different navigation needs depending on whether you are traveling on land, sea, air or in space.

Dead Reckoning

Even though traveling in different environments requires different types of information, like maps, some things are common to all navigation. All navigation requires use of the concept of dead reckoning. Refer to Lesson 2 of the Navigation unit for more detailed information on dead reckoning.

Dead reckoning is the process of navigation by advancing a known position using course, speed, time and distance to be traveled. In other words, it is the process of figuring out where you will be at a certain time in the future if you hold steady the speed , time and course you plan to travel. Prior to the development of celestial navigation, sailors navigated by deduced (or dead ) reckoning . Columbus and most other sailors of his era used this method. In dead reckoning, the navigator finds his position by estimating the course and distance he has sailed from some known point. Starting from a known point, such as a port or harbor, the navigator measures out his course and distance from that point on a chart, pricking the chart with a pin to mark the new position.

Speed, Time and Direction

How did they know their speed? In Columbus' day, the ship's speed was measured by throwing a log over the front side of the ship. There were two marks on the ship's rail that were a measured distance apart. When the log passed the forward mark, the pilot would start a quick chant; when the log passed the aft (last) mark, the pilot would stop chanting. (The exact words to such a chant are part of a lost history of navigation.) The pilot would then note how much of the chant he recited, which would then enable him to determine the speed of the boat based on the distance traveled. This method would not work when the ship was moving very slowly, since the chant would be over before the log actually reached the aft mark. This approach may be expressed as a simple equation:

Speed x Time = Distance

This makes sense when you look at the units:

Miles divided by hours times hours equals miles.

In the equation, the hours cancel each other out, resulting in a distance in miles.

Along with the speed and distance, early sailors needed to know the direction of travel. This was accomplished using a compass. Once they knew their distance and direction, they could determine their current location based on their previous location.

So, what are the items we need to know to navigate using the dead reckoning approach?

Speed: We have to know how fast we are traveling.
Time: We need to know for how long we have been traveling.
Direction: We certainly need to know in which direction we are going.
Our previous location: It is good to know our speed, time and direction, but it is not enough unless we also know our exact last location.

We need to know all these variables to navigate.

Land Navigation

In previous lessons, we learned how to navigate on land. What types of information do you need to navigate on land?

Traveling by Car

Road maps: The first thing you do when you plan a road trip is get out a road map. It provides you with information on the choice of roads, the distance to a certain destination, and sometimes even suggests the quickest route to get there.
Street signs: A must for traveling in any city, they help you find your location on a city street map.
Mileage signs: These signs indicate the distance to the next city or town, and are very helpful to find your location on a road map.

Traveling by Foot

Topographical maps: These maps provide detailed information about the land surface.
Compass: This device helps you determine your direction. Used with a topographical map, you can triangulate to determine your exact position.

Sea Navigation

We have all traveled by car or on foot; it is easy to understand. But, what about traveling by sea? The sea is open and barren with no distinctive features. Dead reckoning is a very important skill for knowing where you are when traveling by sea. Because environmental conditions, such as sea currents or wind, can cause errors when using dead reckoning, it is important to look for landmarks. But, there are no natural landmarks on the sea. Luckily, people have made landmarks for us.

Aids in Sea Navigation

What other types of information would be helpful to know? What if you are traveling in a bay that is very shallow? You would want to know how deep the water is so that you do not run aground and damage your vessel. There are few natural landmarks that can be used. For this reason, people have made landmarks to use for navigating on water. Examples include:

Buoys: These floats with a bell or light are moored (anchored) in water. They are used as a landmark, a warning of danger, or a marker of a bay or channel.
Lighthouse: A tower with a bright, rotating light, located on or near shore to inform a sailor that land is nearby. Lighthouses are especially useful at night or in bad weather, when one's sight is limited. For example, a sailor could easily run into land if s/he could only see a distance of 20 feet.
Beacons: A generic term for some sort of sea landmark, such as a buoy or lighthouse.
Old shipwrecks: Ships do sink, and you definitely want to avoid them so that you do not sink your vessel also.

Nautical Charts

Land maps are not very useful when you are on the sea. Special maps designed for traveling by sea are called nautical charts. Some of their features are:

Depth: Nautical maps show depths under the water surface, just like topographical maps show elevation on the ground. Ship captains use these maps to avoid shallow areas or shipwrecks that could damage their ships.
Shoreline: Sailors like to know where land is located.
Landmarks: Such as shipwrecks and beacons.
Magnetic declination: Sailors must know the difference between true north and magnetic north, so that they can navigate properly.
Routes: Nautical maps show shipping lanes, and common and safe routes for sea vessels. Sailors use these lanes just like drivers use streets. Shipping lanes avoid shallow areas that can damage (or even sink) ships.
Currents: Nautical maps show the general direction in which the current flows at various locations.

Figure 1 depicts a section of a nautical chart for the San Francisco Bay in California. Note the many common features of the map (items with arrows pointing towards them) such as water depths, contour lines, the magnetic declination, and landmarks and beacons.

A portion of a nautical chart showing land and water areas, marked with depth contour lines, depths, a directional compass, and identifiers for beacons and landmarks.

Beacon Nomenclature

There are many types of beacons; some flash regularly, and some flash in a pattern, and some make sounds. Knowing the characteristics of a beacon helps a navigator identify the beacon, and therefore determine his/her location. On nautical charts, specific nomenclature (or naming system) is used to provide navigators with information to describe the type of beacon.

For example, the first beacon in the box in Figure 1 is marked: Fl R 4s 14ft 4M "4." The first descriptor denotes the type of beacon. In this case, F1 is a beacon with a flashing light, which helps navigators identify the beacon in inclement weather. The next descriptor indicates the color: R for red. The next descriptor shows the period of the flashes; this beacon flashes every 4 seconds. The next descriptor is the height of the beacon, 14 feet. After that is the range that the beacon can be seen from: 4 miles. And finally, the last descriptor is a beacon identifier, number 4.

As another example, in Figure 1 there is also a beacon marked: Q 12ft 6M. The Q stands for quick. This is a light that flashes about 60 times per minute, or once per second. Just like the previous example, the 12 ft. tells us that the beacon is 12 ft. high, and the 6M tells us that the beacon can be seen from 6 miles away.

Navigation in the Air

Pilots, like sea captains, must be able to navigate by dead reckoning. Sadly, this is not easy to do. What landmarks would you look for if you were a pilot? A street sign? A field? When airplanes were first invented, there were no good landmarks for pilots to use. In fact, many pilots would fly really low and slow, hoping to read the road signs to figure out which town they were near.

What kind of landmarks would be useful for pilots? Items such as railroad tracks, buildings, ranches, water or oil tanks, towns, lakes, rivers and highways can usually be seen from the sky. Recreational pilots in small aircraft find landmarks like these to be quite useful in determining their locations. But, a commercial airline pilot would not use these types of landmarks because commercial jetliners fly at about 35,000 ft., much too high to make out most of these landmarks. Can you imagine trying to identify landmarks that are seven miles away?

Aeronautical Charts

Pilots use aeronautical charts just like sailors use nautical charts. Anything that can help the pilot figure out where he is and help him land will be noted on the aeronautical chart. Aeronautical chart features include:

Elevation: Pilots must know the elevation of landforms in an area. For example, if there is a mountain in your flight path, you would want to know how high it is so that you can fly above it.
Airports: An aeronautical chart indicates the presence of airport elevation markers, runways (the road that you land on), flashing lights that show the pilot where to land, buildings and tanks. Locating these items helps pilots land safely.
Landmarks: Such as a river, golf course or bridge.

Scale of Aeronautical Charts

Traveling by foot or boat is slow compared to airplane travel. Since so much distance is covered quickly, typical aeronautical map scales are 1:500,000, meaning that an inch on the chart represents about 10 miles.

On the aeronautical chart in Figure 2 we can see a number of distinct features. The maximum elevation for any landform on the chart is 4,800 ft.; this is the highest point on that part of the chart, including buildings and natural features such as mountains. The chart also provides elevation contour lines. Helpful landmarks, such as ranches, a golf course and a trailer park, can be identified by pilots from the flying elevation of a recreational airplane like a twin engine Cessna. Most importantly, this map shows the two airports in the area. Notice the purple circle area and the two lines crossed within it, which are the runways. The purple outline around the whole airport shows the airport's airspace, which for safety reasons — unless a pilot is landing at that airport, he should not enter.

Space Navigation

Navigating in space is very different from other forms of navigation. Usually, sea drift or wind drift cause travelers by sea or air to move off course. But in space, the sources of error are far smaller. Once a spacecraft is in a known orbit, it perpetually travels along that orbit.

What Is an Orbit?

We all know that the Earth travels around the sun. This happens because the gravity of the sun is constantly pulling on the Earth. Like tying a ball to a string and swinging it around your head, the pull of the string on the ball is like the gravity of the sun pulling on a planet or satellite. Satellites travel around the Earth just like the Earth travels around the sun. The path that the satellite travels in is called an orbit. The satellite just keeps traveling along that orbit because there are no major sources of drift in space, such as wind or sea currents. Few conditions are present that would make satellites drift, such as small changes in gravity or the impact of meteorites, and the probabilities of these events are quite small. Therefore, it is not complex for knowledgeable people to predict where that spacecraft, moon or planet will be in an hour or a day. The methods used to predict the position of objects in outer space are just like dead reckoning, but with minimal drift and a constant speed.

Key characteristics that people must know when anticipating the position of objects in space include: How fast the object is moving, in what direction the object is moving and in what orbit it travels. Spacecraft send light waves down to the Earth to determine this information. By measuring properties of the light, spacecraft and satellites can calculate where they are and how fast they are going. Once their speed and location is known, computers in the spacecraft calculate in which orbit they are traveling. Once the computers determine the spacecraft's orbital path, its future path can be predicted using methods similar to dead reckoning.

Could you use a nautical chart to get home from school or to go hiking in a park? (Answer: No, because we do not live on the ocean.) Why is a nautical chart not helpful in this situation? (Answer: It tells us information about the sea, not the land.) Can you name for me some different environments that would require different types of maps? (Answers Land, sea, air and space each require different types of maps to help people navigate in those environments.)

What types types of information do you need to know to travel on the sea? (Answers: Water depth, location of channels, paths, obstacles [such as shipwrecks or reefs], harbors, etc.) What type of information do you need to know if you are traveling in the air? (Answers: Elevation of landforms, location of airports, big landmarks that you can see, etc.) These needs are similar: sailors on the sea need to know how deep the water is, and pilots need to know how high the land is. Smaller scale land maps are also helpful for hikers who need to know about obstacles (cliffs) so that they can avoid them, and about landmarks so that they can find their locations. Everybody needs to be able to navigate no matter where they are — on land, sea or air. The navigational methods and maps just need to be specific to each environment.

aeronautical chart: A map used for traveling by airplane.

airspeed indicator: An instrument on an airplane that tells how fast the plane is traveling relative to the wind.

attitude indicator: A graphical way to see the roll, pitch and yaw of an airplane.

beacon: Similar to a floating lighthouse. Beacons have lights that flash in many different patterns and colors to help sailors navigate. A sailor can find his location by looking for a specific beacon and determining which one it is.

buoy: A float with a bell or light that is moored (anchored) in water and used as a landmark, a warning of danger, or a marker of a bay or channel.

dead reckoning: A method to calculate the location of a person, ship, or spacecraft based upon where it was some time ago. Knowing the speed, direction and how much time has passed since you last knew where it was, you can find out where the person, ship, or spacecraft is at any time in the future.

lighthouse: A tower with a bright rotating light located on or near shores to tell a sailor that land is close. Lighthouses are especially useful to sailors at night or in bad weather.

nautical chart: A map used for traveling on water.

orbit: The path that a satellite travels around the Earth.

Pre-Lesson Assessment

Brainstorming: In small groups, have students engage in open discussion. Remind students that no idea or suggestion is "silly." All ideas should be respectfully heard. Ask the students:

What are the differences between traveling in an airplane and on foot? (Possible answers: You are up in the air, you are going faster.)

Post-Introduction Assessment

Ask the students and discuss as a class the questions below.

Has anyone has ever navigated with a map on land? On water? In the air? What was that like? (Tell students that in today's lesson we will learn about the different maps that are used in the different environments—land, sea and air.)

Lesson Summary Assessment

Numbered Heads: Divide the class into teams of three to five. Have students on each team pick numbers (or number off) so each has a different number. Ask the students a question (give them a time frame for solving it, if desired). Use questions in the Lesson Closure section. The members of each team should work together on the question. Everyone on the team must know the answer. Call a number at random. Students with that number should raise their hands to answer the question. If not all the students with that number raise their hands, allow the teams to work a little longer.

Exploring the Pros and Cons of Different Shipping Methods: Air, Sea, and Land

In today’s interconnected global economy, efficient transportation of goods across long distances is crucial for businesses and individuals. Shipping methods play a vital role in this process, and each method has its own set of advantages and disadvantages. By understanding the pros and cons of different shipping methods – air, sea, and land – we can make informed decisions about which method best suits our shipping needs. In this blog, we will delve into each method in detail, exploring their benefits and drawbacks.

Air Shipping

Air shipping, also known as air freight , offers several advantages and disadvantages. Let’s delve further into the pros and cons of this shipping method:

Pros of Air Shipping

Air shipping is renowned for its unparalleled speed. It is the fastest mode of transportation available for goods, making it ideal for time-sensitive shipments. Within a matter of hours, goods can be transported from one continent to another, ensuring prompt delivery and reducing transit times significantly.

Accessibility

Airports are spread worldwide, providing extensive global coverage. This accessibility is particularly crucial for businesses operating in remote or distant markets. Regardless of the destination, air shipping offers the convenience of reaching even the most isolated locations, facilitating international trade and business expansion.

Reduced packaging

Air shipments typically involve fewer handling points compared to other shipping methods, such as sea or land transportation. This streamlined process reduces the risk of damage to goods during transit. Consequently, businesses can benefit from lesser packaging requirements, minimizing the need for excessive protective materials and reducing overall costs.

Enhanced security

Airports adhere to strict security measures to ensure the safety of passengers, cargo, and aircraft. These security protocols minimize the chances of theft, tampering, or damage to goods during transportation. This aspect is particularly important for high-value or sensitive shipments, providing peace of mind to businesses and customers alike.

Cons of Air Shipping

One of the primary drawbacks of air shipping is its relatively higher cost compared to other shipping methods. The expenses associated with fuel, maintenance, and limited cargo capacity of airplanes contribute to these higher prices. As a result, air shipping is often less cost-effective for large or heavy shipments. Businesses need to carefully assess the value and urgency of their shipments against the cost implications of air freight.

Limited capacity

Airplanes have limited cargo space, which can pose capacity constraints, especially during peak seasons or for bulky items. This limitation may necessitate splitting large shipments into multiple consignments or exploring alternative shipping methods for oversized cargo. The need for coordination and potential logistics challenges arising from splitting shipments can add complexity to the shipping process.

Environmental impact

Air shipping has a larger carbon footprint compared to other shipping methods due to higher fuel consumption. Aircraft emit greenhouse gasses that contribute to climate change. If environmental sustainability is a priority, businesses may consider alternative shipping methods with lower emissions, such as sea freight or utilizing more sustainable aircraft technologies. Efforts to mitigate the environmental impact of air shipping include the exploration of biofuels, improved fuel efficiency, and carbon offset programs.

Air shipping offers unmatched speed, global accessibility, reduced packaging requirements, and enhanced security. However, its higher cost, limited capacity, and environmental impact are important considerations that businesses must weigh against their specific shipping needs and sustainability goals.

Sea shipping

Sea shipping offers businesses a cost-effective and versatile mode of transportation for their goods. With high cargo capacity and reduced fuel consumption, it proves advantageous for industries dealing with large volumes or heavy shipments. However, longer transit times, limited accessibility, susceptibility to external factors, and infrastructure requirements pose challenges that businesses must consider. This section explores the pros and cons of sea shipping, providing valuable insights for companies seeking efficient and reliable shipping solutions.

Pros of Sea Shipping

Cost-effective.

Sea shipping is known for its cost-effectiveness, particularly for transporting large volumes or heavy shipments. The substantial cargo capacity of ships allows for the efficient transportation of goods, reducing overall costs for businesses. By consolidating multiple shipments into a single vessel, economies of scale can be achieved, resulting in lower transportation expenses per unit.

High-cargo capacity

One of the significant advantages of sea shipping is the ability to accommodate significant cargo loads. Ships have large storage capacities, making them ideal for transporting bulky items or bulk shipments. Industries such as construction, mining, and manufacturing, which often deal with heavy or oversized goods, can benefit greatly from sea shipping’s high cargo capacity.

Reduced fuel consumption

Ships are generally more fuel-efficient than airplanes, resulting in lower carbon emissions per unit of cargo transported. Sea shipping offers a greener alternative for businesses concerned about their environmental impact. As sustainability becomes a growing priority for many companies, choosing sea shipping can contribute to their efforts in reducing carbon footprints and promoting environmentally friendly practices.

Versatility

Sea shipping provides a high level of versatility when it comes to transporting various types of goods. It can accommodate both dry and liquid bulk cargo, making it a viable option for industries such as agriculture, automotive, and chemicals. This flexibility allows businesses to ship a wide range of products using sea transportation, providing a reliable and adaptable solution for their shipping needs.

Cons of Sea Shipping

Longer transit times.

One of the main drawbacks of sea shipping is the longer transit times compared to air or land transport. Ships travel at slower speeds, and routes often involve multiple stops at different ports, leading to increased delivery times. Delays caused by weather conditions, port congestion, or customs procedures can further extend the transit time. Consequently, businesses requiring swift deliveries may find sea shipping less suitable, particularly for time-sensitive products or perishable goods.

Limited accessibility

Landlocked areas or regions far from coastal regions may have limited access to sea shipping routes. In such cases, additional transportation methods, such as trucking or rail, are required for inland delivery. This adds complexity and cost to the shipping process, as goods need to be transferred from ships to other modes of transportation. The lack of direct access to sea shipping routes can be a significant logistical challenge for businesses operating in certain locations.

Susceptible to external factors

Shipments via sea are subject to various external factors that can impact the delivery process. Inclement weather conditions, such as storms or heavy fog, can cause delays or even disruptions in shipping schedules. There is also the risk of piracy in certain areas, which can pose a threat to the safety of goods and personnel. Additionally, political unrest or conflicts in certain regions can affect sea routes, potentially leading to disruptions, diversions, or even loss of cargo. Businesses must consider these risks and implement appropriate measures to mitigate them.

Infrastructure requirements

Sea shipping relies heavily on well-developed port infrastructure to ensure efficient operations. Ports serve as critical hubs for loading and unloading cargo, customs inspections, and other essential logistics processes. Limitations in infrastructure at certain locations can impact efficiency and result in delays or additional costs. Insufficient port facilities, inadequate storage capacity, or outdated technology can hinder the smooth flow of goods and increase the turnaround time for shipments. Businesses should consider the infrastructure capabilities of ports when choosing sea shipping as a transportation option.

Sea shipping offers significant advantages such as cost-effectiveness, high cargo capacity, reduced fuel consumption, and versatility in transporting various types of goods. However, it also comes with challenges such as longer transit times, limited accessibility in landlocked areas, susceptibility to external factors, and infrastructure requirements. By carefully weighing the pros and cons, businesses can make informed decisions on whether sea shipping is the right choice for their shipping needs, considering factors such as time sensitivity, location, and risk mitigation.

Land shipping offers flexibility, cost-effectiveness for short distances, reduced carbon emissions, efficient tracking, flexibility in scheduling, and support for intermodal transportation. However, it has limitations such as limited range, road congestion, maintenance issues, and regulatory challenges at international borders. Understanding these pros and cons helps in making informed transportation decisions.

Pros of Land Shipping

Flexibility.

Land shipping offers a high level of flexibility, allowing goods to be transported directly from the point of origin to the destination without transshipment. This streamlines the shipping process and reduces the likelihood of delays or damage.

Cost-effective for short distances

For domestic or regional shipments over short distances, land transport is often the most cost-effective option. This is particularly true for smaller shipments or when the cost of air or sea transport outweighs the benefits.

Reduced carbon emissions

Land shipping typically has lower carbon emissions compared to air or sea transport, especially for shorter distances. This makes it an environmentally friendly choice for businesses aiming to minimize their ecological footprint.

Efficient tracking and monitoring

Advancements in technology have made it easier to track and monitor land shipments in real-time. GPS systems, telematics, and digital platforms enable businesses to closely monitor the progress of their goods, ensuring transparency and enabling timely updates to customers.

Flexibility in scheduling

Land transport offers greater flexibility in terms of scheduling compared to other modes of transportation. Businesses have more control over pickup and delivery times, allowing them to align their supply chain operations more effectively and meet customer demands efficiently.

Supports intermodal transportation

Land transport seamlessly integrates with other modes of transportation, such as rail and inland waterways, enabling intermodal transportation solutions. This combination of different transport modes enhances the overall efficiency and cost-effectiveness of the supply chain, especially for long-distance shipments.

Cons of Land Shipping

Limited range.

Land shipping is primarily suitable for shorter distances. Transporting goods across continents solely by land can be time-consuming and cost-prohibitive. For international shipments, land transport is often combined with other methods to cover the entire journey.

Road congestion and maintenance

Land transport is susceptible to road congestion, which can impact delivery times and increase the risk of damage to goods during transit. Moreover, the condition of roads and infrastructure maintenance can affect the overall efficiency and reliability of land shipping.

Regulatory challenges

Crossing international borders by land can involve complex customs procedures and documentation . This complexity can result in delays or additional costs for businesses, requiring careful planning and compliance.

Land shipping presents several advantages including flexibility, cost-effectiveness for short distances, reduced carbon emissions, efficient tracking, scheduling flexibility, and support for intermodal transportation. However, it also comes with limitations such as a limited range, potential road congestion, maintenance concerns, and regulatory challenges at international borders. By weighing these pros and cons, businesses and individuals can make well-informed transportation decisions that align with their specific needs and priorities.

Transportation Mode

There are many different modes of transportation used in logistics, including land, sea, and air shipment. Each mode has its own pros and cons with regard to cost, speed, efficiency, capacity, and reliability. However, logistics companies typically use a combination of multiple modes of transportation for their shipments in order to maximize their efficiency and reduce expenses.

Land transportation is the most common form of cargo shipment since it is relatively inexpensive and fast compared to other modes of transport. Trucking is the most commonly used form of land transportation due to its flexibility – trucks can travel long distances over roads or highways as well as into urban areas where they can access local streets. Railroads are also widely used for transporting goods over large distances because trains can carry a large amount of cargo and can travel at a high speed. However, because railroads tend to be more expensive than trucking, they are often used for particularly urgent and high-value shipments.
Sea transportation is another common mode of logistics transport that is widely used for transporting goods to remote locations that may not have easy access to other modes of transportation. Because ships can carry very large quantities of cargo and travel over long distances, sea transportation is often the most cost-efficient way of shipping goods along international routes. However, it is also slower compared to air or land shipment – this means that sea transport is often used only when the shipment is particularly valuable or time-sensitive.
Finally, air transportation is perhaps the fastest form of logistics transport – goods can be shipped to almost any location in the world within days using air shipment. However, because of the high cost and limited capacity of aircraft, air transportation is typically only used for shipments that are both very urgent and valuable.

Overall, the choice of transportation mode will depend on a variety of factors, including:

the type and size of cargo being transported,
its value ,
its urgency and the availability of other modes of transport at different locations along the route.

Logistics companies must balance these factors carefully when selecting their transportation modes to ensure that they are able to meet their customers’ needs at an affordable price.

Land, Air, and Sea Freight: Which One is For You?

Post author: Betina Tanedo
Post published: August 3, 2022
Post category: Service Provider

The world has benefitted from shipping in one way or another, even if not everyone realizes it. From groceries and mobile phones to new releases of your favorite shoe brand, freight forwarding has always been used for the movement of products.

Due to the rise of ecommerce, customers’ purchasing power and demands have significantly evolved. This development has led to a significant increase in global trade that requires business owners to be more creative in delivering their products. Fortunately, they now have different freight forwarding options at their disposal.

Thanks to developments in transportation, land, air, and sea freight solutions are now easily accessible. Our guide below will give you a brief rundown of these three freight services to help you decide which forwarding option is best for you.

Land Freight

This type of freight forwarding is the most preferred and used. Land freight enables the transportation of products by utilizing ground infrastructures like roads through trucks, trains, motorcycles, and cars. This type is the most popular option for short-distance forwarding due to its flexibility in pickup and delivery.

1. Land freight reaches points that are far from shipping ports

Since there are more options with the type of vehicle to use, items shipped via land can reach locations that are far from aircraft terminals and sea ports.

2. Technology allows your goods to be easily tracked and monitored

Technological advancements enable business owners and customers to monitor their shipments and deliveries through codes and reference numbers. This way, you won’t have to worry about losing your goods.

3. Land freight can transport various goods and can be combined with other means of transportation

Goods transported via land are easier to handle and monitor. Land freight provides for the safe transportation of all goods, including hazardous, liquid, and perishable items. It can also be integrated with other modes of transportation to complete the logistical process fully.

1. It covers less distance than air and sea freights

It covers less distance than the other two types. Land transport must also cross borders which typically requires paperwork. This results in delays, damage or loss of goods, and other related problems.

2. Traffic can delay the delivery time of your goods

In 2021, there were 4,951,662 units of vehicles registered in the Philippines, with the number continuously increasing yearly. With traffic as bad as Manila’s, you can expect delays in delivering your goods.

3. Capacity is more limited compared to other transports

Roads are not as wide as the sky or the sea, making land freight’s capacity the smallest of the three. The modes of transportation aren’t as vast as ships or planes either, so only small quantities of goods can be delivered.

Land freight is best used by businesses looking for a cost-effective shipment option. This type of freight works with smaller quantities of goods, so the cost is not as high as sea or air freight.

Air Freight

Air freight shipments are cargo transferred via an aircraft. These air carriers may be commercial or charter. The shipments travel much like other flights, from passenger and commercial aviation gateways to anywhere air carriers can fly and land.

1. Airlines offer air freight services to almost every point on Earth

Air service can reach even the most remote regions and nearly every point on the Earth, thanks to its extensive operating footprint.

2. The intense surveillance and security at terminals and reception areas reduce the risk of theft or damage

Air freight carriers benefit from tight restrictions and screenings. The intense surveillance and security at air terminals and cargo reception areas reduce the risk of theft or damage.

3. Air cargo transportation can be as quick as same-day delivery

The speed of air cargo transportation is the main benefit for shippers. Some even offer same-day deliveries. The fastest delivery times, as well as accurate estimated arrival and departure times, are provided by this mode of transportation.

1. Go-signals are dependent on the weather

Although weather impacts all modes of transportation, air freight is significantly affected. A few days of delay can be a problem if the delivery date is tight or perishable goods are on-board.

2. Planes cannot carry as much weight as sea cargo

The size and weight limitations are the next drawbacks of air freight transportation. Planes cannot carry as much weight as ships can since they are smaller and less robust. Therefore, some items can’t be shipped by air.

3. Quick but costly

You would have to pay a lot for the quick shipping time. Even if the delivery distance is the same, air freight travel is more expensive than the other modes of transportation. Air freight enterprises use weight calculations, while land and sea utilize volume calculations.

Air freight is best used for perishable goods that cannot stay in transit for more than a day or two and fragile shipments. Compared to shipping by trucks or cargo ships, items sent by air may be more protected against unintentional damage.

Sea Freight

Businesses employ sea freight as a shipping method to move massive quantities of cargo aboard. When moving heavy gear or a large number of goods, most enterprises choose this mode because it is cost-effective.

Sea freight is subject to fewer limitations than other forms of freight. Sellers, buyers, ocean carriers, freight forwarders, brokers, port authorities, and insurance companies are all involved in sea freight.

1. The most economical shipment solution

Shippers can find the most affordable freight rates in the ocean shipping sector, especially for long distances. According to some estimates, ocean freight shipment costs are often four to six times less than that of air.

2. Can accommodate big and heavy cargo

The ability of shipping firms to carry big, heavy, or bulky cargo is a significant benefit of sea freight shipping. Large cars, machinery, supplies for building, and other items are examples of such cargo. Loads too heavy or large for air freight or on-the-road transportation are rarely an issue aboard many commercial sea vessels.

3. Ships have the least amount of exhaust gas emissions, making them the most environmentally friendly

Modern shippers are giving their environmental impact more consideration. Multinational corporations favor using ocean freight as their primary means of transportation to minimize their carbon footprint.

1. Cargo takes too long to deliver compared to other freight services

The biggest disadvantage of sea freight is that delivery takes longer compared to other freight services. You can expect it to take days to arrive.

2. Packages may be lost or damaged due to weather-related issues

The dangers of ocean shipping are greater since it takes so long to deliver and get a package. The package may be damaged or lost due to weather-related obstacles.

3. Some regions of the world may lack the ports and terminals needed to accept large shipping vessels

It’s possible that some regions of the world lack ports and terminals, making it impossible for them to accept huge ships carrying containers. Dealing with container-based networks typically requires a substantial capital investment.

Sea freight is best utilized for shipments that must be handled with the best care. While it is the slowest, it is also the steadiest and most cost-effective option. Furthermore, since sea shipping usually travels by containers, it’s also best for businesses that send out and receive large quantities of items.

Notable Factors to Consider When Shipping

1. budget and price flexibility.

The price at which you sell the goods increases due to transportation costs; thus, you must consider your budget. Identify which shipping option offers the best value depending on the size or weight of the cargo. The types of goods and how quickly they need to be delivered impact the price and mode of transportation.

2. Speed of delivery

Air transport is ideal for long distances requiring urgent and quick delivery. Land transportation works well to deliver goods to more remote locations, whereas sea freight is best for companies requiring a large shipment to carry their burden.

3. Types of goods

The kind of commodities your freight forwarder has experience with should also be considered. If they have experience in the type of goods you carry, they can suggest the best carrier and packaging service and finish the paperwork swiftly and easily.

4. Volume and capacity

Do not forget to look at the company’s monthly shipment volume. This can help you determine whether the company can handle your cargo requirements or not, especially in terms of volume and capacity. You may export your goods safely and on time if the freight forwarding company has already shipped items to the same destination.

5. Industry expertise

The laws and rules governing shipping can be a real challenge. Fortunately, a reliable and knowledgeable freight forwarder can advise you on this because knowing and supplying the necessary information naturally comes to them.

Your chosen freight forwarder should assist you with finding the appropriate carrier, providing guidance on commodity codes, and verifying all necessary paperwork.

Cater to the World

Choosing a company with the right freight forwarding services can be difficult because of the different considerations. From weight to urgency and location, all these play a critical role in choosing land, air, or sea freight solutions. The best way to pick a carrier that will fit your needs is if you circle back to the pros and cons of all types and see which factors matter to you the most.

Freight transport types

Sea freight (ocean freight).

Sea freight (ocean freight) is the transportation of goods across the ocean via cargo / container ships. As one of the most cost effective types of freight shipping, sea freight accounts for an estimated 90% of all transported goods, 70% of which are shipped as containerised cargo. Specialist vessels are capable of carrying high volume, heavy cargo including bulk commodities such as grains, animal feed, fertilisers, salts and lumber as well as out of gauge equipment and products requiring specific facilities.

Pros of transporting cargo via sea freight:

The most cost effective form of freight shipping, typically calculated on a price per container basis
Possible to ship large volumes of cargo including large and heavy goods
A greener form of freight shipping, sea freight leaves a relatively small carbon footprint in comparison to air freight
Highly reliable, goods typically arrive with a 99.99% success rate

Cons of transporting cargo via sea freight:

Relatively slow transit times, often up to 10x slower than that of air freight
Risk of container ships experiencing delays in port or unable to load/unload cargo

Air Freight

Air freight utilises both passenger and cargo aircraft in order to quickly transport shipments around the world. A highly time efficient form of freight shipping ideal for those with tight deadlines to meet, goods destined for fast paced commodity markets are typically transported by air.

Pros of transporting cargo via air freight:

Fastest form of freight forwarding, air cargo arriving, door to door, from Asia to the UK can often take as little as 3 days
Reliable real time departure and arrival information
Wide range of global origins and destinations
Greater security for your goods

Cons of transporting cargo via air freight:

Considerably more expensive form of freight shipping, typically calculated on actual (gross) weight or volumetric (dimensional) weight
Limited capacity and not always able to ship large or heavy cargo
Incapable of transporting certain cargo including many hazardous substances
Considerable carbon footprint, airplanes emit 500 grams of CO2 per metric ton of freight per km of transportation

Land Freight

Pros of transporting cargo via road freight:.

Highly cost effective and economical especially over short distances
Efficient, sometimes a single customs document allows the seamless movement of goods through numerous countries and continents – although Brexit has rather spoilt this for the UK and Europe
Allows for a complete door-to-door service

Cons of transporting cargo via road freight:

Limited capacity dictated by size of vehicle
Transport times can be adversely affected by uncontrollable circumstances including traffic and inclement weather

Rail freight describes the transportation of bulk materials, intermodal containers, general freight or specialised freight in purpose-designed cars delivered by railway, often traversing multiple continents via long distance railway routes such as the Yiwu (China) – London (UK) railway line.

Pros of transporting cargo via rail freight:

The most efficient form of road freight, rail freight trains are capable of transporting the equivalent of 400 trucks worth of cargo
Environmentally friendly, each tonne of freight transported by rail reduces carbon emissions by 76 per cent compared to road freight
Cost effective when transporting freight across long distances
Reliable transit times and schedules, trains aren’t hindered by traffic or weather

Cons of transporting cargo via rail freight:

Not economically viable across shorter distances
Abnormal or hazardous cargoes cannot be moved in normal rail wagons, requiring specialist equipment

Privacy Overview

Very little of global food is transported by air; this greatly reduces the climate benefits of eating local

Transporting food by plane can come with a large carbon footprint. but very little of our food travels this way – just 0.16% of food miles are from air travel..

People often think that eating ‘local’ – buying foods which are produced close to home – is one of the most effective ways to reduce our carbon footprint.

This is certainly true for foods that are transported by plane. But the reality is that very little of our food is.

Most food travels by sea, not by air

One simple way to compare the means of transport for food is summing up how many kilometers planes with food freight travel; and compare this to how many kilometers trains, ships, and trucks travel.

But this does not give the complete picture because a boat can carry much more food for a given distance than a truck can. To give an informative comparison, we use a metric called ‘food miles’; this is calculated as the distance each transport method covers multiplied by the quantity of food transported (by mass). This gives us a comparison of food miles in tonne-kilometers.

The chart here shows the share of global ‘food miles’ by transport method. This data is sourced from the work of Joseph Poore and Thomas Nemecek, published in the journal Science in 2018. 1

As the data here shows, only 0.16% of food miles come from air travel. Most – nearly 60% – comes by boat.

You can see this data in absolute terms, in tonne-kilometers, in our chart on global food miles by transport method .

Whether food travels by sea or air makes all the difference

Transporting food by air emits around 50 times as much greenhouse gases as transporting the same amount by sea. More specifically, 0.023 kilograms of carbon dioxide-equivalents (CO 2 eq) per tonne-kilometer by sea, versus 1.13 kilograms CO 2 eq by air. We see these emission factors for different transport modes in the table.

For food that is transported by sea, transportation doesn’t actually add much to the carbon footprint. Since most of our food is transported by sea, transport emissions only account for 6% of the carbon footprint of food, on average. 3

But for those food items that travel by air, travel distance does have a large impact. We should avoid air-freighted goods where we can.

Which foods are air-freighted? How do we know which products to avoid?

Foods which are air-freighted tend to be those which are highly perishable. This means they need to be eaten soon after they’ve been harvested. In this case, transport by boat is too slow, leaving air travel as the only feasible option.

Some fruit and vegetables tend to fall into this category. Asparagus, green beans, and berries are common examples of air-freighted goods.

It is often hard for consumers to identify foods that have traveled by air since they’re rarely labeled as such. This makes them hard to avoid. A general rule is to avoid foods that have a very short shelf-life and have traveled a long way (many labels have the country of ‘origin’ which helps with this). This is especially true for foods where there is a strong emphasis on ‘freshness’: for these products, transport speed is a priority.

Emission factors for freight by transport mode (kilograms of CO 2 eq per tonne-kilometer) 2

Example: how does the footprint of vegetables change if they travel across the world by plane vs. boat?

Let’s take the example of asparagus.

If you live in the UK, you may have noticed on food labels that asparagus is often imported from Peru. They often come by plane. How does this affect their carbon footprint?

The average carbon footprint of asparagus is around 0.4 kilograms CO 2 eq per kilogram. Flying from Lima to London is around 10,000 kilometers. If we were to fly one kilogram of asparagus over this distance, this would emit around 11 kilograms of CO 2 eq [10,000km * 1.13 kilograms CO 2 eq per tonne-kilometer for flying / 1000 = 11.3 kg CO 2 eq per kg]. Suddenly the footprint of your asparagus changes from being a low-carbon food to a relatively high-carbon one, at almost 12 kg CO 2 eq per kg. It has a higher carbon footprint that a kilogram of chicken or pork.

It is the fact that it’s flown, rather than the travel distance itself that gives asparagus a large footprint in this example. If it traveled the same distance by boat, the travel emissions would be only 0.26 kg CO 2 eq per kg [10,000km * 0.026 kilograms CO 2 eq per tonne-kilometer for transport by boat / 1000 = 0.26 kg CO 2 eq per kg]. So its total footprint would be around 0.67 kg CO 2 eq per kg, which still makes it a low-carbon food option.

Poore, J., & Nemecek, T. (2018). Reducing food’s environmental impacts through producers and consumers . Science , 360(6392), 987-992.

These emissions factors by transport mode are those applied in the analysis by Joseph Poore and Thomas Nemecek (2018), published in Science . These emission factors are sourced from Ecoinvent v3.3 , a comprehensive database that is commonly used in international life-cycle analyses (LCA). Emission factors can span a range of values depending on factors such as the efficiency of the vehicle used; packing/loading density of freight; and distribution between passenger and freight allocation in shared transport; amongst other factors.

You might think that this figure of 6% is strongly dependent on where in the world you live – that if you live somewhere very remote, that the role of transport must be much higher. But this is not really the case.

Let’s take the example of beef from a beef herd. The average footprint of this beef is approximately 60 kilograms of CO 2 eq per kilogram of beef. Let’s compare the transport footprint of buying from your local farmer (who lives just down the road from you), versus someone in the UK transporting beef from Central America (approximately 9000 kilometers away).

Transporting food by boat emits 0.023 kilograms of CO 2 eq per tonne of product per kilometer. To transport the 9000 kilometers from Central America to the UK therefore emits 0.207 kilograms CO 2 eq [9000km * 0.023kg per tonne-kilometer / 1000 = 0.207 kg CO 2 eq per kg]. This is only equivalent to 0.35% of the total footprint of the 60 kilograms of CO 2 eq per kilogram of beef.

If you buy from your local farmer – let’s assume you walk there, and have zero transport emissions – your beef footprint is 59.8 kilograms CO 2 eq per kilogram [we calculate this as 60kg - 0.2kg]. It makes almost no difference.

Especially for foods with a large footprint, transport as a share of the food’s total emissions is fairly insensitive to the distance traveled.

The Geography of Transport Systems

The spatial organization of transportation and mobility

B.7 – Tourism and Transport

Author: dr. jean-paul rodrigue.

Tourism, as an economic activity, relies on transportation to bring tourists to destinations, and transportation can be part of the touristic experience.

1. The Emergence of the Tourism Industry

Since the 1970s where tourism became increasingly affordable, the number of international tourists has more than doubled . The expansion of international tourism has a large impact on the discipline of transport geography since it links traffic generation, interactions at different scales (from the local to the global), and the related transportation modes and terminals. As of 2016, 1.2 billion international tourist receipts were accounted for, representing more than 10% of the global population. The industry is also a large employer accounting for 10% of all the global employment; 30 tourist visits are usually associated with one job. 30% of the global trade of services is accounted for by tourism. Tourism dominantly takes place in Europe and North America , but geographical diversification is taking place.

Traveling has always been an important feature, but its function has substantially evolved. Historically, travelers were explorers and merchants looking to learn about regions, potential markets and to find goods and resources. The risks and exoticism associated also attracted the elite that could afford the large expenses and the time required to travel to other remote destinations. Many wrote realistic and even imaginary travel accounts. As time moved on and as transportation became more reliable, traveling became a more mundane activity taking place in an organized environment; tourism. In the modern world, traveling is more centered around annual holidays and can be reasonably well predicted.

As an economic activity, tourism is characterized by a high demand level of elasticity. As transport costs are significant for international transportation, cost fluctuations strongly influence demand. Therefore, transport is a key element in the tourism industry. The demand in international and even national transport infrastructures implies a large number of people to be transported in an efficient, fast, and inexpensive manner. It requires heavy investments and complex organization. Well-organized terminals and planned schedules are essential in promoting adequate transportation facilities for tourists, notably since the industry is growing at a fast rate.

Transport is the cause and the effect of the growth of tourism. First, the improved facilities have incited tourism , and the expansion of tourism has prompted the development of transport infrastructure. Accessibility is the main function behind the basics of tourism transport. In order to access sought-after destinations, tourists have a range of transportation modes that are often used in a sequence. Air transport is the primary mode for international tourism, which usually entails travel over long distances. Growth rates of international air traffic are pegged to growth rates of international tourism.

Transport policies and national regulations can influence destinations available to tourists. One dimension concerns the openness to tourism through travel visa restrictions , which vary substantially depending on the countries of origin of tourists. Unsurprisingly, travelers from developed countries, particularly Europe, face the least restrictions, while travelers from developing countries face a much more stringent array of restrictions. Another dimension concerns the provision of infrastructure. If the public sector does not cope with the demand in terms of transport infrastructures, the tourist industry might be impaired in its development. However, land transport networks in various countries are designed to meet the needs of commercial movements that tourism requires.

Tourism usually contributes enough to the local economy that governments are more than willing to improve road networks or airport facilities, especially in locations with limited economic opportunities other than tourism. There are, however, significant differences in the amount of spending per type of mode, namely between cruise and air transport tourism. Cruise shipping tourism provides much less revenue than a tourist brought by air travel. A significant reason is that cruise lines are capturing as much tourism expenses within their ships as possible (food, beverages, entertainment, shopping) and have short port calls, often less than a day. Tourists arriving by air transport usually stay several days at the same location and use local amenities.

2. Means and Modes

Tourism uses all the standard transportation modes since travelers rely on existing passenger transport systems, from local transit systems to global air transportation.

Car traveling is usually an independent transport conveyance where the traveler decides the route and the length of the trip. It is usually cheaper since road fees are not directly paid and provided as a public. It is the only transportation mode that does not require transfers, in the sense that the whole journey, from door to door can be achieved. Along major highway corridors, service activities such as restaurants, gas stations, and hotels have agglomerated to service the traffic, many of which touristic. Car transport is the dominant mode in world tourism (77% of all journeys), notably because of advantages such as flexibility, price, and independence. Tourists will often rent cars to journey within their destinations, which has triggered an active clustering of car rental companies adjacent to main transport terminals (airports, train stations) and touristic venues.
Coach traveling uses the same road network as cars. Coaches are well suited for local mass tourism but can be perceived as a nuisance if in too large numbers since they require a large amount of parking space. They can be used for short duration local tours (hours) but also can be set for multi-days journeys where the coach is the conveyance moving tourists from one resort to another.
Rail travel was the dominant form of passenger transport before the age of the automobile. The railway network usually reflects more the commercial needs of the national economy then holiday tourist flows which can make it a less preferred choice as a traveling mode. The railway systems of several countries, notably in Europe, have seen massive investments for long-distance routes and high-speed services. Due to the scenery or the amenities provided, rail transportation can also be a tourist destination in itself. Several short rail lines that no longer had commercial potential have been converted for tourism.
Air transport is by far the most effective transport mode. Notably because of prices, only 12.5% of the tourists travel by plane, but for international travel, this share is around 40%. Air transport has revolutionized the geographical aspect of distances; the most remote areas can now be reached any journey around the world can be measured in terms of hours of traveling. Business travelers are among the biggest users of airline facilities, but low-cost air carriers have attracted a significant market segment mainly used for tourism.
Cruises are mainly providing short sea journeys of about a week. Cruising has become a significant tourist industry. Cruise ships act as floating resorts where guests can enjoy amenities and entertainment while being transported along a chain of port calls. The international market for cruising was about 22.2 million tourists in 2015, which involves an annual growth rate above 7% since 1990. The main cruise markets are the Caribbean and the Mediterranean, with Alaska and Northern Europe fjords also popular during the summer season. This industry is characterized by a high level of market concentration with a few companies, such as Carnival Corporation and Royal Caribbean Cruises who account for about 70% of the market. The impacts of cruising on the local economy are mitigated as the strategy of cruising companies is to retain as much income as possible. This implies that tourists spend most of their money on the cruise ship itself (gift shops, entertainment, casinos, bars, etc.) or on-island facilities owned by cruise shipping companies.

3. Mass Tourism and Mass Transportation

Tourism transport can be divided into two categories:

Independent means of travel ; controlled by individual tourists who book them on their own. This mainly involves the private automobile, but also mass conveyances that are booked to travel on an individual basis such as regularly scheduled flights, rail connections, ferries, and even cruises.
Mass travel ; where tourists travel in organized groups. The most common form involves chartered buses and flights used for this single purpose.

When tourism was mainly for the elite, independent means of travel prevailed. However, the emergence of mass tourism and the significant revenue it provides for local economies required the setting of mass transportation systems and specialized firms such as travel agencies organizing travel on behalf of their customers. These firms were able to take advantage of their pricing power being able to negotiate large volumes of passengers for carriers and hotels. Some were even able to become air carriers, such as Thomas Cook Airlines and Air Transat, which are major charterers in their respective markets. Paradoxically, the growth of online travel booking services has favored the re-emergence of independent means of travel since an individual is able to book complex travel services, including transport and hotel accommodations. Thus, the segmentation of the travel industry is linked with the segmentation of the supporting transport systems.

The seasonality of tourism has an important impact on the use and allocation of transportation assets.

Air transport has a notable seasonality where tourism results in variations in demand, summer being the peak season. Because of this seasonality and the high cost of acquiring additional assets to accommodate peak demand, the airline industry has pricing power during peak touristic demand. This also leads the seasonal charter services to pick up the potential unmet demand. During the winter, charterers focus on subtropical destinations (e.g. Caribbean, Mexico), while during the summer there is more a focus on the European market.
Cruises also have a seasonality where many cruise lines are repositionning their assets according to variations in the destination preferences. During winter months, the Caribbean is an important destination market, while during the summer, destinations like the Mediterranean, Alaska, and Norway are more prevalent.

Associated data.

During the early stages of a new influenza pandemic, travel restriction is an immediate and non-pharmaceutical means of retarding incidence growth. It extends the time frame of effective mitigation, especially when the characteristics of the emerging virus are unknown. In the present study, we used the 2009 influenza A pandemic as a case study to evaluate the impact of regulating air, sea, and land transport. Other government strategies, namely, antivirals and hospitalizations, were also evaluated.

Hong Kong arrivals from 44 countries via air, sea, and land transports were imported into a discrete stochastic Susceptible, Exposed, Infectious and Recovered (SEIR) host-flow model. The model allowed a number of latent and infectious cases to pass the border, which constitutes a source of local disease transmission. We also modeled antiviral and hospitalization prevention strategies to compare the effectiveness of these control measures. Baseline reproduction rate was estimated from routine surveillance data.

Regarding air travel, the main route connected to the influenza source area should be targeted for travel restrictions; imposing a 99% air travel restriction delayed the epidemic peak by up to two weeks. Once the pandemic was established in China, the strong land connection between Hong Kong and China rendered Hong Kong vulnerable. Antivirals and hospitalization were found to be more effective on attack rate reductions than travel restrictions. Combined strategies (with 99% restriction on all transport modes) deferred the peak for long enough to establish a vaccination program.

The findings will assist policy-makers with decisions on handling similar future pandemics. We also suggest regulating the extent of restriction and the transport mode, once restriction has been deemed necessary for pandemic control. Although travel restrictions have yet to gain social acceptance, they allow time for mitigation response when a new and highly intrusive virus emerges.

When an emerging influenza virus is introduced to human populations, the pandemic potential of the virus becomes a public concern. Policy makers consider different interventions to contain and mitigate incipient pandemic growth. However, pharmaceutical interventions such as vaccines are not usually available in the early stage of pandemics. Public health measures such as travel restrictions then become essential in controlling pandemic spread.

Novel influenza A (H1N1), also called swine flu, is a novel influenza virus that caused its first illness in Mexico in 2009. Because of insufficient information regarding this particular infectious agent, the World Health Organization (WHO) declared the event the first global H1N1 influenza pandemic (H1N1pdm) on June 11, 2009. In a recent study, an estimated 284,500 deaths have been associated with H1N1pdm [ 1 ]. The high transmissibility of the virus has heightened public awareness of disease control measures. Hong Kong’s large-scale international travel pattern and high population density renders the Hong Kong population especially vulnerable. Nearly 300 severe H1N1 cases and 80 fatal H1N1 cases had been reported in Hong Kong at the end of the 2010 flu season [ 2 ]. The virus has been widely circulated locally, and lessening the disease burden now depends on implementing effective control measures.

The earliest applied H1N1pdm control measure imposed by the Hong Kong Government was travel restriction via travel advice and entry screening [ 3 ]. For highly-transmittable infectious diseases such as influenza, the traveling patterns of individuals play an essential role in geographical disease spread. Travel restrictions, a type of social control measure, have been evaluated in several epidemics including influenza [ 4 - 7 ], human immunodeficiency virus (HIV) [ 8 ], severe acute respiratory syndrome (SARS) [ 6 , 9 ], and, recently, the 2009 H1N1pdm [ 10 ]. Empirical statistics indicate that the influenza season was delayed following reduced flying activity caused by the US 9/11 incident [ 11 ]. Hufnagel et al . [ 9 ] further demonstrated that isolating a mere 2% of the largest cities was enough to halt the SARS outbreak. Nevertheless, the WHO considers travel restriction to be impractical in the majority of countries [ 12 ]. In addition, some studies have disputed the value of air travel restrictions in epidemic control [ 6 , 7 , 13 ]. Cooper et al . regarded that benefits accrued from suspending air travels is limited by the short serial interval of influenza. Hollingsworth et al . [ 6 ] concluded that containment of a pandemic influenza strain requires rigorous travel restrictions and small numbers of local infectious inhabitants. In Hong Kong, because the magnitude of travel restrictions imposed by travel advice and entry screening was small, its effectiveness in pandemic delay is disputable.

Despite these limitations, the impact of travel restrictions requires ongoing investigation. Previous studies focused on air travel restrictions alone [ 4 , 14 ], but in many cities, including Hong Kong, air travel is a secondary means of transport for arriving and departing travelers. Statistics show that more than half of the passengers arriving in Hong Kong annually enter by sea or land [ 15 ]. As shown in Figure Figure1, 1 , over ten million visitors per annum enter Hong Kong via land transport from Asia. Visitors from North America and Europe constitute a relatively high proportion of air transport arrivals. Therefore, to assess the true effectiveness of travel restrictions, air, sea, and land transport must all be incorporated into the evaluation. Additionally, most of the published mathematical models admit only those latent individuals who travel between countries. However, with limited screening sensitivity at the entry border points [ 16 , 17 ], a large number of infected cases could enter, thereby dramatically increasing the rate of local disease transmission [ 18 ].

Total arrival (in millions) by air, sea, and land transport. Forty-four countries were selected in total which contributed more than 95% of arrivals to Hong Kong.

Whereas travel restrictions can be imposed almost immediately, antiviral drugs require extended time for preparation. In Hong Kong, antiviral and hospitalization strategies were implemented about 3.5 months after the first global H1N1pdm import [ 19 ]. The main purpose of travel restrictions are to defer the pandemic, whereas antivirals and hospitalizations aim to reduce the transmission rate and severity of disease [ 5 ]. These strategies have proven useful in many influenza epidemics, including that of the novel H1N1pdm. Vaccination alone effectively mitigates most of the epidemics, by reducing the risk of a susceptible being infected, and thus the possibility of seeding the disease in the community. Nevertheless, vaccine design, development and public administration are lengthy processes. Current manufacturing capacity is insufficient to produce the vaccines within a few months following declaration of an influenza pandemic [ 20 ]. Hong Kong Government officials implemented the H1N1 vaccination program about nine months following the first global import [ 21 ], by which time the H1N1pdm had passed its peak. Low public acceptance of vaccine uptake during the H1N1pdm period compounded the issue. In one study, only 7% of subjects reported that they were ‘likely/very likely/certain’ to be vaccinated [ 22 ].

Impact of epidemic interventions is usually quantified by mathematical models. Clinical trial design is impractical for assessing the effectiveness of some interventions, such as face masks and isolation, because of ethical considerations relating to epidemics in general. By using mathematical models, the epidemic dynamics and intervention effectiveness can be determined. Such models can evaluate a range of interventions; isolation [ 23 ], quarantine [ 24 ], antiviral drugs [ 25 , 26 ], school closures [ 27 , 28 ], vaccinations [ 29 , 30 ] and face masks [ 31 ], among others.

In the study, we use the Hong Kong Governmental response to the 2009 H1N1pdm as a model case study to evaluate the effectiveness of travel restrictions of different magnitudes and transport modes i.e. air, sea, and land, combined with other interventions, namely antivirals and hospitalizations, in the event of a novel influenza virus. The impact is assessed by simulations from an epidemic model. We also investigate the effects of changing important parameters, including reproduction numbers in non-local visitors to Hong Kong, screening sensitivity at entry border points, and date at which travel restrictions are imposed. The results provide valuable information to policy-makers and public health experts in the event of similar future pandemics.

Population and transportation

Population data were extracted from the International Database (IDB), U.S. Census Bureau [ 32 ]. The individual probability of travel for each country was calculated as the daily travel rate divided by the population size. The arrival data were extracted from visitor arrival statistics provided by the Hong Kong Tourism Board [ 15 ]. These statistics include the total number of arrivals by country, together with their modes of transport. Forty-four countries, collectively contributing more than 95% of annual arrivals to Hong Kong, were selected for the analysis (Figure (Figure1). 1 ). The yearly frequency of departing Hong Kong residents by different transport modes were collected from the Census and Statistics Department, Hong Kong [ 33 ]. The data are listed in Additional file 1 and are assumed to be uniformly distributed on a daily scale.

Disease transmission model

We extended the discrete stochastic SEIR model [ 34 - 36 ] to study the H1N1pdm dynamics and the impacts of local interventions. The stochastic approach differs from that of deterministic models [ 4 , 37 - 41 ]. In our model, foreign virus arriving by air, land, and sea transport adapts and establishes in a local community with inherent uncertainty. Introducing this chance effect into the epidemic dynamics enhances the realism of the model. The model outputs are the deferred time period and the illness attack rate (AR) (defined as the number of new infected cases per head of population during a given time period).

All individuals in the local population were assumed to be susceptible, and the average latent and infectious periods were set to 1.45 and 2.9 days, respectively [ 10 , 42 ]. The population, N , was divided into four classes: susceptible ( S ( t )); exposed ( E ( t )); infectious ( I ( t )); and recovered ( R ( t )), at each time point t . Because no information was available on cross-immunity from past influenza infections, the initial population was set at 100% susceptible. Once susceptible individuals became infected, they advanced to the latent (non-infectious) stage. Following the latent period, they became infectious and could transmit the disease to other susceptible individuals. A number of individuals moved to the next compartment with a defined probability. The number of individuals advancing to each stage was assumed to follow a binomial distribution.

Disease transmission from travelers

In the disease transmission model, latent ( I M k E ( t ) ) and infectious ( I M k I ( t ) ) travelers arrived from 44 foreign countries by transport k -th and were assigned to compartments E ( t ) and I ( t ), respectively. Because the screening sensitivity at the border points of entry was limited, a proportion (1− ν ) of infectious cases were imported to Hong Kong, an approach not considered in other global patch models [ 7 , 10 ]. The number of cases imported to the local city was also assumed to be binomially distributed, with a probability equal to the chance of travel via the specified transport mode.

To allow for spatial heterogeneities between non-local countries, case numbers for each country were generated from discrete time SEIR models assigned independent reproduction numbers ( R 0 ), defined as the average number of secondary infections induced by a typical infectious individual in a wholly susceptible population. The magnitude of R 0 depends on the individual contact rate, disease transmissibility, and the duration of infectiousness; hence, R 0 is expected to differ between countries. In this paper, the R 0 of foreign countries were estimated by the initial exponential growth rate method [ 43 ] assuming no intervention during the early stage of H1N1pdm. They were fitted by daily counts of laboratory-confirmed infected cases in each country, obtained from pandemic H1N1 situation updates archived in the World Health Organization (WHO) [ 44 ] and the European Centre for Disease Prevention and Control (ECDC) [ 45 ]. Several local exposed ( E X E ( t )) and infectious ( E X I ( t )) cases were removed from the compartments based on the proportion of travel by the specified means of transport. Simulation was started from the day of initial global import. The effect of varying the R 0 s of specified foreign countries by 20% was performed. The details of disease transmission from travelers are provided in Additional file 1 .

Control measures

The mathematical model assesses the effectiveness of: (i) travel restrictions (for different transport modes) and (ii) local antiviral and hospitalization interventions. Travel restrictions were supposed to take effect on the day following the first global onset case. Different start dates were tested in a sensitivity analysis. The antiviral and the hospitalization strategies were implemented locally 3.5 months following the first global onset case, echoing the strategies employed by the Department of Health, Hong Kong [ 19 ].

Travel restrictions relating to sea, land, and air travel

We imposed 90% and 99% travel restrictions ( f k ), on different transport modes k . The term ‘travel restriction by f k ’ meant allowing only a fraction of (1− f k ) import individuals to be transported to Hong Kong from overseas through transportation k . We also considered only one-third ( ν ) of those (1− f k ) imported infectious cases as successfully identified positive cases at the entry borders in the baseline scenario [ 16 ]. The screened positive individuals entering Hong Kong were transported to hospital for further examination [ 3 ]. Confirmed cases were recommended to undertake voluntary quarantine. We assumed that all identified cases accepted voluntary quarantine. Screening sensitivities of 95% and 5%, and travel-restriction start dates of three and five months following the first global import, were also evaluated (Additional file 1 ).

Antiviral and hospitalization

We assumed that 12% ( p T ) of the infectious subjects were offered antiviral and 6% ( p H ) of the infectious subjects were hospitalized, based on influenza pandemic records [ 23 , 25 ]. The remaining 82% ( p U ) of infectious individuals were untreated. The antiviral reduces infectiousness ( ψ ) of individuals by 60% [ 46 ]. Either intervention reduce the average infectious period by 1.5 days [ 47 ]. Compartments for antiviral T ( t ) and hospitalization H ( t ) were developed separately in the model for individual assessment of the treatments. The stochastic system is

We denote bin ( m, n ) as a binomial distribution with probability m and number of total individuals n . The distributions of the classes are

where β is the disease transmission rate and 1/ α is the average latent period. The probability of a susceptible person becoming infected is 1− exp [− β [ I ( t ) + (1− ψ ) T ( t ) + H ( t )]/ N ] during time step Δt . γ R , γ T , and γ H specify the removal rates from the infectious state, the antiviral treatment state, and the hospitalization state, respectively. The details of the mathematical methodology and the simulation are provided in Additional file 1 .

Epidemic evolution and baseline scenario

The H1N1pdm is seeded according to the start dates of each country (listed in Additional file 1 ). The earliest epidemic was seeded in Mexico on March 11, 2009 [ 48 ]. For each country, the number of infected cases was generated from the discrete-time SEIR model, based on the estimated reproduction number.

Since the Hong Kong Government confirmed the first imported case of H1N1pdm on May 1, 2009 [ 49 ], the initial numbers of latent cases and infectious cases were iteratively estimated, thereby minimizing the difference between the reported date and the simulated first passage time (FPT). Allowing for stochastic variability, the baseline transmission rate was estimated for the first two months following the day of the first local import, in the absence of travel restrictions and intervention. Local daily surveillance of confirmed infected cases (May 1, 2009 to June 30, 2009) was available from press releases on human swine flu, published by the Department of Health, Hong Kong [ 50 ]. The range of R 0 values encompassed mild and severe scenarios.

Scenarios with no interventions

The local baseline R 0 was estimated at around 1.4. Values of R 0 were chosen to simulate mild ( R 0 =1 . 1) and severe ( R 0 =1 . 7) influenza outbreaks in Hong Kong, and were consistent with those reported in previous studies [ 48 , 51 ]. In foreign countries, R 0 ranged from 1.1 to 1.9. In the baseline scenario ( R 0 =1 . 4), the median FPT and first one hundred passage time (FHPT) of infected cases entering Hong Kong were 55 and 90 days, respectively (Table (Table1). 1 ). Because the H1N1pdm was initiated in the Americas, the primary means by which the infected cases arrived in Hong Kong during the fourth month was air travel (Figure (Figure2). 2 ). The number of cases imported by air transport exceeded that of land transport during the first six months. Thereafter, because the emerging virus had circulated to most of the Asian countries, including China, the number of cases imported by land transport increased exponentially. Because ships constitute a minor transport mode to Hong Kong, they delivered few cases throughout the pandemic period (Figure (Figure2 2 ).

Median FPTs and FHPTs (in days) with confidence intervals (CI) at the baseline scenario

Travel restrictions took effect on the day after the first global case onset. The medians and the non-parametric 95% confidence intervals were obtained from 100 simulation runs.

In the absence of control measures, and setting Hong Kong R 0 =1 . 4, the seven months’ cumulative AR was close to that of the final AR (Figure (Figure3A). 3 A). In a mild local scenario ( R 0 =1 . 1), the cumulative AR was a mere 2% after five months, and after seven months, had reached just two-thirds the final cumulative AR (Figure (Figure4A). 4 A). In a severe local scenario ( R 0 =1 . 7), the H1N1pdm had nearly terminated after seven months, and the cumulative AR exceeded 70% (Figure (Figure4 4 E).

The medians were obtained from 100 simulation runs; AH = antiviral and hospitalization.

Impact of the interventions

Among the three kinds of transport, disease spread was most effectively delayed by restriction on air travel. Air travel restriction delayed the FPT and FHPT by one week relative to the no-intervention control case (Table (Table1). 1 ). The peak time might have been delayed by two weeks if a single 99% air travel restriction had been imposed (Figure (Figure5C). 5 C). The pandemic established in China six months following the first global import to Hong Kong; the strong land connection between the two countries significantly enhanced the number of imported cases. Therefore, suspending both air and land transport could delay the passage time by a further one to two weeks, and the peak by about 3.5 weeks (Figure (Figure5A 5 A and C).

The absences and the presences of the uses of antiviral and hospitalization are illustrated in the left-hand column ( A and C ) and in the right-hand column ( B and D ), respectively. The upper panel ( A and B ) and the lower panel ( C and D ) illustrate the 90% and the 99% restriction rescaling, respectively.

The solid lines represent the average cases; the dotted lines represent the corresponding lower and upper bounds of the 95% non-parametric confidence intervals; AH = antiviral and hospitalization.

Travel restrictions on all transport modes most effectively delayed the spread of the H1N1pdm. As shown in Figure Figure5, 5 , the difference between 90% and 99% transport reduction was apparent only when all three transport modes were restricted. Once the volume of all transports was reduced by 90%, FPT and FHPT were retarded by one month relative to the control case. 99% travel restriction delayed the FPT and FHPT by an additional two months (Table (Table1). 1 ). 90% and 99% restriction of all transport modes deferred the peak for about six weeks (Figure (Figure5A), 5 A), and 12 weeks (Figure (Figure5C), 5 C), respectively.

Nevertheless, blocking of sea or land transport alone cannot prevent disease spread; it did not confer any large reduction in the five and seven months’ cumulative ARs. Even with sea transports reduced by 99%, the peak is delayed by only one week, relative to the control case (Figure (Figure5 5 C).

In reducing attack rate, antiviral and hospitalization administration (AH) proved more promising than travel restrictions. Neither 90% nor 99% travel restrictions reduced the epidemic magnitude by more than 10%. Implementation of AH on a proportion of infected individuals could halve the peak rate, and reduce the final cumulative ARs (relative to the case of no intervention) from 58% to 37% (Figure (Figure5B 5 B and Figure Figure3B). 3 B). However, the peak time of epidemic was only slightly delayed.

Combining travel restrictions with AH, the impacts on mitigation are greatly enhanced. Air travel restrictions plus AH delayed the peak time by more than three weeks (Figure (Figure5B 5 B and D). A 99% restriction of both air and land travel delayed the peak time by more than six weeks (Figure (Figure5D). 5 D). Imposing AH plus a 99% restriction on all transport modes flattened the epidemic curve more effectively than did AH plus 90% travel restriction. This strict condition greatly repressed the cumulative ARs, limiting them to around 1% (Figure (Figure3D). 3 D). Most importantly, the peak was delayed by approximately five months (Figure (Figure5D). 5 D). Supplemented by AH, total travel restriction reduced the final cumulative AR to about 14%.

In a milder local scenario ( R 0 =1 . 1), travel restrictions not only effectively delayed the H1N1pdm, but also flattened the incidence curve. Suspension of air travel remained the best choice among the three transport modes for repressing the cumulative ARs (Figure (Figure4A 4 A and C). Because the disease transmissions were comparatively slow and mild, 90% land import restriction was sufficient to decrease the peak ARs by one-third (Figure (Figure6A 6 A and C). Besides reducing the peak incidence by 25%, 99% restriction of all transport delayed the peak time by one year following the first global import. As shown in Figure Figure6B 6 B and D, combining AH and travel restrictions resulted in significant peak reduction. Restricting all travel routes as well as administering AH, the spread of the local epidemic was halted; the 99% travel restriction retained the final cumulative AR at around 0.2% (Figure (Figure4B 4 B and D).

Daily incidences for different control measures vs. days for the mild ( R 0 =1.1 ) and the severe ( R 0 =1.7 ) scenarios. The absences and the presences of the uses of the antiviral and hospitalization are illustrated in the left-hand column ( A , C , E , and G ) and in the right-hand column ( B , D , F , and H ), respectively. The first and the third panels ( A , B , E , and F ), and the second and the forth panels ( C , D , G , and H ) illustrate the 90% and the 99% restriction re-scalings, respectively. Day one was taken to be March 11, 2009 (the time of the first global case onset). The solid lines represent the average cases; the dotted lines represent the corresponding lower and upper bounds of the 95% non-parametric confidence intervals; AH = antiviral and hospitalization.

Incoming travel restrictions became less effective (especially where ARs was concerned) as the contagion level of the influenza virus increased to R 0 = 1 . 7. The rapid disease transmission rate raised the five months’ cumulative AR to an average of 22% (Figure (Figure4E 4 E and G). Imposing 99% restriction on all transport modes remained sufficient to retard the disease spread, deferring the epidemic peak time by about eight weeks (Figure (Figure6G). 6 G). However, under 90% total travel restriction, no significant delay was observed. Supplementation by AH became more important in this scenario (Figure (Figure4F). 4 F). Because the incidence growth was now suppressed by AH, travel restrictions more effectively repressed the epidemic. Imposing a 99% restriction on all transport, the seven months’ cumulative AR was restrained to 4% or less (on average; Figure Figure4H), 4 H), with an approximate delay in peak time of 12 weeks (Figure (Figure6 6 H).

Effect of R 0 from non-local countries

In our study, we varied the R 0 s from 44 foreign countries by 20%, and re-evaluated the model outputs. The changes in foreign R 0 s affected the number of imported cases, implying that growth of a local epidemic depends upon the passage times of the cases. With reductions of R 0 s, imposing restrictions solely on air travel nearly halved the cumulative ARs. A 99% all-transport restriction was sufficient to halt the local spread (cumulative ARs attain < 0.1%) after seven months (with or without AH administration). It maintained the seven months’ cumulative AR at around 12% even with a 20% increase in R 0 .

Effect of screening sensitivity at entry border points

Increasing the screening sensitivity at the entry border slightly retards the local epidemic. In most of the travel restriction scenarios, the additional FHPTs delay imposed by the strict 95% screening sensitivity and the relaxed 5% screening sensitivity was, at most, one to two weeks.

Effect of implementation date on travel restrictions

Imposing travel restrictions five months after the arrival of the first global case is ineffective. Even with a total transport reduction of 99%, the reduction in the cumulative ARs was found to be negligibly small. By comparison, allowing a three-month gap between arrival of the first global case and imposition of travel restrictions, the seven-months cumulative AR could be restrained at around 2% by imposing AH plus 99% restriction on all transport modes.

Non-pharmaceutical interventions such as travel restrictions are immediate means by which to slow pandemic growth and to extend the time available for vaccine production. Here we collected statistics on arrival numbers in Hong Kong from 44 countries via air, sea, and land transport [ 15 ]. These data were input to a mathematical model to evaluate the impact of travel restriction on different scales and by different modes, combined with other government strategies (namely, antivirals and hospitalizations), using the 2009 H1N1pdm as an example. From our results, we infer that the main connecting route and transport mode between source and destination (in this instance, air travel from the Americas/Mexico to Hong Kong), should be targeted for travel restrictions in a pandemic. This is in addition to suspending travels from large, high-density cities [ 9 ]. The emerging 2009 H1N1pdm virus had circulated to most Asian countries, including densely-populated China, six months after the first global case was reported. The number of imported cases from China to Hong Kong by land transport thereafter increased exponentially. Reducing land travel could have significantly lowered the number of import transmissions. In mild cases, such a restriction reduces the proportion of peak incidence and delays the peak time by up to one month. However, suspending travels on a single route only slightly decreases the peak incidence and the final epidemic size. Restricting either sea or land transport, but not both, confers little advantage in terms of disease spread.

Travel restrictions may not be effective at reducing epidemic size. Based on our results, antivirals and hospitalization lower the disease incidence as well as the final epidemic size, but do not prevent the import of contagious cases or delay the peak time. In most scenarios, imposing AH on a proportion of infected individuals (< 20%) moderately mitigates the severity of the pandemic, reducing the peak incidence by half. Several previous studies have lauded AH as an effective new epidemic control measure [ 5 , 24 , 52 ]. On the other hand, when AH and travel restrictions are imposed together they supplement each other, further mitigating the pandemic. Since imposing AH suppresses the growth of local transmission, the number of local infected sources is reduced, while travel restrictions prevent the import of fresh infectious sources. Imposing both interventions thus considerably extends the peak time. When rigorous restriction on all transport modes is combined with AH, the delays (peak appearing after the 10th month) are possible to allow vaccine production (i.e. beyond the nine months following the first global import to Hong Kong, during which time a vaccine program was developed and administered to the local public).

The effectiveness of travel reductions depends upon the rate of epidemic growth in different foreign countries [ 6 ]. If control measures had been responsible for reduced transmission in foreign countries (modeled by decreasing the R 0 s by an average of 20%), a 99% restriction on all external transport modes might have halted the local spread. In any case, increasing the screening sensitivity at the entry border points conferred a one to two week delay benefit. In reality, some individuals would refuse to undertake voluntary quarantine despite screening positive at the border. Such refusals would decrease the sensitivity for screening of quarantined symptomatic cases. Although the true screening sensitivity may not match our model settings i.e. 30%, we showed that screening sensitivity exerts only a secondary effect on epidemic delay. In the simulation results, the average maximum number of the screened import cases is 928 (95% confidence interval: 895-961), whereas there are 1400 isolation beds in 14 major hospitals in Hong Kong, which was set by the government after SARS [ 53 ]. Thus, the control measure would unlikely entail a capacity problem in Hong Kong. Our findings also imply that restrictions be imposed no later than three months following the first infectious global import. Implementing travel restrictions at or beyond the end of the fifth month would be almost useless, because the local epidemic would by then have evolved to a mature stage, in which disease transmission would depend on the local exponential increase in cases, rather than on successive imports.

In the study, we focused on a major city, Hong Kong, as a high-density, well-traveled region especially suited to the assessment of travel restrictions. Travel restrictions reduced the illness rate only in the event of mild local disease transmission intensity. In some rural areas or island countries, the disease transmission intensities as well as the reproduction numbers remain at low levels due to limited human mobility and contacts. In addition, these areas may be infrequently visited by foreign travelers. Such areas may benefit significantly from travel suspension. In some studies [ 54 , 55 ], beneficial delays in epidemic establishment have been reported, as a result of blocking imported cases. Apart from travel restrictions, there are other public health measures such as regular hand washing, voluntary quarantine, and school closures to reduce the impact of influenza pandemic. Compared with travel restrictions, school closure is easier to implement in a community. Past influenza pandemics have shown a particular focus on disease transmission in children. School closures resulted in a positive effect proven to be effective in reducing the disease transmission during the H1N1pdm [ 28 ]. Nevertheless, while school closures and antivirals are good for transmission reduction, they may not be for buying more time in epidemic preparation. Closing schools for a long time would induce social and economical impacts, whereas closing schools for a short period of time may not be sufficient to show effects on community transmission [ 56 ]. Other social distancing measures like cancelling public gatherings or international events raise questions about which sizes of public gatherings would warrant cancelling. These factors could be considered in future research.

Several limitations are present in our study. Restrictions for inbound travel could be beneficial to the pandemic mitigation but not outbound travel restrictions. Restrictions for outbound travel could lead to a worse situation of a pandemic growth after successive local cases arise. This is because the departure frequency is more than the arrival frequency in Hong Kong (Additional file 1 : Table S1), and the excess proportion of individuals are restricted to stay and infect or transmit influenza virus to others. So there are increases to the attack rates for this scenario. Nevertheless, the restrictions on outbound travel to prevent spreading to other countries is especially beneficial for those with limited resources of pandemic prevention. Outbound travel restrictions would be better imposed during the containment phase in order to prevent a global spread of pandemic virus. As our study does not incorporate the comprehensive traveling network between countries required for a global viewpoint of pandemic spread, we cannot completely determine the value of outbound travel restrictions. Moreover, we were unable to quantify the infection risk for outbound susceptible travelers during their trip abroad because of limited information regarding their contact patterns. Although outbound passengers may become infected during their time abroad, they have nonetheless escaped from local infections. Our estimated R 0 for Hong Kong was 1.4, close to that of the global median (Additional file 1 : Table S2). The similar disease transmission intensity between countries would unlikely incur large infection-risk differences between outbound and local susceptible individuals, provided that the periods of H1N1pdm in different countries are not widely spaced. In addition, all travelers are assumed to undertake a single-step journey to their destination, and no adjustment for multi-step journeys is admitted in the model. Nevertheless, previously reported reports reveal little quantitative difference between single- and multi-step travel [ 57 ]. More importantly, enforcing rigorous travel restrictions has been undoubtedly unrealistic to date, since such restrictions would substantially degrade the local economy. In 2009, [ 58 ], tourism-related activities such as accommodation services, retail trade, transport services, and food and beverage services contributed 2.6% (US$5,200 million) to Hong Kong’s Gross Domestic Product (GDP). Large travel reductions thus incur high economic loss. However, increasingly severe diseases, such as SARS and influenza A (H1N1), have entered our society within recent decades, and have affected wider age groups than have past epidemics. The emergence of a highly lethal virus is feasible in the near future. In mitigating viral pandemics, the benefit to be gained from imposing travel restrictions as an adjunct to other effective control measures must be balanced against potential economic impacts. A comprehensive cost benefit analysis will thus be addressed in our future research.

Conclusions

Our study suggested that air travel restrictions should be priorities for consideration when a new influenza pandemic begins overseas. When the pandemic is initiated in China or other places where there is land travel to Hong Kong, land travel restrictions should also be a priority. If restrictions are able to cover 99% travelers with the use of antiviral and hospitalization, the resulting pandemic delays are possible to allow vaccine production; if the restrictions cannot cover 90% or more travelers, then the peak time will happen sooner. In this case, control measures such as antiviral should be enacted earlier to alleviate the epidemic growth. To date travel restrictions have yet to gain widespread social acceptance, but the benefits may significantly outweigh the costs, especially when a new and highly intrusive virus emerges.
