考虑乘客流量和节点重要度的地铁站信息查询台优化布置

地铁站多位于地下空间且结构复杂，其内部诱导设施应为乘客提供便捷、高效的服务. 考虑节点重要度，对既有客流量模型进行修正，以区域诱导信息量最大为目标，构建乘客诱导设施布设位置选择模型. 以北京地铁西直门站为例，对地铁站内部诱导设施现状调研，设计调查问卷对诱导设施效能进行分析，运用所构建的选择模型对地铁站信息查询台的布设位置进行求解. 结果表明，西直门地铁站内部的24 个布设位置备选点中，可优选设置7 个诱导设施查询台，使诱导信息有效增量最大. 研究成果可为地铁站内部诱导设施的优化布置提供理论参考依据.

Optimal Layout of Subway Station Information Query Platform Considering Passenger Flow and Node Importance

Metro stations are mostly underground space and have complex structures. Induction facilities should provide more convenient and efficient services for passengers. Based on the existing passenger flow model, considering the importance of nodes, the existing model is revised, and the location selection model of passenger guidance facilities is constructed to maximize the amount of regional guidance information. Taking Xizhimen Station of Beijing Metro as an example, this paper investigates the status quo of induction facilities in metro stations, designs questionnaires to analyze the effectiveness of induction facilities. The proposed selected model is used to solve the location of information inquiry platform of metro stations. The results show that among the 24 locations in Xizhimen Metro Station, 7 inquiry tables for guidance facilities can be selected. Now, the effective increment of guidance information is the greatest. The research results can provide a theoretical reference for the optimization of guidance facilities in metro station.
