大眾運輸導向車站周邊步行友善環境規劃之研究──以板橋車站為例

Walking-Friendly Environmental Planning Around the Transit-Oriented Development Station - Using Banqiao Station as an Example

本研究以TOD 理念結合Space Syntax 之理論基礎，強調以「步行」為主的環境規劃做為發展框架。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 與TOD-P 兩種不同次模式，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(Differentiation) 與適地性」，並建構其可評估之代表意涵，以此形塑TOD 規劃理念之嶄新的風貌。本研究主要運用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) 之結果更為真實反映步行路網狀況，並進一步改良出TOD 區步行友善環境值(Rw)，加以檢視車站周邊步行環境發展現況及進行綜合討論。

This research combines the TOD (Transit-Oriented Development) concept with Space Syntax network analysis method to construct the elements (6D) that should be considered in walking-friendly environmental planning around the TOD station and as a guide for urban development. Our observation of current TOD development in Taiwan suggests that walking environment planning in surrounding areas of MRT stations is solely based on distance centered from a station. Because of the lack of consideration of different local applicability among the TOD areas, the road conditions are quite different in each locality and environment. Especially, the connectivity of the pedestrian walking networks among the localities varies. Therefore, the TOD areas are divided into two categories, namely TOD -W (walking) and TOD-P (private vehicle). Additionally, the 6D elements of TOD are brought up by adding a new consideration of “differentiation and local applicability within the reach of mass transit”, formulating an evaluation system to study its significance. To find a novel concept of TOD development, this study applies Space Syntax to quantitatively analyze the pedestrian walking networks. The pedestrian space can be properly considered by breaking the limits of ‘walking’ analysis, under the circumstance of axis and topology conversion. The locality convenience value (R3) can illustrate the reality of the pedestrian network. Furthermore, the TOD walking environment friendliness value (Rw) can be concluded to improve the study. Evaluating the walking environment current condition around the station with these methods, a comprehensive discussion can be conducted.
