The transportation industries—airline, railroad, shipping, and trucking—are networks involving both a flow and a grid. The flow element relates to what is being transported—e.g. airplanes and trains—and the grid is the physical infrastructure used to manage the flow—e.g. airports and air traffic control. Some transportation industries have been freed of extensive federal regulation, including railroads and trucking. However, air travel had only its flow element—the airlines—economically liberalized under the 1978 Airline Deregulation Act.
