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.

    本发明提出一种基于车联网区块链的智能交通灯配时方法,所述交通灯上安装有路测单元,所述方法包括基于区块链实现未身份认证数据安全转发验证阶段和根据城市道路流量感知设计相位轮询交通灯配时模型阶段;所述方法基于区块链身份认证和远程证明保护车辆私人信息并维护数据转发安全,不会因为恶意节点造成交通拥堵及其更严重的后果,同时,该方法提供了非常接近现实交通的车流估计,根据红灯和绿灯下的车流变化规律,探究了整体交通对每条道路及每个交通灯的影响,使用相位轮询模型设计了一种道路交通分析方法,使得路口交通灯合理分配时间,缓解了城市交通拥堵,增加了道路车流速度。
