The invention discloses a real-time lane traffic capacity calculation method and system based on Leiyu fusion. The method comprises the following steps: acquiring video image data and radar detection data; performing data fusion on the video image data and the radar detection data to obtain relative space-time information of each vehicle relative to the intersection, and obtaining absolute space-time information of all vehicles at the intersection according to the relative space-time information; traffic timing information and map information of the intersection are obtained, and according to the traffic timing information, the map information and the absolute space-time information, the saturation flow rate of the jth lane in the phase i and the stage green time ratio of the jth lane in the phase i or the passable time ratio of the jth lane in the phase i are obtained; and obtaining the traffic capacity of the jth lane in the phase i according to the saturation flow rate of the jth lane in the phase i and the stage green signal ratio of the jth lane in the phase i.
本申请公开一种基于雷视融合的实时车道通行能力计算方法以及系统。方法包括:获取视频图像数据与雷达探测数据;将所述视频图像数据与所述雷达探测数据进行数据融合,获得每个车辆相对于交叉路口的相对时空信息,并根据所述相对时空信息获得所述交叉路口的所有车辆的绝对时空信息;获取所述交叉路口的交通配时信息与地图信息,并根据所述交通配时信息、所述地图信息以及所述绝对时空信息,获得相位i中第j条车道的饱和流率与相位i中第j条车道的阶段绿信比或者相位i中第j条车道的可通行时间占比;根据所述相位i中第j条车道的饱和流率与所述相位i中第j条车道的阶段绿信比,获得相位i中第j条车道的通行能力。
