What is Transportation Demand Management (TDM)?
Transportation Demand Management (TDM) is a term applied to a broad range of strategies that are primarily intended to reduce and reshape demand (use) of the transportation systems. TDM means demand-side strategies (as opposed to supply side strategies such as new lane construction) which are intended to affect how, if, and when the transportation system is used. TDM strategies influence travel behavior by mode, cost, time or route in order to reduce the number of vehicles and to provide mobility options.
