We developed a method for simulating pedestrian dynamics in a large, densecrowd. Our numerical model calculates pedestrian motion from Newton secondlaws, taking into account visco-elastic contact forces, contact friction, andground reaction forces. In our computer simulation, non-spherical shapes(spheropolygons) modelled the positions of the chest and arms in the packingarrangement of pedestrian bodies, based on a cross-sectional profile using datafrom the US National Library of Medicine. Motive torque was taken to arisesolely from the pedestrians orientation toward their preferred destination. Theobjective was to gain insight into a tragic incident at the Madrid ArenaPavilion in Spain, where five girls were crushed to death. The incident tookplace at a Halloween Celebration in 2012, in a long, densely crowded hallwayused as entrance and exit at the same time. Our simulations reconstruct themechanics of clogging in the hallway. The hypothetical case of a totalevacuation order was also investigated. The result highlights the importance ofthe pedestrians density and the effect of counter flow in the onset ofavalanches and clogging, and provides qualitative measures of the number ofinjuries based on a calculation of the contact force network between thepedestrians.
