Travel Demand Management:
An Introduction
Two ApproachesTwo ApproachesTwo ApproachesTwo Approaches
Supply-oriented: predict need, supply infrastructure to meet travel demand
Demand-oriented: influence the need to, timing of, and location of travel to reduce overall demand and make existing supply more efficient

DEFINITION: What is DEFINITION: What is Travel Demand Management?Travel Demand Management?DEFINITION: What is DEFINITION: What is Travel Demand Management?Travel Demand Management?
The U.S. Department of Transportation, Federal Highway Administration defines TDM:
Managing travel demand is about providing travelers, regardless of whether they drive alone, with travel choices, such as work location, route, time of travel and mode. In the broadest sense, “demand management is defined as providing travelers with effective choices to improve travel reliability.”
Federal Highway Administration, 2006

Any strategy, program, or combination of strategies and programs designed to change travel habits. Specifically, TDM projects attempt to reduce single occupant vehicle trips. (Greenfield, Massachusetts)
The general term for strategies that result in more efficient use of transportation resources. (Burlington, Vermont)

TDM vs. Mobility ManagementTDM vs. Mobility ManagementTDM vs. Mobility ManagementTDM vs. Mobility Management
Transportation Demand Management (TDM) tends to include a broad set of strategies that includes road pricing, facilities to encourage mode shift, and incentives to use them
Mobility Management (MM) may be seen as a subset of TDM which includes measures such as information, marketing, partnerships, communications, and promotion of sustainable modes. “MM is soft measures to influence travel before it starts.”

Final ThoughtsFinal ThoughtsFinal ThoughtsFinal Thoughts
TDM is not a cure-all; one tool in toolbox
TDM involves packages of strategies designed to influence travel and travelers
Individual strategies have finite impacts
TDM most effective when integrated
TDM is widely acknowledged as low-cost when compared to supply-side solutions
TDM is becoming more of a philosophy than a set of strategies
