The invention discloses a channel area boundary control method for trunk line green wave control. The method comprises the following steps: step 1, establishing a green wave band model for a target trunk line; step 2, establishing a trunk line association degree model for describing the association degree of the road section and the trunk line in the channel area; 3, based on a target trunk line-oriented channel region division algorithm, obtaining a trunk line-oriented channel region; and step 4, establishing a trunk-line-oriented channel region boundary control model and method based on a reinforcement learning technology. Compared with the prior art, the method has the positive effects that the boundary intersection of the channel region is dynamically managed and controlled through macro and micro combination, the overall number of vehicles in the controlled region is stable macroscopically, and the traffic flow distribution in the controlled region is reasonable microcosmically, so that the traffic condition of the trunk line is optimized and improved; negative indexes such as trunk traffic delay and parking times are reduced, and normal operation of traffic in a channel area can be guaranteed.
本发明公开了一种面向干线绿波控制的通道区域边界控制方法,包括如下步骤:步骤一、对目标干线建立绿波带模型;步骤二、建立用于描述通道区域路段与干线关联程度的干线关联度模型;步骤三、基于面向目标干线的通道区域划分算法,获取面向干线的通道区域;步骤四、基于强化学习技术建立面向干线的通道区域边界控制模型与方法。与现有技术相比,本发明的积极效果是:本发明通过宏微观结合,动态管控通道区域边界交叉口:宏观上把控区域整体车辆数稳定,微观上把控区域内部车流分布合理,从而不仅优化改善干线交通状况,减少干线交通延误与停车次数等负面指标,而且可以兼顾保障通道区域交通的正常运行。
