Abstract

Discrete modelling of pedestrian dynamics often defines the system geometry on a two-dimensional regular grid. In a simulation system of this category, the individual pedestrians are associated with a fixed exclusive personal space, since they are to be positioned in the corresponding grid cells. However, empirical data show that in low density range, the size of this personal space varies significantly. The purpose of this paper is to present a new method for the density control in pedestrian dynamics on a regular grid while offering a step calculation mechanism for the simulated pedestrians free of local conflict.
