Transportation -- Moving people and goods from place to place.

Modes of Transportation -- Automobiles, buses, trains, trucks, ships, airplanes, and bicycles are different types of "modes" of transportation.

Intermodal Transportation Systems -- Make life easier for travelers' switching from one type of transportation to another. Intermodal systems link all the different modes of transportation together moving people and goods. For example: when a family takes a trip they may take a car or a subway train to the airport, then take an airplane to another city. Once they arrive at their destination, they may take a bus or taxicab from the airport to the hotel.

Intelligent Transportation -- "Intelligence" refers to the underlying computer/telecommunications technologies used in ITS applications.

More than Asphalt, Concrete, and Steel -- Transportation is about providing all Americans with access to opportunities. In the words of DOT Secretary Rodney E. Slater, "Transportation is about more than concrete, asphalt, and steel. It is the means by which ... all people pursue happiness."
