Summary

The systemic approach is particularly apt for specific crash types that occur less regularly or in areas where crashes are more widespread, as opposed to clustered. The systemic approach uses site characteristics to evaluate risk despite limited crash numbers. This is especially applicable for Kentucky’s Local Road Safety Plan (LRSP) program due to the lack of sites with a history of severe crashes. As one example, Boone County’s LRSP sought to reduce deaths and serious injuries within the county by recognizing and prioritizing roadway safety improvements through the systemic approach.
