The Bureau of Transportation Statistics (BTS), a part of DOT's Research and Innovative Technology Administration (RITA), presents State Transportation Statistics 2007, a statistical profile of transportation in the 50 states and the District of Columbia. This is the fifth annual edition of the State Transportation Statistics, and a companion document to the National Transportation Statistics (NTS), which is updated quarterly on the BTS website. Like the previous editions, this document presents transportation information from RITA/BTS, other federal government agencies, and other national sources. A picture of the states' transportation infrastructure, freight movement and passenger travel, system safety, vehicles, transportation related economy and finance, and energy usage and the environment is presented in tables covering the 50 states and the District of Columbia. Tables have been updated with the most recent data available. Included in this State Transportation Statistics 2007 report is a brief description of the data sources used and a glossary of terms. Also contained in this publication is a summary table that displays the approximate timing of future data releases and contact information for each state's department of transportation.
