The invention discloses an urban road intersection control efficiency evaluation method and a system and a storage medium, and the method comprises the following steps: selecting a target intersectionand an associated entrance, and calculating the traffic saturation characteristic index of a road intersection; calculating an intersection imbalance index based on the saturation characteristic index of the target intersection; weighting the historical maximum value proportion of the intersection saturation characteristic index, and calculating an intersection four-dimensional characteristic index; and calculating the intersection balance degree based on the intersection four-dimensional characteristic index and the intersection imbalance index. According to the invention, indexes are used to reflect the control efficiency of the intersection, the constraints of traffic flow composition and environmental conditions are eliminated, the management efficiency of users for the intersection is improved, and the overall management level is improved. The method can be used for urban road intersection evaluation ranking and intersection optimization reference.

    本发明的一种城市道路交叉口控制效率评价方法、系统及存储介质,包括以下步骤:选取目标路口与相关联入口,计算路段路口交通饱和特征指标;基于目标路口的饱和度特征指标,计算路口失衡指数;加权路口饱和度特征指标历史最大值占比,计算路口四维特征指数;基于路口四维特征指数与路口失衡指数计算路口平衡度。本发明用指标反映交叉口的控制效率,摆脱交通流组成和环境条件的约束,提高用户对于交叉口的管理效率,提升整体管理水平。本发明可用于城市道路交叉口评价排行及交叉口优化参考。
