Method for determining red-light running of vehicles at intersection based on video detection and signal control system

Abstract

The invention discloses a method for determining red-light running of vehicles at an intersection based on video detection. On the basis of the conventional red-light running capturing system, a group of cameras are added and used for acquiring videos in which the vehicles on an entrance lane of the intersection approach to a stopping line; a vehicle tracking detection area is arranged on a lane which is positioned behind the stopping line of the entrance road of each intersection by a certain distance and used for tracking all vehicles in the vehicle tracking detection area; when a yellow light works, if part of a certain vehicle crosses the stopping line, the yellow light continuously works for one second to make the vehicle completely cross the stopping line before the yellow light stops working; the running state of the vehicles in the detection area is re-determined in one or two seconds before the yellow light stops working; and if a certain vehicle runs a red light and keeps running forward, the turn-on time of a green light in the next phase is delayed in real time, and a red-light running capturing system is started to capture an image of red-light running of the vehicle and obtain evidence.

Description

technical field [0001] The invention relates to the field of traffic signal control, in particular to a method and a signal control system for judging a vehicle running a red light at an intersection based on video detection. Background technique [0002] The main function of the vehicle red light capture system is that the camera automatically records the illegal red light running vehicles at the intersection, which can realize the panoramic video and license plate close-up video of the red light running vehicles under unattended conditions. Provide reliable evidence. [0003] At present, there are mainly two types of products in the domestic market of vehicle red light capture system, according to the triggering methods of illegal vehicle capture, namely ground sensing coil triggering and video virtual coil triggering. The ground induction coil trigger is to cut the circular slot on the detection lane, and then bury the induction coil (or induction rod). When the vehicle...

Problems solved by technology

[0007] The object of the present invention is to provide a video detection-based judging method and a signal control system for running a red light at an intersection, which overcomes the defects of the traditional red light capture system that can only obtain evidence afterwards and cannot judge the behavior of running a red light in advance, and can adjust the traffic signal light accordingly The control scheme achieves the purpose of reducing traffic accidents
