To study the safety management of the sudden large passenger flow in metro stations, this paper focuses on the metro station evacuation and its strategy improvement under high imbalance between demand and supply. To relieve the stress of the sudden large passenger flow during metro system’s operation, a multi-station coordination control method is proposed. The reasons for large passenger flow mainly include holiday period, large-scale events, severe weather, and metro facilities faults. Based on the formation mechanism of large passenger flow, a coordinated current limiting control model was established to minimize the passenger loss delays and maximize the interval load rate, which can provide quantized basis for flow-control management. Finally, through the example analysis, the controlled flow rate and the number of stranded passengers before and after control were compared, and the effectiveness and reliability of the model were verified.
