A method, system, device and storage medium for area control based on signal lights

Abstract

The present application relates to an area control method based on signal lights, which includes the following steps: obtaining the traffic flow information of each lane connected to the current intersection; calculating the ratio of the traffic flow of the lane corresponding to the current traffic light to the traffic flow of another crossing lane; According to the obtained ratio, the ratio of the countdown duration of the green light and the red light corresponding to the current traffic light is calculated through the preset ratio calculation formula, and the ratio of the countdown duration of the green light and the red light increases when the obtained ratio corresponding to the traffic flow within the set range increases; Obtain and calculate the red light countdown time based on the preset current green light countdown time, record and store the green light countdown time and red light countdown time; output the corresponding green light countdown time and red light countdown time control in the next cycle of the red light and green light cycle Signal. The application has the effect of relieving congestion to reduce traffic pressure.

Description

technical field [0001] The present application relates to the field of signal lamps, and in particular to a signal lamp-based area control method, system, device and storage medium. Background technique [0002] Road traffic signal lights are a category of traffic safety products. They are an important tool to strengthen road traffic management, reduce traffic accidents, improve road use efficiency, and improve traffic conditions. [0003] Road traffic lights include traffic lights, which are mostly set at crossroads or T-junctions. The rules of traffic lights are relatively simple. Generally, the countdown time of red lights and green lights is fixed. For example, the green light runs alternately for 60 seconds and the red light runs for 30 seconds. Ease of vehicle transition. [0004] Some urban road sections will adopt the method of adjusting traffic lights according to peak hours or road conditions. For example, the traffic lights of some road sections will be set to pr...

Problems solved by technology

[0005] In view of the related technologies mentioned above, the inventor believes that there are the following defects: in actual situations, crossroads or T-junctions of different road sections often present different traffic flow conditions at different periods, such as the traffic flow of a certain lane during non-peak hours. During skyrocketing, the green light time in the direction of this lane may be too short, resulting in the abnormal phenomenon that another lane is idle and the vehicles on this lane are congested, thus affecting the normal operation of traffic
