Abstract: There are provided a communication terminal, a server device, a movement guidance system, and a computer program that can provide movement guidance based on a new version of map information soon after starting up the communication terminal. Specifically, a communication terminal 5 is configured to identify, after its startup, update target areas which are areas whose terminal-side map information 48 included in the communication terminal 5 is an older version of map information than device-side map information 25 included in a server device 3; request the server device 3 for movement guidance information 26 targeted for at least update target areas around a current location, the movement guidance information 26 being used to provide movement guidance for a mobile unit; and provide movement guidance for the mobile unit using movement guidance information 26 transmitted from the server device 3 in response to the request.

Abstract: Movement guidance information for performing traveling guidance for a vehicle is requested to a guidance information delivering server device based on an area update table and an area identification table for managing an update state of map information in a communication terminal, and traveling guidance for the vehicle is performed based on the movement guidance information delivered from the guidance information delivering server device in response to the request.

Abstract: A communication terminal transmits a route search request for a destination to a server device and obtains a route searched from the server device. The terminal requests the server device for guidance information after starting up the communication terminal, the guidance information being used to provide movement guidance for a mobile unit and being targeted for at least an update target area around a current location among update target areas, the update target areas being areas whose terminal-side map information included in the communication terminal is an older version of map information than device-side map information included in the server device. The terminal receives the guidance information transmitted from the server device in response to the request for the guidance information, and provides movement guidance for the mobile unit using a guidance route set on the communication terminal and the received guidance information.

Abstract: 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.

Abstract: A communication terminal is connected to a server and transmits a route search request for a destination to the server and obtains a route searched for from the server according to the request. When setting a destination or transmitting the route search request to the server, the terminal requests the server for guidance information targeted for at least an update target area around a current location among update target areas. The guidance information is for providing movement guidance for a mobile unit, and the update target areas are areas whose terminal-side map information included in the terminal is an older version of map information relative to the server's device-side map information. The terminal receives the guidance information transmitted from the server according to the request for the guidance information, and provides the movement guidance for the mobile unit using a route set on the terminal and the received guidance information.

Abstract: Movement guidance devices and programs provide movement guidance for a mobile unit using guidance information for providing movement guidance for the mobile unit. The guidance information is delivered from a server device. The devices and programs store the guidance information delivered from the server device in a memory. The stored guidance information is area-section-by-area-section guidance information. The devices and programs set a remaining priority for the stored guidance information on a per area section basis of map information and delete, from the memory, guidance information for an area section with a low remaining priority on a priority basis rather than guidance information for an area section with a high remaining priority among the stored guidance information.

Abstract: Vehicle operation diagnosis devices, methods, and programs diagnose a driver's operation of a vehicle based on a vehicle parameter and a driving diagnosis judgment standard that is set for a diagnosis item. The devices, methods, and programs acquire information that pertains to an accident factor for a high-accident location in the vicinity of the vehicle where not less than a specified number of accidents have occurred in the past, modify the driving diagnosis judgment standard based on the accident factor for the high-accident location, in a case where the vehicle is traveling in the high-accident location, and acquire the vehicle parameter. The devices, methods, and programs diagnose the driver's operation of the vehicle based on the modified driving diagnosis judgment standard and the acquired vehicle parameter.

Abstract: Systems, methods, and programs for navigation guide to a destination along a searched route and receive road information and traffic information including traffic congestion information. If according to the received traffic congestion information, traffic congestion is detected on the guidance route, the systems, methods, and programs search a detour route to avoid such congestion. The systems, methods, and programs guide to a destination along the detour route. If traffic congestion which was previously avoided by the detour route is determined to have been eased, the systems, methods, and programs search for a new route and switches guidance from the detour route to the new route.
