Influence of the exits’ configuration on evacuation process in a room without obstacle

The floor field model is the most popular cellular automata (CA) model which is used to simulate the pedestrian’s behaviors. In the floor field model, the interaction between pedestrians is expressed by the dynamical field. In this paper, we proposed an improved and simple method to calculate the floor field. In our method, the pedestrians are treated as the movable obstacles which will increase the value of the floor field. The additional value is interpreted as the blocking effect of preceding pedestrians. And then, the influence of the exits’ configuration on evacuation process in a room without obstacle is simulated. The evacuation time for different widths and positions of the exits is investigated.
