本研究以健康社區與TOD之理念作為核心架構，並結合Space Syntax之理論基礎，強調以「步行」為主的都市設計做為發展框架，據以提供一套具理論基礎且可操作於TOD區的評估規劃模式。從台灣都市環境與TOD發展現況觀察，發現對於TOD規劃僅能以距離場站的遠近作為主要衡量基準之原因，乃在於缺乏考量各個TOD區的環境差異性與條件適地性，其各區在地條件與環境現況有所不同，尤其區內步行路網結構的連結關係更存在差異，進而將TOD區分為兩種型態，即TOD-W(步行)與TOD-P(私人運具)兩種不同次模式，並據以提出TOD之6D元素，即新增考量「大眾運輸範圍內之差異性與適地性(Difference)」，以此形塑TOD規劃理念之嶄新的風貌。本文主要分為三大主軸：(一)應用模糊德爾菲法(FDM)分析建立出14項TOD健康步行友善環境評估指標之體系，並結合灰色理論之概念，擬以灰色分析網絡程序法(Grey-ANP)獲得灰色權重，以及提出「彈性決策」方式；(二)續以運用Space Syntax進行案例地區步行路網量化分析，藉由突破對於步行研究的限制，使軸線與拓撲轉換可妥善考量步行空間，亦使地區便捷值(R3值)之結果更為真實反映路網狀況；(三)最後導入TOD健康步行友善環境指標系統，進一步改良地區便捷值，以建構TOD區空間再結構之規劃模式，並透過捷運府中站、板橋站、新埔站、江子翠站等作為實例研究，繼而分析出TOD步行環境之友善值(Rw值)，並從TOD之6D規劃理念的觀點，加以檢視TOD區內健康步行友善環境發展現況及進行綜合討論。
This study takes the concept of healthy community and Transit-Oriented Development (TOD) as the core structure, and the theory of Space Syntax is combined to emphasize the “pedestrian walking” based design as the framework for urban development, by which an evaluation model with theoretical basis and applicable to TOD areas for urban planning is suggested. An observation of Taiwan's current urban environment and TOD development shows that the TOD planning is solely based on the distance from the station because of the lack of consideration of the environmental differentiation and local applicability among the TOD areas, where the connectivity of the pedestrian walking networks are so different that and the TOD areas are divided into two categories, namely, TOD-W (walking) and TOD-P (private vehicle), and thus the 6D elements of TOD are brought up by adding a new consideration of "differentiation and local applicability within the reach of mass transit" and thereby a brand new idea of TOD planning comes into shape. This paper comes with three main proceedings. The first is applying the Fuzzy Delphi Method (FDM) to analyze and establish 14 indicators for assessment of friendliness in a TOD healthy walking environment, and then combining the concept of grey theory with the Grey-ANP method to obtain the gray weights by which a "flexible decision-making" approach is proposed. The second is using Space Syntax for quantitative analysis of the pedestrian walking networks in the studied TOD areas, and then breaking the constraints on the studies of pedestrian walking so that the walking space in the conversion between the walking axes and topology can be properly taken into account, and therefore the resulted local integration values can more truly reflect the status of the walking network. Finally, an indicator system is introduced to evaluate friendliness of the TOD healthy walking environment for further improvement of the local integration, so as to construct a planning model for space restructuring of the TOD areas. Case studies of the MRT Yunfuzhong Station, Banqiao Station, Xinpu Station, Jiangzicui Station are given to obtain the values of friendliness in the TOD walking environment, and then from the perspective of TOD’s 6D planning concept, the current status of developing friendly healthy walking environment in the TOD areas are examined and discussed.
