Surveying Your Employees

Multimodal transportation options

State law requires CTR-affected worksites to measure employee commute behavior to determine their progress toward CTR goals. To help worksites meet this requirement, WSDOT provides the forms you need to conduct your survey, a process for analyzing your data, and technical assistance along the way.

Jurisdictions have different approaches to surveying. If you are a worksite representative (e.g., employee transportation coordinator), please work with your jurisdiction representative to determine the best process for surveying your employees.
