When we drive our car on the road or walk through the pavement, there are always cameras found on traffic signal lights in certain areas of the city are used to detect traffic patterns. The timing of the traffic signals can then be adjusted to best meet traffic flow in that area.
Cameras are located at intersections that include East Johnson Street and Country Lane, East Johnson Street and Prairie Road, and Scott and Main streets. These are the most recent cameras to be installed on the new solar power traffic light , Skiff said.
At some intersections there is a cabinet (box) that controls the signals with a camera located inside. It’s different technology but functions the same way, he said.
“These are used to see what traffic is coming and to adjust the timing of the lights accordingly,” Skiff said.
The cameras in the LED arrow lights are simply cameras, he pointed out, and do not contain the hardware required for recording.
Skiff said the cameras are for troubleshooting.
Many intersections in the city also have loop detectors, an electrical conduit in the pavement that contains a sensor to read traffic. The goal is to have good traffic flow along the main streets of the city.
The traffic signal lights are set for a maximum 60 seconds for main streets and about 40 seconds for side streets, he said. There are 46 traffic signals throughout the city.
