To provide a system that can provide traffic information to drivers of automobiles or the like with high prediction precision. In a traffic information management system according to the present invention, a first processing unitrecognizes a transition pattern of the necessary travel time for an automobilefor each unit road. A second processing unitrecognizes a route including one or more unit roads by communicating with a navigation system. For each unit road included in the route, a third processing unitsearches for a 'resembling pattern' that resembles a 'reference pattern' from a &#x201c;past pattern&#x201d;. A fourth processing unitpredicts the necessary travel time required for the automobile to travel the route or a unit road included in the route based on the resembling pattern. A communication processing unittransmits traffic information including the predicted necessary travel time to the navigation system

Traffic information management system

A vehicle navigation server for providing traffic information, which is useful and has a suitable data amount, to a vehicle navigation device, so as to make the vehicle have a comfortable travel. The server calculates at least one proposed travel based on input data including a current or start position and a destination of the vehicle, and defines a map mesh consisting of mesh units on the proposed travel route. The server extracts traffic information relating to each mesh unit from a traffic information storage device in turn, where traffic information relating to the mesh unit which includes the start or current position is obtained first. The server monitors a total amount of extracted information, and terminates information extraction for the following mesh units when the total amount becomes equal to or larger than a predetermined value. The server then sends the traffic information to a vehicle navigation device.
