Efficient Label-Constrained Shortest Path Queries on Road Networks: A Tree Decomposition Approach
Summary: Proposes LSD-Index, a tree-decomposition-based index for label-constrained shortest-path queries in road networks. Demonstrates orders-of-magnitude speedups, reduced index space, and scalable parallel index construction on large-scale networks (e.g., USA road network). (summarized by gpt-5-nano on Feb 09 2026)
