How does commute trip reduction work?
The State Commute Trip Reduction Law affects worksites with 100 or more full-time employees who begin their shift between 6 and 9 a.m. on weekdays in the nine most populous counties in the state. Worksites develop and manage their own programs based on:
- Transportation demand management strategies identified as having the greatest effect for their employees.
- Locally adopted goals for reducing vehicle trips and miles traveled.
Worksites conduct commute trip reduction surveys every other year to measure vehicle miles traveled and the mode choices of their employees. WSDOT and jurisdictions use these survey results to report on collective progress toward drive-alone and vehicle miles traveled reduction targets.
We provide technical assistance to jurisdictions and employers implementing commute trip reduction, lead performance-focused data analytics, develop statewide policies and practices, and support the Transportation Demand Management Technical Committee and Executive Board.
Members of the technical committee fulfill the governance requirements in the State Commute Trip Reduction Law. With direction from the executive board, technical committee members develop policy to support a diverse set of transportation demand management solutions, including updates to WSDOT’s Commute Trip Reduction Program, Mobility on Demand, Mobility as a Service, first-last mile solutions and more. The groups represent diverse perspectives of citizens, businesses, state agencies, transit agencies and jurisdictions around the state.
