Monitoring Path Nearest Neighbor in Road Networks

Summary: Defines k-Path Nearest Neighbor (k-PNN) for a moving user: k candidates tied to the shortest path between current location and destination. Proposes Best-first Network Expansion (BNE), a three-phase (search/verify/monitor) method with an expansion tree to efficiently update shortest paths and k-PNN as routes move.
