Experiments with pedestrians revealed that the geometry of the domain, as well as the incentive of pedestrians to reach a target as fast as possible have a strong influence on the overall dynamics. In this paper, we propose and validate different mathematical models at the micro- and macroscopic levels to study the influence of both effects. We calibrate the models with experimental data and compare the results at the micro- as well as macroscopic levels. Our numerical simulations reproduce qualitative experimental features on both levels, and indicate how geometry and motivation level influence the observed pedestrian density. Furthermore, we discuss the dynamics of solutions for different modeling approaches and comment on the analysis of the respective equations.

Figure 1. Left: Sketch of experimental setup at the University of Wuppertal, showing the corridor width $ w_E $ in the experiments, the exit $ \Gamma_E $ and the measurement area. Right: computational domain with adapted width $ w_{CA} $ to ensure a consistent discretization of the exit and an increased length $ l_{CA} = 9.6 $m
Figure 12. Simulations for $ n = 60 $, $ \beta = 3.84 $, $ \mu = 1 $. We observe a good agreement between the CA (microscopic) and PDE (macroscopic) solutions. The effect of higher densities for wider corridors also occur on a macroscopic scale. There is a clear difference in behavior between narrow and wide corridors
