The invention relates to the technical field of traffic management, and particularly discloses an intersection saturation state detection method and system, computer equipment and a storage medium, and the method comprises the steps: according to the traffic flow, the maximum queuing length and the phase green light time of each lane of a to-be-detected intersection in a target time period, calculating the saturation state of the intersection; respectively calculating the lane level saturation of each lane of the to-be-detected intersection in the target time period; according to the lane driving direction of each lane of the to-be-detected intersection and the lane-level saturation of the to-be-detected intersection in the target time period, calculating the lane-level saturation of the to-be-detected intersection in the target time period; and determining the saturation state of the to-be-detected intersection in the target time period based on the intersection lane level saturation or/and the intersection direction level saturation of the to-be-detected intersection in the target time period. According to the invention, the accuracy and efficiency of intersection saturation state detection can be improved, powerful support is provided for period adjustment of traffic lights, the traffic efficiency of the intersection is further improved, and the traffic conditions of the intersection are improved.
本发明涉及交通管理技术领域,具体公开一种交叉口饱和状态检测方法、系统、计算机设备和存储介质,包括:根据待检测交叉口的每个车道在目标时间段的交通流量、最大排队长度和相位绿灯时间,分别计算待检测交叉口的每个车道在目标时间段的车道级饱和度;根据待检测交叉口的每个车道的车道行驶方向以及在目标时间段的车道级饱和度,计算待检测交叉口在目标时间段的路口车道级饱和度;基于待检测交叉口在目标时间段的路口车道级饱和度或/和路口方向级饱和度,确定待检测交叉口在目标时间段的饱和状态。本发明能够提高交叉口饱和状态检测的准确性与效率,为交通信号灯的周期调整提供有力支撑,进而提高了交叉口的通行效率,并改善了交叉口通行条件。
