The National Household Travel Survey (NHTS) provides information to assist transportation planners and others who need comprehensive data on travel and transportation patterns in the United States.
The NHTS dataset contains data for all 150,147 completed households in the sample including household, person, vehicle and daily (travel day) trip level data. In addition to the households selected as part of the national survey this dataset includes the data collected from twenty Add-on program regions.
The 2009 NHTS was conducted under the sponsorship of the FHWA. The Federal Transit Administration, AAA, and the Public Policy Institute of AARP also contributed funding to the national sample of the 2009 NHTS, which included 26,000 households.
Most of the 2009 NHTS interviews were sponsored by the 20 Add-on partners who are state and metropolitan transportation planning organizations that fund additional samples to use as a household travel survey for their respective jurisdictions.
The 2009 NHTS dataset includes all interviews from the national sample and the 20 Add-on partners. The weighting factors have been adjusted to account for the oversampling in the Add-on areas. For example, if New York State was oversampled by a ratio of 4 to 1, then the weights for NY samples were reduced to 1⁄4 of their value. This is an oversimplification of the actual weighting process, but the point here is that the data user can be assured that the weighted data from the NHTS is representative of national estimates. The reason for including all the Add-on samples in the 2009 NHTS database is to allow researchers to use the depth and richness of the additional samples funded by our Add-on partners. Note that any questionnaire items asked only within a particular Add-on jurisdiction are not included in the 2009 NHTS Public Use dataset.
