Morphological and dynamical aspects of the room evacuation process

Mostrar todas las versiones(2)

We study the evacuation of a set of 200 pedestrians from a room under a state of panic. The dynamics of the pedestrians is given by the Social Force Model. The degree of panic is controlled by a parameter vd which represents the velocity at which pedestrians wish to move. We show that the "fast...
