摘要： A method of encoding a continuous path within a road network is described, the path being completely represented within a digital map and expressible as a path list of lines and/or segments existing in said digital map and consecutively ordered, wherein said lines and/or segments have one or more attributes associated therewith. The method involves storing a start position in a route search list, and determining a path from the start node of the start position and including said start position to an end node of the last line or segment in the path list within said digital map. The path is determined according to an algorithm utilizing an attribute of said lines or segments. The attribute may be a lowest functional road class (LFRC) of the path to be encoded or a part thereof.

摘要翻译：描述了在道路网络内对连续路径进行编码的方法，该路径被完全表示在数字地图内并且可表示为存在于所述数字地图中并连续排列的线和/或段的路径列表，其中所述线和/或段具有与其相关联的一个或多个属性。该方法包括将开始位置存储在路径搜索列表中，以及从起始位置的开始节点确定包括所述开始位置的路径到所述数字地图中的路径列表中的最后一行或段的结束节点。根据利用所述线或段的属性的算法来确定路径。该属性可以是要编码的路径的最低功能道路等级（LFRC）或其一部分。
