Tribal Transportation Safety Assessments

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

Participants in Happy Camp safety assessment

UC Berkeley SafeTREC in collaboration with the National Indian Justice Center (NIJC) has embarked on a new project, Tribal Transportation Safety Assessment (TTSA) - State Planning Research (SPR), funded by the California Department of Transportation (Caltrans), Division of Transportation Planning (DOTP), and the Native American Liaison Branch (NALB). This project will provide California Native American Tribal Governments with expert, focused, and independent Tribal Transportation Safety Assessments (TTSAs). The goal of the TSSA-SPR project is 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 will consist 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, will be submitted to each tribe. 

The technical assistance services and reports provided by this project could also 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. The term of this project is through the end of February, 2021.
