The invention provides a road condition information obtaining method and device and a server, and belongs to the technical field of navigation. The method comprises the following steps: determining afirst driving path; acquiring road condition information of at least two road sections included in the first driving path; starting from the last road section of the first driving path, performing reverse path traversal in the first driving path, and determining at least one second driving path; determining road condition information of the starting road section according to the comprehensive flowdirection road condition information of the starting road section of the second driving path and the shunt direction road condition information of the starting road section to the terminal road section of the second driving path; and determining the road condition information of the first driving path according to the road condition information. Starting from the last road section of the first driving path, reverse path traversal is carried out in the first driving path, and at least one second driving path is determined; the road condition information of the first driving path can be determined without constructing a route table and querying the route table, so that the efficiency of acquiring the road condition information is improved.

    本申请提供了一种路况信息的获取方法、装置及服务器,属于导航技术领域。该方法包括:确定第一行驶路径;第一行驶路径中包括的至少两条路段,获取路段的路况信息;从第一行驶路径的最后一个路段开始,在第一行驶路径中进行反向路径遍历,确定至少一个第二行驶路径;根据第二行驶路径的起点路段的综合流向路况信息和起始路段向第二行驶路径的终点路段的分流向路况信息,确定起点路段的路况信息;根据路况信息,确定第一行驶路径的路况信息。由于从第一行驶路径的最后一个路段开始,在第一行驶路径中进行反向路径遍历,确定至少一个第二行驶路径;不用构建路线表和查询路线表,就确定第一行驶路径的路况信息,提高了获取路况信息的效率。
