台灣城市街道適步行性評估研究

Research on Walkability Evaluation of Urban Streets in Taiwan

過往適步行性（walkability）研究多採用實地勘察方式進行。美國房地產銷售網站Walk Score®利用地理資訊系統技術建置快速且方便之適步行性評估方法，以地址查詢方式提供各項環境指數，其中包含步行分數。該網站服務範圍未包含台灣，並且步行評分指標偏重商業應用，與步行環境相關較少。參考Walk Score®之適步行性評估方法，本研究將建立適用於台灣城市街道之適步行性評估方法。首先透過文獻回顧歸納影響適步行性各項因子，作為專家問卷之基礎；其後應用模糊德爾菲法進行指標篩選，確定「土地混合使用」、「交通設施可及性」與「步行基礎條件」三大評估面向，及其相對應11項具體評分指標；並應用分析網絡程序法計算指標權重；最後以臺北市大安區之七個次分區，進行步行分數試算。本研究發現大安區步行分數呈現北高南低情形，大安區南部區域與其他地區呈現明顯差異。

In the past, walkability studies were mostly conducted by field surveys. Walk Score®, a US real estate sales website, uses geographic information system technology to build a fast and convenient walkability assessment method, and provides various environmental indicators by address query, including walking scores. The service scope of this website does not include Taiwan, and the walking scoring index focuses on commercial applications and is less related to walking environment. With reference to the walkability evaluation method of Walk Score® , this research will establish a walkability evaluation method suitable for urban streets in Taiwan. Firstly, through literature review, various factors affecting walkability are summarized as the basis of the expert questionnaire. Afterwards, the fuzzy Delphi method was used to screen indicators to determine the three evaluation aspects of ''mixed land use'', ''accessibility of transportation facilities'' and ''basic walking conditions'', and 11 specific scoring indicators corresponding to them. And apply the analysis network procedure method to calculate the index weight. Finally, a trial calculation of walking scores was performed on the seven sub-districts of Daan District, Taipei City. This research found that the walking score of Daan District is higher in the north and lower in the south, and the southern area of Daan District is significantly different from other areas.
