This paper summarizes the calibration procedure and the final results of calibration of the transport model METROPOLIS for Ile-de-France region. It also presents a brief description of the different sources of data available and their uses for modeling and calibration purposes. Calibrations results were compared on both aggregate and disaggregate level with the field data obtained from different sources. The results suggest that METROPOLIS, which is a dynamic traf-fic simulator, can give precise prediction of the real traffic situation for Ile-de-France region.
