Evacuation capacity is the foundation of the evacuation plan. Evacuation plans with accurate evacuation capacity can improve evacuation efficiency and decrease losses. To estimate evacuation capacity, the evacuation network is constructed firstly based on different queueing models and the relation between throughput and arrival rate is determined. When it comes to splitting nodes, the choice probability of the next target is calculated by travel time and the reliability of evacuation time. Next, we estimate the capacity of Jianguomen station of Beijing Subway as an example to validate the efficiency of the proposed model. Finally, density, saturation, and blocking probability of each facility are discussed. Results show that the maximum throughput of Jianguomen station is 855 peds/min, which can be approximately regarded as evacuation capacity.
