Cellular Automaton Approach to Pedestrian Dynamics - Theory
نویسنده
چکیده
We present a 2-dimensional cellular automaton model for the simulation of pedestrian dynamics. The model is extremely efficient and allows simulations of large crowds faster than real time since it includes only nearest-neighbour interactions. Nevertheless it is able to reproduce collective effects and self-organization encountered in pedestrian dynamics. This is achieved by introducing a so-called floor field which mediates the long-range interactions between the pedestrians. This field modifies the transition rates to neighbouring cells. It has its own dynamics (diffusion and decay) and can be changed by the motion of the pedestrians. Therefore the model uses an idea similar to chemotaxis, but with pedestrians following a virtual rather than a chemical trace.

Simulation of evacuation processes using a bionics-inspired cellular automaton model for pedestrian dynamics
We present simulations of evacuation processes using a recently introduced cellular automaton model for pedestrian dynamics. This model applies a bionics approach to describe the interaction between the pedestrians using ideas from chemotaxis. Here we study a rather simple situation, namely the evacuation from a large room with one or two doors. It is shown that the variation of the model param...
متن کاملA generic and hybrid approach for pedestrian dynamics to couple cellular automata with network flow models
Large pedestrian dynamics scenarios are difficult to simulate by models with high spatial resolution in reasonable time, due to high computational costs. Possible solutions are hybrid approaches, which combine models of different spatial scales. On the macroscopic scale, network flow models are used to model pedestrian dynamics. These models reduce the scenario to a simple network of nodes and ...
متن کاملCellular Automata Based Model for Pedestrian Dynamics
We construct a two dimensional Cellular Automata based model for the description of pedestrian dynamics. Wide range of complicated pattern formation phenomena in pedestrian dynamics are described in the model, e.g. lane formation, jams in a counterflow and egress behavior. Mean-field solution of the densely populated case and numerical solution of the sparsely populated case are provided. This ...
متن کاملAn intelligent floor field cellular automation model for pedestrian dynamics
A stochastic cellular automata (CA) model for pedestrian dynamics is presented. Our goal is to simulate different types of pedestrian movement, from regular to panic. But here we emphasize regular situations which imply that pedestrians analyze environment and choose their route more carefully. And transition probabilities have to depict such effect. The potentials of floor fields and environme...
