1.8 Travel Demand Management (User Service*)
The Travel Demand Management user service uses advanced technologies to support policies and regulations designed to mitigate the environmental and social impacts of traffic congestion. This service generates and communicates management and control strategies that support the implementation of programs to reduce the number of individuals who choose to drive alone; increase the use of high occupancy vehicles and transit; and provide a variety of mobility options for those who wish to travel in a more efficient manner, for example in non-peak periods.
User Service Requirements*:

Travel Demand Management will generate and communicate management and control strategies that will support and facilitate the implementation of TDM programs, policies and regulations. It consists of two major functions, which are, (1) Increase Efficiency of Transportation System and (2) Provide Wide Variety of Mobility Options. |
