Tribal Transportation Safety Assessments (TTSA)

Tribal Transportation Safety Assessment (TTSA) State Planning Research (SPR)

Participants in Happy Camp safety assessment

UC Berkeley SafeTREC conducted Tribal Transportation Safety Assessments (TTSA) for seven (7) California Native American Tribes. The Tribal Transportation Safety Assessment (TTSA) - State Planning Research (SPR) was funded by the California Department of Transportation (Caltrans), Division of Transportation Planning (DOTP), and the Native American Liaison Branch (NALB). The TTSA provided California Native American Tribal Governments with expert, focused, and independent Tribal Transportation Safety Assessments (TTSAs). The goal of the TSSA-SPR project was to reduce injuries and fatalities on all roadways that serve California Native American reservations and Rancherias, as well as roadways accessing their lands, by conducting a TTSA for selected tribal governments.

Each assessment consisted of a two-day site visit, including a public participation meeting and field audit conducted by SafeTREC experts. A technical report, consisting of an analysis and summary of findings and possible suggestions for improvements, and potential sources of funding considered for specific improvements, was submitted to each tribe. 

The technical assistance services and reports provided by this project can help Indian tribes identify potential sources of funding to make the improvements suggested in their reports and can help provide the justifications to use in future grant applications. 

If you have questions about the program, please contact Afsaneh Yavari, TTSA project lead, at safetrec@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 in Action

Read these testimonials from tribal communities that participated in the 2017 Tribal Transportation Safety Assessment (TTSA) program to learn more!

  • The safety assessment report addressed more than we had expected. It has provided us with a framework to help with implementation.
  • We intend on utilizing this plan to obtain funding for implementation of safety measures.
  • We feel that the safety assessment will allow us to address our primary traffic safety issues; the assessment will provide a roadmap which allows us to focus on priority issues that will make transportation planning easier and ultimately more effective.
  • We will develop a tribal transportation safety plan, which will draw a large portion of information from the site safety assessment in 2017.  
  • The safety assessment will be incorporated into our Master Transportation Plan; from there we will seek funding to implement the plan.
