老龄化背景下城轨换乘站客流组织仿真分析

针对人口老龄化背景下的城轨换乘站客流组织问题，从影响因素分析出发，量化老年乘客生理特征对乘客行动力影响的外在表现，并运用社会力模型描述换乘站内行人运动。借助AnyLogic仿真软件，以重庆市某换乘站为实验对象构建地铁换乘站仿真模型。通过设计多场景仿真实验，结果发现老年乘客比例对站内客流速度、进站时间、换乘时间都有明显影响，尤其是在站内客流瓶颈处和高差变化处的影响更为明显。最后，对适老背景下城轨车站设计和运营提出针对性建议。

Simulation analysis of passenger flow organization in urban rail transfer stations under the background of aging

Aiming at the problem of passenger flow organization of urban rail transfer stations under the background of population aging, starting from the analysis of influencing factors, quantifying the external manifestations of the influence of the physiological characteristics of elderly passengers on passenger mobility, and using social force model to describe pedestrian movement in transfer stations. With the help of AnyLogic simulation software, a subway transfer station simulation model is constructed with a transfer station in Chongqing as the experimental object. By designing a multi-scenario simulation experiment, it was found that the proportion of elderly passengers has a significant impact on the passenger flow speed, entry time, and transfer time in the station, especially at the bottleneck of passenger flow and the change of height difference in the station. Finally, some suggestions are put forward for the design and operation of urban rail stations under the background of suitable for the elderly.
