Trajectory Data Mining for Road Network Updates and Route Deviation Detection

The paper shows how DiDi’s massive driver‑trajectory data can be mined with clustering, map‑matching, and deep‑learning techniques to automatically refine intersection positions, calibrate road‑network topology, and detect both individual detours and collective road‑closure anomalies, enabling real‑time map improvements and safety services.
