The San Diego Association of Governments (SANDAG) has partnered with the County of San Diego to develop two workshops for County staff on best practices for implementing TDM policy through the development process. The workshops are based off of a guidebook that SANDAG developed for local jurisdictions in 2012: Integrating TDM into the Planning and Development Process – A Reference for Cities. The interactive workshops are intended to increase awareness of the benefits of TDM for the County and will serve as a forum to glean feedback on the opportunities for incorporating TDM into the greenfield development review process. The workshop materials will be made available online and adapted for other interested jurisdictions. Transportation Demand Management (TDM) refers to programs and strategies that manage and reduce traffic congestion by encouraging the use of transportation alternatives. Typical TDM programs reduce single occupant vehicle (SOV) trips through ridesharing initiatives such as carpooling and vanpooling; alternative work schedules and teleworking; and the promotion of transit, biking, and walking to work. However, TDM strategies should not be limited to just commute trips. TDM strategies, programs, and plans are most effective when considered for all trips and at all geographic levels - from a specific site, to a neighborhood, city, and regional or state levels – creating a comprehensive and coordinated approach. Local governments play a critical role in TDM planning and implementation. Land use, urban design, and parking policies are all under the jurisdiction of local governments and are essential in influencing travel choice and demand. Efficient land use and urban design can reduce the need for auto travel for daily trips, and appropriate parking supply and pricing can encourage the use of alternative modes of transportation. Local jurisdictions are in a unique position to implement a broad range of TDM strategies at many different points in the development process. While the state and region can enact legislation and set broad policies, local governments have the ability to guide the implementation of TDM strategies through the planning process using short and long-range plans, and can implement TDM strategies through development agreements, zoning, policies, and ordinances.
