The invention provides an expressway multi-ramp coordination control method and device and a storage medium, and the method comprises the steps: obtaining the vehicle time sequence data of a target region road section according to the real-time traffic flow data of an expressway, and inputting a target function based on the time sequence data to obtain the error of the total flow of the target region road section and the error change rate; inputting the error of the total flow of the target area road section and the error change rate into a boundary controller of the interval type-2 fuzzy logic, and outputting the total flow of the entrance ramp entering the target area road section; the target area road section is divided into a plurality of sub-area road sections, each sub-area road section comprises at least one entrance ramp, and the weight and the adjustment rate of each sub-area road section are obtained according to the total flow; inputting the weight and the adjustment rate of each sub-region road section into the trained algorithm model, and outputting a corresponding management and control strategy; the management and control strategy comprises each entrance ramp regulation rate and ramp upstream variable speed limit regulation rate in the current time interval.

    本发明提供一种高速公路多匝道协调控制方法、装置及存储介质,根据高速公路实时交通流数据,得到目标区域路段的车辆时间序列数据,基于时间序列数据输入目标函数得到目标区域路段的总流量的误差及误差变化率;将目标区域路段的总流量的误差及误差变化率输入区间二型模糊逻辑的边界控制器,输出入口匝道进入目标区域路段的总流量;将目标区域路段划分为多个子区域路段,每一子区域路段包含至少一个入口匝道,根据总流量获取每一子区域路段的权重和调节率;将每一子区域路段的权重和调节率输入训练后的算法模型,输出对应的管控策略;管控策略包括在当前时间间隔内各个入口匝道调节率和匝道上游可变限速调节率。
