APAARATUS AND SYSTEM FOR TRAFFIC SIGNAL CONTROLLING AND METHOD THEREOF

摘要

An apparatus and a system for controlling a traffic signal are provided to improve efficiency of traffic control by controlling a traffic signal display by transmitting and receiving the information about the travel quantity. A traffic signal control device includes a signal display unit(210), a traffic sensor(220), a wireless transceiver(230), a signal controller(240). The signal display unit displays the traffic signal for controlling the road traffic. The traffic sensor senses the travel quantity of the vehicles passing through and entering a first area around the signal display unit. The wireless transceiver transmits the information about the travel quantity of the vehicle passing through the first area and receives the information about the travel quantity of the vehicles passing through the second area around the other signal display unit adjacent to the first area. The signal control unit controls the traffic signal display of the signal display unit based on the sensed travel quantity of the vehicles entering the first area and the received travel quantity of the vehicles passing through the second area.
