Method and device for controlling traffic signals of multipurpose electronic police mixed traffic flow detection

Abstract

The invention discloses a method and device for controlling traffic signals of multipurpose electronic police mixed traffic flow detection. The method comprises the steps that traffic operation conditions of a crossing is monitored by a crossing video camera in real time and detected traffic operation condition information is output to an electronic police processor; the received traffic operation condition information is processed by the electronic police processor arranged in the crossing and traffic flow information obtained through processing is transmitted to a traffic signal controller in real time; statistic analysis is conducted on the received traffic flow information by the traffic signal controller and a real-time traffic signal controlling scheme is generated so that traffic signals of the crossing can be controlled. According to the method and device for controlling the traffic signals of multipurpose electronic police mixed traffic flow detection, the instantaneity of traffic signal control can be improved and the traffic signal control efficiency is improved.

Description

technical field [0001] The invention relates to intelligent traffic control technology, in particular to a traffic signal control method and device for multiplexing electronic police mixed traffic flow detection. Background technique [0002] The video surveillance system is an important part of the security system widely used in various industries, and it is also an important part of the intelligent transportation system. With the continuous development of the city, the traffic problems continue to intensify, and the urban road traffic is basically in a saturated state, which makes the city's operation efficiency low and traffic accidents occur frequently. The rapid development of computer, network transmission technology and image processing technology provides the possibility for intelligent control of intersection traffic signals, which makes the scheme of optimizing intersection traffic signal control more and more concerned. Among them, the optimal control scheme of i...

AI Technical Summary

Problems solved by technology

[0005] First, the graphic recognition and processing process in the video detection process is complex

To convert the intersection traffic flow information obtained by video detection into data available to the intersection traffic signal controller, so as to realize traffic signal control, it is necessary to transmit the intersection traffic flow information through remote transmission and output it to the electronic police processor in the network center for corresponding processing. The mutual transmission between multiple modules depends on the intermediate processing module, and the real-time performance of the transmission is poor, which makes the real-time performance of traffic signal control poor

[0006] Second, the traffic flow information obtained by the electronic police processor detection is relatively simple

Generally, there is only flow data, and it is impossible to obtain other richer data that can be used to fully characterize the traffic status of intersections through the analysis of traffic flow information. For example, it is impossible to obtain occupancy data, etc., which makes the effect of traffic signal control poor

[0007] Third, there is a lack of a method for generating a mixed traffic flow adaptive traffic signal control scheme specifically for electronic police processor detection

In the existing solutions, the video detection process and equipment are isolated from the generation process and devices of the intersection traffic signal control scheme. The traffic signal control adopts static configuration and cannot be dynamically adjusted.
