How intersection safety cameras work
Intersection Safety Cameras capture, through digital imaging, drivers who violate red lights and speed through intersections. The goal is to reduce the amount of red light running that occurs on Winnipeg streets, and they are also an effective tool for reducing the speeds of vehicles in these intersections.
Signs for intersection safety camera enforcement are posted at every intersection where an intersection safety camera is installed, informing motorists that cameras are in use at these locations. Signs are located at major entrances into Winnipeg to remind motorists that intersections may be photo enforced.
The intersection safety camera is usually located about 20 metres back from the intersection. This allows photographs to be taken of the rear of the vehicle that is violating the red light or travelling at a high rate of speed. The camera is connected to the traffic signal control box and to two sensors buried in the roadway. One sensor is installed near the stop line, and the second sensor is about two meters back from the first.
When the light turns red, the sensors become active. A vehicle traveling over the sensor triggers the camera unit and two photographs are taken.
- The first picture is of the vehicle outside the intersection during the red phase. The picture shows that the traffic light is red.
- The second picture shows the vehicle actually in the intersection and must show that the light is still red for an offence to have been committed.
Violations occur when:
- a vehicle behind the stop line when the light turns red proceeds through the intersection.
- drivers fail to stop before turning right on a red light.
- drivers exceed the posted speed limit
