Crowd Dynamics; Modeling, Calibraton, and Empirical Findings — •Anders Johansson and Dirk Helbing — Institute for Transport and Economics, TU Dresden

In the field of pedestrian modeling, a variety of models are used. These models are differently accurate and based on different assumptions and approximations. In this contribution we present a quantitative study of properties of crowds, extracted from empirical trajectory data. From these properties, we discuss which have a large impact on the overall crowd dynamics, and which might be neglected in a simulation model.

Parallel to this, we present a new generic method, based on an Evolutionary Algorithm, for calibrating pedestrian models to empirical trajectory data. As a special case, we present a calibration of an updated Social-Force Model.
