Shortcuts: For common scenarios, we pre-calculate the travel time/distance (the "shortcut") between border points within the same cluster and also to border points of immediately adjacent clusters.

This map illustrates the OsmAnd routing concept. The route starts in the Start Area Cluster (221558), moves to the nearest Border Point, and continues through precomputed Shortcuts across intermediate clusters. It then enters the Finish Area Cluster (221536) via another border point and finishes using local roads. This method speeds up routing by combining local search with efficient inter-cluster shortcuts.，更多细节参见safew官方版本下载
