Cellular automaton model for evacuation process with obstacles

Cellular Automaton Evacuation Model Coupled with a Spatial Game

Professor Harri Ehtamo For web-based real-time safety analyses, we need computationally light simulation models. In this study, we develop an evacuation model, where the agents are equipped with decision-making abilities. As a starting point, a well-known cellular automaton (CA) evacuation model is used. In a CA, the agents move in a discrete square grid according to some transition probabiliti...

A Dynamic Cellular Automaton Model for Large-Scale Pedestrian Evacuation

Cellular Automata Evacuation Model Considering Information Transfer in Building with Obstacles

The buildings are usually divided into two categories in light of whether obstacles exist: the large space with no obstacles (C-type buildings) and the complex buildings with lots of obstacles (L-type buildings). In this paper, considering the aisle region attraction factor, we proposed a revised model which is suitable to simulate the evacuation process in the L-type buildings (such as classro...

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...

A Simpliied Cellular Automaton Model for City Traac a Simpliied Cellular Automaton Model for City Traac

We systematically investigate the e ect of blockage sites in a cellular automaton model for tra c ow. Di erent scheduling schemes for the blockage sites are considered. None of them returns a linear relationship between the fraction of \green" time and the throughput. We use this information for a fast implementation of a simulation of tra c in Dallas.
