Route choice calibration from multi-point vehicle stream measurements

Abstract

To better und more precisely assess different transporta-tion design alternatives and traffic management strategies, microscopic traffic simulation models are extensively applied. The respective calibration and validation works are getting more and more important. Nowadays, GPS-based systems are broadly applied. More and more route related information can be collected, which promises great improvements of calibra-tion accuracy. An approach using multi-point vehicle stream measurements is proposed in this paper and is shown to work well in synthetic experiments.
