2 The Transportation System and Equipment
The U.S. transportation system is an extensive, interconnected network of public and private roads, airports, railroads, transit routes, waterways, terminals, ports, and pipelines. Millions of people and businesses rely on this expanding system to get to work, conduct business, ship goods within the United States and abroad, and travel on vacations. The transportation system links regions and joins urban and rural areas, and connects the United States (people and goods) with the rest of the world.
