no. 1 example

[0043] FIG. 1 is a block diagram of a system for renting a taxi according to a first embodiment of the present invention.

[0044] As shown in FIG. 1 , the system according to the first embodiment includes: a portable terminal of a user 1A, a map data server 3 , and a taxi data server 4 .

[0045] The portable terminal 1 is designed to have a function of detecting the current position of the user 1A by GPS (Global Positioning System). More specifically, the portable terminal 1 receives a signal transmitted from the GPS satellite 101 in order to recognize the current position of the user 1A. The portable terminal 1 is constituted by, for example, a cellular phone or a personal digital assistant (PDA).

[0046] A plurality of taxis 2 travel near the user 1A. Each of the taxis 2 has a GPS terminal and a wireless signal transceiver. Each of the taxis 2 receives a signal from the GPS satellite 101 through the GPS terminal to recognize its current location, and when receiving a r...

[0080] FIG. 7 is a block diagram of a system for renting a taxi according to a second embodiment of the present invention.

[0081] Compared with the system according to the first embodiment, the designed system according to the second embodiment further includes: an arrival time calculation server 5 . Parts or assemblies corresponding to those of the first embodiment are denoted by the same reference symbols.

[0082] In the second embodiment, unlike the first embodiment, the estimated arrival time of the taxi 2 to the user 1A is not calculated in the portable terminal, but the arrival time is calculated in the arrival time calculation server 5 provided separately from the portable terminal 1. Calculation. Specifically, the arrival time calculation server 5 receives data representing the current location of the user 1A from the portable terminal 1, and calculates the arrival time based on the received current location of the user 1A and the current location of each taxi 2.

[0093] FIG. 9 shows the relationship between the portable terminal 1 and the network in the third embodiment.

[0094] As shown in FIG. 9 , the designed portable terminal 1 accesses the map data server 3 and the taxi data server 4 through a base station 32 , a cellular network 400 , an Internet service provider (IPS) access point 41 , and the Internet 300 .

[0095] The operation of the system according to the third embodiment is the same as that of the system according to the first embodiment.

[0096] According to the third embodiment, the portable terminal 1 can obtain map data and taxi driver information in real time.

Abstract

A system for hiring a taxi is comprised of a handy terminal (1), a receiver equipped in a taxi (2), and a calculator, characterized in that the handy terminal (1) has functions of detecting a current position of itself through GPS (Global Positioning System), and transmitting a request to the receiver of a taxi (2) located in the vicinity of the handy terminal (1) that the taxi (2) comes to the handy terminal (1), and the calculator calculates an arrival time at which the taxi (2) is expected to arrive at the handy terminal (1), based on the current position of the handy terminal (1) and a current position of the taxi (2).

Description

technical field [0001] The present invention relates to a system for renting a taxi, a portable terminal used in the system, a method for renting a taxi, and a program for causing a computer to execute the method for renting a taxi. Background technique [0002] For example, Japanese Patent Application Laid-Open No. 2002-157689 has proposed a method for calculating the arrival time of a taxi to a location indicated by a user. In this method, the data processor equipped in the taxi company is based on the data representing the user's current location input by the user himself / herself through his / her portable terminal, and the data representing the user's current position including the data that can be passed through the GPS (Global Positioning System) ) to detect the data of the position of the taxi of the wireless transceiver of the current position of the taxi, and calculate the arrival time of the taxi to the position indicated by the user. [0003] However, this method i...
