What is Transportation Demand Management?

Transportation Demand Management (TDM) is moving people, not vehicles, creating a more efficient use of our roadways.  This results in less traffic congestion, better air quality, and even happier, healthier communities.  Products and services include encouragement to use alternatives to the single-occupant (SOV) such as ridesharing (carpools and vanpools), taking transit, riding bikes, and walking.

Alternatives to commuting such as compressed work weeks, flextime, and telecommuting, as well as parking management tactics such as preferential parking for carpools and parking pricing are also effective TDM strategies.

Howard County’s TDM Program is Go Howard, formerly Howard Commuter Solutions, offering assistance to employers, employees, and residents about the many different ways to get to your favorite places.
