Traffic Detection Cameras
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, a traffic detection camera at the Yonge Street and Yorkville Avenue intersection allow the traffic signal on Yonge Street to remain or “rest in” green until a vehicle is detected by the camera facing 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 traffic detection camera will allow the traffic signal to operate a longer green light for vehicles on Yorkville Avenue.
Traffic detection cameras are not capable of displaying/recording video. Hence, operators at the City’s Traffic Operations Centre are not able to use these cameras for traffic monitoring purposes.
