Automated systems that record vehicles entering an intersection after the traffic signal has turned red are deployed in specific areas of the city. These devices aim to deter violations and improve safety at potentially hazardous junctions. The photographed evidence, including license plate information, is used to issue citations to the registered vehicle owner.
The implementation of this technology serves to reduce the frequency of collisions resulting from disregard for traffic signals. Historically, intersections equipped with such systems have demonstrated a measurable decrease in angle crashes and other forms of accidents related to signal violations. This technology provides an automated method of enforcement when consistent police presence is not feasible.
