Embodiment Construction

[0028] See figure 1 , the camera 101 is set up above the entrance road of the intersection road and the viewfinder of the camera 101 faces the vehicle entering the entrance road. The virtual detection coil is set above, including the lane detection coil 201, the vehicle passing detection coil 202 and the vehicle presence detection coil 203. The lane detection coil 201 covers the complete guide lane in the real-time video image, and each guide lane in the lane detection coil 201 is along the Vehicle passing detection coils 202 and vehicle presence detection coils 203 are respectively arranged at the front side position and the rear side position of the vehicle traveling direction, and the video detection processing unit 102 detects in real time the traffic flow state of each guide lane in the entrance road and the passing vehicles through the lane detection coil 201. Detecting the headway of vehicles entering each guide lane in the entrance road through the detection coil 202, ...

Abstract

The invention provides a real-time optimization signal control method and system based on video traffic state monitoring. According to the method and the system, the problems of high detecting coil damage rate, inflexible setting and poor data reliability of traditional intersection actuated signal control can be solved. The method comprises steps as follows: a camera is erected above an entrance driveway of an intersection and used for collecting real-time video images of an entrance section of each guide driveway of the entrance driveway; a video detecting and processing unit is used for setting virtual detecting coils on the real-time video images and detecting the traffic state in the entrance driveway through the virtual detecting coils; a logical analysis unit is used for logically analyzing the traffic state in the entrance driveway, and a control adjustment signal is generated according to a logical analysis result and is transmitted to a traffic signal instrument; the traffic signal instrument is used for controlling or adjusting a timing plan of the entrance driveway according to the control adjustment signal.

Description

technical field [0001] The present invention relates to the technical field of road traffic signal control, in particular to the technical field of road traffic signal control based on video detection, in particular to a real-time optimized signal control method and system based on video traffic state monitoring. Background technique [0002] In recent years, in order to solve the increasingly severe traffic congestion problems faced by cities, the construction and application of intelligent transportation systems have been carried out in various places. The role of traffic signal control systems has gradually attracted attention, and it has played a role in alleviating road intersection congestion. However, due to various reasons, road intersections in most cities in my country adopt a single-point, fixed-period, and fixed-time control mode. With the rapid development of urban social economy and the rapid increase in the number of motor vehicles, this control The model has b...
