2001 National Household Travel Survey

The U.S. Department of Transportation recently released data from the 2001 National Household Travel Survey (NHTS), the nation's inventory of daily and long-distance travel. The survey includes demographic characteristics of households, people, vehicles, and detailed information on daily and longer-distance travel for all purposes by all modes. NHTS survey data are collected from a sample of U.S. households and expanded to provide national estimates of trips and miles by travel mode, trip purpose, and a host of household attributes.

The 2001 NHTS data can be used to investigate topics in transportation safety, congestion, mobility of various population groups, the relationship of personal travel to economic productivity, the impact of travel on the human and natural environment, and other important subjects. These data provide planners and decision makers with up-to-date information to assist them with effectively improving the mobility, safety, and security of our nation's transportation systems. Trends and changes in travel behavior can be identified and understood by analyzing the data series, which for daily travel now encompasses more than 30 years.
