Transportation Demand Management
Maximizing Travel Choices. Moving People More Efficiently.
Transportation Demand Management (TDM) helps employers, developers, and public agencies reduce congestion, improve mobility, and create more sustainable transportation systems. Our TDM team partners with clients to develop data-driven, people-focused strategies that make it easier to travel without relying solely on single-occupancy vehicles.
With TDM professionals in both the Washington, D.C. metro area and the San Francisco Bay Area, we bring national perspective and local insight to every project.
What is Transportation Demand Management?
Transportation Demand Management is the practice of influencing how, when, and why people travel. Through strategic planning, policy development, mobility programs, and stakeholder engagement, TDM improves transportation system performance while enhancing quality of life.
Effective TDM programs can:
- Reduce traffic congestion
- Increase transit, walking, biking, and carpool use
- Improve commuter experience
- Support sustainability and climate goals
- Lower parking demand and infrastructure costs
- Enhance access, equity, and connectivity
- Help developments meet local transportation requirements
