Table 3-2: Number of U.S. Vehicles, Vessels, and Other Conveyances: 1980-2005
A vast number of vehicles and vessels move goods over the transportation network. The number of commercial trucks climbed 46 percent between 1980 and 2005. In comparison, the number of rail freight cars has declined since 1980 with improved utilization and the deployment of larger cars. The number of U.S.-flag water vessels increased slightly over the same period while the world fleet expanded substantially in number and size of vessels.
