以GIS提昇都市交通問題之解決能力

USING GIS TO ENHANCE THE CAPABILITY OF SOLVING URBAN TRANSPORTATION PROBLEMS

本文針對都市交通中之肇事與停車問題，採用地理資訊系統（GIS）及圖上地址定位技術，分別研擬作業程序以支援都市易肇事地點之尋找、購車自備停車位之認證，以及停車場興建區位之評選。本文除分別說明諸項作業程序之內容外，亦依實例繪出這些作業程序中之成果圖，如肇事與停車對策所需之主題圖、有效範圍圖與服務等距圖等。最後，再以(1)資料整合－－打破分區的界線，(2)操作簡化－－便利資料的處理，(3)空間分析－－幫助方案的產生，(4)方案評估－－衡量準則的績效，以及(5)圖形展示－－增進溝通的效果等GIS功能項目，審視本文以GIS提昇都市交通問題之解決能力。

This paper aims at proposing the process of using GIS and address geocoding to enhance the capability of solving urban transportation problems such as traffic accident and parking problems. The solutions to these problems include the identification of the accident-prone location, the qualification of parking space for car-ownership and the allocation of new parking lots. For each solution, we describe and discuss its process with flow diagrams and procedure statements. Besides, several maps are generated separately for illustration of the thematic data, feasible region and service isoquants for the certain solution. At last, The process for each solution is reviewed in terms of (1) data integration, (2) easy manipulation, (3) spatial analysis, (4) alternatives' evaluation, and (5) graphic illustration to justify the advantage of using GIS to support solving urban transportation problems.
