What is Transportation Demand Management?

Transportation Demand Management (TDM) is the study of travel behavior within an organization or region, and the implementation of strategies to encourage more efficient and sustainable travel habits. TDM improves quality of life in communities by reducing the number of single occupancy vehicles (SOV) on the roadways.

A TDM plan may be required by state or local governments, or an organization may choose to implement TDM strategies as a cost-effective way to achieve sustainability goals and increase employee satisfaction.

TDM strategies may include providing information to employees about transit options, designing individualized trip plans, offering benefits or incentives for alternative transportation choices, and supporting existing transit infrastructure with shuttle services.
