Regional Household Travel Survey

In 2017 and 2018, the TPB will conduct a survey of 15,000 households in the Washington region and adjacent areas to gather updated information on area-wide travel patterns. TPB has conducted a regional household travel survey approximately every ten years since 1968. The survey, which collects demographic and travel information from a randomly-selected representative sample of households in the TPB region and adjacent areas, is the primary source of observed data used to estimate, calibrate, and validate the regional travel demand model. The model in turn is used for the travel forecasting and air quality conformity analysis of the regional Constrained Long Range Plan (CLRP), and other key program activities. The survey data are also used by staff to analyze regional travel trends, and by TPB member jurisdictions and agencies to conduct their own analysis for their areas of interest. The purpose of the survey is to better understand daily travel and activities in the region: how we travel, where we go, how long it takes us, and what we do when we arrive. The survey seeks to obtain a complete picture of travel patterns in the region. Oversight of the survey program and activities is performed by the TPB Technical Committee and TPB Travel Forecasting Subcommittee.

For more information about the current survey, please visit the Regional Household Travel Survey website at regionaltravelsurvey.com.
