    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 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).

    摘要: There are provided a route searching device, a route searching system, and a computer program that allow to search for a more appropriate route by identifying accurate travel time for a road based on traffic information, without increasing processing load. Specifically, each of current traffic information indicating traffic conditions at the present time and statistical traffic information which is statistical information obtained by collecting statistics of histories of traffic information is obtained, a degree of traffic congestion of a road at the present time is determined, and travel time for a road whose degree of traffic congestion is greater than or equal to a threshold is identified based on the current traffic information, and travel time for a road whose degree of traffic congestion is less than the threshold is identified based on the statistical traffic information. Then, a route search is performed using the identified travel time.
