Abstract: A navigation system includes a lane information acquiring unit 27 for acquiring both the number of lanes of a road which forms an intersection, and lane information which defines a road branching off from each of the lanes, a lane direction determining unit 28 for determining the direction of each of the lanes on the basis of both the lane information acquired by the lane information acquiring unit, and a road attribute of an incoming road coming into the intersection and a road attribute of an outgoing road extending from the intersection, the road attributes of the incoming and outgoing roads being included in map data acquired by a map data acquiring unit, and a lane information display unit 29 for displaying the direction of each of the lanes determined by the lane direction determining unit with an arrow.

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.

Abstract: A navigation apparatus includes an input unit 53 for inputting a destination and a waypoint, a route searching unit 54 for searching for a route to the destination via the waypoint inputted from the input unit, and a route guidance unit 55 for, in a case in which the route which is searched for by the route searching unit is the one which urges a vehicle to make a U-turn at the waypoint, inhibits execution of rerouting while a predetermined condition is satisfied even if the vehicle has deviated from the route because the vehicle did not make a U-turn at the waypoint.

Abstract: A navigation apparatus includes a route searching unit for searching for a route from a current position of a moving object to a destination or via point based on map information, an intersection extraction unit for extracting information about an intersection that is located forward of the moving object along the route and that is a target for guidance from the map information, an area information extraction unit for extracting plural pieces of area information about areas lying along the route and beyond the intersection from the map information, a comparison unit for comparing specific information included in each piece of area information with information about the destination or via point, and a selection unit for selecting one piece of area information that is to be a target for guidance based on comparison results obtained by the comparison unit among from the plural pieces of area information.
