Preface

Congress requires the Bureau of Transportation Statistics (BTS) to report on transportation statistics to the President and Congress. This Transportation Statistics Annual Report (TSAR) is the tenth such report prepared in response to this congressional mandate, laid out in 49 U.S.C. 111 (j). In addition to presenting the state of transportation statistics, the report focuses on transportation indicators related to 15 topics. Most of these topics were specified in the Intermodal Surface Transportation Efficiency Act; one was added by the Transportation Equity Act for the 21st Century.

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 both in print and online at www.bts.gov.
