The Bureau of Transportation Statistics (BTS), a statistical agency within the Research and Innovative Technology Administration (RITA), U.S. Department of Transportation (DOT), compiles, analyzes, and publishes data and information needed for transportation decision making, and generally coordinates DOT statistical programs. BTS also manages the National Transportation Library and the Office of Airline Information, and leads the federal effort in developing transportation geo-data to fulfill the vision of the National Spatial Data Infrastructure (NSDI). |
