Problems solved by technology

In the existing technology, the traffic management department generally designs a fixed duration of traffic lights for each signal light. Such a design method obviously cannot adapt to real-time traffic conditions. Under the weather, because the image is blurred, the control error is relatively large

Embodiment Construction

[0034] The embodiment of the detection system implementing the method for detecting congestion index at traffic intersections before signal lights according to the present invention will be described in detail below with reference to the accompanying drawings.

[0035] At present, in various countries, especially developing countries, the process of urbanization is constantly being promoted, and the scale of cities is constantly being expanded. Due to the advantages of urban medical care, job opportunities and entertainment, more and more people choose to work or live in the city, which brings about a gradual increase in the number of cars in the urban area. While automobiles bring convenience to people, they also affect the smooth flow of urban traffic. Even in some road sections, due to the oversaturation of cars, the traffic is highly congested, and the time spent driving even exceeds the time people walk, which seriously interferes with people's normal life. Traffic conge...

Abstract

The invention relates to a jamming index detecting method for a traffic intersection before signal lamps. The detecting method comprises the steps that (1) an image collecting device is used for shooting the traffic intersection before the signals lamps, and an intersection image is obtained; (2) an image processing device is used for conducting image processing on the intersection image to obtain the jamming indexes of all lanes of the traffic intersection; (3) a 3G communication device is used for sending the jamming indexes of all the lanes of the traffic intersection to a far end traffic management platform and receiving signal lamp control signals fed back by the traffic management platform; (4) based on the signal lamp control signals, a signal lamp control device used for controlling the red light duration and the green light duration of all auxiliary lamps of the signal lamps. The method further comprises the step of using a haze removing processing device to execute sharpness processing on the intersection image. By means of the jamming index detecting method, the display of the signal lamps can be controlled according to the actual jamming situation at the traffic intersection even under the serious haze weather, and thus the limited traffic resources are used to the maximum.

Description

technical field [0001] The invention relates to the field of traffic signal lamps, in particular to a method for detecting congestion index at traffic intersections in front of signal lamps. Background technique [0002] Due to the excessive concentration of resources in the central area of ​​the city, for example, large hospitals are generally set up in the central area of ​​the city, the administrative departments of the municipal government are also located near the central area, and entertainment venues are set up in the residential area of ​​the urban center, etc., resulting in the concentration of urban residents' travel in urban area. Furthermore, with the improvement of people's living standards, car travel has become a trend. In this way, every time during the peak hours of work, or during weekend entertainment concentration periods, the main road sections in the city are congested. On the one hand, it reduces the efficiency of travel and brings inconvenience to li...
