The tribal RSA case studies project sponsored by the FHWA Office of Safety has been well received by the participating tribal transportation agencies. The case studies project has exposed tribal governments to the concepts and practices of an RSA, and provided the opportunity for tribal staff members to participate on the RSA team as part of the process. This case studies document has summarized the results of each RSA, with the intent of providing tribal governments with examples and advice to assist them in implementing RSAs in their own jurisdictions.
