摘要

隨著科技與經濟成長迅速，交通擁擠問題愈來愈嚴重，因此各國都積極投入如何改善交通問題之研究，其中自動導航系統爲積極研發的技術之一。在導航系統架構中，除了定位、電子地圖比對及指引系統外，路線規劃系統也是極爲重要的一部分，主要是提供駕駛者從起點至目的地的行車參考路線，然而目前之導航系統多以最短路徑演算法來規劃行駛路線，並無對人員主觀之路徑選取規劃深入探討，因此本研究之目的爲探討何者爲行車路線選擇之最優先考慮因素，並討論比較最短路徑法與自動導航路徑結果之差異。然而影響路徑選擇之因素相當多，本研究歸納出33項題目，透過問卷調查及使用因素分析法進行分析，在路徑規劃方面則是提供台北市區地圖供受訪者規劃路徑，透過問卷的調查發現影響路徑選擇因素有七大構面分別爲：交通環境、干擾因素、轉向因素、交通危險性、方便性、車道數量、時間距離，再進一步探討何種因素對駕駛人選擇路線上影響最大，進而提出未來自動導航系統開發之參考。

Many countries are figuring on traffic improvement by innovation technologies (i.e. the vehicle navigation system). The architecture of navigation system includes the positioning, map mapping, and directing system. In addition, the route planning system is also an important part of the navigation system. It is to offer the drivers a path from the beginning to the destination for their reference. However, the route planning usually developed by the shortest path algorithm. The driver's route choice behavior was still unknown. The aim of this study was to explore the effect factors on driver's route choice behavior by factor analysis. Further, we compared the driver's route planning with electronic map and the shortest path algorithm. The results of factor analysis revealed that traffic environment, interference, change direction, traffic hazard, convenient, the number of lanes and distance/time were important components of route choice behavior. The driver's route planning did not depend only on distance or time factor.
