Communities evolve alongside changes in resident and worker demographics, new developments, and the growth of transportation options. For example, the desire for green, open spaces has grown alongside walkable neighborhoods where people can live, work, and enjoy activities using a variety of multimodal transportation facilities and services. As the built environment changes, so does the travel patterns and quality of life of the community. For example, providing information on available travel options beyond driving alone and building complementary infrastructure to support these types of travel modes, help create a community whose transportation policy is to move people, not cars.

As transportation options increase and evolve, so does the need to make transportation easy for those who commute or simply want to go from point A to point B. Transportation Demand Management (TDM) creates better travel experiences for everyone by providing a variety of choices to maximize use of the existing transportation network. Through partnerships and engagements with residents, the business community, and visitors, TDM helps shape a community who makes more efficient use of public transit and transportation infrastructure that are already in place.

TDM helps meet the changing needs for mobility by providing transportation options beyond driving alone. TDM lends its transportation expertise and complimentary assistance to several touchpoints in the business, residential, and commercial building communities. For example, in Arlington County, people who live, work or visit Arlington are provided with programs and services that are designed to encourage the use of public transit, carpooling and vanpooling, bicycling, walking, teleworking – options other than driving alone. As a result, these programs help reduce the number of drive-alone trips and have an impact on parking congestion and air quality.
