Preface

Congress requires the Bureau of Transportation Statistics (BTS) to report on transportation statistics to the President and Congress. Transportation Statistics Annual Report 2001 (TSAR) is the eighth such report prepared in response to this congressional mandate, laid out in 49 U.S.C. 111 (j). The report discusses the extent and condition of the transportation system; its use, performance, security, and safety record; transportation's economic contributions and costs; and its energy and environmental impacts. All modes of transportation are covered in the report.

The BTS publication, National Transportation Statistics (NTS), a companion to this annual report, has more comprehensive and longer time series, tabulated data than could be accommodated here. NTS is available both in print and online at www.bts.gov.
