Research on Spatial Arrangement of Metro Station Floor Facilities Based on Pathfinder

The process of China's large-scale urbanization is constantly advancing, and public transportation problems are increasingly prominent. In recent years, major cities have been building subways. The advantages of the subway, such as fast and low carbon, have become an important means for large cities to solve urban public transportation. With the development of urban subway construction technology and operation scale and the continuous improvement of people's safety concept, the problem of evacuation of people in emergencies such as fires has increasingly aroused people's understanding. In order to explore the influence of the location of the facility space on the station floor to the evacuation of people in the event of an emergency, this paper optimizes the analysis of the traffic facilities such as the automatic ticket gate and the guide railing in the public area of the subway based on the pathfinder evacuation software. The location of the facility space at the station floor of the subsequent construction has been actively assisted. The simulation results show that the opening of the guide rail at the gate and the entrance and exit of the security inspection has a restraining effect on the evacuation of personnel; the spatial arrangement of the subway gate has a significant impact on the evacuation of personnel, and the layout of the distributed gates is not correct. The personnel at the exit of the escalator caused blockages, which was better than the centralized arrangement.
