A methodology to calibrate pedestrian walker models using multiple objectives

The application of walker models to simulate real situations require accuracy in several traffic situations. One strategy to obtain a generic model is to calibrate the parameters in several situations using multiple-objective functions in the optimization process. In this paper, we propose a general methodology for calibration of walker models....

The Nomad Model: Theory, Developments and Applications

This paper presents details of the developments of the Nomad model after being introduced more than 12 years ago. The model is derived from a normative theory of pedestrian behavior making it unique under microscopic models. Nomad has been successfully applied in several cases indicating that it fulfils requirements for accuracy, scope and...
