The third annual analysis of red-light safety cameras (photo enforcement) by the New Jersey Department of Transportation (NJDOT) has found overall decreases in crashes, as well as decreases in the number of annual citations issued, for all program years.

A traffic control signal monitoring system—i.e., a Red Light Running (RLR) system—is an integrated device utilizing one or more cameras and sensors that work in conjunction with a traffic control signal to produce images of vehicles that disregard a red signal. These images are transmitted to law enforcement officials who review both still photos and video produced by the system to determine if a violation has in fact occurred.
