Red-Light Running (General)

General Information on Engineering Challenges and Opportunities
This section takes a brief look at the engineering challenges concerning red-light running and the opportunities to engineer solutions that will result in safer intersections with less red-light runners. It provides resources to learn more about the opportunities and tools available to reduce a red-light running problem.

Making Intersections Safer: A Toolbox of Engineering Countermeasures to Reduce Red-Light Running, FHWA/ITE Report 115, 2003. [HTML, PDF 2.47 MB]
Report addresses intersection design and operational features that may need to be upgraded to reduce red-light running. It identifies how various engineering measures can be implemented to address this problem, suggests a procedure for selecting the appropriate engineering measures, and provides guidance on when enforcement, including red-light cameras, may be appropriate.

Field Guide for Inspecting Signalized Intersections to Reduce Red-Light Running, FHWA-SA-05-008, 2005. [HTML, PDF 1.22 MB]
Developed as a supplement to the report above, the Field Guide provides more details on how to conduct a site investigation, including a suggested procedure for conducting an investigation of a specific intersection that has been identified as a red-light running problem site.

Association of Selected Intersection Factors with Red-Light-Running Crashes, FHWA-RD-00-112, May 2000. [PDF 539 KB]
Study examines selected geometric characteristics of intersections, their impact on red-light running crash rates, and potential relationships between them. Examines the effects of the width of the cross-street on crash risk, the relationship of other select intersection characteristics to red-light running crashes, and techniques to apply targeted enforcement techniques such as red-light cameras and/or technology coupled with public outreach.

Red-Light Running Presentation, FHWA, 2008.
This presentation can be used to help raise awareness about red-light running and gain support for a Stop Red-Light Running program or campaign. Both short and long versions of this presentation are available. Topics covered include the nature of the red-light running problem, safety facts and countermeasures.
