What is TDM?
Transportation Demand Management, refers to a variety of relatively low cost activities designed to influence the demand for transportation services. Rather than address the SUPPLY (for example, by building new roads), TDM addresses the DEMAND, by giving people incentives to change their behavior and distribute the demand across hours or days. The purpose of TDM is to maximize the movement of people, not vehicles, within the existing transportation system. TDM activities include carpooling, vanpooling, and work hour management.
