What are the different types of traffic signals? I’ve noticed cameras on some of them.

Castle Rock uses two types of traffic signals: fixed-time signals and traffic-actuated signals. Fixed-time signals are set for average conditions and change at predetermined time intervals. Traffic-actuated signals use video cameras or radars. Each detection type has pros and cons, but they all detect the presence of vehicles at an intersection and adjust the timing for optimal traffic flow.

In the past few years, the Town has made improvements to our traffic signal system by installing CCTV cameras at traffic signals to improve our understanding of situational awareness and be able to make signal timing adjustments and improve maintenance of signal operations.
