• Abstract:
  Red Light Running (RLR) has become an increasely national safety issue at signalized intersections. ; Significant efforts have been made to understand the RLR related driver behaviors and develop ; countermeasures to reduce RLR and its related crashes. At high speed intersections, it has been well ; shown that drivers caught in dilemma zone is an important reason of RLR. While at arterial intersections, ; there are still needs to further investigate RLR related driver behaviors. We carried out our research at ; a well-designed arterial intersection (speed limit 35 mph to 30 mph, approach dependent) and collected ; data using multiple discrete point sensors at different distances-to-intersection from multiple approaches. ; Empirical data showed that for over 90% of the RLRs, the drivers were not trapped in dilemma zone at ; yellow onset. Instead, they could have stopped safely and comfortably. Further analysis of the empirical ; data showed that over 60% of the RLR were with a headway less than 3 seconds, or belonged to a platoon. ; The average headway of RLR vehicles were 10% less than that of vehicles going through yellow. The ; findings were used in the development of an all-red interval extension system for intersection collision ; avoidance.
