Abstract:Louisiana is among the top crash and fatality overrepresented states with a much higher the national average crash and fatality rates. Traditional approach on high risk crash location identification does not work effectively on locations with low traffic volumes, such as rural and local roadways where bears low design standards. Systemic approach is a proactive way for critical crash location identification based on the roadway geometry and characteristics of locations. Rural two-lane roadways have much higher fatal crash rate than any other roadways. On Louisiana state-maintained rural two-lane roadways, most predominant crash types, “non-collision” single vehicle crashes (79%) on curves are more prevalent than on tangent sections and intersections. By using GIS and logistic regression model, this study investigate relationship between roadway geometric and driver characteristics and crash risk on rural two-lane curves. The analysis results reveal that the key crash contributing factors are alcohol involvement, surface condition, AADT, and radius of the curve.
