Apparatus and method for controlling traffic signals using identification information having hierarchical structure |
摘要 |
Device and method of efficiently controlling a traffic light using identification information having a layered structure are provided. A traffic light control device that controls signal light change of a management-target traffic light includes: a broadcast signal receiving unit that receives a broadcast signal emitted from a traffic control center via a broadcast network, wherein the broadcast signal includes identification information having a layered structure and a control command; and a traffic light control unit that determines whether the management-target traffic light belongs to a target of the control command on the basis of the identification information having a layered structure and that outputs the control signal for performing the signal light change based on the control command only when the management-target traffic light belongs to the target of the control command. |
