TDM for Local Governments

Successful TDM programs start at the local level with neighborhood design and parking decisions. Efficient land use and streets designed for all users can reduce the need for auto travel for daily trips. Managing parking supply and pricing can encourage alternatives to single occupant vehicle travel.

The adoption and implementation of a comprehensive set of TDM strategies by local governments promotes sustainable mobility and supports smart growth land use decisions. These strategies can be incorporated into a variety of municipal plans and policies.

Where have municipal TDM strategies worked?

San Diego, CA. The Circulation Element of the City of San Diego’s General Plan dedicates a section to TDM policies. Inclusion of TDM in the General Plan has led to implementation of a successful on-street, all-electric carshare program.

Charlotte, NC. The award-winning Urban Street Design Guidelines created a process for designing complete streets where the needs of all users and various land uses are considered. This process, along with design guidance, is applied to capital projects and helps transform a multitude of urban and suburban streets.

Ventura, CA. The City’s Parking Management Program uses pricing to ensure a 15 percent parking vacancy rate for premium on-street parking. This discourages long-term street parking so that customers who go downtown have access to the business(es) they visit. To reduce the amount of new parking needed, this program also offers shared on-site parking between land uses that have different periods of peak parking demand.

Cambridge, MA. The Parking and Transportation Demand Management Ordinance requires employers to provide amenities or incentives that encourage employees to use alternative modes of transportation. In 2011, this ordinance contributed to a 24 percent decrease in vehicles miles traveled (VMT) which equated to a reduction of 38 million vehicle miles.

Arlington, VA. The Transportation Demand Management for Site Plan Development Program works directly with developers and property managers to mitigate the transportation impacts of development by increasing the availability, awareness, and use of alternative modes. Mixed-use development is encouraged along commuter rail service, allowing for rapid growth without major highway or parking expansion.
