    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).

    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： Information specifying a guidance-target point ahead of a host vehicle is obtained; signal group information specifying a signal group whose lighting timing is controlled in an interrelated manner is obtained; and the signal group information is referenced so that guidance pertaining to travel at the guidance-target point is performed at an earlier timing when there is a leading signal of a signal group within a predetermined distance from the guidance-target point on the host vehicle side than when there is no leading signal.

    摘要： A CPU of a navigation device transmits probe information including link traveling information and average vehicle speed information at every predetermined time to an information distribution center. On the other hand, when receiving the probe information, a CPU of the information distribution center reads the road type corresponding to each link ID and user's average vehicle speed during uncongested road traveling from the probe information, and determines the vehicle speed region corresponding to this link ID from a vehicle speed region determination table. Thereafter, the CPU of the information distribution center creates traffic information from this vehicle speed region and the probe information, stores it in a center side traffic information DB and statistically processes traffic information of a certain period to generate a link cost corresponding to a link ID and a time zone of a relevant vehicle speed region of statistical traffic information.
