Unsignalized Intersections

Technical Implementation & Tools

  • NCHRP Report 500: Volume 05: A Guide for Addressing Unsignalized Intersection Collisions [HTML, PDF 1.41 MB]
    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.

  • NEW Proven Safety Countermeasures
    Corridor Access Management is featured as one of the nine Proven Safety Countermeasures that are the subject of the 2012 Guidance Memorandum on Promoting the Implementation of Proven Safety Countermeasures.
