Abstract: A technique for updating road maps is disclosed. A number of GPS traces can be matched with a number of roads in a map. Matched GPS traces may be processed by a matched segment module to produce proposed changes to the map. The map can be updated using a map updating module based on the proposed changes from the matched segment module. Unmatched GPS traces may be processed by an unmatched segment module to produce proposed changes to the map. The map can be updated using a map updating module based on the proposed changes from the unmatched segment module. The proposed changes to the map may include metadata defining new roads in the map, new intersections in the map, updates to turn restrictions in the map, updates to the allowable directional traffic flow on the roads within the map, updates to road closures in the map.

Abstract translation: 公开了一种更新路线图的技术。 一些GPS踪迹可与地图中的道路相匹配。 匹配的GPS迹线可以由匹配的段模块来处理，以产生对地图的建议的改变。 可以使用基于匹配段模块的建议更改的地图更新模块来更新地图。 不匹配的GPS迹线可能由不匹配的段模块处理，以产生对地图的建议更改。 可以使用地图更新模块根据来自不匹配的段模块的建议更改来更新地图。 建议对地图的更改可能包括在地图中定义新道路的元数据，地图中的新交叉点，更新地图中的限制，更新地图中道路上允许的定向交通流量，更新到地图中的道路封闭 地图。
