Preface

The Bureau of Transportation Statistics (BTS) of the Research and Innovative Technology Administration (RITA) has a legislative mandate to report transportation
statistics. This Transportation Statistics Annual Report is the 16th such report prepared in response to this requirement. The report focuses on transportation indicators pertinent to key initiatives of the U.S. Department of Transportation and the topics specified in this mandate. In addition, BTS highlights efforts to improve transportation statistics.

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. 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/publications/national_transportation_statistics/.
