Zusammenfassung:PROBLEM TO BE SOLVED: To provide a method and a system for selecting a course while reflecting roads on which a user traveled appropriately, and a recording medium. SOLUTION: A sectional traveling course generating section 6 receives the traveling track of a vehicle detected at a current position/traveling track detecting section 2 and an optimal course searched at an optimal course searching section 5 and compares them to extract a different road section as a sectional traveling course. A sectional traveling course storing section 7 stores the extracted sectional traveling course along with the attributes thereof. At the time of navigation, an intersection inspecting section 8 inspects whether a sectional traveling course between two arbitrary points on the optimal course searched at the optimal course searching section 5 exists in the sectional traveling course storing section 7 and extracts that sectional traveling course therefrom if it exists. Based on the optimal course and the extracted sectional traveling course, a navigation course generating section 9 substitutes the sectional traveling course for the section between two points on the optimal course, thus generating a navigation course.
