Transportation Demand Management (TDM)

What is TDM?

Transportation demand management helps people use the transportation system more efficiently through education, incentives, products (like subsidized transit fare cards), and programs that encourage taking transit, carpooling, vanpooling, walking, biking, and teleworking.

TDM activities produce wide-ranging benefits to individuals and the transportation system—saving people time and money and reducing traffic congestion, vehicle emissions, and fuel consumption while supporting physical activity and enhanced safety. TDM activities make existing transportation investments perform better, extend the life of existing infrastructure, and can improve outcomes for new investments.

How can I engage in regional TDM work?

PSRC has had various working groups and committees to engage with stakeholders and regional TDM implementers on regional TDM work. Beginning in 2024, PSRC is no longer convening a formal TDM Advisory Committee. Instead, PSRC is tailoring engagement around the work program with ad-hoc meetings and events. More information will be sent to our list of TDM stakeholders and posted to this page. 

2024 TDM Work Program and Engagement  

 

The first engagement opportunity for 2024 will be Tuesday, April 30, from 10:00 a.m. to 12:00 p.m

Commute Trip Reduction Plans – Local CTR Plans

Jurisdictions affected by the Commute Trip Reduction (CTR) Law are required to develop a local commute trip reduction plan and update it at least once every four years. 

These plans are designed to ensure that CTR program goals and targets help jurisdictions achieve their broader transportation and land use goals, and that the jurisdiction in turn develops services, regulations, policies, and programs that support the trip reduction investments of major employers.

In October 2023 the Washington State Department of Transportation (WSDOT) published guidance for the next cycle of four-year plans, covering July 1, 2025 to June 30, 2029. 

PSRC has compiled the following resources for jurisdictions in King, Kitsap, Pierce, and Snohomish counties developing 2025-2029 CTR plans
