Abstract
Simulation modeling is an increasingly popular and effective tool for analyzing transportation problems that are not amendable to study by other means. For any simulation study, model calibration is a crucial step to obtaining any results from analysis. This paper presents a systematic, multi-stage calibration and validation, procedure for microscopic simulation models. The procedure is demonstrated in a calibration, study with a corridor network in the southern California. The model validation results for the study network are also summarized.
