摘要
车路协同是智慧交通与自动驾驶融合发展的重要方式,针对自动驾驶功能需求,提出一种面向车路协同的智慧交通路侧系统。设计了一套基于多边接入边缘计算单元、车路协同通信单元、实时动态差分定位基站、融合感知等融合技术的系统架构,通过在既有路灯与标志牌杆件上部署车路通信设备、多传感器融合感知设备、边缘计算单元、高精定位基站等,为车辆提供交叉口车速引导、安全预警、高精地图服务,实际应用证明该系统可有效提升通行效率、行车安全。
Cooperative vehicle infrastructure is an important way for integration of smart transportation and automated driving. To meet the requirements of automated driving, a smart roadside system is designed which based on cooperative vehicle infrastructure system. A system architecture based on multi-access edge computing unit, vehicle infrastructure communication unit, real-time kinematic differential positioning base station, fusion perception and other fusion technologies is designed in this paper. By deploying vehicle infrastructure communication equipment, multi-sensor fusion equipment, edge computing unit and high-precision positioning base station on existing street lamp and sign poles, it can provide speed guidance, safety early warning and high-precision map services for vehicles at intersections, the results show that the system can effectively improving traffic efficiency and driving safety.
