Journal ArticleDOI
Simulation of evacuation processes using a bionics-inspired cellular automaton model for pedestrian dynamics
TL;DR: It is shown that the variation of the model parameters allows to describe different types of behaviour, from regular to panic, in simulations of evacuation processes using a recently introduced cellular automaton model for pedestrian dynamics.
Journal ArticleDOI
Friction effects and clogging in a cellular automaton model for pedestrian dynamics.
TL;DR: 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.

Extended floor field CA model for evacuation dynamics
TL;DR: In this article, the authors investigated the floor field model, a cellular automaton model for studying evacuation dynamics, and proposed a method for calculating the static floor field, which describes the shortest distance to an exit door in an arbitrary geometry of rooms.
Journal ArticleDOI
Simulation of competitive egress behavior: comparison with aircraft evacuation data
Ansgar Kirchner,Hubert Klüpfel,Katsuhiro Nishinari,Katsuhiro Nishinari,Andreas Schadschneider,Michael Schreckenberg +5 more
TL;DR: In this paper, the authors used cellular automata for pedestrian dynamics with friction and compared their results with experimental results on competitive behavior in emergency egress from an aircraft using Monte-Carlo simulations.
Journal ArticleDOI
Discretization effects and the influence of walking speed in cellular automata models for pedestrian dynamics
Ansgar Kirchner,Ansgar Kirchner,Hubert Klüpfel,Katsuhiro Nishinari,Katsuhiro Nishinari,Andreas Schadschneider,Michael Schreckenberg +6 more
TL;DR: It is shown that walking speeds vmax>1 lead to results which are in very good agreement with empirical data, and the variation of vmax has a strong influence on the shape of the flow–density relation.
