Transportation demand management (TDM) is the successful complement to infrastructure.

TDM focuses on understanding how people make their transportation decisions and influencing people’s behavior to use existing infrastructure in more efficient ways, like reducing single occupancy vehicle trips and getting people to use transit, ridesharing, walking, biking, and telework. TDM is cost effective in guiding the design of transportation and physical infrastructure so that options other than driving are naturally encouraged and transportation systems are better balanced.
