Volume 05: A Guide for Addressing Unsignalized Intersection Collisions
Intersection Crashes–A Large Part of the Problem
Intersections constitute only a small part of the overall highway system, yet intersection-related crashes constitute more than 50 percent of all crashes in urban areas and more than 30 percent in rural areas. Nearly 36 percent of crashes at unsignalized intersections involve injuries and 9 percent involve fatalities.
Improve management of access near unsignalized intersections.
Reduce the frequency and severity of intersection conflicts through geometric design improvements.
Improve sight distance at unsignalized intersections.
Improve availability of gaps in traffic and assist drivers in judging gap sizes at unsignalized intersections.
Improve driver awareness of intersections as viewed from the intersection approach.
Choose appropriate intersection control to minimize crash frequency and severity.
Improve driver compliance with traffic control devices and traffic laws at intersections.
Reduce operating speeds on specific intersection approaches.
Guide motorists more effectively through complex intersections.

Unsignalized Intersection Collisions
Unsignalized intersections pose a special problem for potential collisions because of the priority of traffic flow on the main road, particularly in rural and suburban areas. This guide addresses objectives for reducing collisions in unsignalized intersections, either by improving the intersections and their approaches, or addressing driver compliance.
