基于客流模拟的沈阳地铁1、2号线换乘站改造设计研究

摘要

通过对沈阳地铁1、2号线换乘站改造设计过程中引入客流仿真模拟技术,在现状客流分析的基础上得出该站整体客流密度、高密度分布区域及持续时间,结合其他城市客流发展规律,进行客流预测,建立客流仿真模型,通过客流仿真模拟分析得出该站拥堵原因和改造设计思路,包括提升运能和局部土建改造两个方面,为今后类似的工程改造设计提供参考.%The passenger flow simulation technology is introduced in the process of the transfer station reconstruction design of Shenyang metro line 1 and 2,and the metro station's overall passenger flow density,high density distribution area and duration are obtained based on the present passenger flow analysis.With reference to the development of other cities'passenger flow,we are able to forecast the passenger flow and establish the passenger flow simulation model.Thus,by means of the passenger flow simulation and analysis,the causes of congestion of the metro station and two reconstruction design focuses are clarified,including transportation capacity improvement and partial civil reconstruction,which may provide reference for similar engineering reconstruction design in the future.
