2015 Puget Sound Regional Household Travel Survey

The Spring 2015 Household Survey collected day-to-day residential information to determine travel patterns and provide insight for future transportation improvements in Washington State's central Puget Sound region.

The information collected includes how residents traveled, where residents traveled to, and how long it took residents to reach their destinations.

Data Collection Agency

The Puget Sound Regional Council conducted the survey.


This survey was conducted in spring 2015 as a booster survey following the large-scale household (HH) travel and activity survey conducted in 2014. The booster sample of 2,430 HHs included 821 cross-sectional HHs and a panel of 1,609 HHs that participated in the 2014 survey. A subsample of HHs also drawn from the 2014 survey used a smartphone application to collect global positioning system (GPS) paths.
