Abstract
An information distribution center constantly obtains the latest traffic information from a traffic information center. A user registers one or more routes at the information distribution center in advance. A navigation apparatus accesses the information distribution center using a mobile communication device to request distribution of traffic information relating to a route registered at the information distribution center. In response to the request from the navigation apparatus, the information distribution center sends traffic information relating to the relevant route to the navigation apparatus.
