| 摘要: |
| 为研究突发大客流下地铁车站客流控制的安全管理措施,重点关注地铁突发大客流的疏散,考虑供需失衡下的疏散策略优化,通过对多个车站协调控制客流,减轻突发大客流对地铁系统的冲击.突发大客流主要包括节假日大客流、大型活动大客流、恶劣天气大客流和地铁故障大客流4种类型.以对突发大客流形成的内在机理研究为基础,建立以乘客平均延误最小和各区间满载率之和最大为目标的协调限流控制优化模型,利用所求解的控流率为客流控制措施提供量化依据.最后通过算例分析,对比采取与不采取协调限流措施两种情况下的控流率和滞留人次,验证了协调限流模型的有效性和可靠性. |

| Abstract: |
| 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. |
