都市發展空間結構指標之分析

Abstract

都市發展之空間結構可由點、線、面、體與機能這五個向度來探討。本研究主要是從交通的資料，研定都市點、線、面、體之指標，再輔以人口、產業之指標分析都市之空間發展結構。由交通資料所產生的指標分為六種，分別為：一、都市發展中心性指標；二、都市發展輻射性與環狀性指標；三、交通特性指標；四、運具選擇指標；五、路網執行指標；六、路網結構指標。 經過指標的計算與分析後，我們可知中心性最高三區依序為分區1（中正、中山、大安）、分區8（板橋、永和、中和）及分區6（松山、信義）；而台北都會區之輻射走廊與環狀走廊其上午尖峰與下午尖峰之方向性差異並不大；最後在中心性指標與旅次集中指標之分析中，本研究發現由中心性指標所計算出之台北都會區發展中心，與旅次分佈所集中之地區大致吻合。

Urban development spatial structure can be analyzed in five dimension: node, link, district, density and function. This study mainly establishes the urban indices of node, link, district, density from urban transportation data. To analyze urban development spatial structure, population and industry index are auxiliary indices in the analyzing process. The indices established from transportation data can be classified into six parts: 1.urban development center indices, 2.urban development radiative and circle index, 3.transport indices, 4.mode choice index, 5.network functioning indices, 6.network structure indices. After calculating and analyzing those indices, the results have shown that the top three zones having the centric property are zone 1 (Jhongjheng District, Jhongshan District and Da-an District), zone 8 (Banciao City, Jhonghe City, Yonghe City) and zone 6 (Songshan District, Sinyi District). The final result shows that the centers for urban development concluded by this study are similar to the centers for urban development in reality.
