Description

TMAs/TDM Organizations are typically non-profit, member-controlled organizations that are fundamentally public-private partnerships, bringing together businesses, local government, and sometimes residents and other organizations to manage transportation demand within a specific area. Providing an area-wide basis for TDM planning improves messaging, communications, and efficacy of TDM implementation in the broader community. A TMA can both assist employers and conduct community-based planning customizing mobility education and outreach for specific groups to promote non-driving options like transit, biking, and walking.

Implementation Details

  • Develop customized travel education campaigns with employers, school districts, senior centers, and local nonprofits.
  • Distribute multilingual travel planning toolkits that promote awareness of Marin Transit, carpools, walking routes, and active modes.
  • Use community engagement (tabling, intercept surveys, online feedback) to identify barriers and tailor programs to specific neighborhoods or events.
  • Focus efforts where car ownership rates are lower.
  • Implement Mobility as a Service (MaaS) systems and other technology to make trip planning more convenient.

Mitigation Potential

TDM programming provides residents and employees with tailored information, incentives, and support to encourage walking, biking, transit use, and carpooling.

Linked Strategies

Equity Considerations

Equity-focused travel planning should be tailored to the specific needs of each community, using multilingual materials, culturally relevant outreach, and partnerships with trusted local organizations. Strategies should prioritize low-income neighborhoods, rural communities, and historically underserved groups by offering personalized mobility support, including route planning, transit training, and bicycle education.

Funding Sources

Requires staff time from a regional organization to help coordinate the development and implementation of a TMA/TMO. One funding source is the Sustainable Transportation Planning Grant Program – Sustainable Communities – Competitive and Technical (Caltrans).

Implemented in TAM Area

Current TDM Implementation

TAM functions as the transportation and travel demand management organization in Marin.

TDM Benefit Locations

To supplement TAMs work, more localized TMAs and TDM organizations can tailor solutions at the jurisdiction level.
