STS 2014 includes a wide range of state-by-state information. The 12th 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.
