The paper uses Anylogic simulation software to take the Nanjing South Railway Station departure platform as an example to set up evacuation routes and evacuation numbers and establish an evacuation simulation model for different personnel structure ratios by analyzing the video surveillance of Nanjing South Railway Station. Evacuation flow and evacuation time are analyzed by comparing different evacuation modes. The result shows: (1) The evacuation can be completed within the prescribed time when the departure platform accommodates 4,000 and 6,000 people respectively. (2) The fewer people the evacuation platform accommodates, the shorter the evacuation time used, and the more efficient the evacuation is. (3) Different proportion of personnel age structures have an impact on evacuation flow and evacuation time, the evacuation flow is larger and the evacuation time used is shorter when the middle-aged population accounts for a higher proportion.
