Easy-to-implement traffic signal lamp adaptive method

Abstract

The invention discloses an easy-to-implement traffic signal lamp adaptive method, and belongs to the technical field of traffic safety. The method comprises the following steps: S1, initializing a system; S2, collecting traffic flow data; S3, distributing the duration of each traffic light at the intersection; S4, carrying out road condition judgment; and S5, controlling a traffic light system. The low-power-consumption single-chip microcomputer, the wireless communication module and the camera are installed on the traffic light, the duration of all green lights at the intersection can be adjusted in a self-adaptive mode according to the traffic flow, the traffic light can be automatically turned off under specific conditions, the traffic condition is improved, meanwhile, the traffic light is more reasonably used, the traffic light or the road does not need to be constructed and reformed in the whole installation process, implementation is easy, and cost is low; the camera is combined with an image processing program to measure traffic flow data so that the traffic flow data can be accurately measured; and the traffic lights are communicated through the wireless communication module, and the requirement for the distance between the traffic lights is not high.

Description

technical field [0001] The invention belongs to the technical field of traffic safety, and in particular relates to an easy-to-implement adaptive method for traffic signal lights. Background technique [0002] With the popularization of private cars, road traffic pressure is increasing, traffic accidents occur frequently, and traffic congestion is even more unavoidable. In severe cases, a large number of traffic policemen are even required to dredge manually. The traffic light system is an important tool to control traffic flow and reduce traffic accidents. , which has received extensive attention and research from researchers. [0003] Researcher Kong Zhiqi built a traffic light time setting model and analyzed the model using actual traffic data. The above research only focuses on the ratio of red light to green light time, and optimizes the traffic system by finding the best ratio. However, this red light. A traffic light system with a fixed time ratio of green lights can...

Problems solved by technology

[0005] (1) It is difficult to implement, especially in the underground inductance coil to detect traffic flow, which means that the entire road needs to be modified;

[0006] (2) Only considering improving traffic flow and vehicle emissions by optimizing the traffic system, but not taking into account that traffic lights themselves consume a lot of energy;

[0009] 22) At some intersections, there are a lot of cars coming from all sides during the rush hour. If traffic lights are not used to control the passage of vehicles at this time, traffic accidents are extremely likely to occur. The presence of lights causes the vehicle to stop and start frequently, which not only easily affects the driver's driving mood, but also brings more vehicle emissions. This situation is named as no traffic light intersection when there is no congestion
