Definition – Transportation Demand Management
(TDM), also called Travel or Traffic Demand Management, aims to reduce the need to travel by discouraging unnecessary private vehicle use and by promoting more effective, healthy and environmentally-friendly modes of transport (generally public transport and non-motorised transport). A TDM strategy typically involves a package of complementary measures that fall within two categories: “push” measures that make private vehicle use less attractive; and “pull” measures that make other modes of transport more attractive.
Relevance to SUMP – Many cities face the problem of congestion meaning the objectives of Transportation Demand Management (TDM) are likely to correspond with the objectives of their SUMP. In these cases, creating measure packages that include both “push” and “pull” effects provides a useful framework for measure selection.
