The invention discloses an intersection area saturation determination method, device and system and a storage medium. The method comprises the following steps: acquiring vehicle trajectory data; grouping the vehicle trajectory data of the target intersection area according to vehicle uuid; traversing the vehicle trajectory data of each group, and determining a driving trajectory corresponding to each group according to the vehicle trajectory data of each group; judging whether the driving track of each group is intersected with the intersection or not; when the driving track of one group intersects with the intersection, adding one on the basis of the current flow counting; and when all groups are traversed, determining the saturation of the intersection area according to the current flow count. By adopting the scheme, the actual traffic condition of the intersection can be objectively reflected.

    本申请公开了一种交叉口区域饱和度确定方法、装置、系统及存储介质,所述方法包括:获取车辆轨迹数据;将目标交叉口区域的车辆轨迹数据按车辆uuid分组;遍历每个分组的车辆轨迹数据,并根据每个分组的车辆轨迹数据确定每个分组对应的行驶轨迹;判断每个分组的行驶轨迹是否与交叉口相交;每当有一个分组的行驶轨迹与交叉口相交时,在当前流量计数的基础上加一;当所有分组遍历完毕时,根据当前流量计数确定交叉口区域的饱和度。采用本方案可以客观地反应了交叉口的实际交通状况。
