BTS was established by Congress to compile, analyze, and make accessible information on the nation’s transportation system; to collect information on intermodal transportation and other related areas as needed; and to enhance the quality and effectiveness of the Department of Trans- portation’s statistical programs through research, the development of guidelines, and the promotion of improvements in data acquisition and use.
