P2H: Efficient Distance Querying on Road Networks by Projected Vertex Separators
Summary: P2H uses projected vertex separators to shrink 2-hop distance labels on road networks. Optimized separator selection and index maintenance for dynamic weights yield smaller indexes and ~2× faster queries on large datasets.
