Description

  The present invention relates to a taxi fare display system configured by connecting a mobile terminal such as a mobile phone terminal and a server device through a communication network. The present invention also relates to a server device constituting the taxi fare display system and a taxi fare display support program for a computer of a portable terminal constituting the taxi fare display system.

  If you are trying to take a taxi and have a small amount of money with you, you may be worried about whether the fare to your destination is sufficient. Proposals for solving such problems are provided in Patent Document 1 (Japanese Patent Laid-Open No. 2007-58345) and Patent Document 2 (Japanese Patent Laid-Open No. 2009-145080).

  In Patent Document 1, a mobile communication device notifies a route notification device of a planned position and a target position for getting on a taxi. Then, the route notification device searches the route based on the map information while referring to the traffic information at the time point, specifies the shortest route from the boarding position to the destination as the optimum route, and uses the optimum route. In this case, the taxi fare is calculated based on the taxi billing information and returned to the portable communication device. The user of the portable communication device can determine whether the taxi can be used with his / her money by looking at the taxi fare.

  Furthermore, in Patent Document 1, after getting on a taxi, the mobile communication device notifies the route notification device of the current position of movement, and the route notification device that receives this notifies the route from the current position to the destination. It is determined whether or not the route is the same as the route for which the taxi fare is obtained. If they are not the same, the route notification device recalculates the taxi fare for the newly specified route. In other words, in Patent Document 1, even if the taxi travels a route different from the planned route due to traffic jams or accidents, the taxi fee is calculated as much as possible by recalculating the taxi fee for the changed route. To be in line with the actual movement.

  Also, in Patent Document 2, as in Patent Document 1, prior to getting on a taxi, an optimal route search from the planned position to get on the taxi to the target position is performed, and the taxi fare on the optimal route is calculated, and the taxi is also calculated. It is disclosed that a point where a fee is added and a fee up to that point are calculated and presented to the user.

  In Patent Document 2, after actually getting on a taxi, for example, when the degree of traffic congestion on the road changes and affects the taxi fare, the route search server is informed by a correction instruction through the operation input means. It is described that the optimum route search is requested again so that the charge to the charge addition point and the destination can be corrected.

JP 2007-58345 A JP 2009-145080 A

  As described above, according to Patent Literature 1 and Patent Literature 2, before getting on a taxi, a route search can be performed to know the taxi fare from the planned boarding location to the destination, and the taxi can actually be used. When boarding, taxi fare will be corrected in response to the occurrence of a route change when a taxi runs on a route different from the result of the route search performed in advance, so even if the amount on hand is small, it can be used as a reference You can get taxi fare information.

  However, as is well known, taxi fare is charged not only for travel distance but also for time. That is, for example, when the traveling speed of a taxi is 10 km / h or less (including stoppage), the taxi fare is charged according to time.

  However, in Patent Document 1 and Patent Document 2 described above, when a taxi travels following exactly the same route as the route searched in advance, the time delay due to actual traffic congestion or the time delay due to signal waiting is not used. The taxi fare provided to the person is not reflected at all. For this reason, the user may not realize that the taxi fare to the destination presented to the user is different from the actual taxi fare, and there is a possibility that the money will be insufficient.

  In view of the above, the present invention considers the taxi fare from the boarding position depending on the situation, not only the route change, but also the time delay due to traffic jams and the time delay due to traffic lights, and depending on the actual taxi driving state An object of the present invention is to provide a taxi fare display system capable of presenting to a user a fare that changes in real time.

In order to solve the above problems, the invention of claim 1

When,
With
Each time the mobile terminal receives the third fee from the server device, the portable terminal updates the taxi fee from the boarding position displayed on the display screen to the destination with the received third fee. A taxi fare display system characterized by

  In invention of Claim 1 of the above-mentioned structure, the information of the boarding position and the destination to a taxi is notified to a server apparatus from a portable terminal. When the user gets on the taxi, the user inputs the boarding notification to the portable terminal. Then, the mobile terminal transmits the current position measured by the position positioning means, for example, at a predetermined time interval through the communication network. The data on the current location of the mobile terminal may be sent directly to the server device, or may be sent to the server device via a device that collects location information of the mobile terminal.

  The server device stores information on the current position of the mobile terminal in the storage unit in association with the transmission time or the reception time. Therefore, the accumulation means stores a point sequence of the current position with the passage of time of the portable terminal. That is, the accumulating means stores the movement trajectory and the movement time of the mobile terminal.

  The server device calculates a first taxi fare from the boarding position to the current position at the notification timing based on the movement locus and movement time of the mobile terminal accumulated in the accumulation means. Further, the server device determines a route between the current position at the notification timing and the designated destination, and calculates the second taxi fare calculated based on the determined route from the boarding position to the current at the notification timing. A third taxi fare from the boarding position to the destination is calculated by adding to the first taxi fare to the position. Then, the server device notifies the calculated third taxi fare to the portable terminal at regular time intervals.

  Each time the mobile terminal receives the third taxi fare from the server device, the mobile terminal updates the taxi fare from the boarding position to the destination displayed on the display screen with the received third taxi fare.

  As described above, according to the first aspect of the present invention, the server device stores the accumulated data of the current position data that is received and accumulated from the user's portable terminal after the user actually gets on the taxi. Based on the above, the first taxi fare from the boarding position to the current position at the notification timing is calculated and calculated according to the actual travel distance and travel time of the taxi. This 1st taxi fare takes into account traffic delays, time delays due to signal waiting, and time delays due to signal waiting, and is almost the same as the fare meter on the taxi that is on board and is accurate. .

  According to the invention of claim 1, the server device adds the second taxi fee calculated based on the route from the current position at the time of notification to the destination to the accurate first taxi fee. By doing so, the third taxi fare from the boarding position to the destination is calculated, so this third taxi fare actually approximates the taxi fare from the boarding position to the destination, and the error is small. Become. In particular, the closer the taxi travel position is to the destination, the closer the taxi fare to the destination is as calculated by an actual taximeter.

  As described above, according to the first aspect of the present invention, as a taxi fare from the boarding position to the destination, not only a route change but also a time delay due to traffic jams at least from the boarding position to the current position at the notification timing. The third taxi fare calculated according to the actual taxi driving state including time delay due to waiting for traffic lights and signals can be presented to the user of the portable terminal.

  Thereby, the user of a portable terminal can know the charge which changes in real time according to the actual taxi driving state from the boarding position to the destination. In addition, the closer to the destination, the higher the accuracy of the third taxi fare, which is very useful information for the user.

The invention of claim 2 is the invention according to claim 1,
The taxi fare transmission means of the server device includes the first taxi fare from the boarding position to the current position at the notification timing in addition to the information on the third taxi fare from the boarding position to the destination. To the mobile device,
The portable terminal displays a first taxi fare from the boarding position to the current position at the notification timing on the display screen in addition to the third taxi fare from the boarding position to the destination. It is characterized by that.

  According to the invention of claim 2, in addition to the third taxi fare from the boarding position to the destination, the first taxi fare from the boarding position to the current position at the notification timing is displayed on the display screen of the portable terminal. Is displayed.

  As described above, the first taxi fare takes into account the time delay due to traffic jams and the time delay due to waiting for traffic lights, and should be almost the same as the fare meter on the taxi on board. Therefore, if there is an error between the taxi fare meter of the taxi that is on board and the first taxi fare, the error is between the calculation at the server device and the calculation at the taxi fare meter. This is considered to be an error that occurred. Therefore, the user of the mobile terminal can more accurately grasp the fee that changes in real time by considering this error for the third taxi fee from the boarding position to the destination.

  According to the present invention, the taxi fare from the boarding position changes in real time according to the actual taxi driving state, not only depending on the route change, but also taking into account the time delay due to traffic jams and the time delay due to waiting for traffic lights. Charges can be presented to users.

  Hereinafter, embodiments of a taxi fare display system according to the present invention will be described with reference to the drawings.

[Overview of embodiment of taxi fare display system; FIG. 1]
FIG. 1 is a diagram showing an overview of an embodiment of a taxi fare display system. As shown in FIG. 1, a taxi fare display system according to this embodiment includes a mobile phone terminal 1 as an example of a mobile terminal and a taxi fare calculation support server (hereinafter simply referred to as a server device) through a communication network 3. 2) (referred to as a server). In this example, the communication network 3 includes a mobile phone network and the Internet.

  A user of the mobile phone terminal 1 obtains a support application program for receiving a taxi fare display service from the server 2 by accessing the server 1 through the Internet included in the communication network 3, and will be described later. You can receive a taxi fare display service with such service contents. Note that a support application program for receiving a taxi fare display service may be installed in advance in each of the mobile phone terminals 1.

  Server 2 provides taxi fare display services by taxi company, by region (by business area), by taxi model (small, medium, large), and by time of use (midnight, normal time) There is a separate fee structure table. The taxi fare display service in the server 2 in this embodiment includes a service before boarding a taxi and a service after actually boarding a taxi. The object of the present invention relates to a service after actually getting on a taxi.

  When a user intends to receive a service before boarding a taxi, the user accesses the server 2 from the mobile phone terminal 1 and stores at least the taxi boarding destination and destination in the server 2. Notice. In this case, if necessary, the user notifies the taxi company and taxi model together.

  Upon receiving this notification, the server 2 obtains traffic information such as traffic conditions and accident occurrence information at that time from the traffic information providing site through the Internet, and refers to it, while notifying the scheduled boarding location and purpose The optimum route for taxi movement to and from the ground is found in the route search. Then, a taxi fare is calculated and calculated for the obtained optimum route and notified to the user of the accessed mobile phone terminal 1. In this case, when the taxi company name and vehicle type are specified, the taxi fare is calculated with the specified taxi company name and vehicle type. When the taxi company name is not specified, the specific taxi company's specific taxi company Calculate taxi fare for vehicle type, for example medium size. Then, the server 2 notifies the mobile phone terminal 1 of the taxi company name and vehicle type when the taxi fare is calculated.

  The cellular phone terminal 1 displays the taxi fare provided from the server 2 on the display screen together with the taxi company name and the taxi model. The user of the mobile phone terminal 1 can know the approximate taxi fare from the boarding place to the destination by looking at the displayed taxi fare.

  When the user of the cellular phone terminal 1 gets in an actual taxi, at the start of the ride, the user notifies the server 2 of the destination, the company name of the taxi that has been boarded, and the type of the taxi. The server 2 is notified of the start of boarding. At this time, the mobile phone terminal 1 measures the current position where the taxi boarding start is notified, and notifies the server 2 of the current position data together with information on the time. Then, the cellular phone terminal 1 transmits the current position data measured by the cellular phone terminal 1 to the server 2 at a predetermined time interval, for example, every 20 seconds, according to the taxi fare display service support application program.

  When the server 2 receives a taxi boarding start notification from the mobile phone terminal 1, the server 2 determines that the user of the mobile phone terminal 1 has taken a taxi, and uses the current location data sent at the same time as the boarding location data. Is stored in association with the reception time. Then, the server 2 acquires traffic information such as traffic conditions and accident occurrence information at that time from the Internet, and refers to it to determine the optimum route for taxi movement from the boarding position received from the mobile phone terminal to the destination. Ask for route search. The calculated optimal route is calculated by calculating the taxi fare according to the taxi company name and vehicle type received from the mobile phone terminal, and notified to the user of the mobile phone terminal 1 who has accessed.

  Then, the server 2 sequentially stores the current position data of the mobile phone terminal 1 sent at predetermined time intervals after the start of taxi boarding in association with the information of the reception time. The server 2 can detect the actual travel route and travel time of the taxi on which the user of the mobile phone terminal 1 gets from the current position data and the reception time sequentially sent from the mobile phone terminal 1. it can.

  Then, the server 2 detects a timing point at which the taxi fare increases from the detected travel distance and travel time of the travel route and a calculation rule as a reference for calculating the taxi fare, and this timing point is determined as the mobile phone terminal. It is set as the notification timing point to notify the user 1 of the updated taxi fare.

  The taxi fare is determined based on the distance traveled when the taxi is moving at a speed higher than a predetermined speed. The taxi fare is determined by the elapsed time when the taxi moving speed is lower than the predetermined speed. Based on this, the timing for increasing the taxi fare is determined.

  The server 2 calculates the moving speed of the taxi from the detected moving distance and moving time of the moving route, and monitors the elapsed time. When the time for increasing the taxi fare is reached, this time is set as the notification timing. Then, the server 2 calculates the taxi fare Cm from the boarding position to the notification timing from the movement distance and the movement time of the movement route that can be detected based on the accumulated data. Then, the mobile phone terminal 1 is notified of the taxi fare Cm from the calculated boarding position to the notification timing.

  The taxi fare Cm is based on the travel route and travel time of the point sequence of the current position notified from the mobile phone terminal 1 to the server 2 at predetermined time intervals. It corresponds to the travel time, and is the same as the taxi fare displayed on the taxi meter mounted on the taxi or with a slight error.

  Further, the server 2 searches for a route from the current position at the time of notification to the destination, and calculates a taxi fare Ct when the taxi travels according to the route of the search result. Then, by adding the taxi fare Ct when moving continuously from the current position at the time of change to the destination to the taxi fare Cm from the boarding position already determined to the time of the change, Calculate the taxi fare Co (= Cm + Ct) to the ground. Then, the server 2 calculates the taxi fee Co from the boarding position to the destination as a result of the calculation, the taxi fee Cm from the boarding position to the current position at the notification timing, and the taxi fee Ct from the current position to the destination. Are transmitted to the mobile phone terminal 1.

  Note that when the current position at the notification timing is on the route as a result of the previous route search, the server 2 does not perform a new route search, but changes the timing along the route of the route search result. You may make it calculate the taxi fare Ct when moving from the current position at the time to the destination continuously.

  The cellular phone terminal 1 receives the taxi fees Co, Cm, and Ct information from the server 2 and displays the taxi fees Co, Cm, and Ct side by side. As a result, the user of the mobile phone terminal 1 can obtain the taxi fare Cm from the boarding position to the current position at the notification timing and the current position at the notification timing to the destination in addition to the taxi fare Co from the boarding position to the destination. You can refer to the taxi fare Ct.

  The server 2 recalculates the taxi fares Cm, Ct and Co every time the taxi fares are notified, and notifies the mobile phone terminal 1 of the taxi fares Cm, Ct and Co as a result of the recalculation.

  In this case, the taxi fare Cm from the boarding position to the current position at the notification timing corresponds to the travel locus and travel time when the taxi actually traveled, as described above, and is used for traffic jams and signal waiting. Such time is also added in real time depending on the situation. Therefore, this taxi fare Cm is the same or similar to the taxi fare displayed on the taxi meter mounted on the taxi being boarded. The taxi fare Co from the boarding position to the destination is obtained by adding the taxi fare Ct, which is an estimated value of the fare from the current position to the destination at this time, to the taxi fare Cm. Compared to the taxi fare calculated when searching for the route from the position to the destination, the fare is closer to the taxi fare displayed on the taximeter, and the closer to the destination, the higher the degree of approximation.

  Therefore, the user of the mobile phone terminal 1 can make a taxi fare Cm from the boarding position to the current position at the notification timing, a taxi fare Co from the boarding position to the destination, and a taxi from the current position to the destination at the notification timing. By relying on the charge Ct, it is possible to effectively use a taxi while considering the amount of money on hand.

  In this embodiment, the taxi fare Cm from the boarding position to the current position at the notification timing is displayed together with the taxi fare Co from the boarding position to the destination. As described above, this fare Cm should be substantially equal to the taxi fare displayed on the taxi meter mounted on the taxi currently on board. If there is a difference, it can be determined that this is an error between the calculation at the server 2 and the calculation at the taximeter. Therefore, the taxi fare Co displayed as the fare from the boarding position to the destination can be estimated by taking the above error into account, and the taxi fare from the actual boarding position to the destination can be estimated by the taxi meter. It becomes. This estimated fee is a fee that approximates the taxi fee displayed on the taxi meter, and the user can use the taxi more safely.

  Hereinafter, detailed configurations and processing operations of the mobile phone terminal 1 and the server 2 will be further described.

  The touch panel interface 106 sends an operation detection signal corresponding to an operation instruction input by the user through the touch panel 114 to the control unit 101 through the system bus 100. The control unit 101 detects what operation input has been made by the user from the operation detection signal received from the touch panel interface 106, and performs control processing according to the detection result.

  The GPS positioning unit 107 receives radio waves from GPS satellites, measures and detects the current position of the mobile phone terminal 1, and detects the data (latitude, longitude, height data) of the detected current position in the system bus. 100 to the control unit 101. The control unit 101 uses the wireless communication circuit unit 102 to transmit the current position data of the mobile phone terminal 1 to the server 2 via the base station of the mobile phone network.

  The memory 108 is a storage unit for various data used in the mobile phone terminal 1. In this embodiment, the memory 108 includes a storage area for application programs and the like, although not shown.

[Hardware configuration example of server 2]
FIG. 3 is a diagram showing a hardware configuration example of the server 2 in the system according to the embodiment of the present invention. In this example, as shown in FIG. 3, a control unit 201 constituted by a computer transmits a communication interface 202, a transmission / reception processing unit 203, a route search unit 204, a movement locus storage unit 205, a destination fee calculation through a system bus 200. Unit 206, current position fee calculation unit 207, map database 208, route search database 209, taxi fare system table storage unit 210, taxi meter information storage unit 211, notification timing determination unit 212, regional taxi company database 213, clock unit 214 Connected with each of the.

  The control unit 201 is for controlling various processes in the server 2. In this embodiment, the control unit 201 controls various processes such as reception processing of current position data from the mobile phone terminal 1, calculation of taxi fare to be notified to the mobile phone terminal 1, and transmission processing.

  The communication interface 202 is for connecting the server 2 to the communication network 3. Further, the transmission / reception processing unit 203 analyzes information received through the communication interface 202, transfers the information to each necessary unit through the system bus 200, and generates transmission information to be transmitted to the communication network 3 according to the control of the control unit 201. Then, the data is transferred to the communication interface 202.

  The map database 208 stores map information for Japan. The route search database 209 is used together with the map information of Japan stored in the map database 208 to store information for searching for a route between the designated departure place and destination.

  The route search unit 204 refers to the map database 208 and the route search database 209 and performs route search by taxi based on the departure place and destination received from the mobile phone terminal 1. In this example, although not shown in FIG. 1, the route search unit 204 accesses a traffic information providing site connected to the communication network and refers to traffic information and accident information at the time of the search while searching for a route. Execute.

  The movement trajectory accumulating unit 205 associates the current position data sent from the mobile phone terminal 1 through the communication network 3 with the reception time in this example from the taxi boarding position designated by the mobile phone terminal 1. It accumulates sequentially until the ground. In other words, the travel locus storage unit 205 records the travel locus and travel time of the taxi from when the user of the mobile phone terminal 1 gets on the taxi until the user arrives at the destination.

  In this case, in this embodiment, the server 2 calculates the current position using a DGPS (Differential GPS) method using error information of GPS positioning in the base station of the mobile phone network, thereby achieving higher accuracy. In addition, the current position of the mobile phone terminal 1 is obtained.

  The current position fee calculation unit 206 is from the boarding position where the user of the mobile phone terminal 1 accumulated in the movement trajectory accumulation unit 205 gets on the taxi to the current position of the mobile phone terminal 1 at the notification timing of notifying the taxi fee. Calculate the taxi fare Ct. At the time of this calculation, the current position fee calculation unit 206 refers to a taxi fee system table that is reference information for calculating the taxi fee stored in the taxi fee system table storage unit 210.

  In this example, the taxi fee system table storage unit 210 stores a fee system table for each taxi company. As described above, the taxi fare differs depending on the vehicle type, and the additional fee is determined based on the addition condition determined by the travel time and the travel time. Also, the taxi fare varies depending on whether the usage hours are late night or other normal times. In addition, taxi fare may vary by business area. The taxi fare system table stores information for calculating the taxi fare according to them.

  FIG. 4 is an example of a taxi fare system table stored in the taxi fare system table storage unit 210, and the table in this example is a taxi fare table for each taxi company. In other words, in the taxi fare system table of this example, information on taxi fare by usage time zone is stored for each business area and vehicle type (small, medium, large) for each taxi company.

  Since taxis in Japan have business areas stipulated by law, the taxi fare system table in this example stores business areas assigned to taxi companies. For each type of taxi, information on the initial ride fee and addition conditions for determining the additional fee are stored as taxi fee information. For example, when the traveling speed of the taxi is 10 km / h or more, the addition condition is a reference traveling distance to which the charge is added and a charge to be added, and when the traveling speed of the taxi is less than 10 km / h, the reference for adding the charge The elapsed time and the charge to be added.

  At the boarding position point where the user of the mobile phone terminal 1 has notified the server 2 of the start of taxi boarding, the current position point is the same as the boarding position point, and no movement track data exists in the movement track storage unit 205. For this purpose, the current position fee calculation unit 206 is determined by the taxi company, the region (business area), the vehicle type, and the usage time zone with reference to the taxi fee system table stored in the taxi fee system table storage unit 210. The initial boarding fee is output as a fee Cm at the current position (boarding position).

  When the taxi on board starts moving, the current position fee calculation unit 206 accumulates the taxi movement trajectory data in the movement trajectory accumulation unit 205, and therefore accumulates in the movement trajectory accumulation unit 205 at the notification timing. Based on the travel trajectory and travel time, a taxi fare Cm that changes in real time according to the actual taxi travel status from the boarding position to the current position at the notification timing is calculated.

  The destination fee calculation unit 207 stores the taxi fee from the boarding position where the user of the mobile phone terminal 1 gets in the taxi to the destination specified by the user in the taxi fee system table storage unit 210. Calculate with reference to the taxi fare system table. The destination fee calculation unit 207 calculates a taxi fee from the boarding position to the destination using the search result of the route search unit 204 and the calculation result of the current position fee calculation unit 206.

  In other words, the destination fee calculation unit 207 determines the fee from the boarding position at which the user of the mobile phone terminal 1 has notified the server 2 of the taxi boarding start to the current position at the notification timing as the current position fee calculation unit 206. The charge Cm of the calculation result is used. The charge from the current location at the notification timing to the designated destination is, if necessary, sent to the route search unit 204 with the current location at the notification timing as the departure location. The route to the destination is specified, the route from the current position at the time of the notification to the designated destination is specified, and the fare Ct when the taxi travels along that route (not including the initial ride fee) calculate. Then, the destination charge calculation unit 207 calculates the charge Co from the boarding position to the destination by adding the charge Cm and the charge Ct.

  That is, at the boarding position point where the user of the mobile phone terminal 1 has notified the server 2 of the taxi boarding start, the boarding position point is the current position at the time of the notification timing. As a starting point, the route search unit 204 searches for a route to the destination designated by the user, and calculates a fee when the taxi moves along the route search result as a fee Ct. Then, the charge Co from the boarding position to the destination is calculated by adding the charge Ct from the current position to the destination to the charge Cm at the current position consisting of the initial boarding charge obtained from the current position charge calculation unit 206. calculate.

  When the current position at the notification timing is not the boarding position, the destination fee calculation unit 207 specifies the route to the designated destination with the current position at the notification timing as the departure point, and A fee when the taxi moves along the specified route is calculated as a fee Ct. Then, by adding the charge Ct from the boarding position to the destination to the charge Cm from the boarding position to the current position at the notification timing obtained from the current position charge calculation unit 206, the boarding position to the destination is added. The charge Co is calculated.

  In this case, as a method for specifying the route from the current position at the notification timing to the destination, in this embodiment, the route search unit 204 searches the route to the destination using the current position at the notification timing as the departure point. Is used each time, and the method of specifying is used. This is because the route search unit 204 performs route search according to traffic information that changes from time to time, and can always select an appropriate route.

  However, for example, when the current position at the notification timing is a position on the route of the previous route search result, the remaining route from the current position at the notification timing to the destination in the previous route search result is used as it is. In addition, when the current position at the notification timing is not a position on the route of the previous route search result, the route to the destination is searched using the current position at the notification timing at that time as the departure point. You may make it make the part 204 search again.

  Next, the taxi meter information storage unit 211 stores correspondence information between the taxi companies used for each taxi company and the feature that allows the timing of the increase in the taxi fare to be monitored from the outside.

  There are several taximeter manufacturing companies in Japan, and it is common for each taxi company to determine which company the taximeters installed in the taxi are made. And many taximeters are equipped with the timing display part which can monitor the increase timing of the display charge from the outside. For example, a taxi meter TA manufactured by Company A says, “The charges that are displayed after three lamps are turned off in sequence and all are turned off, and after running XX meters or xx seconds later. It has a timing display section that says “I will go up”. Also, taxi meter TB manufactured by Company B says, “When the blinking cycle of the blinking lamp is less than the predetermined number of seconds, the fare that is displayed after running XX meters or □□ seconds from that point onwards. It has a timing display section that says “I will go up”.

  If the taxi user knows the feature that can monitor the increase timing of the taxi meter display fee from the outside, by monitoring it, the taxi can stop and get off before the taxi fee increases. It is possible and convenient. The taximeter information storage unit 211 stores information for that purpose.

  FIG. 5 shows an example of taximeter information stored in the taximeter information storage unit 211. That is, as shown in FIG. 5, the taximeter information storage unit 211 stores taximeters TA, TB,... For each manufacturing company, and each taximeter TA, TB,. In addition, the name of the taxi company that uses it is recorded, and the timing for increasing the taxi fare for each taximeter TA, TB... Can be monitored from the outside. The feature of the part (hereinafter referred to as the feature of the timing display part of the taximeter) is recorded.

  In this embodiment, when the user of the mobile phone terminal 1 takes a taxi and notifies the server 2 of the taxi company name, the server 2 uses the taxi meter used by the taxi company. The determination is made based on the information stored in the taximeter information storage unit 211. And the characteristic of the timing display part of the determined taximeter is read from the taximeter information storage part 211, it is notified to the mobile telephone terminal 1, and it uses for a user's flight.

  The notification timing determination unit 212 is a function processing unit that determines the increase timing of the taxi fare according to the taxing fee charging rules after the user gets on the taxi. The notification timing determination unit 212 is based on taxi fare charging rule information, travel distance and travel time information from the boarding position stored in the travel trajectory storage unit 205, and time information provided from the clock unit 214. The notification timing point is determined as the predicted increase timing point of the taxi fare during the ride by the user.

  Note that the notification timing determination unit 212 does not necessarily require the user to make a determination according to the predicted increase timing of the taxi fare during the ride, as in this embodiment. Since it is only necessary to be able to notify the increase, it is needless to say that every predetermined time is set as the notification timing.

  The taxi company database 213 for each region stores information on taxi companies in business areas throughout Japan. FIG. 6 is an example of an area-specific taxi company table in which each of the business areas stored in the area-specific taxi company database 213 and the correspondence of the taxi company to which the business area is assigned are stored.

  This regional taxi company table stores, for each business area, the area information included in the business area and the name of the taxi company to which the business area is assigned. In this embodiment, when the mobile phone terminal 1 requests the server 2 to search for the boarding position as search information, the server 2 refers to the taxi company table for each area in the taxi company database 213 for each area, and determines the boarding position as a business area. It has a function of searching for a taxi company within and creating a list of the taxi companies and providing the list to the mobile phone terminal 1.

  The clock unit 214 provides time information of year / month / day / hour / minute / second. As described above, the time information from the clock unit 214 is used for determining the notification timing point in the notification timing determination unit 212. In addition, the time information when determining the taxi use time zone and the movement track accumulation are used. Also used as reception time information of the current position information stored in the unit 205.

  In the hardware configuration of the server 2 in FIG. 3, the transmission / reception processing unit 203, the route search unit 204, the current location fee calculation unit 206, the destination fee calculation unit 207, and the notification timing determination unit 212 are each controlled by the control unit 201. It can be configured as a software processing function.

[Taxi fee display before user takes taxi]
The user accesses the server 2 by selecting, for example, a bookmark on the mobile phone terminal 1 or a taxi fare display on the application service menu. Then, a support application program for taxi fare service stored in the memory 108 of the mobile phone terminal 1 is activated. Then, the server 2 receives the access of the mobile phone terminal 1 and sends the information on the input screen for information necessary for calculating the taxi fare to the mobile phone terminal 1. 7 is displayed on the display screen 113D of the display 113.

  As information necessary for calculating the taxi fare, as shown in FIG. 7, the boarding position, destination, taxi company name, taxi car type, and the input fields 301, 302, 303, 304 are displayed on the display screen. Is done. In the mobile phone terminal 1, the use time zone display field 305 indicates that the time at that time is based on time information from the clock unit (not shown) of the mobile phone terminal 1, and the time at that time is a normal charge. It is determined whether it is a time zone or a midnight time zone of a special fee, and according to the determination result, it is displayed so as to be able to identify which time zone is a usage time zone. In the example of FIG. 7, the use time zone at that time is shown with a halftone dot.

  In the boarding position input field 301, the user can directly input the boarding position and the place name, and can select “current position”. When the current position is selected, the current position information measured by the GPS positioning unit 107 of the mobile phone terminal 1 is sent to the server 2 as a boarding position.

  In the destination input field 302, the user directly inputs the place name of the destination. A taxi company name is entered in the taxi company input field 303. When a predetermined operation is performed on the input field 303, a list of taxi company names is displayed as a pull-down menu, for example, and the user can select and input the taxi company name from the list. Further, when the icon button 306 of “ride at current location” is operated by the user, a list of only taxi companies having the current location within the business area is displayed as, for example, a pull-down menu, from which the user can select a taxi company. A name can be selected and input.

  When a predetermined operation is performed in the taxi car type input field 304, a taxi car type, that is, a list of three types of cars, that is, a small model, a medium model, and a large model, is displayed as a pull-down menu, for example. Selective input is possible.

  When the user completes the input of information necessary for calculating the taxi fare and operates the “charge calculation” icon 307 on the display screen 113D, the control unit 101 of the mobile phone terminal 1 is input. The taxi fare calculation request is sent to the server 2 including necessary information. When the user operates the “stop” icon 308 on the display screen 113D, the mobile phone terminal 1 sends an instruction to stop the taxi fare calculation service to the server 2 and ends the support application program.

  Then, the server 2 uses the route search unit 204 to search for the optimum route of the travel route by taxi from the designated boarding position to the destination. Then, the destination fee calculation unit 207 of the server 2 calculates the taxi fee on the optimum route of the search result in consideration of the use time zone, taxi company, and taxi model. Then, the server 2 returns the calculation result to the mobile phone terminal 1.

  When the support application program of the cellular phone terminal 1 receives the taxi fare answer from the server 2, the taxi fare display field 310 is provided on the display screen 113D of the display 113 as shown in FIG. The received taxi fare is displayed in this display field 310. At this time, instead of the “charge calculation” icon 307 in FIG. 7, the “boarding start” icon 311 is displayed on the display screen 113D.

[Taxi fare display after the user actually takes a taxi]
The “boarding start” icon 311 is operated by the user when actually getting on a taxi. Prior to operating this “start boarding” icon 311, when the taxi actually boarded differs from the taxi company name or vehicle type selected and designated in advance, in the input field 303 and the input field 304, Re-specify taxi company name and vehicle type. At this time, by operating the “Boarding at current location” icon button 306, only a taxi company whose current location is within the business area is listed, and used to select the taxi company name of the taxi to ride from the list. it can.

  Then, when the user actually gets in the taxi, the user inputs the company name and vehicle type of the taxi in which the user has boarded, and operates the “start boarding” icon 311, the support application program of the mobile phone terminal 1 actually Notify that you have taken a taxi. The notification that the user has actually taken a taxi includes the current position as the boarding position, the destination designated and input by the user, the name of the taxi company, and the vehicle type. Moreover, the time of actual boarding is included as information on the use time zone. Note that this usage time zone information is not included in the notification information from the mobile phone terminal 1 when the server 2 is determined from the time when the notification of “ride” is received. May be.

  When the server 2 receives the notification that the user has actually boarded a taxi from the mobile phone terminal 1, the route search unit 204 searches the route search unit 204 for the optimal route for the taxi from the current position to the destination as the boarding position. To do. Then, as described above, the server 2 determines the taxi fare from the boarding position at the current position fee calculation unit 206 to the current position at the notification timing, and from the boarding position to the destination at the destination fee calculation unit 207. The calculation of the taxi fare is started, and the calculation of the taxi fare is repeated to the destination at each notification timing.

  In addition, when the server 2 receives the notification that the user has actually taken a taxi from the mobile phone terminal 1, the server 2 refers to the taximeter information storage unit 211 based on the taxi company name information included in the notification. The mounted taximeter is determined, and the characteristics of the timing display unit that can monitor the increase timing of the display fee of the taximeter from the outside are sent to the mobile phone terminal 1.

  As shown in FIG. 8B, the support application program of the mobile phone terminal 1 displays the taxi fare to the destination received from the server 2 in the display field 321 of the display screen 113D of the display 113 and the current position. The taxi fare from the current position to the destination is further displayed in the display column 323. Further, the support application program displays in the display column 324 the characteristics of the timing display unit of the taxi meter of the taxi that has been boarded, received from the server 2.

  The user knows the taxi fare from the boarding position where he actually boarded the taxi to the destination by referring to the taxi fare from the boarding position to the current position by referring to the display content of the display screen 113D of FIG. 8B. Can be obtained. In this case, as described above, the taxi fare from the boarding position to the current position is almost the same as the real-time taxi meter display charge based on the actual travel route and travel time of the taxi that was boarded. It should be. Therefore, the user reflects the difference between the taxi meter display charge and the display charge in the display column 322 by adding or subtracting it to the taxi charge up to the destination by means of mental calculation to reflect the taxi charge to the more accurate destination. Can be known.

  However, in this embodiment, the user does not have to add / subtract by such mental arithmetic. That is, the cellular phone terminal of this embodiment matches the taxi fare from the boarding position displayed in the display field 322 to the current position with the taxi meter display price by the user operating the touch panel 114. It is configured so that it can be changed.

  Then, when the user corrects the charge from the boarding position displayed in the display field 322 to the current position, the mobile phone terminal 1 determines the difference ΔCm between the charge Cm before the correction and the charge Cma after the correction. The difference ΔCm is added to the charge Co from the boarding position to the destination, and the charge in the display field 321 is changed and corrected to Co ′.

  Further, when the charge in the display field 322 is corrected and changed, the mobile phone terminal 1 sends a difference ΔCm between the charge Cm before the correction and the charge Cma after the correction to the server 2. The server 2 holds the received difference ΔCm in the current position fee calculation unit 207. When the current position fee calculation unit 206 subsequently calculates the taxi fee from the boarding position to the current position at the notification timing, after correcting the calculated taxi fee Cm using the difference ΔCm, the mobile phone terminal Send to 1. Thereby, thereafter, the taxi fare Cm from the boarding position sent from the server 2 to the mobile phone terminal 1 to the current position at the notification timing reflects the error with the taxi meter.

  Note that the mobile phone terminal 1 may send the corrected taxi fee Cma instead of sending the difference ΔCm to the server 2. In that case, the server 2 calculates the difference ΔCm between the taxi fare Cm calculated by the current location fee calculation unit 207 and the received taxi fare Cma, and holds it in the current location fee calculation unit 206. To.

  In the above example, the mobile phone terminal 1 corrects the taxi fare from the boarding position to the destination by the mobile phone terminal 1 itself in accordance with the correction of the taxi fare Cm from the boarding position to the current position. I made it. However, the corrected taxi fare Cma is sent from the mobile phone terminal 1 to the server 2 to cause the server 2 to correct the taxi fare from the boarding position to the destination, and from the corrected boarding position to the destination. Of course, the cellular phone terminal 1 may be configured to acquire the taxi fare from the server 2 and display it in the display field 321.

  As described above, in this embodiment, the taxi fare from the boarding position to the destination in the display column 321 of the mobile phone terminal 1 is based on the fare Cma corrected to match the taxi meter fare. The taxi fare will be accurately reflected.

  In this embodiment, in addition to displaying the taxi fare as described above, the display screen 113D of the mobile phone terminal 1 displays the characteristics of the timing display unit of the taximeter. Therefore, the user can monitor the timing at which the taxi meter display fee of the taxi on board rises from the characteristics of the taxi meter timing display unit displayed on the display screen 113D of the mobile phone terminal 1. You can get off the taxi before the taxi meter display fee goes up.

[Processing for taxi fare display]
An example of the flow of processing operations for performing taxi fare display as described above will be described below.

<Mobile phone terminal 1>
First, the flow of processing operations performed by the support application program of the mobile phone terminal 1 will be described with reference to FIGS. Since the support application program is executed by the control unit 101, the main body of each process described below is the control unit 101.

  When accessing the server 2, the control unit 101 activates the support application program and starts processing from the start of FIG. The control unit 101 first displays an input screen as shown in FIG. 7 in order to receive input of information necessary for calculating the taxi fare from the boarding position specified by the user to the destination. (Step S1).

  And the control part 101 receives the input of information required for calculation of taxi fare, such as a boarding position, a destination, a taxi company, a vehicle type, and a use time zone (step S2). Next, the control unit 101 determines whether or not the “charge calculation” icon 307 (see FIG. 7) has been pressed (step S3), and determines that the “charge calculation” icon 307 has not been pressed. If so, it is determined whether or not the “stop” icon 308 (see FIG. 7) has been pressed (step S4).

  When it is determined in step S4 that the “stop” icon 308 has not been pressed, the control unit 101 returns the process to step S3 and repeats the processes after step S3. If it is determined in step S4 that the “stop” icon 308 has been pressed, the control unit 101 notifies the server 2 of the stop (step S10), and then ends this processing routine.

  When it is determined in step S3 that the “calculation of charge” icon 307 has been pressed, the control unit 101 provides the server 2 with designation information such as a boarding position, a destination, a taxi company, a vehicle type, and a usage time zone. Then, it is sent in correspondence with the identification information of the mobile phone terminal 1 (for example, the phone number of the mobile phone), and a calculation of the taxi fare from the specified boarding position to the destination is requested (step S5).

  Next, the control unit 101 receives the taxi fare from the boarding position to the destination sent from the server 2, and displays the taxi fare in the display column 310 as shown in FIG. (Step S6).

  Next, the control unit 101 determines whether or not the “stop” icon 308 (see FIG. 8A) has been pressed (step S7). 2 is notified of the cancellation (step S10), and then this processing routine is terminated. When it is determined that the “stop” icon 308 has not been pressed, the control unit 101 receives an input of a taxi company name and a vehicle type (step S8).

  Then, the control unit 101 determines whether or not the “boarding” icon 311 (see FIG. 8A) has been pressed (step S9). If it is determined in step S9 that the “boarding start” icon 311 has not been pressed, the control unit 101 returns the process to step S4, and repeats the processes after step S4. Further, when it is determined in this step S9 that the “boarding start” icon 311 is pressed, the control unit 101 designates the current position measured by the GPS positioning unit 107 as the boarding position where the user actually got on the taxi. The server 2 is notified in association with the identification information of the mobile phone terminal 1 including the destination, taxi company name, vehicle type, and boarding time (step S11 in FIG. 10).

  Next, the control unit 101 receives the taxi fare Co from the boarding position to the destination sent from the server 2 and displays it in the display field 321 of the display screen 113D of the display 113 (FIG. 8 ( B)). At this time, since the server 2 sends the initial ride fee according to the taxi company and the vehicle type as the taxi fee Cm from the boarding position to the current position, the initial ride fee is displayed in the display field 322 (FIG. 8B). Display). Further, since the difference between the fee Co and the fee Cm is sent from the server 2 as the taxi fee Ct from the current position to the destination, the difference fee is displayed in the display field 323 (see FIG. 8B). (Step S12).

  The control unit 101 receives the characteristics of the taximeter timing display unit sent from the server 2, and displays the received characteristics of the taximeter timing display unit in the display field 323 (see FIG. 8B). ) (Step S13).

  Next, the control unit 101 determines whether or not a predetermined time, for example, 20 seconds has elapsed (step S14). When determining that the predetermined time has elapsed, the control unit 101 uses the current position data measured by the GPS positioning unit 107 as the mobile phone terminal. 1 is sent to the server 2 in association with the identification information (step S15).

  Next, the control unit 101 determines whether or not taxi fare information has been received from the server 2 (step S16). If it is determined that taxi fare information has not been received from the server 2, the process proceeds to step S14. The process after step S14 is repeated.

  When it is determined in step S14 that the predetermined time has not elapsed, the control unit 101 monitors the operation input from the touch panel 114 and determines whether the taxi fare to the current position in the display field 322 has been corrected. It discriminate | determines (step S21 of FIG. 11). When it is determined in step S21 that the taxi fare Cm up to the current position in the display field 322 has not been corrected, the control unit 101 returns the process to step S14 and repeats the processes after step S14.

  When it is determined in step S21 that the taxi fare Cm up to the current position in the display column 322 has been corrected, the control unit 101 determines the taxi fare up to the current position displayed in the display column 322 according to the correction input. Change (step S22). And the control part 101 calculates | requires difference (DELTA) Cm of the charge Cm before the correction | amendment, and the charge Cma after the correction | amendment, The taxi charge Co from the boarding position currently displayed on the display column 321 to the destination using the difference (DELTA) Cm. Is corrected (step S23).

  Then, the control unit 101 sends the difference ΔCm obtained in step S23 to the server 2 (step S24). Then, the control part 101 returns a process to step S14, and repeats the process after this step S14.

  If it is determined in step S16 that the taxi fare information has been received from the server 2, the control unit 101 uses the received taxi fare from the boarding position to the destination in the display field 321 of the display screen 113D of the display 113. The fee is updated, and the fee in the display field 322 of the display screen 113D is updated with the taxi fee from the received boarding position to the current position (step S17).

  Next, the control unit 101 determines whether or not the “stop” icon 308 (see FIG. 8B) has been pressed (step S18), and determines that the “stop” icon 308 has not been pressed. Sometimes, the process returns to step S14, and the processes after step S14 are repeated. If it is determined that the “stop” icon 308 has been pressed, the control unit 101 notifies the server 2 of the stop (step S19), and then ends this processing routine.

  Next, the flow of processing in the server 2 will be described with reference to the flowcharts of FIGS. In the following description, each of the transmission / reception processing unit 203, route search unit 204, current position fee calculation unit 206, destination fee calculation unit 207, and notification timing determination unit 212 in the configuration of the server 2 shown in FIG. The function processing unit will be described as a case where the control unit 201 executes as a software processing function.

  When the control unit 201 of the server 2 receives an access from the mobile phone terminal 1 and receives a request for providing a taxi fare calculation service together with the identification information, the control unit 201 executes processing from the start of FIG.

  First, the control unit 201 of the server 2 determines whether or not a search request for a taxi company including the current location in the business area is received based on the pressing of the “ride at current location” icon 306 on the mobile phone terminal 1. (Step S31). When it is determined in this step S31 that a request for searching for a taxi company including the current location within the business area has been received, the control unit 201 sets the current position of the mobile phone terminal 1 sent from the mobile phone terminal 1 within the business area. The taxi company information to be searched is retrieved from the regional taxi company table stored in the regional taxi company database, and the obtained taxi company information is used as a list. (Step S32).

  After step S32, the control unit 201 determines whether or not a “charge calculation” request has been received (step S33). Even when it is determined in step S31 that a search request for a taxi company in the vicinity of the current location has not been received, the control unit 201 proceeds to step S33 and determines whether or not a “charge calculation” request has been received. .

  When it is determined in this step S33 that the “charge calculation” request has not been received, the control unit 201 determines whether or not a cancellation notification is received from the mobile phone terminal 1 (step S34), and the cancellation notification is issued. If it is determined that it has not been received, the process returns to step S31, and the processes after step S31 are repeated. If it is determined in step S34 that a cancellation notice has been received from the mobile phone terminal 1, the control unit 201 ends this processing routine.

  When it is determined in step S33 that the “charge calculation” request has been received, the control unit 201 refers to the route information from the designated boarding position to the destination, traffic information obtained through the Internet, accident information, and the like. The taxi fare when the taxi travels the route of the search result, the information necessary for calculating the taxi fare, such as the designated taxi company, vehicle type, and usage time zone, and the traffic information acquired via the Internet Is calculated based on the taxi fare system table in the taxi fare system table storage unit 210, and the calculation result is transmitted to the mobile phone terminal 1 (step S35).

  Next, the control unit 201 determines whether a search request for a taxi company including the current location in the business area has been received from the mobile phone terminal 1 (step S36). When it is determined in this step S36 that a search request for a taxi company including the current location within the business area has been received, the control unit 201 sets the current position of the mobile phone terminal 1 sent from the mobile phone terminal 1 within the business area. The taxi company information including the information is retrieved from the regional taxi company table stored in the regional taxi company database, and the obtained taxi company information is used as a list. (Step S37).

  Next to step S37, the control unit 201 determines whether or not a “boarding start” notification indicating an actual taxi ride has been received (step S38). Even when it is determined in step S36 that a search request for a taxi company in the vicinity of the current location has not been received, the control unit 201 proceeds to step S38 and determines whether or not a “boarding start” notification has been received. .

  When it is determined in this step S38 that the “boarding start” notification has not been received, the control unit 201 determines whether or not a cancellation notification has been received from the mobile phone terminal 1 (step S39). If it is determined that it has not been received, the process returns to step S36, and the processes after step S36 are repeated. If it is determined in step S39 that a cancellation notification has been received from the mobile phone terminal 1, the control unit 201 ends this processing routine.

  If it is determined in step S38 that the notification of “boarding start” has been received, the control unit 201 recognizes the current position of the mobile phone terminal 1 included in the notification as the actual taxi boarding position, and The route from the position to the designated destination is searched again in the same manner as in step S35. The use time zone at this time is specified from the boarding time. Then, the control unit 201 obtains the taxi fare when the taxi travels the route of the search result, information necessary for calculating the taxi fare such as the designated taxi company, vehicle type, use time zone, and the traffic acquired through the Internet. Considering the delay due to the information, the calculation is made based on the taxi fare system table in the taxi fare system table storage unit 210, and the calculation result is transmitted to the mobile phone terminal 1 (step S41 in FIG. 13). In step S31, the control unit 201 obtains an initial ride fee according to the designated taxi company, vehicle type, and usage time zone, and uses the obtained initial ride fee as a taxi fee at the current position. To send to.

  Next, the control unit 201 refers to the taximeter information storage unit 211 according to the taxi company information included in the notification received from the mobile phone terminal 1 in step S38, and determines the taxi mounted on the taxi that is on board. The determined characteristic of the taximeter timing display section is transmitted to the mobile phone terminal 1 (step S42).

  Next, the control unit 201 determines whether or not data on the current position has been received from the mobile phone terminal 1 (step S43). When it is determined in step S43 that the current position data has been received from the mobile phone terminal 1, the control unit 201 associates the received current position data with the identification information of the mobile phone terminal 1 and the reception time thereof. Then, it accumulates in the movement locus accumulating unit 205 (step S44).

  When it is determined in step S43 that the current position data has not been received from the mobile phone terminal 1, or after the processing of step S44 is completed, the control unit 201 has reached the time of notification of taxi fare. It is determined whether or not (step S45).

  When it is determined in this step S45 that the notification timing has come, the control unit 201 executes the processing of the current position fee calculation unit 206 described above, and uses the stored data of the mobile track terminal 1 of the movement locus storage unit 205. Based on the actual travel route and travel time of the taxi, a taxi fare Cm from the boarding position to the current position at the notification timing is calculated (step S46).

  Next, the control unit 201 executes the above-described processing of the destination fee calculation unit 207, re-searches and specifies the route from the current position to the destination, and collects traffic information (such as traffic jam information) via the Internet. Is used to calculate the taxi fare for the route, and the calculated taxi fare is added to the taxi fare Cm from the boarding position to the current position calculated in step S46 to get from the boarding position to the destination. The taxi fare Co is obtained (step S47).

  Next, the control unit 201 determines the taxi fare Cm from the boarding position to the current position obtained in step S46, the taxi fare Ct from the current position to the destination obtained in step S47, and the taxi fare from the boarding position to the destination. Co is transmitted to the mobile phone terminal 1 (step S48).

  Next, the control unit 201 determines whether or not a stop notification is received from the mobile phone terminal 1 (step S49). If it is determined that a stop notification is not received, the control unit 201 returns the process to step S43. The processes after S43 are repeated. If it is determined in step S43 that a stop notification has been received from the mobile phone terminal 1, the control unit 201 ends this processing routine.

  If it is determined in step S45 that the taxi fare notification timing has not arrived, has the control unit 201 received the difference ΔCm based on the correction of the taxi fare Cm from the mobile phone terminal 1 to the current position? It is determined whether or not (step S51 in FIG. 14). When it is determined in step S51 that the difference ΔCm has not been received from the mobile phone terminal 1, the control unit 201 returns the process to step S43 and repeats the processes after step S43.

  If it is determined in step S51 that the difference ΔCm is received from the mobile phone terminal 1, the control unit 201 holds the difference ΔCm (step S52). After step S52, the control unit 201 returns the process to step S43, and repeats the processes after step S43.

  After that, when calculating the taxi fare from the boarding position to the current position at the notification timing, the control unit 201 calculates the taxi fare based on the taxi travel route and travel time accumulated in the movement locus accumulating unit 205. After calculating Cm, the charge Cm of the calculation result is corrected by the difference ΔCm. Then, the server 2 sends the corrected taxi fee Cm ′ to the mobile phone terminal 1 instead of the taxi fee Cm.

[Effect of the embodiment]
As described above, according to the above-described embodiment, the fare to the current position at the notification timing after the taxi ride is always according to the actual travel route and travel time of the taxi, The taxi fare to the ground includes the fare up to the current position, and thus reflects the fare that changes in real time according to the actual taxi driving state.

  And on the display screen of the mobile terminal, in addition to the taxi fare from the boarding position to the destination, the fare from the boarding position to the current position at the notification timing is also displayed, so the distance from the boarding position to the current position is displayed. Considering the error between the fare and the taxi meter display fee, the taxi fare from the boarding position to the destination can be grasped more accurately.

  Moreover, in the above-described embodiment, the taxi fare from the boarding position calculated by the server to the current position is corrected so that the user matches the taxi fare of the taxi currently on board, so that The taxi fare to the destination can also be corrected to match the correction. Therefore, the taxi fare from the boarding position to the destination displayed on the display screen of the mobile phone terminal can include the difference from the taxi meter, and the fare information more reliable for the user. It becomes.

  In this embodiment, since the difference between before and after the taxi fare correction from the boarding position to the current position or the taxi fare from the corrected boarding position to the current position is sent to the server from the mobile phone terminal, the server The difference between the display value of the taximeter and the calculated value can be grasped. Then, the server reflects the difference in the taxi fare from the boarding position to the destination, thereby making the taxi fare from the boarding position to the destination more approximate to the taxi fare displayed on the taxi meter. Is possible. Therefore, it is possible to provide a highly reliable fee closer to the actual fee as a taxi fee from the boarding position to the destination for the user of the mobile phone terminal.

  And in the above-mentioned embodiment, since the characteristic of the timing display part of a taxi meter is displayed on the display screen of a portable terminal, it is possible to monitor the timing when the display fee of the taxi meter of the taxi on board increases. it can.
