What is the purpose of cameras at signalized intersections?
Jefferson County uses two types of cameras at signalized intersections: detection cameras and traffic monitoring cameras.
Detection Cameras: These cameras use video technology to detect when a vehicle approaches a signalized intersection and are typically mounted on each leg of an intersection. They can be susceptible to false calls when heavy shadows, glare, or snow occur.
Traffic Monitoring Cameras: These cameras are used by traffic staff to monitor traffic patterns or to check on traffic signal operations. These cameras can be watched live by staff during peak travel periods or when an accident occurs.
The county does not store footage from the cameras.
