If you ask each of your classmates the question "What is Transportation?" you will, more than likely, get a different answer from each of them. There are primarily two reasons for this:

1. To the average person, transportation is transparent. It's there, it's always been there, and there is no reason to believe that it's not always going to be here. This is because the hundreds of thousands of people who work behind the scenes to make America's transportation system successful are very good at their jobs. Its through their efforts that people are able to get in their cars to drive to work, go to school, go to the store, go to the movies, take a vacation, or go to the hospital, all within a reasonable amount of time.
2. Transportation is a very big field. It has many specialized areas. Trucking, railroads, airlines, shipping, and road construction are just a few of these areas.

In this module, we will help you define Transportation by examining the various components that cause it to impact our daily lives. We will look at transportation from the air, sea, rail and highway. Then we'll look at how all of these forms of transportation, and the people who make them work, come together to safely move people and products across the world in a manner that improves all of our daily lives.
