The National Household Travel Survey, last conducted in 2001, is a U.S. Department of
Transportation effort sponsored by the Research and Innovative Technology Administration’s Bureau of Transportation Statistics and the Federal Highway Administration to collect data on both long-distance and local travel by the American public. The survey gathers trip-related data such as mode of transportation, duration, distance, and purpose of trip. It also gathers demographic, geographic, and economic data for analysis purposes. U.S. residents on average travel about 14,500 miles each year on daily trips, more than half way around the world.
