• Abstract:
  This report presents results from an analysis of about 47,000 red light violation records collected from 11 intersections in the ; City of Sacramento, California, by red light photo enforcement cameras between May 1999 and June 2003. The goal of this ; analysis is to understand the correlation between red light violations and various driver, intersection, and environmental factors. ; Descriptive statistics suggest that younger drivers under 30 years of age are more likely to run red lights than drivers in other age ; groups. About 56 percent of the violators were traveling at or below the posted speed limit. Moreover, 94 percent of the ; violations occurred within 2 seconds after the onset of red light, and only 3 percent of the violations were recorded 5 seconds ; after the onset of red light. Approximately 4 percent of the violators were repeat offenders. Logistic regression modeling shows ; that the predicted odds of a younger driver running a red light at speeds greater than the speed limit is about 1.5 times the odds of ; a middle-aged driver. In addition, older drivers have a higher probability of running a red light when the elapsed time since the ; onset of red light is more than 2 seconds compared to younger drivers. Finally, red light violations rates are estimated between 6 ; and 29 violations per 100,000 intersection-crossing vehicles.
