Apparatus and method for controlling traffic signals using identification information having hierarchical structure
First Claim
1. A traffic light control device that controls signal light change of a management-target traffic light, comprising:
- 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.

Abstract
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.

8. A traffic light control method which is performed by a traffic light control device that controls signal light change of a management-target traffic light, comprising the steps of:
-
receiving 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; analyzing the broadcast signal and extracting layer information of the identification information having a layered structure; extracting distinction data corresponding to the layer information from the identification information of the management-target traffic signal; comparing the distinction data with the identification information of the broadcast signal and determining whether the management-target traffic light belongs to a target of the control command; and performing signal light change based on the control command when it is determined that the management-target traffic light belongs to the target of the control command. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16)
