EMPIRICAL RESULTS FOR PEDESTRIAN DYNAMICS AND THEIR IMPLICATIONS FOR MODELING

The current status of empirical results for pedestrian dynamics is reviewd. Suprisingly even for basic quantities like the flow-density relation there is currently no consensus since the results obtained in various empirical and experimental studies deviate substantially. We report results from recent large-scale experiments for pedestrian flow in simple scenarios like long corridors and bottlenecks which have been performed under controlled laboratory conditions that are easily reproducible. Finally the implications of the unsatisfactory empirical situation for the modeling of pedestrian dynamics is discussed
