The U.S. Department of Transportation's Bureau of Transportation Statistics (BTS), a part of the Research and Innovative Technology Administration (RITA), today released its annual State Transportation Statistics 2011 (STS) – a web-only reference guide to transportation data for the 50 states and the District of Columbia. STS 2011 includes a wide range of state-by-state information, such as the calculations showing which states had the highest and lowest number of highway traffic fatalities per 100,000 population in 2010. The ninth annual STS consists of 115 tables of state data on infrastructure, safety, freight transportation, passenger travel, registered vehicles and vehicle-miles traveled, economy and finance, and energy and environment, plus a U.S. Fast Facts page. STS 2011 can be viewed on the BTS website.
