The invention discloses a green wave control type selection method for a coordinated traffic flow group. The method comprises the following steps: 1) determining a target coordinated traffic flow fO (i-j) between an upstream intersection Ii and a downstream intersection Ij according to an actual coordination demand; 2) determining a coordinated traffic flow group FM (i-j) based on lane setting and phase and phase sequence conditions of a downstream intersection Ij; 3) updating the coordinated traffic flow group FM (i-j) based on the coordinated phase duration of the upstream and downstream intersections and the phase sequence condition of the upstream intersection Ii; and 4) calculating the density aggregation degree of the coordinated traffic flow group FM (i-j) and determining the optimal green wave control type of the target coordinated traffic flow fO (i-j). According to coordination requirements of traffic flows in different flow directions, influences of shared lanes and phase sequences are considered, selection of a target coordination traffic flow and an updating rule of a coordination traffic flow group are given, and the optimal green wave coordination control type of the target coordination traffic flow is selected by calculating the density gathering degree of the coordination traffic flow group under the influence of the distance between upstream and downstream intersections and the flow.
本发明公开了一种面向协调车流组的绿波控制类型选取方法,包括以下步骤:1)根据实际协调需求确定上游交叉口Ii与下游交叉口Ij间的目标协调车流fO(i→j);2)基于下游交叉口Ij的车道设置及相位相序情况确定协调车流组FM(i→j);3)基于上下游交叉口协调相位时长及上游交叉口Ii相位相序情况更新协调车流组FM(i→j);4)计算协调车流组FM(i→j)的密度集聚程度并确定目标协调车流fO(i→j)的最佳绿波控制类型。根据不同流向车流的协调需求,考虑合用车道及相位相序的影响,给出目标协调车流的选取及协调车流组的更新法则,通过计算在上下游交叉口间距和流量影响下协调车流组的密度集聚程度,选取目标协调车流的最佳绿波协调控制类型。
