大型综合铁路交通枢纽客流运行评估研究

Research on passenger flow operation evaluation of large‑scale integrated railway transportation hubs

大型综合交通枢纽汇集多种交通方式于一体,承担着对外交通与市区交通的转换功能,旅客交通行为的日益复杂对枢纽规划设计提出更高要求。考虑到后期运营存在改造局限,建立一套适用的客流运行评估体系,规划阶段前置评估旅客在当前设计方案下的运行效率,识别潜在运营问题,动态反馈以优化设计方案显得尤为重要。本文剖析建筑设施功能布局,梳理客流流线,从整体运行效率、关键流程效率两个角度,以安全性、时效性、通畅性、便捷性、能力适用性等为目标,通过归纳要素、选取指标建立定量化客流评估指标体系。并应用于南京北站规划阶段方案定量比选及改善,为综合性铁路枢纽的设计优化提供依据和建议。

The large-scale integrated transportation hub integrates a variety of transportation modes and assumes the conversion function between external traffic and urban traffic.The increasing complexity of passenger traffic behavior puts forward higher requirements for the planning and design of the hub.Con⁃sidering the limitations of the later operation,it is particularly important to establish a suitable passen⁃ger flow operation evaluation system,evaluate the passenger operation efficiency under the current de⁃sign scheme in the planning stage,identify potential operational problems,and provide dynamic feed⁃back to optimize the design scheme.The paper analyzes the functional layout of building facilities,sorts out the passenger flow line,and establishes a quantitative passenger flow evaluation index system by summarizing elements and selecting indicators from the perspectives of overall operation efficiency and key process efficiency,aiming at safety,timeliness,patency,convenience and capability applicability.It is applied to the quantitative selection and improvement of Nanjingbei Railway Station in the planning stage,and provides basis and suggestion for the design optimization of comprehensive railway hub.
