Online calibration with SUMO for network-wide traffic and emission monitoring - Case ITS Huainan
summary
An online SUMO mesoscopic pipeline integrates taxi FCD and stationary sensors, fusing data in Postgres/Oracle and running dsp online calibration every 5-minute intervals to feed the KeepMoving portal. The city network is ~10,000 edges/5,000 nodes (2,600 km) with ~1.34 million daily trips; simulation runs 70–90 s (max 130 s) and total processing <5 minutes. Calibration yields ~80% of flows and ~95% of speeds within 15% absolute relative error; hourly GH ≤5 for ~92% of flows.
