Transportation Demand Management for Site Plan Development

Photo: Building constructionTransportation Demand Management for Site Plan Development is an Arlington County Commuter Services (ACCS) program that coordinates the design and implementation of large building projects with commuter and transit infrastructure and services to enhance the mobility of residents, workers, and visitors. Consistent with the vision and mission of ACCS, TDM for Site Plans works directly with developers and property managers to mitigate the transportation impacts of residential and commercial development by increasing the availability, awareness, and use of transit, ridesharing, carsharing, biking, bikesharing, and walking.

Transportation Demand Management, also known as Mobility Management, is the bundle of strategies that influence travel behavior (how, when and where people travel) in order to improve both mobility (that’s people) and system efficiency (that’s money and other resources). Just as our transportation choices influence our personal lives in many ways, demand management is part of the solution to a variety of community-wide challenges. By reducing single-occupant vehicle trips, transportation demand management:

  • Reduces the strain on existing transportation infrastructure, helping it last longer;
  • Reduces the demand for new roads and parking, freeing up resources and space for jobs, housing, parks and other amenities;
  • Maximizes the use of existing public transit services and investments;
  • Supports the economy with increased commute flexibility and increased access to and visibility of local businesses;
  • Improves the environment by reducing emissions of greenhouse gases;
  • Improves public health by reducing emissions of particulate matter and offering transportation options that increase physical activity.

A major strategy to achieve this goal is incorporating important physical infrastructural features, such as bike parking facilities and van-accessible garages, into new or renovated development at the time of construction. Another major strategy is actively monitoring the more than 100 (and counting) site plans to ensure they meet ongoing transportation management program responsibilities. These responsibilities range from promoting participation in carpool and vanpool programs to offering transit subsidies to employees; from managing showers and lockers for bike commuters to distributing brochures about bus routes and schedules, the bikeway system, and other local transportation options.
