Toolbox of Countermeasures to Reduce Red Light Running

Book Description
Red light running (RLR) is a problem in the US that has resulted in 165,000 injuries and 907 fatalities annually. In Iowa, RLR-related crashes make up 24.5 percent of all crashes and account for 31.7 percent of fatal and major injury crashes at signalized intersections. RLR crashes are a safety concern due to the increased likelihood of injury compared to other types of crashes. The research team developed this toolbox for practitioners to address RLR crashes. The Four Es -- Engineering, Enforcement, Education, and Emergency Response -- should be used together to address RLR problems. However, this toolbox focuses on engineering, enforcement, and education solutions. The toolbox has two major parts: Guidelines to identify problem intersections and the causes of RLR at Intersections and Roadway-based and enforcement countermeasures for RLR.

Book Description
"Red light running has become a serious safety issue at signalized intersections throughout the United States. One objective of this study was to identify the characteristics of red-light-running (RLR) crashes and the drivers involved in those crashes. Driver characteristics, time and day of the crash, occupancy of the vehicle, and environmental factors were tested against any relationship with the RLR crashes and other signalized intersection (non-RLR) crashes. The other objective was to evaluate the effectiveness of retro-reflective signal backplates in reducing red light running as a low cost countermeasure. Crashes that happened in the State of Kansas were analyzed as a case study. Contingency table was used to identify whether a particular factor is related to the crash type, i.e. RLR vs non-ROR. Two methods were used to evaluate the effectiveness of reflective backplates: cross-sectional analysis using an intersection with reflective backplates and an intersection without reflective backplates, and a before-and-after study using four intersections. According to the results of contingency table analysis, the driver age and safety equipment usage, injury severity of the driver, crash severity, time and day of crash, adverse weather conditions, and surface condition were related to crash type. Variables such as gender of the driver, light condition, and presence of passengers were not related to the crash type. The cross-sectional analysis found that reflective backplates are effective in reducing red light violations in the through and left turning traffic flows. The before-and-after study showed a significant reduction in red light violations in one of the two treatments sites, according to paired-t-test statistics. The reduction of red light violations was not significant in the other. Both analysis could not prove a significant impact on red light violations among the right turning vehicles" (page viii).

Book Description
Red light running is one of the major causes of crashes, deaths, and injuries at signalised intersections. The Federal Highway Administration (FHWA) and National Highway Traffic Safety Administration (NHTSA) support a comprehensive approach to intersection safety that incorporates engineering, education, and enforcement countermeasures to prevent red light running and improve intersection safety. Red light cameras can be a very effective countermeasure to prevent red light running. There are a number of studies that indicate reduction in crashes at signalised intersections due to red light cameras. The fundamental objective of the research in this book is to determine the effectiveness of RLC systems in reducing crashes. A description of all project efforts is described in this book.
