Commute Trip Reduction - Employee Surveys

State law requires some employers to periodically measure employee commute behavior at certain worksites. To help jurisdictions survey local employers, WSDOT provides the forms needed to conduct surveys, a process for analyzing the data, and technical assistance along the way. Jurisdictions have several different approaches to surveying. If you are a worksite representative (e.g., employee transportation coordinator or ETC), please work directly with your jurisdiction representative to determine the best process for surveying your employees.

    Policy updates

    The TDM Technical Committee approved changes to the 2021-22 commute trip reduction survey cycle at their September 2020 meeting.
