Applications now open for the 2023 Tribal Transportation Safety Assessment (TTSA) Program

October 27, 2022

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.
