The present invention relates to an integrated intersection management system, and more particularly, to an integrated intersection management system capable of identifying a signal violation vehicle and an accident vehicle by integrally managing an intersection, and identifying a signal violation degree and an accident path.

Today, automobiles are becoming as important as modern necessities for modern people, but due to the improper driving habits of drivers, traffic order is not well maintained, and traffic accidents have resulted in many casualties and property damages.

In particular, the traffic accidents between cars during the above-mentioned traffic accidents occur frequently at intersections where many vehicles are crowded, and traffic accidents in which pedestrians are injured by cars occur frequently at crossings. In violation of the law.

In other words, if the traffic lights turn yellow or red at intersections or crossings, the vehicle must stop at the stop line, and the driver ignores it and causes excessive traffic while driving.

Most drivers keep a good signal while the traffic officer is checking and ignores the traffic signal when they leave. Because of the shortage of traffic policemen, no traffic officers can be placed at all intersections or crossings. As a result, the damage caused by daily traffic accidents is left to no help.

As a countermeasure, a camera is installed on the road to capture a car passing through the road, and then a car is automatically detected to violate the traffic signal. However, the camera is to photograph all cars driving on the road. Therefore, when there is a vehicle that violates the signal, the film is not enough to shoot.

In addition, while regularly replaying the video recorded on the film of the camera to detect a signal violation vehicle, the situation is not properly utilized due to the lack of traffic police officers who have the time to do so.

In other words, the damage caused by traffic accidents is gradually increasing according to the increasing number of cars, but there is a problem that there is no system for automatically detecting cars that violate traffic signals.

As a result, a system for monitoring signal violation vehicles has been proposed for the purpose of monitoring intersections and detecting signal violation vehicles, for example, as disclosed in Korean Utility Model Model No. 1999-011258 (published date: March 25, 1999). As such, a "signal violation auto detection system" has been disclosed.

The prior art relates to a system for detecting and identifying a vehicle that violates an instruction provided by traffic lights of various traffic facilities, and detects a vehicle that is located in front of a vehicle stop line in a driving direction and detects a signal by a microcomputer. Vehicle detecting means for outputting; A signal light controller for electronically controlling red, yellow, and green lights of a traffic light, and outputting a control signal to the microcomputer when a red light or a yellow light is turned on; A microcomputer for outputting a photographing control signal to a camera when a sensing signal of the vehicle detecting means and a control signal of the traffic light control unit are input at the same time, and transmitting a photographing video signal input from the camera to a central traffic control center through a modem; When a photographing control signal is input from the micom, the vehicle may be photographed in violation of a traffic signal, and the camera may be configured to output the photographed video signal to the micom. It can be used in traffic facilities equipped with traffic lights and stop lines, such as crossings and crosswalks, so that the vehicle driver can automatically detect and identify violations of the traffic lights of the corresponding traffic facilities.

However, the above-described prior art can detect a signal violation vehicle, but there is a structural problem in that it is not possible to detect an accident vehicle or an accident vehicle occurring at an intersection, and also cannot determine an accident situation.

The present invention has been made to solve the above problems, the object of the present invention is to detect the signal violation vehicle and accident vehicle for the vehicle traveling at the intersection, intersection integration that can grasp the accident history of the accident vehicle To provide a management system.
