Abstract

A mobile phone base station sends to a mobile phone device information requesting location data thereof, receives location data sent back by the mobile phone device according to the information, and outputs the location data to a location data collection system. The location data collection system inputs the location data, and generates state-of-move information constituted from a location distribution, a moving speed distribution, and a moving direction distribution, or information obtained by filing these information, based on the location data. Then, the location data collection system broadcasts the generated state-of-move information to the car navigation system located in a predetermined area through the mobile phone base station. The car navigation system displays the received state-of-move information on a screen of a display unit thereof with a map indicating the vicinity of the location of the vehicle.
