Abstract

In recent years, several approaches for modeling pedestrian dynamics have been developed. Usually the focus is on the qualitative reproduction of empirically observed collective phenomena like the dynamical formation of lanes. Although this gives an indication of the realism of a model, for practical applications as in safety analysis reliable quantitative predictions are required. This asks for reliable empirical data. Here we discuss the current status of one of the basic scenarios, the dynamics at bottlenecks. Here there is currently no consensus even about the qualitative features of bottleneck flows.
