Transportation demand management is about making it easy for people to use lower cost, higher efficiency transportation options.
What is TDM?
Transportation demand management helps people use the transportation system more efficiently through education, incentives, products, 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.
TDM Advisory Committee
The TDM Advisory Committee promotes a collaborative and coordinated approach to transportation demand management activities happening throughout the Puget Sound region. The Committee provides guidance to local implementers and advises regional policy makers on delivering TDM benefits across the region.
Regional TDM Action Plan
The Regional TDM Action Plan articulates the strategic approach for TDM in the region and recommends actions to support and augment the work happening at the local level. The plan is Appendix F of the Regional Transportation Plan adopted in May 2018.
