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. It utilizes an electronic map to incorporate with the specialized bike route planning algorithm. The system features the following functions: Bike route planning, navigation, and route recommendation and covers the following operational modes; the shortest route planning, easiest route planning and hardest route planning. The shortest route planning simply considers the whole route length as the objective cost. The easiest and hardest route planning considers both altitude and length of the route. A combination of the altitude and route length is converted to the slope of the Tour of France for evaluation of the bike route difficulty ratings. Geographic information of the Da-Keng mountain area in Taichung City has been utilized as a testing platform for realization of the proposed route planning method. Real-world tests have been conducted for demonstration.
