The objectives of this project were to (a) review and assess states’ current practices for quantifying serious injuries from motor vehicle crashes, (b) describe issues to be addressed in adapting CODES or other available databases to provide a basis for comparative analysis of DOT performance regarding serious crash injuries and safety management, and (c) describe feasible options for addressing these issues and assess their relative merits. Research is complete, and the final report is available for download on the TRB website.
