Abstract: The simulation of pedestrian evacuation in emergency is of great significance to the public facilities design and emergency plan implementation. For study pedestrian behaviors under emergency, this paper first analyzes emergency and pedestrian characteristics. In order to describe the spread effect of emergency on pedestrian evacuation process, the concept of emergency diffusion field is put forward. In addition, the concept of panic coefficient is put forward in order to depict the effect of pedestrian panic psychology on the evacuation process. Then, the floor field model consisted of static floor field, dynamic floor field and emergency diffusion field is established, the corresponding updating rules are defined. Finally, the experiments results reproduce the pedestrian evacuation process under different conditions, and the influence factors in the process of pedestrian evacuation are analyzed, verify the validity of the model
