Path Cost Distribution Estimation Using Trajectory Data
Summary: Introduces hybrid graphs that learn time-varying path weights directly from trajectories, avoiding edge-level fragmentation and capturing cross-edge cost dependencies. Selects path covers to estimate query-path joint cost distributions and integrates them into routing. (summarized by gpt-5.6-luna on Jul 24 2026)
