摘要
在车路协同环境下设计自动驾驶专用车道入口区域交安设施和传感通信控制设施布置方案,解决入口交织区产生的交通瓶颈问题。首先,提出了自动驾驶专用车道定义。其次,将自动驾驶专用车道起点区域划分为警告区、上游过渡区和缓冲区。分析了自动驾驶专用车道入口2个交织区的构型、长度、宽度及其交通运行特性、车辆获取信息需求,设计了自动驾驶专用车道入口区域交安设施和传感通信控制设施的布置方案,总结了技术要求。最后,利用本方法设计了杭绍甬高速自动驾驶专用车道入口区域交安设施和传感通信控制设施的布置方案。本研究对自动驾驶专用车道入口区域设计、建设及关键设备研发等提供技术支撑,对示范建设自动驾驶专用车道具有参考意义。
In the environment of vehicle-infrastructure collaboration,the layout scheme of traffic safety facilities and sensor communication control facilities in the entrance area of automatic driving special lane is designed to solve the traffic bottleneck problem caused by the entrance interweaving area.First,the definition of automatic driving special lane is proposed.Second,the starting point area of automatic driving special lane is divided into warning zone,upstream transition zone and buffer zone.The configuration,length and width of 2 interweaving areas at the entrance of the automatic driving special lane,and the traffic operation characteristics and the demand for vehicle information are analyzed.The layout scheme of traffic safety facilities and sensor communication control facilities in the entrance area of automatic driving special lane is designed,and the technical requirements are summarized.Finally,the layout scheme of traffic safety facilities and sensor communication control facilities in the entrance area of the automatic driving special lane of Hangzhou-Shaoxing-Ningbo Expressway is designed by using this method.This research provides a technical support for the design and construction and key technologies R&D of the entrance area of the autonomous driving special lane,and provides a guidance and reference for the demonstration and construction of the automatic driving special lane.
