An evacuation process is simulated within the Social Force Model. Thousand pedestrians are leaving a room by one exit. We investigate the stationarity of the distribution of time lags between instants when two successive pedestrians cross the exit. The exponential tail of the distribution is shown to gradually vanish. Taking fluctuations apart, the time lags decrease in time till there are only about 50 pedestrians in the room, then they start to increase. This suggests that at the last stage…

Strategies in crowd and crowd structure
The results of the simulations within the Social Force Model indicate that the ordered phase can be detected as an increase of spatial order of positions of the pedestrians in the crowd.
Enhancing Crowd Evacuation and Traffic Management Through AmI Technologies: A Review of the Literature
This document is a review of the burgeoning literature on the utilisation of AmI (Ambient Intelligence) technology in two contexts: providing support and enhancing crowd evacuation during emergencies
How Many Parameters To Model States Of Mind?
It is argued that for computational reasons, complex models with many parameters are less suitable.


Simulation of pedestrian crowds in normal and evacuation situations
Starting with a short review of the available literature in the field of pedestrian and evacuation research, an overview is given over the observed collective phenomena in pedestrian crowds. This
Friction effects and clogging in a cellular automaton model for pedestrian dynamics.
A recently introduced cellular automaton model for pedestrian dynamics is extended by a friction parameter mu, which controls the probability that the movement of all particles involved in a conflict is denied at one time step.
Simulating dynamical features of escape panic
A model of pedestrian behaviour is used to investigate the mechanisms of panic and jamming by uncoordinated motion in crowds, and an optimal strategy for escape from a smoke-filled room is found, involving a mixture of individualistic behaviour and collective ‘herding’ instinct.
Effects of Motivation and Cabin Configuration on Emergency Aircraft Evacuation Behavior and Rates of Egress
Evidence from aircraft accident investigations suggests that the behavior of the passengers during the course of an emergency evacuation can have a dramatic effect on their survival chances. In some
A Fluid-Dynamic Model for the Movement of Pedestrians
A fluid-dynamic description for the collective movement of pedestrians is developed on the basis of a Boltzmann-like gas-kinetic model that can be compared to real situations and possible applications to town- and traffic-planning are outlined.
