轨道交通复合型快线线站位研究——以厦门地铁9号线为例

Multi-function Express Rail Transit Line Positioning Plan:A Case Study of Xiamen Line 9

为满足都市圈快速出行的要求、量化研究复合型快线的功能与线站位,提出“圈层—结构—走廊—沿线”的宏观到微观的分析理论体系。以厦门地铁9号线为例,分析城市圈层,并建立基于交通态势的可达性模型、空间句法模型,确定线路承担功能;在功能基础上进一步细化对沿线走廊各方式竞合关系、沿线组团分级、沿线覆盖需求的研究,最终确定适宜的速度目标值、线站位方案、运营方案。结果表明,在前期分析中,引进空间量化分析方法确定的厦门地铁9号线复合型快线既能实现同安区快速进岛的目标,又能兼顾沿线覆盖率。

To cater to the demand for fast travel in metropolitan areas and conduct a quantitative analysis of the multi-function line’s role and positioning,we propose a macro to micro analytical theoretical system that follows a“circle layer-structurecorridor-along”framework.Using Xiamen Metro Line 9 as a case study,we analyze the urban circle,develop an accessibility model and spatial syntax model based on traffic situations,and ascertain the line’s carrying function.Building on this functional analysis,we delve into the competitive and cooperative relationships of various routes along the corridor,categorize groupings along the corridor,and explore coverage needs along the corridor.This allows us to define the appropriate speed target value,line location scheme,and operation scheme.The results indicate that our preliminary analysis,which introduces a spatial quantitative analysis method,confirms that Line 9,as a composite express line,can achieve the goal of quick access from Tongan to the island while ensuring coverage along the line.
