Abstract
A route selecting method, a route selecting system, and a recording medium select a route in which a road on which a user has traveled is suitably reflected. A section traveling route generation portion receives a traveling track of a vehicle detected by a current position and traveling track detection portion and an optimum route searched for by an optimum route searching portion, and compares the traveling track and the optimum route, to extract different road sections as section traveling routes. A section traveling route storage portion stores the extracted section traveling route and its attribute information. A crossing section examination portion first examines, in the case of guiding, whether or not the section traveling route taken as a section a part, between two arbitrary points, of the optimum route searched for by the optimum route searching portion exists in the section traveling route storage portion, and extracts the section traveling route from the section traveling route storage portion when the section traveling route does exist. A guiding route generation portion replaces the part, between the two points, of the optimum route with the section traveling route on the basis of the optimum route and the extracted section traveling route to generate a guiding route.
