Transportation Demand Management Defined

Transportation demand management (TDM) is a set of strategies and polices aimed at reducing travel demand and congestion by reducing the use of single occupancy vehicles by using the existing transportation system more efficiently. This means encouraging and enabling people to carpool, vanpool, walk, bike, take transit, or telework.

 By using these other transportation modes, we’ll create more livable communities, save money, improve our health and the environment, and mitigate traffic congestion.

TDM underlies many important issues of today like social justice, transit-oriented development, complete streets, walkable activity centers, and livability and sustainability initiatives to name a few.

TDM’s priorities

TDM’s priorities as established in the IU TDM plan are to:

  • Establish strong administrative stance to reduce drive alone commuting to campus
  • Elevate status of walking, biking, and carpooling to equal status as drive alone mode
  • Build awareness to capitalize on existing programs and build momentum for alternative transportation use
  • Provide financial incentives for alternative mode use (paid for by financial disincentives for drive alone commuting)
  • Provide additional TDM programs and supportive infrastructure improvements
