Congress requires the Bureau of Transportation Statistics (BTS) of the Research and Innovative Technology Administration to report on transportation statistics to the President and Congress. This Transportation Statistics Annual Report (TSAR) is the twelfth such report prepared in response to this congressional mandate, laid out in 49 U.S.C. 111 (1). In addition to presenting the state of transportation statistics, the report focuses on transportation indicators related to 13 topics specified in the Safe, Accountability, Flexible, Efficient Transportation Equity Act: A Legacy for Users.
The BTS publication, National Transportation Statistics (NTS), a companion to this annual report, has more comprehensive and longer time series data than could be accommodated here. NTS is available online at www.bts.gov.
