轨道交通在对外综合交通枢纽集疏系统中的作用与影响因素

对外综合交通枢纽集疏系统工作的顺畅与否对于枢纽乃至城市整体的交通运输具有重要影响。以城市对外交通的综合交通枢纽作为研究对象，以实地调研数据为基础，重点研究轨道交通方式在枢纽集疏系统中的作用及相关影响因素，并提出具有针对性的政策建议。研究结果表明：轨道交通作为综合枢纽集疏系统的骨干，仍有上升及改善的空间；衔接方式、步行距离等衔接设计因素，收入水平、户籍所在地等乘客特征，显著影响轨道交通对集疏系统客流的吸引力；通过优化票证服务及指引服务巩固现有主体客群，利用提高时效性及舒适性的措施争取目标客群，推广轨道交通车站与对外枢纽的一体化设计与统一管理等措施，有利于提高轨道交通对集疏系统客流的吸引力。

The Role and Influencing Factors of Rail Transit in Collection and Distribution System for Integrated External Transport Hub

The operation performance of collection and distribution system for external integrated transport hub is very influential for the traffic of whole city and transport hub. The collection and distribution systems for kinds of external integrated transport hub have been studied. The role and influencing factors of urban rail transit mode in external integrated transport hub collection and distribution system were analyzed based on field investigation data, followed by strategies and suggestions. The results show that: urban rail transit, as the backbone of an collection and distribution system for integrated transportation hub, still need further improvement; transfer factors (include transfer mode, walking distance), and passengers factors (include income level, residence location), have significant impacts on the rail transit attractiveness for passenger flow in collection and distribution system; several strategies can be used to develop attractiveness of urban rail transit, like optimizing ticket service and guidance services to consolidate existing passengers, improving speed, frequency and comfort measures to acquire targeting passengers, promote the integrated design and unified management of rail transit station and external hub design and management .
