Abstract |
The problem of pedestrian evacuation has attracted a lot of attention in the last few years. Scientists from many different fields used various mathematical and physical approaches to model and study this phenomenon. Such studies are very important and may lead to an increase in safety and better understanding of the dangers pedestrians face during evacuation. We study two models of pedestrian evacuation based on cellular automata and intelligent agents. We use the static floor field approach and augment it with additional transition rules (random movement and preservation of personal space) in order to model various aspects of human behaviour. Through numerical simulations we investigate pedestrian evacuation from rooms with various geometries (e.g. empty room, classroom). Using heatmaps (density diagrams of pedestrians), average evacuation times, velocity and other parameters we study the effectiveness of evacuation and potential dangers pedestrians may encounter. |
