About the research

This research aims to develop a uniform, consistent approach that can be applied to estimate the safety performance of rural intersections and road segments at the aggregate (i.e., total crash) level, as well as within specific crash types and crash severity categories. The study results will provide important guidance for the Michigan Department of Transportation (DOT) and local road agencies to make informed decisions as to safety projects.

The Institute for Transporation is a subcontractor to Michigan State University (MSU) on this project.
