The invention provides an intersection passage estimation method, computer equipment and a computer readable storage medium, and the method comprises the steps: carrying out the statistics of multi-dimensional driving track data of any intersection in a plurality of sampling time periods; determining a sampling time period to which the current moment belongs so as to generate historical driving and stopping information of the intersection in the sampling time period according to the multi-dimensional driving track data; determining the passing smoothness of each passing direction of the intersection in the sampling time period according to the multi-dimensional driving track data, so as to determine a weight factor corresponding to the historical driving and stopping information in each passing direction according to the passing smoothness; according to the historical driving and stopping information and the corresponding weight factor, estimating the driving and stopping information when the vehicle passes through the intersection. According to the technical scheme, on the one hand, purposeful passage optimization of the intersection is facilitated; on the other hand, the diversity of road condition estimation of the intersection on the navigation map can be improved.
本发明提供了一种路口通行预估方法、计算机设备和计算机可读存储介质,其中,路口通行预估方法包括:统计任一交叉路口多个采样时间段内的多维行驶轨迹数据;确定当前时刻所属的采样时间段,以根据多维行驶轨迹数据生成采样时间段内交叉路口的历史行停信息;根据多维行驶轨迹数据确定采样时间段内交叉路口每一通行方向的通行流畅度,以根据通行流畅度确定在每一通行方向上历史行停信息对应的权重因子;根据历史行停信息与对应的权重因子预估经过交叉路口时的行停信息。根据本发明的技术方案,一方面,有利于对该交叉路口进行有目的的通行优化,另一方面也能够提升导航地图上交叉路口路况预估的多样性。
