Abstract

A server generates area-specific particular information beforehand, and obtains positional information and route information from a vehicle-mounted navigation apparatus or a vehicle. The server determines particular information to be sent to the vehicle-mounted navigation apparatus or whether a warning is necessary, for each area segment including location indicated by the positional information and/or the route information. The server then distributes necessary particular information or area-specific threshold data. The vehicle-mounted navigation apparatus receives the information from the server, determines whether or not a warning is necessary in the area segment of the present position of the vehicle using the area-specific threshold data, and displays the particular information or the warning.
