Transportation Demand Management and Chevy Chase Lake
Transportation Demand Management (TDM) programs encourage more efficient use of transportation systems, reducing demand for road expansion and parking, therefore, affecting land use and design of new developments. There are numerous TDM strategies to influence travel decisions. Some improve the transportation options available; some provide incentives to change travel mode, time or destination; others improve land use accessibility; some involve transportation policy reforms and new programs that provide a foundation for TDM. Typical TDM Programs consist of education, marketing, outreach to employers and residents as well as advocacy for alternative commuting options. By reducing total vehicle traffic and improving overall accessibility, TDM provides multiple benefits, including congestion reduction, road and parking savings, transportation options (choices), road safety, environmental protection, improved quality of life, economic development and healthy lifestyles.
Typical TDM measures include:
- Transit and vanpool subsidies
- Pre-tax deduction of transit and vanpool fares
- Telework program
- Carpool and vanpool matching service
- Shower and locker facilities for bicyclists and walkers (office only)
- Secure and weatherproof bicycle parking
- Carpool and vanpool preferential parking
- On-site car sharing vehicle
- Employee shuttle
- Guaranteed Ride Home Program
- Commuter information center (bulletin board, website, brochure table)
- Employee Transportation Coordinator (ETC)
- Flexible or alternative work hours
- TDM education programs directed at the public and employers
- Parking controls/management programs
Literature consistently points to financial incentives and disincentives as most effective in changing travel behavior. Financial incentives include mode subsidies (i.e. tax favored transit discounts or vanpool fare subsidies), parking cash-out, discounted parking for alternative mode users, and indirect financial incentives (i.e. programs awarding points toward rewards for trips and alternative modes). Parking fees, particularly those set at market rate, are the primary disincentive. Programs employing financial incentives/disincentives exhibit trip reduction rates several times those of programs without these strategies. These measures are most effective if combined with the design of new developments that make it easy for residents and employees to walk, bike, take public transit safely to nearby retail, office and entertainment centers. Mixed use developments in close proximity of transit stations with robust TDM programs have proven to be the most effective way to reduce single occupancy vehicles. TDM today is considered one of the most important components of Smart Growth.
TDM is one of several components being considered for the redevelopment of Chevy Chase Lake to mitigate traffic challenges. The Chevy Chase Land Company already performs some of these functions, such as an employee shuttle that we make available to the public. We are also taking the lead on promoting and funding a county bikeshare program. We anticipate incorporating TDM into any plan that may be developed.
