时空异质性视角下轨道站点客流影响研究

Study on the Influence of Passenger Flow on Railway Station from the Perspective of Spatio-temporal Heterogeneity

轨道站点客流预测及其影响因素的互动关系是交通规划中的关键问题,准确识别影响不同站点客流特征的建成环境因素对组织客流具有重要意义。针对地理空间视角下建成环境对站点客流的时空影响程度的问题,以杭州市城市轨道交通为研究对象,汇集刷卡数据、POI建成数据等多源数据,考虑客流的空间异质性与时空特性构建了混合变化系数和固定系数的S-LGWR影响分析模型,识别不同地理空间位置下影响因素相关系数时空变化特征,为线网空间布局优化、运营管理措施制定和高效安全出行引导提供参考。

The prediction of passenger flow at railway stations and the interaction of its influence factors are key issues in transportation planning,and the accurate identification of construction environment factors affecting the characteristics of passenger flow at different stations is of great significance in organizing passenger flow.In this paper,taking Hangzhou urban rail transit as the research object,collecting multi-source data such as credit card data and POI completion data,we constructed the S-LGWR impact analysis model with mixed variation coefficients and fixed coefficients considering the spatial heterogeneity and spatio-temporal characteristics of passenger flow,and identified the spatio-temporal variation characteristics of impact factors for different geospatial locations.This study can provide reference for optimizing the spatial layout of network,formulating operation management measures and guiding efficient and safe travel.
