A probabilistic travel demand model generates hourly OD matrices from four inputs (city populations, intercity distances, yearly vehicle‑km, yearly truck trips) and yields 3.3 million daily trips across 60 selected cities (3,600 OD pairs); matrices import to SUMO mesoscopic + dynamic user equilibrium assignment, calibrated against 50 traffic counts (average GEH 4.9, >78% <7.5) and validated with Google Distance Matrix travel times (good R²); runs ~1 hour per DUE iteration; excludes cross‑border through trips and treats trucks like passenger cars.
