Congestion Index Detection System at Traffic Intersections Before Signal Lights

By collecting and processing traffic intersection images in real time, calculating the congestion index and controlling the signal lights, combined with the haze removal processing technology, the problem in the existing technology that the signal lights cannot adapt to traffic conditions and the impact of haze in real time is solved, and the urban traffic efficiency and environment are improved. Protective effect.

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

[0015] The implementation of the congestion index detection system at traffic intersections before signal lights according to the present invention will be described in detail below with reference to the accompanying drawings.

[0016] 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 congestion has become an urban disease,...

Abstract

The invention relates to a traffic congestion index detection system at a traffic intersection in front of a signal light. The control system includes an image acquisition device, an image processing device, a signal light control device and a 3G communication device. The image acquisition device photographs the traffic intersection in front of the signal light to obtain an image of the intersection. , the image processing device performs image processing on the intersection image to obtain the congestion index of each lane at the traffic intersection, the 3G communication device wirelessly sends the congestion index of each lane to the traffic management platform, and receives the feedback signal light control signal, the signal light control device The duration of the traffic light of each sub-light of the signal light is controlled based on the control signal of the signal light. The invention also includes haze removal processing equipment to eliminate the adverse effects of haze weather on images. Through the present invention, even in severe fog and haze weather, the display of signal lights can be controlled according to the actual congestion situation at the traffic intersection, thereby maximizing the use of limited traffic resources.

Description

technical field [0001] The invention relates to the field of traffic signal lamps, in particular to a detection system for congestion index at traffic crossings 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 life a...
