Intelligent traffic light control system

Abstract

An intelligent traffic light control system comprises a cloud platform and each traffic node connected to the cloud platform. Each traffic node comprises several vehicle control signal lamps and/or pedestrian control signal lamps. Each traffic node is configured with a communication module. The cloud platform controls indication states of the vehicle control signal lamps and/or the pedestrian control signal lamps through the communication module so as to control allowed passing time. A time control strategy of each traffic node comprises a travelling crane strategy and a pedestrian strategy. Each traffic node is configured with a human body sensor. When the human body sensor detects the pedestrians, the corresponding vehicle control signal lamp and the pedestrian control signal lamp are controlled by the pedestrian strategy; and when the human body sensor does not detect the pedestrians in a certain time, the corresponding vehicle control signal lamp and the pedestrian control signal lamp are controlled by the travelling crane strategy.

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
