摘要： A route search apparatus comprises a road information storage part configured to store road information including link information comprised of single link information and composite link information; and a route searcher configured to search a recommended route between two different points using the link information. The single link information includes information regarding an approach link that is a link approaching to a node at one end of a target link, an exit link that is a link exiting from a node at the other end of the target link, and a cost of the target link for entering from the approach link and exiting to the exit link. The composite link information includes information regarding an approach link that is a link approaching to a node at one end of a target link array, an exit link that is a link exiting from a node at the other end of the target link array, and a cost of the target link array for entering from the approach link and exiting to the exit link.

摘要： An analyzer of the invention adequately analyzes a change in road network by using probe information generated with driving of a vehicle. This analyzer determines a traffic amount of vehicles passing through a specified section included in the road network from a plurality of the probe information accumulated over a predetermined period. The analyzer also determines a discontinuity rate, which is a rate of incidents that vehicle locations are discontinuous in the specified section, from the plurality of probe information accumulated over the predetermined period. The analyzer detects a change in the road network, based on a degree of change between traffic amounts in two different periods with respect to the specified section included in the road network and a degree of change between discontinuity rates in the two different periods. The detected change in the road network can be used for survey of the road network.

摘要： A regulation information analysis system determines transit regulations imposed on a target road or intersection to be analyzed based on probe information sent from a plurality of vehicles. An analysis terminal determines if transit regulations are in effect or not by detecting if the probe information indicating a transition that violates a method of transition to be analyzed, such as right/left turn prohibition is present at the target road or intersection. The analysis terminal determines, based on the geometric shape and the like of the target road or intersection, if there is an avoidance factor which a driver would desire to avoid transiting the target rode or intersection. The quantity of the probe information used for determining the presence or absence of the transit regulations is increased if the avoidance factor is found, whereby the determination accuracy is increased while the overall quantity of the probe information is suppressed.

摘要： A road network analysis system detects major changes in a road network based on probe information from a plurality of vehicles. The probe information is tabulated and the change in the amount of traffic is calculated for each road with a predetermined time interval. If a remarkable change in the amount of traffic is detected for a road before and after a specific baseline day, it is determined that a major change in the road network affecting the traffic has occurred in the vicinity of the road, and the road is specified as a change-related road. A path search may be performed between the endpoints of a plurality of change-related roads, and the searched paths that have the most overlap with the searched paths are selected so as to identify the change-related roads which are commonly affected by the same cause and the endpoints thereof.

摘要： A communication terminal is connected to a server and provides movement guidance for a mobile unit based on guidance information delivered from the server. The terminal requests the server for update information for updating area identification information that identifies a section corresponding to an update target area and a section not corresponding to the update target area on a section-by-section basis. The update target area is an area whose terminal-side map information included in the communication terminal is an older version. The terminal updates the area identification information based on the update information transmitted from the server, requests the server for guidance information for providing movement guidance for the mobile unit based on the updated area identification information, and provides the movement guidance for the mobile unit based on the guidance information delivered from the server.
