[P2P-F] important advance in network theory approaches

Sat Sep 17 04:02:19 CEST 2011

For Brownian ( and other ) models of pedestrian ( and other) traffic
flows Dirk Helbing is key.
Early work is around 1998.

A Mathematical Model for the Behavior of Pedestrians
Helbing
at arxiv.org, 18 May 1998

Models for Pedestrian Behavior
Helbing
at arxiv.org, 13 May 1998

Self-Organization Phenomena in Pedestrian Crowds
Dirk Helbing and Peter Molnár, "Self-Organization
Phenomena in Pedestrian Crowds," in Self-Organization of Complex
Structures: From Individual to
Collective Dynamics, ed. F Schweitzer (London: Gordon and Breach, 1997).
at arxiv.org, 11 Jun 1998

Social force model for pedestrian dynamics
Dirk Helbing and Peter Molnar
at arxiv.org, 20 May 1998

"Helbing’s (1992) mathematical model of the flow of pedestrians going
into different directions, and thus unintentionally hindering each
other’s movements, in the same way that molecules in a fluid collide
with other molecules, thus producing physical friction."
Helbing D. (1992) A Fluid Dynamic Model for the Movement of
Pedestrians, Complex Systems 6,
391-415

"the behavioral force model of pedestrian motion"
Self-organizing pedestrian movement
Helbing, Molnar, Farkas, Bolay
Environment and Planning B: Planning and Design 2001, volume 28, pages 361 ^ 383

“realistic traffic dynamics from which analysts using TRANSIMS
Fire escape agent-based simulation (live simulation available at
www.helbing.org”
from
Helbing, D., Farkas, I. & Vicsek, T. (2000) Nature (London) 407, 487– 490.

hope that helps.
it helped me :-)
