The invention discloses a dynamic lane division method and system for an expressway with ten or more lanes, and the method comprises the steps: arranging a radar detector at a certain section of the expressway with ten or more lanes, and detecting the traffic data, composed of traffic volume and vehicle types, of the section; the controller determines a lane division scheme through a traffic capacity calculation formula according to the real-time traffic data; and the controller guides the display state of the variable information sign board according to the obtained lane division scheme and guides the vehicle to run according to rules. The traffic data of the current road section are obtained through the radar detector, the lane dividing scheme is determined according to the traffic data of the current road section in combination with the traffic capacity calculation sub-formula, the lane dividing scheme is issued through the variable information sign board, and vehicles are guided to run according to rules in real time. From the real-time traffic state, the road traffic capacity can be effectively increased from the lane division angle, the operation efficiency and safety of the expressway are improved, and the method is a powerful supplement for the expressway lane division in China at present.
本发明公开了一种十车道及以上高速公路动态车道划分方法及系统,在十车道及以上高速公路某断面布设雷达检测器,检测断面的由交通量及车型组成的交通数据;控制器依据实时交通数据通过通行能力计算公式确定车道划分方案;控制器根据所得车道划分方案指导可变信息标志板的显示状态,引导车辆按照规则行驶。本发明通过雷达检测器获取当前道路断面的交通数据,根据当前道路断面的交通数据结合通行能力计算分公式确定分车道方案并通过可变信息标志板发布分车道方案,实时引导车辆按照规则行驶。本发明从实时交通状态出发,能够有效的从车道划分角度增加道路通行能力,提高高速公路运营效率和安全性,对目前国内在高速公路车道划分方面是有力的补充。
