Intersection Safety Camera Technology

Why Intersection Cameras Work

Intersection Safety Cameras capture, on film, drivers who violate red lights and speed through intersections. They reduce the amount of red light running that occurs in the City of Winnipeg. Additionally, they are an effective tool for reducing speed at intersections, and thereby reduce the severity of injuries in the case of a collision.

Signs for traffic light photo 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 entrances to the City to remind motorists that intersections may be photo enforced.  Intersection Safety Camera locations are published so everyone knows where they are installed

When am I in Violation?

Violations occur when:

  • A vehicle behind the stop line when the light turns red proceeds through the intersection, ignoring the red light
  • Drivers do not stop before turning right on a red light

People waiting to turn left or caught in the intersection by traffic backlog would not be photographed, as they are not red light runners

How the Intersection Safety Camera Works 

The intersection safety camera is usually located about 20 meters back from the intersection. This is to allow the photographs to be taken of the rear of the vehicle that is violating the red light. 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
