Intelligent traffic light timing method based on Internet of Vehicles blockchain

Abstract

The invention provides an intelligent traffic light timing method based on an Internet of Vehicles blockchain. A drive test unit is installed on a traffic light, and the method comprises a stage of realizing secure forwarding verification of unauthenticated data based on the blockchain and a stage of designing a phase polling traffic light timing model according to urban road flow perception. Themethod is based on blockchain identity authentication and remote certification to protect vehicle private information and maintain data forwarding security. Traffic jam and more serious consequences caused by malicious nodes are avoided; meanwhile, the method provides traffic flow estimation which is very close to real traffic. According to the traffic flow change rule under the red light and thegreen light, the influence of overall traffic on each road and each traffic light is explored, and a road traffic analysis method is designed by using a phase polling model, so that the intersection traffic lights reasonably distribute time, urban traffic congestion is relieved, and the road traffic flow speed is increased.

Description

technical field [0001] The invention relates to the technical field of communication and traffic control, in particular to an intelligent traffic light timing method based on the Internet of Vehicles block chain. Background technique [0002] At this stage, traffic information security and traffic congestion have become urgent problems to be solved. In increasingly complex traffic conditions, the false information of malicious vehicles will bring immeasurable losses to traffic, and at the same time, unreasonable planning will also lead to increased traffic congestion. If a scheme that takes into account data transmission security and traffic light timing can be designed, it will protect private information of vehicles and eliminate false data of malicious vehicles to reduce traffic congestion. [0003] The blockchain in the current V2V and V2I is overused, and the scope and method of using the blockchain are not clear. Traffic light timing is mostly modeled on the basis of...
