| 20120245902 | Tunnel Entrance Elevation Specifying Device, Method for Specifying Tunnel Entrance Elevation, Computer Program for Specifying Tunnel Entrance Elevation, and Storage Medium that Stores Computer Program - Systems for automatically specifying a tunnel entrance and methods that accomplish same. One method includes a target entrance selecting step for selecting, from a map data storing portion, a target entrance for specifying an entrance elevation of a tunnel, a target road link assigning step for assigning, from the map data storing portion, a road link, which includes the target entrance, as a target road link, a corrected point extracting step for extracting a certain point as a corrected point, the certain point being located along the target road link and away from the target entrance outwardly of the tunnel by a predetermined distance, a corrected point elevation specifying step for specifying an elevation of the corrected point as a corrected point elevation, and a first target entrance elevation specifying step for specifying the corrected point elevation as a first elevation of the target entrance. | 09-27-2012 |
| 20120136570 | Device and Method for Generating Route Restriction Information of Intersection, Computer Program for Generating Route Restriction Information of Intersection, and Recording Medium for Recording Computer Program - Provided are a device for automatically generating route restriction information of intersections between main roads and narrow streets, and a method therefor. With respect to a specific intersection which is an intersection between a main road and a narrow street, firstly, it is determined to prohibit a right turn and passing through the intersection. Under these conditions, when it is sufficiently confirmed, by using external information, that the right turn and passing through the intersection can be allowed at the specific intersection, the route restriction regarding the direction is released. Probe information and traffic restriction data are used for the external information. | 05-31-2012 |
