This controller is used to control traffic lights in single-lane, two-way scenarios. Once connected to the Dual Loop Detector, the controller can collect and analyze traffic flow data, and control the operational state of the traffic lights to provide directions for vehicles.

The primary application of this traffic signal is for single-lane, two-way roads. Through the traffic light indicator and Dual Loop Detector, it aims to provide traffic directions for vehicles. This effectively prevents the phenomenon of opposing vehicles getting stuck in traffic on single lanes.
