This paper presents an evaluation of the use of lighted pavement markers in parallel to an intersection stop bar for a single intersection approachin Houston, Texas. The line of pavement markers is active with a red light (light emitting diode) displayed from each marker during the red interval of the traffic signal. The intended impact of the pavement markers wasto reduce red light running violations and crashes on the intersection approach to an arterial with an at-grade light rail line within the median of the street. A before and after study was conducted to determine changesin crashes, red light running violations, and right turn on red violations. From the analysis results, it was determined that the lighted pavementmarkers appeared to reduce right turn on red violations. Furthermore, red light running violations were slightly reduced, but the change was not statistically significant.
