Continuum modeling of crowd turbulence
WebOct 10, 2007 · A recent study [D. Helbing, A. Johansson, and H. Z. Al-Abideen, Phys. Rev. E 75, 046109 (2007)] has revealed a ``turbulent'' state of pedestrian flows, which is characterized by sudden displacements and causes the falling and trampling of people. However, turbulent crowd motion is not reproduced well by current many-particle … WebSince this model is primarily intended for high-density crowds, I begin with this continuum represen- tation, similar to the Fluid Implicit Particle (FLIP) approach [Brackbill and Ruppel, 1986]. In the continuum formulation, the crowd state is defined in terms of two properties, den- sity ρ (people per m2) and current velocity v.

WebIn highly dense crowds of humans, collisions between people occur often. It is common to simulate such a crowd as one fluid-like entity (macroscopic), and not as a set of individuals (microscopic, agent-based). Agent-based simulations are preferred for lower densities because they preserve the properties of individual people.
