An Intelligent Traffic Light Control System

Abstract

A smart traffic light control system, comprising a cloud platform and each traffic node connected to the cloud platform, each traffic node comprising a plurality of vehicle control signal lights and / or pedestrian control signal lights, the traffic node being equipped with a communication module, the cloud platform controlling the indication state of the vehicle control signal lights and / or pedestrian control signal lights by means of the communication module in order to control the allowable passage time, and the time control policy of each traffic node comprising a vehicle policy and a pedestrian policy; the traffic node is provided with a body sensor, and when the body sensor detects a pedestrian, the corresponding vehicle control signal light and pedestrian control signal light are controlled by the pedestrian policy; and when the body sensor has not detected a body for a certain period of time, the corresponding vehicle control signal light and pedestrian control signal light are controlled by the vehicle policy.

Description

technical field [0001] The invention relates to a traffic light control system, in particular to an intelligent traffic light control system. Background technique [0002] At present, the traffic light control methods used in China are mainly divided into timing distribution method, induction control method and monitoring room control method. [0003] The timing distribution method refers to the control of traffic signals according to the preset timing scheme, also known as cycle control. The equipment required by the timing distribution method is simple, the investment is the least, and the maintenance is convenient. It is a widely used basic control method and is suitable for traffic conditions where the traffic flow changes relatively regularly. However, it lacks flexibility. For example, it is easy to accumulate vehicles in a phase with many vehicles, which will cause traffic jams at the next intersection. When there is no vehicle in a certain phase during the passing t...

AI Technical Summary

Problems solved by technology

The control mode of the monitoring room has high flexibility, but manual intervention is required and the workload is heavy

Therefore, the use cost of the monitoring room control method is relatively large

[0006] Regardless of the above-mentioned control methods, it is through manual intervention to a large extent, and cannot intelligently solve the problem of pedestrian number detection and realize the switch between pedestrian traffic and traffic traffic
