Abstract: To ensure the safety of the evacuation of the outpatient hall, the evacuation simulation and the optimization of the layout of the service windows were carried out. In this paper, several typical window layouts and the number and composition of patients in different outpatient halls are explored through field observations; modifying the fine discrete cellular automaton model by setting different moving and competing abilities based on the field survey data, an evacuation dynamic model for outpatient hall is proposed to simulate evacuation under different window layouts, and further set the special window. The main results include: A layout of windows on both sides is optimal, and the evacuation time is the shortest in this situation; The opposite layout has the highest evacuation fluency; The window layout has a greater impact on the patients with weaker moving ability; Setting priority windows can ensure the priority evacuation of people with disabilities, and setting priority windows on both sides near the exit is the most efficient for evacuation. This study provides support for the design of the service window layout in the outpatient hall and for the crowd evacuation management.
