空間型構理論視角下臺北市大眾運輸導向發展之可及性分析

A Study on Accessibility of Transit-Oriented Development in Taipei from the Perspective of Space Syntax

臺北市政府為推動大眾運輸導向發展，於2019年實施「擬定臺北市大眾運輸導向可申請開發許可地區細部計畫案」，而後因一直未有民間申請案件，於2022年透過計畫變更大幅增加適用場站並放寬覆蓋範圍。然而，由於該計畫之推動主要是以容積獎勵為誘因，計畫變更公告後便引起許多爭議，認為該變更缺乏合理依據並可能衍生都市景觀、交通衝擊等問題。本研究主要目的即在於運用空間型構理論從可及性分析的角度來反思臺北市當前之大眾運輸導向發展：一、現行計畫較缺乏考量場站可及性條件之差異，而將全市所有捷運站均列為適用場站，並指定相同之可申請開發許可範圍。二、不同場站在周圍區域的空間結構與土地使用型態上亦存在很大的差異，但現行僅依據捷運線之運量訂定分級與容積獎勵，而缺乏考量這樣的差異以及引導其朝適地適性方向發展的機制。

 

To implement Transit-Oriented Development (TOD) into practice, Taipei City Government in 2019 issued the “Detailed Plan on Applying Permit for TOD in Taipei.” With no applicants until 2022, the government opted to expand the number of designated MRT stations and broaden the TOD applicable area. However, controversy has mounted since the plan’s inception due to its reliance on floor area bonuses as incentives, prompting concerns over its justification and potential impact on the urban landscape and traffic. By employing the theory of Space Syntax, this study aims to reflect on the current TOD plan of Taipei from the perspective of accessibility analysis: 1. Without considering accessibility conditions, all MRT stations in Taipei are included in TOD plan, each designated with identical development permit areas. 2. Variations in spatial configuration and land-use patterns surrounding different MRT stations are significant. Although in the current TOD plan there is a classification system for determining the amount of floor area bonus, the system solely relies on MRT ridership without accounting for such differences or providing adaptability mechanisms to tailor TOD to local contexts.
