Abstract: In order to study the evacuation of people in a subway transfer station fire during peak period, taking JMS subway transfer station as the object, the building information model was established by Revit. Six kinds of fire scenarios were simulated by Pyrosim, and the failure critical values of all passing facilitieswere studied by taking the temperature, CO concentration and smoke visibility as safety indexes. The pedestrian parameters such as age, gender, weight and speed were added. The evacuation time, evacuation flow and evacuation bottleneck were discussed by Pathfinder. The results show that the evacuation fails under scenarios A2 and C2; Pedestrians are more inclined to pass facilities around during the escape process, leading to neglect of the best route; some facilities are idle when the evacuation bottleneck occurs in other passing facilities, which leads to the phenomenon of low utilization rate of facilities and low evacuation efficiency. Finally, optimization suggestions are put forward for the situation.

Key words: subway transfer station, fire, passing facilities, evacuation bottleneck
