Abstract:
A route guiding apparatus includes a subtraction distance calculating unit 18 for calculating a distance from an entrance of a guidance intersection determined by a route guidance unit 16 to a center of the guidance intersection according to the width of a road going out of the guidance intersection in a direction along a route to define the distance as a subtraction distance, a notification distance calculating unit 19 for subtracting the subtraction distance calculated by the subtraction distance calculating unit from the distance from a current position detected by a current position detecting unit 12 to the center of the guidance intersection determined by the route guidance unit to calculate a notification distance to be notified, and a display unit 20 for displaying the notification distance calculated by the notification distance calculating unit.
