Tribal Transportation Safety Assessment (TTSA)

Needs assessment for the Karuk Tribe (Happy Camp, 2019)

UC Berkeley SafeTREC is inviting 12 California Tribes to apply for the next round of Tribal Transportation Safety Assessments (TTSAs), beginning October 2022 and to be completed by September 30, 2023. TTSA studies will be based on the tribal communities' input about their transportation choices, challenges and opportunities, and can help tribal staff and leadership plan and prioritize safety improvements for all travel modes (walking, bicycling, transit, driving) on tribal roads and pathways, and on roads accessing tribal lands. Tribal staff can also use the TTSA reports in support of their funding applications.

Funded by the California Office of Traffic Safety (OTS), through the National Highway Traffic Safety Administration (NHTSA), TTSAs are FREE to California tribes. 

TTSA engagements include:

  • Collision data analysis by SafeTREC staff
  • Community engagement survey to understand household transportation choices, challenges and opportunities.  (Online and/or printed)
  • With Tribal staff, selection of several focus (study) areas on or near Tribal lands (intersections, corridors, paths, or routes including walk/bike to schools)
  • One-day on-site field visit by a safety expert (walk-audit/drive-about)
  • Detailed illustrated report of findings with analyses, suggestions and concepts

Apply for the 2023 TTSA Program

Applications are now being accepted for the TTSA program! To apply for a TTSA in your community, please complete the application and submit it by Friday, January 20, 2023 to safetrec@berkeley.edu. 

Questions about the TTSA?

For more information about the program, download the TTSA Flyer or contact Afsaneh Yavari, Research & Development Engineer, at afsaneh.yavari@berkeley.edu.

The assessment will provide a roadmap which allows us to focus on priority issues that will make transportation planning easier and ultimately more effective.

The TTSA Program

Since 2015 SafeTREC has conducted 39 transportation safety assessments for California Tribes. The TTSA program is just one of SafeTREC’s free resources for California tribal communities. Others include Tribal Street Story – a map-based “crowdsourcing” tool for gathering community input, and Tribal Transportation Injury Mapping System (TIMS), a map-based crash data search and visualization tool.

Testimonials for the Tribal Road Safety Program

"One of the only Tribes to be selected for this highly competitive grant [California Transportation Commission’s Active Transportation Program (ATP) grant], we were awarded $9.9 million dollars for the Happy Camp Complete Streets Project! The TTSA report was a large part of why our application was successful, and we highly recommend other Tribes to take advantage of the TTSA opportunity while it’s available."
