階層式路徑選擇地理資訊系統之建構

Abstract

駕駛者透過導航系統的協助，引導駕駛者在不熟悉的路況環境中，清楚的顯示連接起迄點間的行駛路徑。若導航系統透過更快速、更有效率的路徑選取方式與完整的資料庫支援，讓系統所搜尋的路徑更加符合一般駕駛者駕駛行為。 本研究接續程怡誠與曾敬文的研究，透過檢討其階層式路徑選擇方法，將階層式路徑選擇方法不合理處予以修正，將交通分區階層、運輸系統階層、節點與決策準則做一適當探討與調整，經由地理資訊系統軟體（Geographic Information Systems, GIS）—ArcView軟體建立不同的GIS圖檔，表現交通分區、運輸系統與節點，並透過Avenue程式語言的撰寫，將路徑選擇之決策準則整合於GIS，將修正後之階層式路徑選擇方法，實際建構出一套以地理資訊系統為基礎的路徑選擇系統。

Though the assistance of the navigation system, drivers can easily retrieve the route between origin and destination among the unfamiliar (unacquainted) environment. With faster and more efficient route searching approach and more integrated database support, navigation system will retrieve better route which fits in with people driving behavior. The study is following the research of Cherng and Tzeng. By discussing the A Stratificated Approach for Route Selection, we first revise the unreasonable part of the approach and adjust the traffic zone classes, road network classes, the gates of road network through traffic zone and the decision rules. By using ArcView, the Geographic Information Systems (GIS) software, we establish different GIS files to express traffic zone classes, road network classes and the gates of road network through traffic zone. And we also use Avenue programming language to build the decision rules. Finally, we integrate the traffic zone classes, road network classes, the gates of road network through traffic zone and the decision rules to build a GIS-based routing system.
