Red light camera
Red Light Camera
A Red Light Camera (RLC) is a type of traffic enforcement camera that captures an image of a vehicle which has entered an intersection in spite of the traffic signal indicating red (during the red phase). By automatically photographing vehicles that run red lights, the photo is evidence that assists authorities in their enforcement of traffic laws.
Operation[edit | edit source]
Generally, the camera is triggered when a vehicle enters the intersection (passes the stop-bar) after the traffic signal has turned red. Typically, a law enforcement official will review the photographic evidence and determine whether a violation occurred. A citation is then usually mailed to the owner of the vehicle found to be in violation of the law.
Effectiveness[edit | edit source]
Studies have shown mixed results as to the effectiveness of red light cameras. Some studies found that the devices decreased the total number of all crashes, while others found that they increased the total number.
Criticism[edit | edit source]
Critics of the red light camera system argue that the cameras do not improve safety, and may actually cause more rear-end collisions due to drivers stopping abruptly to avoid being photographed by the system.
