Abstract:

Most of the traditional passenger flow control methods for metro system aim to reduce the total passenger waiting time or maximize the passenger person-kilometers, while lack of emphasis on safety elements. Constraining the total passenger waiting time under an acceptable range, this paper proposes a safety- oriented cooperative passenger flow control model, which aims to minimize the total risk value of the passenger accumulation. The proposed model is successfully converted to an integer linear programming model with a single objective, which can be solved by CPLEX solver. From the experimental results of a real world case, we can find that, compared with passenger control which aims to minimizing the total passenger waiting time, our model can control the passenger accumulation at all stations in the safety level, meanwhile the total passenger waiting time only increases by 1%. As the proposed method can improve the operational safety to a great extent, it might offer well guidance to the passenger flow control in reality.

摘要：

传统的客流控制大都以减少乘客等待时间或者客运周转量最大为目标，缺乏对于安全性的考虑.保证乘客等待时间在可接受范围以内，以客流聚集预警值最小为目标，提出了以安全为导向的地铁高峰时段多车站客流协同控制模型，并成功将其转化为单目标线性整数规划模型，借助CPLEX优化器可直接进行求解.以某地铁线路高峰客流数据为例，通过计算得出，相对于以乘客等待时间最小为目标的客流控制方法，本文方法在保证乘客总等待时间仅增长1%的情况下，能够将所有车站客流聚集控制在安全范围以内，大大提高了客运组织安全性，为实际客流控制提供了很好的依据.
