Our mission

Meeting calendar icon and link

The mission of the TDM Technical Committee and TDM Executive Board is to improve the quality of life for all Washingtonians by shaping and determining policies that support successful, innovative TDM programs statewide. The purpose of the committee and board is to influence broad TDM goals and targets; inform policy; and elevate the profile TDM can play in advancing collective outcomes around public health, economic vitality, climate change, and supporting thriving communities.

Both groups also support WSDOT’s strategic plan, specifically its inclusion and Practical Solutions goal areas, as well as the Governor’s Results Washington initiative. The board is supported by a 16-member technical committee that will take input from the board to develop TDM program recommendations.

TDM outcomes are diverse, but include better travel-time reliability, cleaner air and water, GHG emission reductions, vibrant and well-connected communities, and access to opportunity for all.

All technical committee meetings are open to the public, and meeting calendars, materials, notes and slides will be made available here.

Transportation demand management action plan

In December 2019, the TDM Technical Committee and TDM Executive Board developed consent on adopting a revised 2 year Transportation Demand Management (TDM) Action Plan. The plan establishes TDM priorities through June 2021.

The plan aims to leverage the TDM Executive Board’s influence and standing, and the TDM Technical Committee’s expertise and hands-on experience to:

  1. Ensure that improvements to existing TDM programs (such as CTR) meet stakeholder needs.
  2. Develop new, effective TDM strategies grounded in stakeholder input and expertise.
  3. Build statewide, multi-sector support for the implementation of TDM strategies.
