Abstract: Summary Floor field model is a cellular automaton model, which reproduces characteristics of pedestrian dynamics such as an arch phenomenon and lane formation. In the floor filed model, pedestrians move similarly whether they are near an exit or not in egress processes. In reality, pedestrian move fast if they are far from the exit, but move slowly around the exit since they try to avoid conflicts with other pedestrians. The new parameter which represents this phenomenon is introduced to the floor field model. We study egress processes by simulation and cluster approximation and obtained an expression of an average flow of pedestrians going out from the exit when they move to the exit directly. The suitable pedestrian mood and the optimal exit position are also discovered by our analysis.
