Microscopic Modeling of Evacuation Processes: Empirical Data and Simulation Results — •Andreas Keßel, Hubert Klüpfel, and Michael Schreckenberg — Physics of Transport and Traffic, Gerhard-Mercator-University Duisburg

Since the size of pedestrian facilities increases there is the need for a detailed evacuation analysis is increasing, too. Full scale tests are very expensive and in most cases not feasible. So the use of a simulation tool is sensible. Since it is highly recommended in this field that a simulation produces reasonable results it must be compared to reality.

The simulation used is based on a Cellular Automaton (CA) model for pedestrian motion. The pedestrians are represented as individuals. This model was originally developed for the evacuation simulation onboard passenger vessels but due to its high flexibility it is also usable for the simulation of other facilities like shopping malls or football stadiums. The high processing speed enables for the simulation of about 10.000 pedestrians in real time.

We give an overview of our model and show some sample applications. The influence of the different parameters on the simulation result (sensitivity analysis) is investigated. Recorded evacuation exercises are compared to simulation results. Finally, crucial points in the adjustment of the parameters are explained. If the parameters are adjusted properly, a good agreement to real exercises can be reached.
