Transportation Demand Management (TDM) designed to reduce total travel demand, while others are designed to reduce peak period demand, which may disproportionately contribute to these externalities. It is a general term for strategies that result in more efficient use of transportation resources. It refers to a set of strategies aimed at reducing the demand for roadway travel, particularly in single occupancy vehicles. It focuses on helping people use the infrastructure in place for transit, ridesharing, walking, biking, and telework. TDM is a principle that should guide everything we do in designing our transportation and physical infrastructure so that alternatives to driving are naturally encouraged and our systems are better balanced.
