National Household Travel Survey, 2001: [United States] (ICPSR 4047)

Principal Investigator(s):


The 2001 National Household Travel Survey is a combination of the Federal Highway Administration's Nationwide Personal Transportation Survey (NPTS) and the Bureau of Transportation Statistics American Travel Survey (ATS), which were conducted separately in previous years. The National Household Travel Survey serves as the nation's inventory of daily personal travel. It collects data on daily trips including purpose of the trip, means of transportation used, travel time, vehicle occupancy, driver characteristics, and vehicle attributes. These data are collected for all personal trips, all modes and purposes, all trip lengths, and all areas of the country, urban and rural. The 2001 National Household Travel Survey collected additional data on trips to a destination 50 miles or more from home (long-distance travel) that started from home and ended at home during a four-week travel period. This was a change from previous years, where the travel range was 75 miles or more. Part 1, the Household File, contains data unique to a household, such as the number of household vehicles, household income, the relationship between household members, demographic information for household members, and educational level of the household respondent. Part 2, the Person File, contains demographic information, driver status, information on travel to work, miles driven, customer satisfaction, and Internet use. Part 3, the Vehicle File, contains data relating to each of the household's vehicles, including annualized vehicle miles. Part 4, the Travel Day Trip File, contains data about each trip the person made on the household's randomly assigned travel day. Parts 5 and 6 are weight files for the Household File (Part 1) and the Person File (Part 2), respectively.
