    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： A navigation device divides a pathfinding range into plural areas and performs pathfinding in consideration of congestion information. The navigation device includes a forecast congestion information generating unit configured to generate forecast congestion information corresponding to a predetermined time based on traffic information; and a forecast congestion information applying unit configured to apply, to each of the areas, the forecast congestion information corresponding to a time when a vehicle arrives in each of the areas. The navigation device includes an area setting unit configured to set regions divided by concentric circles centering around a present location, as the plural areas. The radius of the concentric circles is incremented by a fixed length that is set beforehand for each region or each time zone.

    摘要： A navigation system collects life information associated with a user and extracts a life pattern from the collected life information. The navigation system registers the extracted life pattern as life pattern information. The navigation system determines a predicted start time and a predicted destination based on the life pattern information and generates predicted traffic information associated with a geographical area including the destination and associated with a time range including the predicted start time.

    摘要： A navigation system, traffic prediction method, and traffic prediction program search for a plurality of routes to a destination. The system, method, and program calculate, if any of the plurality of routes passes through a predetermined area, a predicted time at which a link within the predetermined area will be passed through. The system, method, and program generate predicted traffic information for the link at the predicted time at which the link will be passed through based on the stored traffic information.

    摘要： A traffic information generation method for generating traffic information for each link includes a vehicle speed detection step of detecting a vehicle speed at predetermined distance intervals or at predetermined time intervals using a vehicle speed sensor; and a traffic jam degree detection step of referring to a specified speed and a specified distance prescribed in association with a traffic jam degree representing a level of a traffic jam and a connection determination distance prescribed in accordance with a road type to detect the traffic jam degree corresponding to the vehicle speed. When a link length falls within a predetermined range, information on the traffic jam degree corresponding to a fastest vehicle speed within a prescribed starting point distance from a beginning of the link is allocated to the link.
