Pedestrian Dynamics - Empirical Results and Model Verification

Armin Seyfried (Juelich Supercomputing Centre, Germany)

The number of models for pedestrian dynamics has grown in the past years. Unfortunately the experimental database to test them is to a large extent inaccurate and contradictory.

The first part of the talk focuses on empirical findings. After a critical review of data from literature and their inconsistencies, a set of experiments designed for model verification are presented. For the analyzes of the experiments, video sequences are analyzed automatically. The extracted pedestrians' trajectories feature high accuracy. Results obtained for the velocity density relation as well as the flow through bottlenecks will be presented.

The second part is dedicated to the modeling of pedestrian dynamics and starts with a brief overview of common modeling approaches. Along with a forced based model continuous in space, general aspects of modeling and model verification are discussed.
