Apparatus and method for controlling traffic signals

Abstract

Disclosed are an apparatus and a method for controlling traffic signals according to an analyzed result of broadcasting signals transmitted through a broadcasting network. The apparatus for controlling traffic signals which controls the changing of traffic light signals, includes: a broadcasting signal reception unit for receiving the broadcasting signals transmitted from a traffic control center through the broadcasting network; and a traffic light control unit for outputting control signals which determines an offset time for the reference traffic light according to the analyzed result of the broadcasting signals, and controls the conversion of the signals of the controlling target traffic light so as to reconcile a time point delayed as much as the offset time from a signal starting point of the reference traffic light, with a signal starting point of the control target traffic signal lamp. The apparatus for controlling the traffic signals can connect the traffic signals with a correct driving speed of a vehicle by advancing or delaying signals as much as the fixed offset time having the same changing period when one group, including a plurality of related traffic signal controllers, is based on the basis of the reference traffic light.

Description

technical field [0001] The present invention relates to a traffic light control apparatus and method, and more particularly, to an apparatus and method for controlling a traffic light according to an analysis result of a broadcast signal propagated through a broadcast network. Background technique [0002] A traffic light is a device that is installed at a road intersection or a pedestrian crossing and prompts passing vehicles or pedestrians to stop, detour, pass, etc. by flashing red lights, green lights, yellow lights, green light arrows, etc. [0003] Due to the exponential growth of vehicles, traffic congestion has become a serious problem. Vehicle parking time caused by traffic lights at city center intersections or pedestrian crossings accounts for a considerable proportion of the congestion rate caused by various road factors. Therefore, it has been conceived to relieve traffic congestion by controlling the signal cycle of traffic lights at intersections or crosswalk...

AI Technical Summary

Problems solved by technology

[0006] As described above, since only the traffic light controller connected to the traffic control center via a dedicated line performs the signal light change operation on the traffic light to control the traffic flow according to the traffic information based on the traffic condition, while the other traffic light controllers operate with predetermined The signal change cycle of the signal change operation is performed, so there is a problem that the signal lights of all the traffic lights cannot be controlled as a whole, and thus the traffic flow cannot be controlled smoothly

Therefore, there is the problem that traffic lights may work regardless of the traffic flow of other roads
