This study explores Transit-Oriented-Development (TOD), a healthy community formed by four stations of Taipei MRT Bannan Line: Jiangzicui Station, Xinpu Station, Banciao Station and Fuchu Station Environment as an example, we use Fuzzy Delphi Method (FDM) and Analytic Network Process (ANP), and import Gray System Theory to construct TOD healthy community by Gray-ANP analysis. In this study, based on literature review and evaluation by FDM experts, we completed the selection and establishment of indicator architecture, and set up a set of index system suitable for assessing TOD healthy walking friendly environment by using ANP Gray-ANP Calculated the weight of each index and the priority of the results of the case area to conduct an index system instance analysis and application. The analysis of the case area shows that the current conditions are reflected in the importance of the weight, The top three in sequence were Design (15.55%), Pedestrian streets (12.59%), pollution remediation (11.76%) and Public access to green spaces (10.92%). Subsequent studies suggest that a comprehensive assessment of Taipei MRT (114 stations) be conducted and a comprehensive questionnaire system should be added to further quantify the users feelings.
