ABSTRACT:
A navigation apparatus defines the route of movement from the current location to the destination on the basis of map information. It acquires road information relating to characteristics of the current road on which the vehicle is running and those of each of the branch roads extending from the fork located ahead of the current road by way of road information acquiring section21.The acquired road information is collated with the requirement information stored in requirement information storage section22and the number of points correlated with the requirement that is met or not met are added or subtracted, whichever appropriate, to determine the total number of points by the agreement judging section23.If the total number of points is greater than a threshold value, the navigation apparatus judges that the vehicle may not divert from the route of movement and restricts or suppresses guidance for driving the vehicle provided by guidance notification section18.If, on the other hand, the total number of points is smaller than the threshold value, the navigation apparatus judges that the vehicle may divert from the route of movement and allows the guidance notification section18to provide guidance.
