US SB3694

Adds a formal definition of "transportation demand management" (TDM) to federal law, covering strategies like carpooling, vanpooling, parking management, telework promotion, and pricing incentives to reduce congestion and improve air quality

Makes TDM projects eligible for funding under multiple federal programs including the Congestion Mitigation and Air Quality Improvement Program, National Infrastructure Project Assistance, and SMART grants

Creates a $20 million annual set-aside for rural TDM grants to fund vanpooling programs, trip-planning apps, traveler information systems, and marketing campaigns in rural communities

Expands the Congestion Relief Program by removing the 1 million population threshold, allowing smaller urban areas to qualify, and creating a $20 million small project set-aside for projects between $500,000 and $10 million

Cites 2024 traffic congestion costs of $74 billion nationally and notes rural households spend more on transportation than urban households due to limited transit options
