Navigation device, navigation method, and program
First Claim
1. A navigation device, comprising:
- a memory storing a guidance program; and
a processor that, when executing the stored program;
acquires deviated point information regarding a deviated point where a vehicle traveling a set route has deviated the set route;
acquires post-deviation travel history information regarding a travel history, the travel history indicating routes that past deviated vehicles have traveled in the past after having deviated the set route at the deviated point;
determines based on the post-deviation travel history information whether each past deviated vehicle had traveled along a reroute set after deviating the route at the deviated point;
determines whether a percentage of the past deviated vehicles that were determined as having traveled along the reroute is a first predetermined value or more;
when it is determined that the percentage of the past deviated vehicles that were determined as having traveled along the reroute is the first predetermined value or more, determines that guidance of the set route is not appropriate; and
when it is determined that the guidance of the route is not appropriate, changes the guidance of the route.

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.

7. A navigation method comprising:
-
acquiring deviated point information regarding a deviated point where a vehicle traveling a set route has deviated the set route; acquiring post-deviation travel history information regarding a travel history, the travel history indicating routes that past deviated vehicles have traveled in the past after having deviated the set route at the deviated point; determining based on the post-deviation travel history information whether each past deviated vehicle had traveled along a reroute set after deviating the route at the deviated point; determining whether a percentage of the past deviated vehicles that were determined as having traveled along the reroute is a first predetermined value or more; when it has been determined that the percentage of the past deviated vehicles that were determined as having traveled along the reroute is the first predetermined value or more, determining that guidance of the set route is not appropriate; and when it is determined that the guidance of the route is not appropriate, changing the guidance of the route.

8. A non-transitory computer-readable storage medium storing a computer-executable navigation program, the program comprising:
-
instructions for acquiring deviated point information regarding a deviated point where a vehicle traveling a set route has deviated the set route; instructions for acquiring post-deviation travel history information regarding a travel history, the travel history indicating routes that past deviated vehicles have traveled in the past after having deviated the set route at the deviated point; instructions for determining based on the post-deviation travel history information whether each past deviated vehicle had traveled along a reroute set after deviating the route at the deviated point; instructions for determining whether a percentage of the past deviated vehicles that were determined as having traveled along the reroute is a first predetermined value or more; instructions for, when it has been determined that the percentage of the past deviated vehicles that were determined as having traveled along the reroute is the first predetermined value or more, determining that guidance of the set route is not appropriate; and instructions for, when it is determined that the guidance of the route is not appropriate, changing the guidance of the route.
