<P>PROBLEM TO BE SOLVED: To highly accurately acquire required time of a non-selected route. <P>SOLUTION: In a navigation management method for managing required time of each route out of a plurality of routes from a departure point up to a destination point, probe data are edited by using a plurality of nodes preset in respective routes and passage time values of the plurality of nodes obtained from another mobile object different from a user's mobile object by which route search is performed. Based on the probe data of the same group as a group of a plurality of continued nodes included in a non-selected route which is a route other than a selected route selected by the user out of the plurality of routes, the moving time of the other mobile object in a route held between the plurality of nodes in the group in the probe data is found out. Virtual moving time of the non-selected route is calculated by using the found moving time of the other mobile object. <P>COPYRIGHT: (C)2013,JPO&INPIT |
