Abstract: A communication terminal is connected to a server device in a bidirectionally communicable manner and configured to transmit a departure point, a destination, and a route retrieval request from the departure point to the destination to the server device and to acquire a route that is retrieved and delivered by the server device in response to the route retrieval request. The communication terminal receives, from the server device, location road information for identifying a position of a moving object on a map and identifying the position of the moving object based on the received location road information. The communication terminal transmits, to the server device, the route retrieval request in which the identified position of the moving object is set as the departure point, and receives, from the server device, a route that is retrieved by the server device in response to the route retrieval request.

Abstract: To provide a technique for recognizing a tendency of a parking lot that was actually used by users visiting a target facility, a parking lot information management system includes: a parking information collecting unit that collects parking information indicating a parking point at which a vehicle is parked from the vehicle; and a history information accumulating unit that accumulates history information for every target facility that is set as a destination, the history information configured so that a tendency of a parking lot that the vehicle was actually parked in when the target facility was set as the destination is derived, based on the parking information.

Abstract: Driving support systems and programs obtain congestion information specifying any congested link where there is congestion and provide driving support based on the congestion information. The systems and programs determine if the congested link has two or more lanes in each direction and if there is a branch at an end of the congested link, and if the congested link has two or more lanes in each direction and there is a branch at the end of the congested link, determine whether connected links include one or more links where there is congestion and one or more links where there is no congestion. If the connected links include one or more links where there is congestion and one or more links where there is no congestion, the systems and programs determine driving support according to the link onto which a vehicle exits at the branch.

Abstract: A server is connected to a communication terminal and configured to receive a departure point, a destination, and a route retrieval request from the departure point to the destination from the terminal and to deliver a route retrieved in response to the received route retrieval request to the terminal. When the route retrieval request is acquired from the terminal, the server acquires route information related to a target route that is a route corresponding to a predetermined distance from the departure point in a terminal-recommended route that is a route from the departure point to the destination and is retrieved by using terminal-side map information provided in the terminal. The server retrieves a route to the destination that includes at least a part of the target route by using device-side map information provided in the server and the route information, and delivers the retrieved route to the terminal.

Abstract: Route search systems, methods, and programs search for a recommended route using a cost value of a link or a node that constitutes a route. The systems, methods, and programs calculate the cost value of the link or the node on the basis of calculation material information that serves as a material for calculating the cost value, and specify a reliability degree of the calculated cost value of the link or the node on the basis of a number of pieces of the calculation material information used to calculate the cost value of the link or the node. The systems, methods, and programs correct the cost value of the link or the node, the reliability degree of which has been specified, on the basis of the specified reliability degree, and search for the recommended route using the corrected cost value.

Abstract: Route search devices, systems, and programs obtain current traffic information indicating traffic conditions at a present time and obtain statistical traffic information, the statistical traffic information being statistical information obtained by collecting statistics of histories of traffic information. The devices, systems, and programs determine a degree of traffic congestion of a road at the present time, identify travel time for a road whose degree of traffic congestion is greater than or equal to a threshold, based on the current traffic information, and identify travel time for a road whose degree of traffic congestion is less than the threshold, based on the statistical traffic information. The devices, systems, and programs then search for a route to a destination, using the identified travel time.

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: 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: 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: Route search systems, methods, and programs search for a recommended route for transfer with switching between a plurality of transportation modes. The systems, methods, and programs acquire link information for specifying a link for transfer by each of the plurality of transportation modes and connection information related to connection between links for transfer by different transportation modes, and set a condition for switching from a first transportation mode to a second transportation mode, which is different from the first transportation mode, on the basis of a combination of the first transportation mode and the second transportation mode. The systems, methods, and programs search for the recommended route for transfer with switching between the plurality of transportation modes on the basis of the link information, the connection information, and the set condition, the recommended route connecting links for transfer by different transportation modes.
