2017 Puget Sound Regional Travel Study

The 2017 Puget Sound Regional Travel Study collected household- and person-level activity and travel pattern information from residents throughout the Puget Sound Regional Council's four-county region in Washington State.

It followed the 2014-2015 Puget Sound Regional Travel Study, starting a planned six-year data collection that includes 2019 and 2021. The multiyear program's goal is to maintain an updated source of household travel behavior data that:

  • Supports modeling and planning needs
  • Facilitates trend analysis over time
  • Allows for regular study design updates to integrate evolving data collection methods and emerging travel behaviors and transportation issues.

Data Collection Agency

The Puget Sound Regional Council conducted the study.


The 2017 study featured both the design and administration of a one-day household travel diary (approximately 80% of households before data cleaning) and a seven-day smartphone global positioning system (GPS) diary (approximately 20% of households before data cleaning). It combined data collection methods, including smartphone, online, and telephone. The survey design included several stages to recruit and collect data about households, their members, and their travel behaviors during the assigned travel period.

Survey Records

Survey records include a total of 6,254 participants.
