高速公路网联车协同匝道汇入多目标优化控制方法和系统,首先采集控制区域车辆的状态数据,随后根据匝道汇入车辆位置决定控制开始的时间与被控车辆的选择,通过数据传输模块将信息传入交通控制模块,基于人工智能的匝道汇入多目标控制模型通过协匝道控制区域内的车辆行驶轨迹,在完成匝道汇入的同时保证道路整体交通高效、安全、节能运行。与传统方法相比,本发明极大地促进了匝道车辆的汇入,并且区别于其他方法将匝道汇入问题转化为车辆排序问题的缺陷,极大的提高了匝道汇入的效率,并且保证主线和匝道的通行效率与通行安全,减少了控制车辆的能耗损失,实现了高速系统经济效益的最大化。

    A connected vehicle coordinated ramp merging multi-objective optimization control method for an expressway, and a system. The method comprises: step 1, collecting state data of vehicles in a control region of an expressway, and analyzing and processing the state data; step 2, according to the state data of the vehicles in the control region, constructing a selectable scheme set for ramp merging vehicles, auxiliary vehicles and guided vehicles; step 3, respectively inputting the selectable scheme set into a ramp merging multi-objective control model based on artificial intelligence, and further determining an auxiliary vehicle and a guided vehicle by means of an optimal value policy; step 4, according to the selected auxiliary vehicle, guided vehicle and merging vehicle, performing acceleration control adjustment on the auxiliary vehicle and the guided vehicle, so as to ensure that the ramp merging vehicle safely merges, in a selected merging region, from an acceleration lane into a main road; and step 5, collecting state data of the ramp merging vehicle and the auxiliary vehicle which have been subjected to acceleration adjustment, and returning to step 4 to perform acceleration adjustment for the next moment.
