Abstract

The invention provides a traffic light regulation and control device and method based on big data, and the method comprises the steps: triggering a traffic congestion state, and obtaining a traffic congestion type; generating a traffic light switching instruction, wherein the traffic light switching instruction comprises a target phase identifier and a target phase duration; and sending the signal lamp switching instruction to a signal machine corresponding to the traffic signal lamp to indicate the signal machine to switch the phase of the traffic signal lamp to the target phase in the next time window. According to the invention, the traffic signal lamps are regulated and controlled by triggering the traffic congestion state, the traffic road condition of the road intersection can be monitored in real time by collecting a plurality of data, and the traffic signal lamps are adjusted in real time according to the current traffic road condition, so that the road congestion caused by vehicle overstock is avoided, and the driving efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of traffic management, in particular to a traffic light control device and method based on big data. Background technique [0002] As an important part of urban construction, urban traffic has an important impact on people's lives. It penetrates into all aspects of our lives, especially related to our travel. Traffic congestion is a direct manifestation of the imbalance between supply and demand of the road within a certain period of time. When traffic congestion occurs, the traffic flow in the upstream and downstream of the road will change significantly. In the upstream section, traffic capacity decreases, traffic density increases, road occupancy increases, driving speed decreases, traffic flow through the road section decreases, vehicle delay increases, and travel time to the destination increases. [0003] The rapid increase of automobiles has also brought a huge load to urban road traffic. ...
