    摘要： In a case where a CPU 11 provided in an information distribution center 3 has received a request command for requesting predicted traffic information transmitted from a navigation apparatus 2 as well as vehicle information such as a navigator identifying ID, coordinate data of a vehicle position, or coordinate data of a destination, the CPU 11 searches a basic route based on update-purpose map information 14A, and sets a distribution range serving as a transmission target of traffic information 16A, 16B, and 16C. Then, the CPU 11 generates the predicted traffic information 16C such as congestion prediction information corresponding to the distribution range, extracts the predicted traffic information 16C of each link having a difference in the generated predicted traffic information 16C and the current traffic information 16A, and distributes the extracted predicted traffic information 16C to the navigation apparatus 2 together with a link ID of a corresponding link.

    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.

    摘要： Provided are a server device, a communication terminal, a route retrieval system, and a computer program that are capable of setting a currently optimum guidance route for a moving object. Specifically, when a route retrieval start condition is satisfied, a communication terminal 5 retrieves a route from a departure point to a destination based on terminal-side map information 48 provided in the communication terminal 5, and transmits, to a server device 3, a route retrieval request and route information for identifying a continuous link array corresponding to a predetermined distance from the departure point in a terminal-recommended route that is the retrieved route. When the route retrieval request is received, the server device 3 retrieves a route from the departure point to the destination that includes at least a part of the link array identified by the route information, and delivers the retrieved route to the communication terminal 5.

    摘要： According to the present invention, information which is associated with a motion of a vehicle can be acquired even in the case where no vehicle travels on a road. Motion information, which is associated with the motion of the vehicle on the road where the vehicle traveled, is acquired along with time information. Reference traffic information, which is traffic information on the road at a reference time which is specified by the time information, is acquired from a traffic information providing device which constantly provides the traffic information. A correlation between the motion information and the reference traffic information is specified. Furthermore, estimated motion information, which indicates an estimated motion of the vehicle on the road at an estimate time when the motion is estimated, is acquired based on estimating source traffic information at the estimate time and the correlation, the estimating source traffic information being provided as the traffic information of the estimating source from the traffic information providing device in the case where no motion information is acquired at the estimate time.

    摘要： When a destination is set (S311), a CPU transmits to an information distribution center average vehicle speed information and so on together with a request command (S312) requesting for statistical traffic information. On the other hand, a CPU selects statistical traffic information per vehicle speed range of a predetermined vehicle speed range (S411) for each secondary- mesh to thereby search for a basic route to the destination (S412). Subsequently, the CPU identifies a vehicle speed range for each road type from the average vehicle speed information and a vehicle speed range determination table (S413), selects for each mesh ID of all the secondary meshes through which the basic route passes the statistical traffic information per vehicle speed range corresponding to the vehicle speed range identified for each road type from the statistical traffic information per vehicle speed range classified by road types (S414), and distributes it to a navigation device (S415).
