PROBLEM TO BE SOLVED: To perform guidance to an entrance of a destination and specify and accumulate information on the entrance of the destination from track information on a route from a terminal. SOLUTION: The terminal N transmits travel route data (track information) within a prescribed distance to a destination of a vehicle to a server S with destination information. The server S specifies coordinates of an entrance of a parking lot in a destination facility on the basis of information transmitted from the terminal N, compares the coordinates of the entrance with already registered coordinates (from second coordinates to fourth coordinates) of the entrance in the facility, makes rearrangement sequentially from candidates having a larger specific frequency, and accumulates data. The server S transfers second coordinate information to the terminal N at the reception of a transfer request for the second coordinates from the terminal N. COPYRIGHT: (C)2007,JPO&INPIT
