台灣以公路交通為都市發展主軸之政策，已違反了永續發展的理念，而為求解決這些課題，以大眾運輸導向發展為規劃理念被提出，其成功的關鍵因素就是以車站週邊土地為核心，提高土地使用強度、混合土地使用及人行步道之都市設計，這些規劃方式稱之為3D原則，國外實證研究指出3D有助於提高大眾運輸的搭乘率，然而國內僅有研究強度、混合對大眾運輸旅次的影響，在步行都市設計層面卻無實證研究，緣此，本文以台北都會區大眾捷運系統中和線頂溪站與景安站為實證研究之對象，透過問卷調查與迴歸分析發現，TOD設計概念中步行可及性對大眾捷運系統旅次數有正面影響及相關性，最後，本文根據實證之結果，提出空閒距離、連續性與活動強度的人行道設計原則。
Automobile-oriented development in Taiwan was going from sustainable development. Transit-oriented development concepts are applied to outcome this problem. The most important implementation tools are high density, diversity of land use and pedestrian-oriented design, so called 3D, around transit station areas Experiential researches proved that 3Ds are contributive to raise transit trips. Although high density and diversity are also contributive to raise transit trips in Taiwan, no one discussed about the influences of pedestrian-oriented design on transit trips Therefore, this paper discusses this issue by taking MRT Jhonghe Line Jingan station and Dingxi station for case studies and taking advantage of questionnaire and regression analysis Finally, this paper finds positive relationships between accessibility in TOD concepts and mass rapid transit trips and then makes up strategies.
