都市区轨道交通多层次各制式量化选择方法研究

为探讨多层次各制式选择方法的量化问题,更为精准、经济、因地制宜地选择轨道交通制式,在线网规划及相关前期工作时就能够基本确定制式,为后续进一步研究确立基础。汇总市域、大运量、中低运量各类轨道交通制式的技术参数,研究基于客流走廊特征、节点重要度、节点联系强度的轨道交通制式选择方法,并以大西安都市区为实例进行分析,考虑节点重要度、联系强度因素,将走廊客流量级与各制式量级进行匹配,进而确定各走廊适宜的制式。结果表明,通过该方法进行制式选择分析更为精确,能够体现城市结构特征,并满足不同层次的交通需求。

Research on the Quantitative Method of Multi-level and Multi-mode Rail Transit System Selection in Metropolitan Areas

In order to tackle the quantification problem of multi-layer and multi-mode system selection method and select rail transit system more accurately and economically according to local conditions, the system should be basically determined in network planning and related preliminary work to establish the foundation for further research. This article summarizes the technical parameters related to all kinds of transit systems of metropolitan region, large capacity, medium and low capacity. The research is conducted based on the characteristics of passenger corridor, node important degree and node link strength of rail transit system selection method. Analysis of the Xi’an metropolitan area is conducted with focus on the priority of the node importance degree and node link strength, and the traffic corridor flow volume is matched with individual system order to determine the appropriate system of the corridor. The results show that this method is more accurate in selecting the system and can reflect the characteristics of urban structure and meet the traffic requirements of different levels.
