基于GIS的地铁站步行可达性研究

城市快速轨道交通,特别是地铁交通,对于改善城市交通运输,方便居民生活,减轻空气污染,改善城市布局等方面起到巨大作用。由于城市地铁交通枢纽工程建设周期长、造价高,建成后很难再进行较大规模的改进。因此,必须在设计阶段需要对枢纽的服务水平进行评估和预测,以求能够满足远期规划的要求。进行地铁站步行可达性的研究,是为了用步行可达性指标来量化铁路枢纽的客流吸引区域和服务范围,为地铁的线网规划提供参考标准,为规划、设计人员提供一种定量的手段和依据。鉴于此,本文尝试着利用GIS的技术,为地铁站的步行可达性进行计算,提供准确的定量分析结果和可视化的评价结果,供地铁的规划者和决策者分析。

GIS-Based Metro Station Walking Accessibility Research

Urban High -speed rail transport,especially metro traffic,plays a great role in improving the municipal transportation,benefiting the people's everyday life,reducing the air pollution,improving the layout of the city and so on.As we all know,the urban metro transport,whose engineering construction period is long and cost is high,is very difficult to carry on the big scale again the improvement as long as it is built. So in order to meet the requirements of long-term plan-ning,it is necessary to assess and forecast the service level of the metro when in the design stage. Conducting a study on the walking accessibility of the MTR station is to measure passenger flow attention area and the service level of the MTR sta-tion,which can provide the reference standard for subway's wire plan and provide a quantitative means and basis for the de-signers. This article attempts to use GIS technology for the walking accessibility of the MTR station,the results provide an accurate quantitative analysis and visualization of the evaluation results,for planners and designers of the MTR.
