Abstract: A curve-shape modeling device that divides multiple sampling points along a route into a linear section, a relaxation curve section and a steady section, and models a curve shape of the route, includes: a curve extraction unit that extracts a curve from the sampling points based on a curvature of the sampling points; a steady section curvature determination unit that determines a curvature of the steady section based on a curvature of sampling points included in an extracted curve; and a curve entry and exit determination unit that sets a predetermined curvature range including the curvature of the steady section, and determines a start point and an end point of the steady section based on the curvature range.

Abstract: A destination recommendation system includes a map database storing facility data, a travel history database storing travel history data, a trip destination determination section, a calculation section, a search section, and an output portion. The trip destination determination section determines plural trip destinations corresponding to a hub position when the number or a frequency of a plurality of visits from the hub position to each of the trip destinations satisfies a predetermined condition. The calculation section calculates a distance or necessary travel time from the hub position to each trip destination, and calculates a mode value of the distance or the necessary travel time. The search section searches for a target facility that is located within a range of the mode value of the distance or the necessary travel time. The output portion outputs the target facility to a user.

Abstract: In a living area data generation section, a road link having the number of times of traveling not less than a predetermined number of times is acquired based on travel history data, and a predetermined area including the road link is determined as a living area. In a user model generation section, based on the travel history data, the number of outings is acquired by necessary time for outing, according to whether the destination is in a living area or non-living area, and model data of user's outing pattern is generated. In a search condition determination section, based on the model data, a facility search range is determined, and a ratio between the numbers of facilities to be searched for from the living area and non-living area is determined as a search condition. In a facility search section, search is conducted for facilities conforming to the condition and to be presented.

Abstract: A navigation apparatus transmits current position information to a server. The server transmits course data to the navigation apparatus; the course data indicates a course that is predicted based on the current position information. The navigation apparatus corrects a subsequently measured current position on the course specified by the course data. The navigation apparatus transmits corrected position information indicating the corrected position to the server. The server distributes map data to the navigation apparatus; the map data corresponds to a specified area containing the corrected position specified by the corrected position information. Based on the received map data, the navigation apparatus displays a map near the corrected position on a screen of a display portion.

Abstract: A curve modeling device includes a curvature calculation unit, a curvature correction unit, and a node information generation unit. The curvature calculation unit calculates a curvature of each sampling point on a route based on location information of each sampling point. The curvature correction unit corrects the curvature at each sampling point and approximates the route by a straight line interval, an arc interval, or a smooth curve interval. The node information generation unit builds a shape model of a curve included in the route by generating node information indicative of a node location on a road corresponding to the route based on the corrected curvature of the sampling point. The curvature correction unit corrects the curvature under a condition that an orientation difference defined by the calculated curvatures maintains a constant value.
