Traffic detection cameras detect the presence of vehicles and allow traffic signals to respond to changes in the traffic volumes by varying the length of green lights.

For example, cameras at the Yonge Street and Yorkville Ave intersection allow the traffic signal on Yonge Street to remain or “rest in” green until a vehicle is detected by the cameras on Yorkville Avenue. If only one or two vehicles are waiting on Yorkville Avenue, the camera will cause the traffic signal to operate a short green light.

At busier times of the day, the camera will allow the traffic signal to operate a longer green light for vehicles on Yorkville Avenue. The vehicle detection cameras are not recording information and the City does not have the ability to watch traffic at this time.
