Abstract
Navigation systems, methods, and programs acquire deviated point information regarding a deviated point where a vehicle traveling a set route has deviated the route, and acquire post-deviation travel history information regarding a travel history after a deviated vehicle has deviated the route at the deviated point. The systems, methods, and programs determine based on the post-deviation travel history information for each of the deviated vehicles whether the deviated vehicle has traveled along a reroute set after deviating the route at the deviated point, and judges whether a rate of the deviated vehicles which were determined as having traveled along the reroute is a first predetermined value or more. If the rate of the deviated vehicles which were determined as having traveled along the reroute is the first predetermined value or more, the systems, methods, and programs determine that guidance of the route is not appropriate.

10. A navigation device, comprising:
-
a deviated point information acquiring unit that acquires deviated point information regarding a deviated point where a vehicle traveling with a route being set has deviated the route; a post-deviation travel history information acquiring unit that acquires post-deviation travel history information regarding a travel history after a deviated vehicle has deviated the route at the deviated point, the deviated vehicle being the vehicle traveling with the route being set and having deviated the route at the deviated point; a travel determining unit that determines based on the post-deviation travel history information for each of the deviated vehicles whether the deviated vehicle has traveled along a reroute set after deviating the route at the deviated point; a reroute travel rate judging unit that judges whether a rate of the deviated vehicles which were determined as having traveled along the reroute among the deviated vehicles is a first predetermined value or more; and a guidance determining unit that, if the reroute travel rate judging unit has judged that the rate of the deviated vehicles which were determined as having traveled along the reroute is the first predetermined value or more, determines that guidance of the route is not appropriate. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A navigation method comprising the steps of:
-
acquiring deviated point information regarding a deviated point where a vehicle traveling with a route being set has deviated the route; acquiring post-deviation travel history information regarding a travel history after a deviated vehicle has deviated the route at the deviated point, the deviated vehicle being the vehicle traveling with the route being set and having deviated the route at the deviated point; determining based on the post-deviation travel history information for each of the deviated vehicles whether the deviated vehicle has traveled along a reroute set after deviating the route at the deviated point; judging whether a rate of the deviated vehicles which were determined as having traveled along the reroute among the deviated vehicles is a first predetermined value or more; and if it has been judged that the rate of the deviated vehicles which were determined as having traveled along the reroute is the first predetermined value or more, determining that guidance of the route is not appropriate.

18. A computer program causing a computer to execute the functions of:
-
acquiring deviated point information regarding a deviated point where a vehicle traveling with a route being set has deviated the route; acquiring post-deviation travel history information regarding a travel history after a deviated vehicle has deviated the route at the deviated point, the deviated vehicle being the vehicle traveling with the route being set and having deviated the route at the deviated point; determining based on the post-deviation travel history information for each of the deviated vehicles whether the deviated vehicle has traveled along a reroute set after deviating the route at the deviated point; judging whether a rate of the deviated vehicles which were determined as having traveled along the reroute among the deviated vehicles is a first predetermined value or more; and if the reroute travel rate judging unit has judged that the rate of the deviated vehicles which were determined as having traveled along the reroute is the first predetermined value or more, determining that guidance of the route is not appropriate.
