    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 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.

    摘要： A traffic information notification system for use by a vehicle acquires vehicle travel history data, automatically registers, on the basis of the acquired travel history data, at least one route along which the vehicle usually travels, a time at which the vehicle travels along each of the at least one routes, and traffic information associated with each of the at least one routes. The traffic information system compares current traffic information along a registered route to be traveled provided by a traffic information system with the automatically registered traffic information for that registered route to be traveled, and provides a notification, when the current traffic information is substantially different from the automatically registered traffic information, of the substantially different current traffic information.
