The Bureau of Transportation Statistics (BTS) of the Research and Innovative Technology Administration (RITA) is required by law to report on transportation statistics to the President and Congress. This Transportation Statistics Annual Report is the 15th such report prepared in response to this legislative mandate. In addition to presenting the state of transportation statistics, the report focuses on transportation indicators pertinent to key initiatives of the U.S. Department of Transportation and the topics specified in its mandate.
BTS's National Transportation Statistics (NTS), an online companion publication to this annual report, has more comprehensive and longer time-series data than could be accommodated within this publication. The NTS comprises more than 260 data tables, plus citations for its data sources, a list of acronyms, and a glossary. NTS, which BTS updates quarterly, is available at http://www.bts.gov.
