MnDOT installs new traffic signal detection cameras along Hwy 15 in Fairmont

MANKATO, Minn. – With Highway 15 construction nearing completion, motorists in Fairmont can see new traffic detection cameras mounted on traffic signals throughout the corridor.
The cameras are used to tell the new traffic signals when vehicles are present and to ensure the correct amount of green time is provided to vehicles approaching the intersection.  Pointed at the pavement, the cameras sense when there is an object within their view and send a message to the traffic signal.

The cameras are not used for traffic law enforcement, in accordance with state law. The low-resolution cameras are not able to record or store images of drivers or license plates, and the images are not able to be viewed remotely.

The cameras are a cost-effective alternative to the traditional traffic signal detection sensors installed within pavement. Detection cameras are currently being utilized in other areas of south central Minnesota, including Waseca, Saint Peter and Mankato.
