Therefore, the current position of the latest waiting person is always registered in the waiting database 233.

FIG. 10 is a diagram showing a flow of processing in the carpool support system of the present embodiment.
First, the position information acquisition unit 111 of the user terminal 10 calculates the current position from the radio wave received by the GPS radio wave reception unit 105 in accordance with the operation of the applicant (S31). For example, a screen 50 as shown in FIG. 11 is displayed on the user terminal 10. When the button 501 provided on the screen 50 is pressed, the waiting information acquisition unit 112 transmits a waiting information acquisition request including the current position to the server 20 (S32).

In response to the reception of the waiting information acquisition request, the server 20 performs a waiting information search process related to the waiting person in the vicinity of the applicant (S33). The flow of the waiting information search process is shown in FIG.
The waiting information providing unit 211, for each waiting information stored in the waiting database 233, from the current position of the applicant included in the waiting information acquisition request to the current position of the waiting person included in the waiting information. The distance is calculated, and waiting information whose calculated distance is within a predetermined threshold is read from the waiting database 233 (S401). The waiting information providing unit 211 searches the platform database 232 for platform information at a reference position that is closest within a predetermined distance from the current location of the applicant (S402). For example, the waiting information providing unit 211 calculates the distance from the reference position of the landing information to the current position of the waiting person included in the waiting information acquisition request for each piece of landing information registered in the landing database 232. The shortest of the calculated distances is selected, and it is determined whether or not the selected distance is shorter than a predetermined distance. The predetermined threshold value in step S401 and the predetermined distance in step S402 may be the same value or different values.

  When there is the platform information searched as described above (S403: YES), the waiting information providing unit 211 sets the distance from the reference position of the platform to the current position of the waiting person for each read waiting information at a predetermined interval. (For example, it is a predetermined value such as 50 centimeters or 1 meter. For example, an interval between passengers in the case of forming a matrix can be investigated and statistically processed.) The rank is attached to each waiting information (S404). The result obtained by rounding the quotient to an integer by rounding off or rounding down is the ranking. In addition, the waiting information providing unit 211 sets the boarding name of the waiting information as the boarding name (S405).

  On the other hand, when there is no platform information searched as described above (S403: NO), the waiting information providing unit 211 has a value indicating that the rank of each waiting information read is unknown ("0" in this embodiment). Is attached (S406). In addition, the waiting information providing unit 211 sets the current position in the platform name (S407). For example, the waiting information providing unit 211 may access a map database that provides map information, obtain a place name on the map corresponding to the current position, and use it as a platform name.

  As described above, when the waiting information is searched, the waiting information providing unit 211 transmits the read waiting information and the platform name to the user terminal 10 (S34).

  When the waiting information acquisition unit 112 of the user terminal 10 receives the waiting information and the landing name from the server 20, the waiting information output unit 113 outputs the received waiting information and the landing name to the output device 107 (S35). FIG. 13 is a diagram illustrating an example of a screen 51 on which waiting information is output. As shown in the figure, on the screen 51, a platform name 511 is displayed, and a list 512 of searched waiting information is displayed. On the screen 51, the waiting information 513 is selected according to the operation of the input device 106 such as a push button, a mouse, or a touch panel. When the negotiation partner designation unit 114 receives the selected waiting information 513, the contact acquisition unit 115 transmits a contact acquisition request in which the user ID included in the received waiting information 513 is set to the server 20 (S36). .

  When receiving the contact acquisition request from the user terminal 10, the contact providing unit 212 of the server 20 reads out user information corresponding to the user ID included in the received contact acquisition request from the user database 231 (S37). The contact providing unit 212 transmits the contact information in which the user ID, the mobile phone number, the mail address, and the messenger ID included in the read user information are set to the user terminal 10 (S38).

  When the contact acquisition unit 115 of the user terminal 10 receives the contact information from the server 20, the communication start unit 116 establishes a communication with the negotiation partner by starting a program for making a call, an e-mail program, a messenger program, or the like. Communication for performing communication in is established (S39). The communication start part 116 can display the screen 52 as shown in FIG. 14, for example, and can select a communication means with a negotiation partner. 14 includes a button 521 for selecting a call, a button 522 for selecting an e-mail, and a button 523 for selecting a messenger. If any one of the mobile phone number, mail address, and messenger ID is not set in the contact information, the communication start unit 116 prevents the corresponding buttons 521 to 523 from being selected. In the example of FIG. 14, the mobile phone number is not included in the contact information, and the button 521 cannot be selected on the screen 52. By pressing the button 522 or the button 523, the user can select to communicate with the negotiating partner by e-mail or messenger. For example, when the button 523 is pressed, the communication start unit 116 activates the messenger program by designating a parameter with the messenger ID included in the contact information as a communication partner, for example. FIG. 15 is a diagram illustrating an example of the messenger screen 53. In the example of FIG. 15, the applicant H exchanges messages with the queuing party B and applies for sharing with B. In this way, carpooling negotiations are conducted between the applicant and the waiting party.

  On the other hand, if there is no waiting person at the destination in the same direction, the destination of the applicant is entered in the input field 514 on the screen 51 of FIG. 13 displayed in step S35, and the registration button 515 is pressed. The When the destination input unit 117 receives the destination input in the input field 514, the waiting information transmission unit 118 receives waiting information specifying the received destination and the user ID operating the user terminal 10. It transmits to the server 20 (S42). Note that the user ID may also be input on the screen 51.

  The waiting information registration unit 213 of the server 20 registers the waiting information received from the user terminal 10 in the waiting database 233 (S41). In this way, the applicant is newly registered as a waiting person together with the destination (that is, the applicant (the “second passenger” of the present invention) is the waiting person (the “first passenger” of the present invention)). That is).

  As described above, according to the carpooling support system of the present embodiment, a list of waiters and their destinations can be presented to the applicant. Therefore, the applicant can easily grasp what destination is the waiting party.

  In addition, according to the carpooling support system of the present embodiment, the applicant selects one queuing person with reference to the queuing party's destination, and makes a call using a mobile phone, transmission / reception of an e-mail, message in a messenger service. It is possible to negotiate carpooling with the selected queuing person by exchanging them. Therefore, it is possible to smoothly negotiate carpooling and meet the needs among carpoolers.

  In the carpooling support system according to the present embodiment, the current position of the waiting person is periodically transmitted to the server 20 and the waiting database 233 of the server 20 is updated. Therefore, even in a situation where the current position of the waiter changes every moment as in a taxi stand, the waiting information is searched based on the latest current position of the waiter. Therefore, it is possible to search for a waiting person that is surely present in the vicinity of the applicant. In addition, the latest rank can be provided for the waiter.

  In addition, according to the carpooling support system of the present embodiment, since the rank of the waiter indicating how far the waiter is lined up is attached to the wait information, the applicant refers to the rank, You can negotiate carpooling with the waiters in front of you. Therefore, the applicant can get on a taxi quickly. In addition, since the waiter is more likely to apply for carpooling from the applicant earlier as they line up in front, the possibility of receiving application from the carpooling partner before actually getting in the taxi is increased. be able to.

  In the carpooling support system of this embodiment, all the waiting information of the waiting person in the vicinity of the applicant is transmitted to the applicant, but the destination is set in the waiting information acquisition request, and the waiting information acquisition request is set. Only waiting information that matches the set destination may be transmitted to the user terminal 10.

  Further, only the waiting information of the waiting person whose destination is in the same direction may be provided. A software configuration example of the server 20 in this case is shown in FIG. The server 20 further includes a destination database 234. As shown in FIG. 17, the destination database 234 stores the position of the destination on the map for each destination. Note that the destination database 234 may manage general map information, or the destination database 234 is not provided, and the location of the destination is obtained by accessing the map server providing the map information. You may make it do. Further, when providing only the waiting information of the waiting person whose destination is the same direction, the waiting information acquisition unit 112 of the user terminal 10 accepts the input of the applicant's destination, and the waiting information acquisition request includes The destination of the applicant is set together with the current location. The waiting information providing unit 211 of the server 20 receives only the waiting information in which the direction from the landing position to the applicant's destination position is close to the direction from the landing position to the waiting person's destination position. To provide.

  FIG. 18 is a diagram showing a flow of a waiting information search process in the case where only the waiting information of the waiting person having the same destination is provided. The process shown in FIG. 18 is the same as the process of FIG. 12 described above until step S407.

  The waiting information providing unit 211 reads the position corresponding to the destination included in the waiting information acquisition request from the destination database 234 and sets the longitude and latitude to (Lo1, La1) (S408). The waiting information providing unit 211 sets the position (longitude, latitude) of the platform as (Lo0, La0), and sets the first vector (x1, y1) from the platform to the destination of the applicant as (Lo1-Lo0, La1- (La0) is calculated (S409). The waiting information providing unit 211 performs the following processing for each of the waiting information acquired up to step S407.

  The waiting information providing unit 211 reads the position of the destination included in the waiting information from the destination database 234, and sets the longitude and latitude to (Lo2, La2) (S410). The waiting information providing unit 211 calculates the second vector (x2, y2) from the landing to the destination of the waiting person using (Lo2-Lo0, La2-La0) (S411). The waiting information providing unit 211 calculates the angle θ of the first and second vectors by an arc cosine with respect to x1 × y1 + x2 × y2, that is, θ = acos (x1 × y1 + x2 × y2) (S412).

  If the angle θ is smaller than the predetermined threshold (S413: YES), the waiting information providing unit 211 determines to transmit the waiting information (S414), and if the angle θ is equal to or larger than the predetermined threshold (S413: NO). ), It is determined that the waiting information is not transmitted (S415).

  The waiting information providing unit 211 transmits only the waiting information determined to be transmitted to the user terminal 10. In this way, it is possible to extract only the waiting information of the waiting person whose destination is in the same direction as the applicant. Note that the waiting information providing unit 211 does not determine whether or not to transmit the waiting information in steps S413 to S415, but determines the priority of the waiting information so as to increase as the angle θ decreases. You may make it attach a priority to information.

  In addition, the waiting information providing unit 211 calculates the azimuth from the landing position to the destination position, for example, 16 azimuths (north, north to northeast, northeast ... north to northwest), and Only waiting information in which the heading toward the destination and the heading toward the destination of the waiting person from the landing are the same may be transmitted to the user terminal 10.

  In addition, the waiting information providing unit 211 may present only waiting persons who have the same route from the landing to the destination. For example, the waiting information providing unit 211 acquires a destination position included in the waiting information acquisition request and a destination position included in the waiting information, and is a general method used in a car navigation system. To calculate the first route from the location of the landing to the location of the applicant's destination and the second route from the location of the landing to the destination of the waiter, and the overlap of the first and second routes Calculate the distance that overlaps the route with the longer distance for the route with the shorter distance than the predetermined threshold, that is, the ratio of the overlapping distance to the total distance of the route with the shorter distance. However, it can be determined whether or not it is larger than a predetermined threshold, and only the waiting information determined that the degree of overlap is large can be transmitted to the user terminal 10. Alternatively, the overlapping ratio may be attached to the waiting information and transmitted to the user terminal 10 of the applicant. The overlapping distance may be added to the waiting information and transmitted to the user terminal 10 of the applicant. The overlapping ratio and the overlapping distance may be transmitted to the user terminal 10 of the waiting person.

  In the present embodiment, the user terminal 10 is assumed to be a portable computer such as a mobile phone or a PDA. However, the present invention is not limited to this. For example, the user terminal 10 is not possible such as a personal computer or a workstation installed at a taxi stand. It may be a portable computer.

  In the present embodiment, the vehicle is a taxi. However, the vehicle is not limited to a taxi, and may be any vehicle that can carry a passenger to a destination according to the passenger's request. That is, for example, a bicycle or a motorcycle may be used.

  In addition, the current position is set in the waiting information acquisition request, but information for identifying the taxi stand (hereinafter referred to as “stop ID”) is set and corresponds to the landing ID included in the waiting information acquisition request. The reference position to be searched may be searched from the landing database 232, and the waiting information including the current position within a predetermined distance from the reference position may be searched from the waiting database 233. For example, a platform ID is posted for each taxi platform that provides a service by the carpool support system, and an applicant or waiting person inputs the posted platform ID to the user terminal 10 or sets the platform ID. A platform ID providing device provided to the user terminal 10 by wireless communication, infrared communication, or the like can be installed for each platform. Thereby, even an applicant who uses the user terminal 10 having no GPS function can participate in the service by the carpool support system of the present embodiment.

  In this embodiment, the waiting information for the waiting person within a predetermined distance from the applicant's current position included in the waiting information acquisition request is searched. However, the present invention is not limited to this. A nearby platform may be searched from the platform database 232, and waiting information including the current position of the waiting party within a predetermined distance from the reference position of the platform may be searched from the waiting database 233. In this case, in the process of FIG. 12, step S401 is omitted, and if there is the nearest platform information within a predetermined distance from the applicant's current position (S403: YES), a waiting information providing unit is provided before step S404. 211, for each piece of waiting information stored in the waiting database 233, calculates the distance from the reference position of the landing to the current position of the waiting information, and sends the waiting information whose calculated distance is equal to or less than a predetermined threshold from the waiting database 233. Read it out. In addition, when there is no landing information within a predetermined distance from the current position of the applicant (S403: NO), the waiting information providing unit 211 determines each waiting information stored in the waiting database 233 before step S406. The distance from the applicant's current position included in the waiting information acquisition request to the current position of the waiting information is calculated, and waiting information whose calculated distance is equal to or less than a predetermined threshold is read from the waiting database 233. . In the present embodiment, contact information is provided only for the partner selected by the applicant as a negotiation partner. For example, the waiting information providing unit 211 provides the user ID included in the waiting information together with the waiting information. Corresponding user information may be attached to the waiting information and transmitted to the user terminal 10. In this case, the user terminal 10 can start communication at the same time as the negotiation partner is selected.

  In this embodiment, contact information is provided unconditionally in response to a request from the applicant. However, confirmation may be made to the waiter. In this case, the applicant inputs gender, age, etc., and the server 20 notifies the waiting person of the applicant's gender, age, etc. by e-mail, messaging service, voice call, etc. Acceptance information indicating whether or not the queuing party will receive a negotiation for carpooling from the applicant is received from the user terminal 10 of the queuing person by e-mail, message, telephone DTMF sound recognition, etc., and the queuing party is negotiated The contact information can be transmitted to the user terminal 10 of the applicant only when the acceptance information indicating is received. Thereby, since the waiting person can grasp | ascertain the outline of what kind of person the applicant is, it becomes possible to perform easily, for example, avoiding a carpool with the opposite sex.

  In addition, before the server 20 transmits the contact information to the user terminal 10 of the applicant so as to manage the registration status of the personal information indicating whether or not the personal information is registered for each user, The registration status of the applicant along with the user ID and telephone number of the applicant may be transmitted to the user terminal 10 of the waiter related to the waiting information. Thereby, since the waiting person can determine whether to trust the applicant according to the anonymity of the applicant, for example, when the user ID not registering personal information is not trusted, It is possible to refuse contact from the user ID (e-mail, message, incoming phone call).

  In this embodiment, the rank is calculated according to the distance from the reference position of the landing. However, the waiter may input the rank and register it in the server 20. In this case, the destination input unit 117 of the user terminal 10 can receive the rank of the waiter along with the destination, and can set the destination and rank in the wait information.

  If there is no landing information within a predetermined distance from the current position of the applicant, the rank is unknown in step S406 in FIGS. 12 and 18, but the rank is calculated only from the current position included in the waiting information. You may make it do. In this case, for example, the rank can be determined so that the rank of the waiting person far from the applicant becomes higher. Further, among the waiting information read out in step S406, the information including the current position farthest from the current position included in the waiting information acquisition request is set as the reference waiting information, and the rank of the reference waiting information is set to “1”. The order of other waiting information may be calculated by dividing the distance from the current position included in the waiting information to the current position included in the reference waiting information by the predetermined interval described above. Determining the rank in this way can be applied, for example, when the landing information is omitted.

  In addition, the update time of the waiting information is attached to the waiting information, and the updating time is updated to the latest time every time the current position is updated, and the waiting information registered before a predetermined time is periodically updated. It may be deleted.

  In this embodiment, the information on the waiter is provided to the applicant, but the information on the applicant may be provided to the waiter. In this case, the user terminal 10 receives an input of the user ID and the destination from the applicant, and information (hereinafter referred to as “application information”) including the received user ID, the current position, and the destination is sent to the server 20. The server 20 identifies the landing at the reference position closest to the current position included in the application information and within the predetermined distance, and searches the waiting database 233 for waiting information within the predetermined distance from the reference position of the identified landing. Then, the contact information corresponding to the user ID included in the searched waiting information is read from the contact database 232, and the e-mail or messenger ID, telephone number, etc. included in the read contact is used as the destination. The user ID, destination, contact information, etc. of the applicant may be sent by text message, voice message, etc. There. Thereby, it becomes possible to negotiate with the applicant from the waiting person. Further, the server 20 transmits waiting information to the user terminal 10 of the applicant, and transmits the user ID, destination, contact information, etc. of the applicant to the user terminal 10 of the waiting person. Good. Thereby, since it is possible to negotiate the carpooling from both the applicant and the waiter, it is possible to quickly find the caring partner.

  Although the present embodiment has been described above, the above embodiment is intended to facilitate understanding of the present invention and is not intended to limit the present invention. The present invention can be changed and improved without departing from the gist thereof, and the present invention includes equivalents thereof.
