This article discusses the use of red light cameras (RLCs) to reduce the incidence of red light running.
Abstract
In 1999, red light running accidents accounted for 92,000 crashes, 90,000 injuries, and nearly 950 deaths. The main solution is the use of automatic red light cameras. They appear to be effective and reliable in reducing the number of traffic signal violations. RLCs detect a vehicle that passes over two sets of wire loops under the pavement after a traffic signal has turned red. These loops are connected to computers in high-speed cameras positioned at the intersection. The camera takes two photographs of the violation, one when the vehicle enters the intersection and the other while it’s in the intersection. Experts review the photographs and citations are mailed to the vehicle’s registered owner. RLCs are currently used in about 70 communities in the United States. RLCs reduce red light running by about 40 percent, and operate constantly without human interference--freeing police resources from traffic detail. RLC enforcement is much safer for police officers, allowing them to avoid pursuing suspects through crowded intersections after running a red light. This enforcement operation doesn’t shut down for inclement weather. RLCs have changed the way drivers behave with regard to red light running. Another advantage is the boost given to police public relations due to strong public support for the cameras. Critics of RLC maintain the principle disadvantage is that communities use the devices for revenue generation rather than for traffic safety. It is suspected that installation of the cameras, coupled with shortening the timing of the yellow light may have more to do with dollar generation than accident prevention. RLCs also inspire concerns about civil liberties. Privacy advocates say they have the potential to erode privacy. RLCs can be used to provide accurate data over time to analyze the progress of intersection safety initiatives.
