This is an application of Sollae Systems’ serial to Ethernet module with a traffic signal controller.
A traffic signal controller is used for the proper operation of traffic lights installed on the road. Because the traffic signal controller is run independently, a vast amount of time loss occurs when to change its settings by hand along to the traffic situation.
In this case, drivers will suffer from the changed signal system that may cause a big concern of accidents. To prevent the situation, it is needed for traffic signal controllers controlled from a remote site.
