Today, the U.S. House of Representatives passed the Fiscal Year (FY) 2023 National Defense Authorization Act (NDAA). Each year, the NDAA authorizes funding levels and provides policy authorizations for the U.S. military and other critical defense priorities. This year, the bill passed by the House also includes a key provision defining transportation demand management (TDM). The FY2023 NDAA includes language defining transportation demand management as “strategies to inform and encourage travelers to maximize the efficiency of a transportation system, leading to improved mobility, reduced congestion, and lower vehicle emissions, including strategies that use planning, programs, policies, marketing, communications, incentives, pricing, data, and technology.” The inclusion of this definition in a “must-pass” piece of legislation is a significant achievement for the TDM community. 


“The inclusion of the TDM definition will go a long way towards educating travelers on different transportation options and ultimately reduce roadway congestion by opening more funding avenues for TDM projects,” said David Straus, Executive Director of the Association for Commuter Transportation (ACT). “On behalf of ACT and the entire TDM community, I want to express our sincere thanks to Representative Marilyn Strickland of Washington for her steadfast support and successful efforts to include the TDM definition language in the NDAA, to all the co-sponsors of this amendment: Representatives Steve Cohen of Tennessee, Madeleine Dean of Pennsylvania, Chrissy Houlahan of Pennsylvania, Joe Neguse of Colorado, with special thanks to Representative Jesus “Chuy” Garcia of Illinois for his persistent and committed assistance in getting this definition passed. Additional thanks to Transportation and Infrastructure (T&I) Committee Chairman Peter DeFazio of Oregon and Armed Services Committee Chairman Adam Smith of Washington and their respective staffs for their coordinated work across two committee jurisdictions. We look forward to working with our Senate partners to ensure this definition is included in the final NDAA legislation that will be taken up and passed by Congress and sent to the President for his signature.”



The Association for Commuter Transportation is the premier organization and leading advocate for commuter transportation and transportation demand management (TDM) professionals. ACT strives to create an efficient multimodal transportation system by empowering the people, places, and organizations working to advance TDM in order to improve the quality of life of all commenters, enhance the livability of communities, and stimulate economic activity.
