1. A road zone assessment device inside a vehicle, the road zone assessment device comprising:
a display; and
a processor configured to, while the vehicle is navigating:
select a first road zone from among multiple first road zones, the selected first road zone being connected with a second road zone on a location-estimating map used for estimating the location of the vehicle, the multiple first road zones representing sections of a first road associated with a vehicle navigation route generated based on a navigation map and overlapping with road links extending from a branching location node, and the second road zone representing a second road different from the first road,
determine whether the vehicle navigation route extends from the selected first road zone to the second road zone,
identify an alternate first road zone connected to the selected first road zone in a direction of a destination location of the vehicle navigation route, the alternate first road zone being associated with the vehicle navigation route,
determine that the alternate first road zone is erroneously associated with the vehicle navigation route based on the selected first road zone being connected with the second road zone and the vehicle navigation route extending from the selected first road zone to the second road zone,
disassociate the alternate first road zone from the navigation route based on the determination that the alternate first road zone is erroneously associated with the vehicle navigation route, and
control the display to display the vehicle navigation route with the alternative first road zone disassociated.
