Adaptive traffic light control

At the present time, traffic lights are one of the most used methods to control traffic. However, traffic management is more efficient if data on actual traffic conditions are available to manage traffic signs in real time. This is called adaptive traffic light control.

Sky Light Sensors constantly monitor the traffic flow and transmit information to the traffic light controller via radio through an interface card placed into the traffic controller cabinet.

A controller manages green and red times of the traffic signal according to the actual traffic situation.

Sky Light Intersection System can be used to control a single traffic signal as well as to coordinate multiple systems.
