Transportation Demand Management

From Wikipedia, the free encyclopedia

Transportation Demand Management or "TDM" is changing or reducing demand for car use by encouraging the behavioural change of household choices of travel. TDM is used increasingly by urban planners to affect the rate at which new development attracts cars and increases the need for new or expanded roadways.

Examples of TDM measures include the following.

  • Requiring users of parking to pay the costs of it directly, as opposed to sharing the costs indirectly with others through increased rents, tax subsidies, etc.
  • Including and improving transit infrastructure, such as subway entrances, bus stops, etc.
  • Subsidizing transit costs for employees or residents
  • Bicycle-friendly facilities, including secure bike storage areas and showers
