• Abstract:
  The objectives of this study were to: a) identify intersections with a high number of crashes involving a driver disregarding the traffic signal, b) identify types of low-cost safety measures which may be used as a countermeasure for red light running, and c) evaluate the effectiveness of the installation of some of these countermeasures at a sample of high-crash intersections. ; Low-cost countermeasures such as double-red signal heads and retro-reflective backplates were installed at locations either identified as a high-crash location or by district traffic engineers. Crashes decreased at these locations with a positive public response. The investigation warrants additional use of the types of low-cost countermeasures evaluated. The type of crash analysis described in the report should be used to identify intersections with intersection characteristics and the specific crash history used to select the specific countermeasure to implement.
