    摘要： 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.

    摘要： Provided are a driving support system and a computer program which can provide driving support in view of congestion in each lane even when conventional congestion information that does not include information specifying any congested lane is used. Specifically, congestion information specifying any congested link where there is congestion is obtained. If the congested link is a link with two or more lanes in each direction, there is a branch at the end of the congested link, and links connected to the branch include one or more links where there is congestion and one or more links where there is no congestion, driving support is provided according to the link onto which a vehicle exits at the branch.

    摘要： There are provided a communication terminal, a server device, a movement guidance system, and a computer program that prevent as much as possible the occurrence of an event that after the communication terminal obtains a guided route from the server device, movement guidance based on the guided route is not provided or erroneous guidance. Specifically, a communication terminal 5 identifies 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 relative to device-side map information 25 included in a server device 3, requests the server device 3 for movement guidance information 26 targeted for at least an update target area around a current location, the movement guidance information 26 being for providing movement guidance for a mobile unit, and provides movement guidance for the mobile unit using the movement guidance information 26 transmitted from the server device 3 according to the request.

    摘要： A route guidance system includes: a current position detecting unit; a display condition determination processing unit that determines, for each of pieces of lane data that correspond to a lane list display section set in a forward direction of a vehicle position, whether a display condition for creating a lane list is satisfied, based on the pieces of lane data; a display setting processing unit that sets a piece of the lane data that satisfies the display condition as a display target; and a list display processing unit that displays the lane list based on the piece of the lane data that has been set as the display target. Thus, the piece of the lane data that satisfies the display condition is set as the display target, and the lane list is displayed based on the piece of the lane data that has been set as the display target. Consequently, the size of the lane list can be prevented from becoming too large.

    摘要： A route guidance system includes a current position detection portion, a route search processing means, and a guidance processing means. The guidance processing means includes a branching element computation processing means that computes the number of branching elements from a host vehicle position to a guidance point and a point guidance processing means that executes route guidance based on the computed number of the branching elements. The number of the branching elements from the host vehicle position to the guidance point is computed, and the route guidance is executed based on the computed number of the branching elements, so it is possible to recognize the guidance point simply by counting the number of the branching elements, regardless of the number of traffic signals that exist between the host vehicle position and the guidance point. The driver will not fail to recognize the guidance point.

    摘要： A route search system, a route search method, and a computer program capable of finding a more appropriate route for a user are provided. A probe center 4 collects probe information from vehicles 3 that travel across the country, and a navigation apparatus 2 calculates the link cost of a link on the basis of the probe information in the case where a search for a recommended route is performed (S2). The reliability degree of the calculated link cost is specified on the basis of the number of pieces of the probe information used to calculate the link cost of the link (S3). The value of the link cost, the reliability degree of which has been specified, is corrected on the basis of the specified reliability degree (S6). A search for a recommended route is performed using the corrected value of the link cost (S7).
