2001 National Household Travel Survey – Wisconsin Add-On
The Wisconsin add-on survey supplements the 2001 National Household Travel Survey (NHTS) with additional household samples and detailed travel behavior for an assigned travel day.
Data Collection Agency
The Federal Highway Administration and Wisconsin Department of Transportation conducted the survey.
The NHTS ran from March 2001 through May 2002, with data collection for the Wisconsin add-on occurring May 1, 2001 to May 6, 2002. The NHTS collected data on the demographic and socioeconomic composition of households, as well as detailed information on travel behavior nationwide.
State transportation departments and metropolitan planning agencies had the opportunity to purchase extra household samples as part of the NHTS add-on program. These additional samples, along with national samples collected in the add-on areas, are compiled for use in transportation planning, forecasting, and research. The Wisconsin Department of Transportation participated in the NHTS add-on program and received a total of 17,610 household samples in Wisconsin. (The total number of household samples nationwide is 26,038.)
Survey records include 40,560 participants.
The NHTS Wisconsin add-on data package contains a demographic and socioeconomic composition of 17,610 household samples in Wisconsin, as well as detailed information on the travel behavior of each household for an assigned day. It does not contain data pertaining to residence type (i.e., single family home, apartment, condo, etc.). For details on available data and variable definitions, see the data dictionary.
