Zusammenfassung: | A routing module identifies POIs that can be reached from a route with a cost less than distance m. A routing engine performs a reverse exploration on nodes in the planned route to locate POIs from which the route can be reached with a cost of less than a second cost n. POIs identified as being reachable from the route with a cost of less than m, and from which the route is reachable with a cost less than n are then further filtered to identify a subset of the POIs for which the sum of the time or distance from the route to the POI and the time or distance from the POI back to the route is less than a threshold time or distance, t. |
