摘要
交通拥堵、交通事故、公共交通不便及空气污染等已成为制约城市交通发展的主要因素,解决城市交通问题已成为智能城市建设的首要任务。利用车路协同技术搭建车辆和信号灯之间的通信通道,及时收集车辆的实时状态、位置信息、道路的拥堵情况和交通流量等信息,通过车辆和道路设施之间的信息交互系统实现自适应的交通信号控制,达到信号灯的精细化控制和智能化管理。基于车路协同的智能信号灯优化控制策略是一种新型的交通信号控制策略,通过实时采集车辆信息、实时监测交通流和调整信号灯,达到交通信号灯优化控制,对全面提高城市交通效率、安全性和环保性,解决城市交通拥堵等问题具有很好的针对性。
Traffic congestion,traffic accidents,inconvenience of public transport and air pollution have become the main factors restricting the development of urban transportation,and solving urban traffic problems has become the primary task of smart city construction.The communication channel between vehicles and signal lights is built by using vehicle-road coordination technology,and the real-time status,location information,road congestion and traffic flow information of vehicles are collected in time.Adaptive traffic signal control is realized through the information interaction system between vehicles and road facilities,so as to achieve fine control and intelligent management of signal lights.The optimal control strategy of intelligent signal lights based on vehicle-road cooperation is a new type of traffic signal control strategy,which achieves the optimal control of traffic lights by collecting vehicle information in real time,monitoring traffic flow and adjusting traffic lights in real time.It has a good pertinence to comprehensively improve urban traffic efficiency,safety and environmental protection,and solve urban traffic congestion.
