This paper introduces the principle of x2 logic encoder which is based on the combination of emitter photoelectric sensor technology and proximity sensor. Regarding the problem of road snatching in two-direction driving of single lane

an intelligent traffic control device based on Arduino is designed. By collecting data through photoelectric sensor

Arduino executes data processing and logic operation to achieve intelligent control of traffic lights. Its function allows the driver to know in advance whether there is an incoming car. Furthermore

the controlled object is not limit by time control once there is no vehicle passing.
