摘要
随着我国社会经济水平和城市化进程的不断加快,城市道路拥堵问题日益凸显严重。车路协同技术作为智能交通系统的核心发展方向,可融合物联网、云计算、5G通信等新一代先进信息技术手段,实现人、车、路、环境等要素的一体化和谐发展。本文通过对车路协同系统架构和技术特点的分析,以及对车载单元、路侧单元、交通信息发布与控制等技术的探索,提出了城市道路与高速公路两个场景下的具体应用,可有效提高交叉口车辆通行能力与高速公路服务水平。
The social economy development and the urbanization acceleration result in the congestion problems in city.The car road collaboration technology,as the core of the intelligent transportation system development direction,can combine IoT,cloud computing,5G communication etc,to realize the harmonious development of integration of pedestrian,vehicle and road elements.Based on analyzing the characteristics of car road collaboration system and technology and the detailed introduction of car unit,road unit,traffic information release and control technology,the specific application in two scenarios of intersection urban road and expressway is proposed respectively,which can effectively improve the capacity of vehicles at the intersection and expressway service level to some extent.
