document: 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 parameters allows to describe different types of behaviour , from regular to panic . We find a non-monotonic dependence of the evacuation times on the coupling constants . These times depend on the strength of the herding behaviour , with minimal evacuation times for some intermediate values of the couplings , i.e. , a proper combination of herding and use of knowledge about the shortest way to the exit
