The emergency evacuation process and evacuation time of pedestrians are affected by many uncertain factors. Choosing the typical pedestrian facilities in a rail transit terminal, corridors and stairs, as research objects, the influence factors of pedestrian emergency evacuation in these two types of facilities were studied by analyzing the structural characteristics of facilities. The qualification of safety evacuation and the randomness of evacuation time were analyzed. Defining that pedestrian can arrive at the safety area before disaster happened as a successful safety evacuation and choosing the probability of a successful evacuation as the reliability index of emergency evacuation, the stochastic model was established considering connectivity of the facilities, travel time, capacity and other factors. Finally, a case application is taken to make reliability measurement and evaluation method understandable. Conclusion of the research can provide references on rail transit terminal designing, emergency organization and safety evaluating.
