地铁换乘枢纽设施能力测度方法及其适应性分析

Measurement and adaptation analysis of their facilities capacity for the subway passenger terminal

基于行人流特征与枢纽内部设施服务状态的特征分析,确定了各类设施的能力测度方法,并从定量角度分析了设施能力不足和闲置两种现象产生的原因,进而以满足枢纽内行人流线顺畅为前提,提出了个体和整体适应性分析指标,建立了以行人流线为仿真对象的地铁枢纽站仿真系统,分别对单一设施和整体设施进行了设施能力的个体适应性和整体适应性分析。结果表明,借助于系统仿真方法可实现设施配置方案的参数选择与仿真优化,并给出合理的、提高适应性的改善途径,为枢纽站的设施运营管理和优化配置提供了决策依据。

Based on characteristics analysis of passenger flow and service state of inner facilities in passenger terminal,measurement of facilities capacity for each type of facilities was determined.Reasons were analyzed in a quantitative view which two phenomena brought.Furthermore Indexes for individual and whole adaptation analysis were offered under the precondition to satisfy smooth passenger streamlines in terminal.While simulation system of subway passenger terminal was also established with the object simulated as passenger streamlines,individual and whole adaptation analysis were hereby performed respectively for individual facility and all facilities.Results show that parameter selection and simulating optimization for facilities allocation can be accomplished by means of system simulation integrated with measurement of facilities capacity and indexes of adaptation analysis.Some reasonable improvement approaches are represented to enhance adaptability of facilities capacity and its decision basis is thereby provided for the operation management and optimal allocation of facilities in terminal.
