適用於自行車運動之導航路徑規劃法

A Biking Route Planning Method for Cyclists

本研究開發一適用自行車運動之導航規劃法。利用專屬的數位化電子地圖作為本系統之路徑規劃地圖，以真正符合專業自行車騎士對於體能訓練或業餘騎士挑戰體能極限上的需求。本系統可自動計算路徑起點與終點的距離、山區高度變化與路徑途中坡度變化資訊，提供自行車山區路徑難易度規劃選擇（如：最短路徑規劃、最易路徑規劃、最難路徑規劃），其中最短路徑規劃主要以路徑長度作為考量，最易路徑規劃與最難路徑規劃則考量路徑中高度起伏變化，將起伏變化的走勢轉換為環法自行車賽坡度值，將此量化後作為路徑規劃考量之指標。本研究並以臺中市大坑山區為標的，實際進行實驗驗證，並深入分析實測之結果。

This paper proposes a novel route planning scheme for cycling. Itutilizes an electronic map to incorporate with the specialized bike routeplanning algorithm. The system features the following functions: Bikeroute planning, navigation, and route recommendation and covers the followingoperational modes; the shortest route planning, easiest route planningand hardest route planning. The shortest route planning simply considersthe whole route length as the objective cost. The easiest and hardest routeplanning considers both altitude and length of the route. A combination ofthe altitude and route length is converted to the slope of the Tour of Francefor evaluation of the bike route difficulty ratings. Geographic informationof the Da-Keng mountain area in Taichung City has been utilized as a testingplatform for realization of the proposed route planning method. Real-worldtests have been conducted for demonstration.
