摘要： The present invention aims to provide a technique that can download traffic information in a more efficient manner, in a navigation system including a traffic information distribution server and a terminal unit. The information distribution server narrows down whereas possible traffic information to that to be used for the processing at the terminal unit before downloading the information to the unit. For example, the traffic information distribution server includes: a traffic information obtaining unit for obtaining traffic information pertaining to a link configuring a route or the periphery of the link (e.g., mesh area including the link), and to a predicted running duration of the link; and a sending unit for downloading the obtained traffic information to the terminal unit. Means for narrowing down the object for download may be possessed by the server or the terminal unit.

摘要： A traffic information display apparatus includes a unit for estimating traffic information relating to a link not included in data sent from a traffic information center. A terminal has a display control unit for changing a display method according to whether or not traffic information received from the information center is estimated data. Thereby traffic information distributed on a real time basis and traffic information statistical data can be displayed to be distinguished from each other, and the user can have a criterion of decision of validity of using the traffic information.

摘要： A traffic information providing system externally acquires traffic information including information relating to the travel time of a link, calculates a travel time for a non-provision link to which no travel time is provided through estimate/complement operation. The estimate/complement operation is carried out with use of travel times, emergencies, travel times of links in the vicinity of the non-provision link, and so on, obtained in the near past. The system stores and statistically processes the externally-acquired traffic information, and also estimates a travel time in the near future. When there is an abnormality in the acquired traffic information, the system deletes the abnormality, regards the information as a non-provision link, calculates a probability distribution of travel times of links, calculates a probability distribution of travel times of the entire route made up of a plurality of links, and also calculates a probability for a specific travel time range.
