双向六车道高速公路自动驾驶专用车道设置

Setting Position of Automatic Driving Lane on Six-lane Expressway

为了分析自动驾驶专用车道在双向六车道高速公路横断面的设置位置,针对3种不同横断面设置形式和自动驾驶集卡编队的编队保持、编队中断2种模式,分析了自动驾驶集卡编队在高速公路全过程运行路径中的出入口、经过互通(枢纽)路段、基本路段等3类典型区域的交通运行状态,发现自动驾驶与普通车辆交织数量X与自动驾驶专用车道经过互通(枢纽)数量N相关:当N=2时,设置在车道3无交织;当N=3时,设置在车道1、3交织数为2;当N>3时,设置在车道1交织数最少。选取京藏高速公路北京市北五环至北六环路段22.5 km作为研究对象,对不同设置形式对交通运行状态的影响进行了分析。结果表明:以minX为目标,自动驾驶专用车道设置位置与N密切相关,当N>3时车道1设置为自动驾驶专用车道为最优方案。

In order to analyze the setting position of automatic driving lanes in the cross-section of dual 3-lanes expressway, the three different cross-sectional settings and the two modes of formation maintenance and formation interruption of the automatic driving truck formation are analyzed. The traffic operation status of three types of typical areas are analyzed, including entrances and exits, passing through(hub) sections, and basic sections of the expressway in the entire operation path. It is found that the interweaving number of automatic driving and ordinary vehicles is related to the number of automatic driving truck-gathering lanes passing through interchange(hub): when, there is no interweaving in lane 3;when, the number of interlaces set in lanes 1 and 3 is 2;When, the number of interlaces in lane 1 is the least. The 22.5 km section from North 5 th Ring Road to North 6 th Ring Road of Beijing-Tibet Expressway is selected as the research object, the influence of different setting forms on traffic operation state is analyzed. The results show that, taking as the target, the setting position of the automatic driving lane is closely related to, and when, it is the best scheme to set lane 1 as the automatic driving lane.
