CRASH REDUCTION DUE TO THE INSTALLATION OF RED LIGHT CAMERAS: GUIDELINES FOR SITE SELECTION. IN: COMPENDIUM: PAPERS ON ADVANCED SURFACE TRANSPORTATION SYSTEMS, 2002

Each year more than one million crashes occur at signalized intersections in the United States. Red light running was cited as the cause of 106,000 crashes, 89,000 injuries and about 1,036 deaths in the United States in the year 2000. In order to address the ever-growing problem of red light violators, some city governments and police departments have turned to automated enforcement. Traditional traffic enforcement requires a police officer to see the violation and then pursue the perpetrator in order to issue a violation. Not only is this costly in terms of deployment, but it is also hazardous for the police officer and the surrounding motorists as the officer may have to speed and run lights in order to catch the violator. The use of automated enforcement technology is a possible solution to the issue of safety and deployment costs. In countries such as the Netherlands and Australia, automated enforcement has decreased the number of red light violators by 35 to 60% and reduced right-angle crashes by 32%. Similar decreases in violations have also been observed in the United States. In New York City, NY, Howard County, MD, and San Francisco, CA the number of violations decreased 20%, 23%, and 40%, respectively. The major issue is whether or not the decrease of red light violators correlates to the reduction in crashes at intersections. From the literature review it can be inferred that red light cameras have an impact on reducing the amount of crashes and injuries at intersections. An e-mail survey was completed to evaluate the criteria utilized for the installation of red light cameras at intersections. Draft guidelines were developed from these criteria and were reviewed by a review committee. Upon the recommendations of the committee the final guidelines were produced. The final guidelines are as follows: (1) Accident history; (2) Red light citation history; (3) Approaching speeds; (4) Traffic and pedestrian volumes; (5) Intersection degree of saturation; and (6) Perceived benefit to cost. Based on these guidelines and the implementation guidelines from previous research, it is the goal that these guidelines be utilized to aid communities in developing countermeasures for red light running and identifying proper locations for the installation of red light cameras should all other countermeasures fail to curtail the red light violations.
