Lighting Practices for Isolated Rural Intersections

Roadway lighting is a widely recognized intervention for reducing nighttime crashes and isolated rural intersection lighting appears to be beneficial overall, but predicting the benefits likely at a specific location is very difficult.

The TRB National Cooperative Highway Research Program's NCHRP Synthesis 575: Lighting Practices for Isolated Rural Intersections is designed to help provide a foundation for transportation departments considering if, when, and where to install lighting at isolated rural intersections and was carried out to gather information and experiences from different agencies into a single document.
