The invention relates to a ramp confluence edge cloud management and control method for expressway mixed traffic flow. The method comprises the following steps: collecting mixed traffic flow information in an edge cloud area through a roadside infrastructure, and uploading the mixed traffic flow information to an edge cloud platform; a confluence controller in the edge cloud platform generates all vehicle confluence strategies according to the mixed traffic flow information; the confluence controller performs feasibility analysis on all confluence strategies and performs confluence strategy optimization by taking the sum of passing time losses of all vehicles as an evaluation index; and the confluence controller generates the optimal driving strategy of each vehicle according to the confluence strategy with the minimum loss and distributes the planned optimal track to the intelligent network connection vehicles in the area, and the controlled vehicles perform confluence control according to the collaborative decision result of the edge cloud. Therefore, the problem of mixed traffic flow confluence in the parallel ramp scene of the expressway is effectively solved, the optimal passing time of each vehicle and the optimal overall traffic efficiency can be comprehensively considered, and the real-time performance of the algorithm is good.
本申请涉及了一种面向高速公路混合车流的匝道合流边缘云管控方法,包括以下步骤:通过路侧基础设施采集边缘云区域内的混合车流信息并上传至边缘云平台;边缘云平台中的合流控制器根据混合车流信息生成所有的车辆合流策略;合流控制器对所有合流策略进行可行性分析,并以所有车辆通行时间损耗之和为评价指标进行合流策略优选;合流控制器根据损耗最小的合流策略生成每辆车的最优行驶策略,并将所规划的最优轨迹分发给区域内的智能网联汽车,受控车辆根据边缘云的协同决策结果进行合流控制。由此,有效地解决了高速公路平行式匝道场景中的混合车流合流问题,能综合考虑每台车辆的通行时间最优和交通整体通行效率最优,并且算法的实时性较好。
