Abstract:
1. A navigation apparatus comprising: a storage unit that stores vehicle lane information for a guidance point, including right/left-turn information for each vehicle lane at a guidance point, the left/right-turn information for each vehicle lane being expressed by bit width of the number of vehicle lanes; a determination unit that determines a traveling direction of a vehicle; a detection unit that detects whether or not there is the guidance point in the traveling direction of the vehicle; and a decision unit that decides, when it is detected by the detection unit that there are at least two or more guidance points, a priority order of traveling vehicle-lanes at the next guidance point based on vehicle lane information for the two or more guidance points and the traveling direction of the vehicle, wherein the decision unit decides a priority order of traveling vehicle-lanes at a first guidance point that is a guidance point in the traveling direction of the vehicle, by logical conjunction of a bit value for the first guidance point and a bit value for a second guidance point that is a farther guidance point in the traveling direction of the vehicle.
