Modelling large crowds

The last few days I been reading up on pedestrian models, 3D cityscapes and the simulation of large crowds. One such paper that caught my eye was by Treuille et al. (2006) entitled Continuum Crowds. The abstract of the paper is:

"We present a real-time crowd model based on continuum dynamics. In our model, a dynamic potential field simultaneously integrates global navigation with moving obstacles such as other people, efficiently solving for the motion of large crowds without the need for explicit collision avoidance. Simulations created with our system run at interactive rates, demonstrate smooth flow under a variety of conditions, and naturally exhibit emergent phenomena that have been observed in real crowds."

The movie below shows their work:
