Abstract

A system for hiring a taxi is comprised of a handy terminal, a receiver equipped in a taxi, and a calculator. The handy terminal has functions of detecting a current position of itself through GPS (Global Positioning System), and transmitting a request to the receiver of a taxi located in the vicinity of the handy terminal that the taxi comes to the handy terminal. The calculator calculates an arrival time at which the taxi is expected to arrive at the handy terminal, based on the current position of the handy terminal and a current position of the taxi.

16. The handy terminal as set forth in claim 15, wherein said system further includes a taxi-data server storing therein data relating to said taxi, and wherein said handy terminal has a function of displaying said taxi data transmitted from said taxi-data server.

17. The handy terminal as set forth in claim 16, wherein said handy terminal displays a plurality of said taxi data such that a user of said handy terminal can select a taxi among displayed taxis, based on said plurality of said taxi data.

18. The handy terminal as set forth in claim 16, wherein said handy terminal downloads said taxi data from said taxi-data server thereto through a packet network, a packet network gateway and Internet.

19. The handy terminal as set forth in claim 16, wherein said handy terminal downloads said taxi data from said taxi-data server thereto through a cellular phone network, an access point of an Internet service provider (ISP) and Internet.

20. The handy terminal as set forth in claim 16, further comprising a memory storing data of taxis which other users used to hire, said calculator receiving a current position of a taxi which a user of the handy terminal selects among said taxis, from said taxi-data server, and calculating an arrival time at which said selected taxi is expected to arrive at said handy terminal, based on a current position of said handy terminal and said current position of said taxi.

21. The handy terminal as set forth in claim 15, wherein said handy terminal receives, after transmission of said request to said receiver, at least one of a current position of said handy terminal and a current position of said taxi at real-time.
