The red-light camera system is designed to take two rear photographs of a vehicle that may be committing a violation. The first rear image captures the vehicle prior to entering the intersection with the traffic signal red, and the second image shows the vehicle continuing through the intersection during the red signal phase.
On occasion, a vehicle approaching an intersection with a red light may come to a stop before entering the intersection yet trigger the red-light camera system, causing the flash to discharge. In addition, a vehicle approaching the intersection and making a right turn may not come to a complete stop but only slow before continuing to turn, triggering the red-light camera system and causing the flash to discharge.
The Police Department reviews each violation event captured by the red-light camera system and makes the final decision to issue a citation. All flash incidents do not equate to a citation; however, the imaging results in 80%+ accuracy in identifying excessive speed approaches.
