基于客流仿真的太原地铁下元站换乘方案设计

Transfer Design of Xiayuan Station of Taiyuan Metro Based on Passenger Flow Simulation

下元站是太原地铁1号线与3号线的换乘站,车站客流集散量大、换乘比例高,工程条件制约车站方案设计,为提高设计的精细化水平,研究采用客流仿真技术对设计方案进行仿真模拟,辅助设计方案决策。首先,根据下元站设计条件,提出十字型换乘和T型换乘设计方案;其次,在对比分析传统评价与动态模拟评价的基础上,提出动态模拟评价指标及取值标准,实现设计方案的量化评价;最后,选择采用ANYLOGIC仿真软件对早高峰时段2种设计方案仿真模拟,结合仿真结果综合分析,推荐采用“一岛两侧+岛式”的十字型换乘方案,适应车站功能需求,且应对客流风险能力更强。

Xiayuan Station is the transfer station of Taiyuan Metro Line 1 and Line 3.Passenger flow and transfer ratio is high,and the engineering conditions restrict station design.In order to improve refinement of design,passenger flow simulation technology is adopted to simulate station operation process and assist decision-making.Firstly,according to the design conditions of Xiayuan station,two design schemes of cross-shape interchange and T-shape interchange are proposed.Secondly,based on the comparative analysis of traditional evaluation and dynamic simulation evaluation,the evaluation index and value standard of dynamic simulation are proposed to realize the quantitative evaluation of design scheme.Finally,ANYLOGIC is adopted to simulate the two design schemes in the morning rush hour.Combined with the comprehensive analysis of the simulation results,the cross-shape transfer scheme of"one island with two side platforms+one island platform"is recommended,which could meet the functional requirements of the station and have a stronger ability to deal with the risk of passenger flow.
