Tribal Transportation Safety Assessments

For Native American Communities

Based on the successful, award-winning, services funded by the California Office of Traffic Safety (OTS) for Safety Assessments for California Communities, this technical assistance program works similarly to help Native American communities identify and implement context-sensitive transportation safety solutions that will lead to improved safety for all --motorists, passengers, bicyclists, and pedestrians. 

We provide Native American communities with highly focused, in-depth, expert safety reviews of problem areas and specific recommendations for safety improvements within their jurisdictions, as well as on the roadways accessing their land.

The technical assistance services offered by Tech Transfer are intended to provide Tribal governments with a reliable, respected, independent, and credible source of information that fosters collaboration between the Tribes and local engineering, public works, planning or community development, and police/sheriff departments of neighboring agencies.  They also help Tribal governments identify broad information on potential sources of funding to make the improvements, and establish the justification to use in future grant applications. 


About the assessment

The T2SA technical assistance is designed for Tribal Councils or their designees, who have responsibility for the implementation of the potential recommendations for safety improvement.  Each assessment will be conducted by one or two safety experts from Tech Transfer who will conduct the assessment, based on the size and complexity of the assessment area. The expert(s) will visit the Native American community site (e.g., reservation or rancheria area) for one day, including meeting with the Tribal representatives and local and State representatives for the area, and any other stakeholders, as may be appropriate or feasible.  After the site visit, the expert team from Tech Transfer will produce a report highlighting the results of the site visit, the analysis completed for the site, and a list of suggestions for safety improvements, including broad information on potential funding sources of proposed improvements. 


Survey and application for an assessment

We are now working with Federally-recognized Indian Tribes applying for grant funding from the Federal Highway Administration (FHWA) for Tribal Transportation Program Safety Funds (TTPSF).  If you are interested in a safety assessment or partnering on your TTPSF grant application including a safety assessment, please contact us at

To help us better understand your specific tribal transportation safety issues and needs, and to serve as an initial exploration for a safety assessment, please complete the online survey below as soon as possible:
