  Hereinafter, a bus-mounted terminal device according to an embodiment of the present invention will be described with reference to the drawings. In this embodiment, the wireless inter-terminal network with a relay function is an ad hoc network. An ad hoc network is a network composed of terminals that can be connected wirelessly, and is a network having a relay function in the form of multi-hop communication that connects many terminals to each other.

  FIG. 1 shows a bus-mounted terminal device according to the first embodiment of the present invention, FIG. 2 shows a bus-stopped terminal device installed at a bus stop, and FIG. 3 shows a bus-mounted terminal device and a bus-stopped terminal. FIG. 4 shows a bus route provided with the bus operation support system. FIG.

  First, referring to FIG. 4, the buses 100 and 102 travel along the bus routes 104 and 106, respectively. A bus stop 108 is installed on the bus lines 104 and 106 at an appropriate interval. Bus lines 104 and 106 can be changed, and a transfer bus stop 110 is installed at the transfer place.

  In FIG. 4, when the bus 100 is the own bus, the bus route 104 is the own bus route, the bus route 106 is the transfer bus route, and the bus 102 is another bus of the transfer bus route.

  FIG. 4 shows a part of the bus route, and the bus routes 100 and 102 may further have other transfer bus stops and may be in contact with other transfer bus routes.

  Next, referring to FIG. 3, the bus operation support system 1 includes a bus-mounted terminal device 3 and a bus stop terminal device 5. A similar bus-equipped terminal device 3 is mounted on each bus, and a similar bus stop terminal device 5 is installed at each bus stop. The bus-equipped terminal device 3 and the bus stop terminal device 5 have a wireless communication function and form an ad hoc network 7.

  An ad hoc network is a network composed of terminal devices equipped with a relay function. Each terminal device has a data transmission / reception function and a function of relaying data for communication between other terminal devices, whereby a relatively small network is easily formed by the terminal device. In the present embodiment, such an ad hoc network is applied to communication between a bus and a bus stop terminal device, so that a small bus operation support system is easily formed on the bus route.

  In FIG. 3, the left bus terminal device 3 is mounted on the bus 100 on the bus route 104, and the lower bus terminal device 3 is mounted on the bus 102 on the bus route 106. Then, these two bus-equipped terminal devices 3 communicate using the relay function of the bus stop terminal device 5 installed at the transfer bus stop 110 and the two bus stops 108.

  The ad hoc network 7 may be formed by more bus-equipped terminal devices 3 and bus stop terminal devices 5. In addition, the configuration of the ad hoc network 7 changes according to the travel of the bus.

  Next, referring to FIG. 2, the bus stop terminal device 5 includes an ad hoc transmission / reception unit 40 having a communication function with the ad hoc network 7, an output unit 42 such as a display, and a control unit 44 that controls these units.

  The control unit 44 includes an arrival time acquisition unit 46 and an arrival time presentation unit 48. The arrival time acquisition unit 46 controls the ad hoc transmission / reception unit 40 to communicate with the bus-mounted terminal device 3 on the bus traveling on the bus route on which the bus stop terminal device 5 is installed via the ad hoc network 7. And the arrival time acquisition part 46 requests | requires transmission of the information of the arrival time to the own bus stop to the bus-mounted terminal device 3, and acquires the information of the arrival time received from the bus-mounted terminal device 3. The arrival time presentation unit 48 controls the output unit 42 to present arrival time information to the passengers at the bus stop.

  The bus stop terminal device 5 is a computer device having a communication function in terms of hardware, and includes a communication device that realizes a transmission / reception function in addition to a computer configuration such as a memory, a CPU, an input / output interface, and an external storage device. The same applies to the bus-equipped terminal device 3. Furthermore, the bus-mounted terminal device 3 includes a current position detection function used in the vehicle navigation device, a map database, and the like, and a computer is configured to control them.

  Referring to FIG. 1, the bus-equipped terminal device 3 includes an ad hoc transmission / reception unit 10, a current position detection unit 12, a local bus route data storage unit 14, an input unit 16, an output unit 18, and a control unit 20 that controls them.

  The ad hoc transmission / reception unit 10 provides a wireless transmission / reception function via the ad hoc network 7.

  The current position detector 12 has a GPS function and detects the current position of the own bus. The current position detection unit 12 may include a position detection function based on autonomous navigation that uses detection signals from the vehicle speed sensor and the direction sensor in addition to the GPS function.

  The own bus route data storage unit 14 stores own bus route data for obtaining the arrival time from the current position to each bus stop on the own bus route. The own bus route data is also used to calculate the arrival time at the transfer bus stop.

  FIG. 5 shows an example of information of the own bus route data in the form of a map. The own bus route data includes route shape data, position data of each bus stop, and required time data for each section when traveling along the route. By using such data, it is possible to calculate the time required to reach each bus stop by applying the required time calculation technique in the vehicle navigation device. Note that the own bus route data is not limited to the above form, and may be a table of required time from each position on the route to all bus stops on the route.

  Returning to FIG. 1, the input unit 16 is a button, a switch, a microphone, or the like, and is operated by a driver. The output unit 18 is a display, a speaker, and a printer. A display and a speaker are provided in the driver seat and the passenger seat. The driver's seat display and speaker output instructions to the driver. The passenger seat display and speakers output guidance to passengers. Furthermore, the printer is used for issuing a transfer ticket to be described later.

  Moreover, the control part 20 has the arrival time calculation part 22, the arrival time transfer part 24, and the transfer assistance part 30 like illustration. The arrival time calculation unit 22 refers to the own bus route data stored in the own bus route data storage unit 14 based on the current position detected by the current position detection unit 12, and calculates the arrival time to each bus stop ahead. As described above, the arrival time calculation unit 22 calculates the arrival time with the bus stop as the destination by applying the data processing of the navigation device.

  The arrival time may be calculated based on the traffic jam information, thereby improving the accuracy of the arrival time. The traffic jam information may be incorporated in the own bus route data in advance. In this case, the traffic jam information preferably represents a change in traffic jam according to the day of the week and the time zone. The own bus route data of FIG. 5 may have the section required time for each day of the week and time zone reflecting the traffic congestion regarding the section required time of each section. The arrival time calculation unit 22 calculates the arrival time using the required time corresponding to the current time.

  The traffic jam information may be acquired from outside by communication. The traffic jam information may be VICS information. Further, the traffic jam information may be obtained from a bus-mounted terminal device of another bus on the same bus route. In this case, a plurality of bus-equipped terminal devices on the bus route exchange traffic information via the ad hoc network 7. The traffic jam information may be the difference between the actual required time of each section and the reference required time. The traffic jam information may be the actual time required for each section. The arrival time calculation unit 22 calculates the arrival time based on the traffic jam information thus obtained.

  The arrival time transfer unit 24 transmits and receives the arrival time at the transfer bus stop to / from bus-equipped terminal devices on other buses on the transfer bus route through communication via the ad hoc network 7.

  The arrival time transfer unit 24 includes an arrival time acquisition unit 26 and an arrival time providing unit 28. The arrival time acquisition unit 26 sends an arrival time request to another bus-equipped terminal device, and acquires information on the arrival times of other buses that have returned. The arrival time providing unit 28 receives the arrival time request from another bus-equipped terminal device having the same configuration, and the arrival time of the own bus calculated by the arrival time calculation unit 22 in response to the arrival time request. Information is sent to the requester.

  FIG. 6 shows an example of exchange of arrival times. The two bus-equipped terminal devices 3A and 3B have the same configuration. Here, the bus-mounted terminal device 3A acquires arrival time information from the bus-mounted terminal 3B. In FIG. 6, only arrival time calculation units 22A and 22B, arrival time transfer units 24A and 24B, arrival time acquisition units 26A and 26B, and arrival time providing units 28A and 28B included in the bus-equipped terminal devices 3A and 3B are shown. Is omitted.

  The arrival time acquisition unit 26A of the bus-equipped terminal device 3A identifies the next transfer bus stop from the current position and the own bus route data. Then, the arrival time acquisition unit 26A sends an arrival time request including identification information of the own bus route and information indicating the next transfer bus stop to the ad hoc network 7 in a broadcast format. This arrival time request is received by the bus-equipped terminal device 3B.

  The arrival time providing unit 28B of the bus-mounted terminal device 3B analyzes the arrival time request. The arrival time providing unit 28B determines whether or not the transfer bus stop indicated in the arrival time request is on the own bus route based on the own bus route data. When the transfer bus stop of the arrival time request is on the own bus route, the arrival time providing unit 28B determines that the own bus has not yet passed the transfer bus stop based on the current position and the own bus route data. Then, the arrival time providing unit 28B transmits the arrival time to the target transfer bus stop calculated by the arrival time calculating unit 22B together with the identification information of the own bus to the bus-equipped terminal device 3A. This information is acquired by the arrival time acquisition unit 26A of the bus-mounted terminal device 3A.

  In the above process, the arrival time acquisition unit 28 may acquire arrival time information from a plurality of bus-equipped terminal devices on the transfer bus route. Therefore, the arrival time acquisition unit 28 selects information on the earliest arrival time after the own bus and holds the information on the selected arrival time for subsequent processing.

  On an actual bus route, the bus travels in both directions. Therefore, it is preferable to perform the same processing for each traveling direction. For example, the arrival time acquisition unit 26 transmits an arrival time request with information indicating one direction of a transfer bus route, and then transmits an arrival time direction with information indicating another direction. When the arrival time information of the buses in both directions is returned in response to this request, the information is acquired. Thereafter, the same processing may be performed for the bus in each direction. However, in the following description, only the transfer to a one-way bus will be described for the sake of brevity.

  In addition, the function of the arrival time exchanging unit 24 is not limited to the above. If the arrival time can be exchanged with the bus-equipped terminal device on the transfer bus route, another processing may be performed.

  Returning to FIG. 1, in the control unit 20, the transfer support unit 30 determines the arrival time calculated by the arrival time calculation unit 22 and the arrival time of other buses acquired by the arrival time transfer unit 24 as described below. Based on the above, a transfer support process for supporting transfer at the transfer bus stop is performed.

  FIG. 7 shows a configuration example of the transfer support unit 30. The transfer support unit 30 includes a transfer ticket generation information storage unit 32, an arrival time difference calculation unit 34, and a transfer ticket output processing unit 36. In this configuration example, the transfer support unit 30 outputs a transfer ticket with a time limit with an appropriate transfer time limit, as will be described below. Here, the transfer ticket is used to provide a service for reducing the boarding fee of the bus to which the transfer is made. By using a transfer ticket, for example, the bus fee after transfer becomes 0, and for example, the initial fare becomes 0. Making the valid period of a transfer ticket unlimited or valid throughout the day leads to excessive service. In the present embodiment, the transfer time limit can be appropriately set in consideration of the cooperation between the buses before and after the transfer as described below.

  In FIG. 7, the transfer ticket generation information storage unit 32 stores information for generating a transfer ticket with a time limit with a transfer time limit. The arrival time difference calculation unit 34 calculates the arrival time difference between the own bus to the transfer bus stop and other buses on the transfer bus route. And the transfer ticket output process part 36 outputs the transfer ticket with a time limit which set the transfer time limit of the length according to the calculated arrival time difference with reference to the information of the transfer ticket production | generation information storage part 32. FIG. The transfer limit time is set longer than the arrival time difference by an appropriate length.

  Of the above configuration, the transfer ticket generation information storage unit 32 stores information on the contents of the transfer ticket in the present embodiment. This information is, for example, text, images, or both, and includes the title “Transit ticket with time limit” and a description of how to use it. In the transfer ticket information, the transfer bus stop and time limit fields are blank. The transfer ticket output processing unit 36 inserts the name of the next transfer bus stop into the transfer bus stop column of the transfer ticket information, inserts the transfer limit time into the time limit column, and thereby outputs the information of the transfer ticket to be output. Generate. The transfer ticket output processing unit 36 sends information on the transfer ticket to the printer which is the output unit 18 and causes the transfer ticket to be printed.

  In this embodiment, the transfer ticket is printed on a sheet such as paper. That is, the transfer ticket is a printed matter. However, the transfer ticket is not limited to the above within the scope of the present invention. The transfer may take the form of magnetic or electronic information. For example, a prepaid card or an IC card (contact type or non-contact type) is used. In this case, information on the time limit and the bus stop is written as information on the transfer ticket on the magnetic prepaid card or the IC card. The bus stop information may be a bus stop name or a bus stop number as long as the bus stop can be identified. In the next bus, a card reader is provided, and information on transfer tickets is read from a prepaid card or an IC card, and the contents are automatically determined. Based on the determination result, a process related to the charge, for example, a process not adding the initial boarding charge is performed. In such a configuration, the transfer ticket output processing unit 36 is provided with a magnetic output unit or an electronic information output unit so that information can be written to the card.

  Referring to FIG. 8, the transfer ticket output processing unit 36 adds the margin time TA to the arrival time difference TD calculated by the arrival time difference calculation unit 34. The total time TD + TA is set as the transfer limit time.

  FIG. 9 shows the operation of the control unit 20 of the bus-equipped terminal device 3 described above. In FIG. 9, the control unit 20 determines whether or not the vehicle has passed a bus stop just before the transfer bus stop based on the current position and the own bus route data (S10). When passing the bus stop just before, the arrival arrival calculation unit 22 calculates the arrival time to the transfer bus stop based on the current position and the own bus route data (S12). In addition, the arrival time acquisition unit 26 of the arrival time transfer unit 24 acquires the arrival time at the transfer bus stop from the bus-equipped terminal device on the other bus on the transfer bus route through communication via the ad hoc network 7 (S14). ).

  Next, the arrival time difference calculation unit 34 calculates the arrival time difference between the own bus to the transfer bus stop and other buses on the transfer bus route (S16). Here, the arrival time of the own bus is subtracted from the arrival time of other buses. Then, the transfer ticket output processing unit 36 refers to the information in the transfer ticket generation information storage unit 32, and outputs a transfer ticket with a time limit in which a transfer time limit of a length corresponding to the calculated arrival time difference is set (S18). ). Transfer tickets with a plurality of time limits are output for a plurality of passengers.

  The bus-mounted terminal device 3 according to the first embodiment of the present invention has been described above. According to the present embodiment, the bus-equipped terminal device 3 forms the ad hoc network 7 together with the terminal device along the bus route, thereby forming a small-scale system. The bus-equipped terminal device 3 is configured to use the ad hoc network 7 to send and receive the arrival time to the transfer bus stop with the other bus terminal devices, and to reach other buses on the own bus and the transfer bus route. Information processing that supports transfer using time. In this way, cooperation between buses of different bus routes can be favorably supported with a small-scale system.

  In addition, the bus-equipped terminal 3 according to the present embodiment outputs a transfer ticket with a time limit in which a transfer time limit of a length corresponding to the arrival time difference between the own bus to the transfer bus stop and other buses on the transfer bus route is set. Thus, it is possible to output a transfer ticket with a time limit with a transfer time limit of an appropriate length according to the arrival time difference, and support passenger transfer.

  According to the present embodiment, even in an area where a “transfer ticket” service is currently provided, the convenience of the service is improved by providing a transfer ticket in which an appropriate time limit is set in consideration of inter-bus cooperation. be able to. In addition, it is possible to provide a transit ticket even in an area where a “transfer ticket” service could not be provided. For example, since it is not easy to set an appropriate time limit so far, providing an all-day valid ticket as described above leads to excessive service, so in the area where the transfer ticket could not be provided, the system of the present embodiment Transfer tickets can be provided depending on application. Thus, according to the present embodiment, the application area of the transfer ticket can be expanded, thereby contributing to the convenience of bus transportation.

  Moreover, when the first embodiment is viewed as the bus operation support system 1, the bus operation support system 1 includes a bus stop terminal device 5 installed at a bus stop of a plurality of bus routes including a transfer bus stop, A bus-mounted terminal device 3 that is mounted on a route bus that travels on a bus route and forms an ad hoc network 7 together with the bus stop terminal device 5, and the buses of the plurality of bus routes are communicated via the ad hoc network 7. Means for acquiring information on arrival time at the transfer bus stop and means for performing information processing for supporting transfer between a plurality of bus routes based on the acquired information on arrival time. And by such bus operation support system 1, it is possible to favorably support cooperation between buses of different bus routes with an ad hoc type small-scale system.

  Thus, when the present invention is viewed as the bus operation support system 1, as a modification of the above-described embodiment within the scope of the present invention, for example, the function of the bus-equipped terminal device 3 is partially the bus stop terminal device 5. May be provided. For example, the bus stop terminal device 5 at the transfer bus stop inquires the terminal devices on the buses of a plurality of bus routes passing through the bus stop about the arrival time. When the bus stop terminal device 5 obtains arrival times from a plurality of bus routes, the bus stop terminal device 5 obtains arrival time differences and performs a transfer support process according to the arrival time differences. In the transfer support process, for example, the bus-equipped terminal device 3 is controlled to output a transfer ticket with a time limit, as in the above embodiment. The contents of the transfer support may be processing described in another embodiment described later. As in this example, the support function may be provided in the bus stop terminal device 5 or may be appropriately distributed as long as the support function of the bus operation support system 1 can be suitably performed.

  Next, a second embodiment of the present invention will be described. The overall configuration of the second embodiment is the same as that of the first embodiment, and a description of overlapping matters is omitted. In the second embodiment, the control unit 20 of the bus-equipped terminal device 3 includes a transfer support unit that is different from the first embodiment.

The arrival time difference calculation unit 54 calculates the arrival time difference between the own bus to the transfer bus stop and other buses on the transfer bus route, similarly to the same configuration of the first embodiment. The waiting determination unit 56 compares the arrival time difference with a predetermined waiting reference time to determine whether or not the own bus should wait for another bus. The wait command output processing unit 58 refers to the wait command generation information storage unit 52 according to the determination result of the wait determination unit 56 and outputs a wait command. The waiting information notification unit 60 notifies the waiting information to the bus-equipped terminal device of the waiting target bus via the ad hoc network 7. The waiting information includes identification information of the own bus and waiting time information.

  In the present embodiment, the waiting command generation information storage unit 52 stores a waiting command message to be transmitted to the driver in the present embodiment. The wait command message has a content for instructing which bus to wait for how long, for example, a text sentence. In this wait command message, the name of the bus line to be waited for and information on the waiting time are blank.

  The wait command output processing unit 58 refers to its own bus route data, and inserts the name of the transfer bus route passing through the next transfer bus stop into the bus route name of the wait command message. The name of the transfer bus route is included in the own bus route data along with the information of the transfer bus stop.

  Further, the wait command output processing unit 58 inserts a necessary wait time in the wait time column of the wait command message. The required waiting time is a value obtained by adding a predetermined transfer time to the arrival time difference. The predetermined transfer time is fixed. The transfer required time may be set differently for each transfer bus stop. For example, the own bus route data has a transfer required time accompanying the transfer bus stop, and this information is referred to.

  The wait command output processing unit 58 outputs a wait command message from the output unit 18 to the driver. An image including the text of the waiting command may be generated and displayed on the display. Alternatively, a synthesized voice that reads out the text of the waiting command may be generated, and this voice may be output from a speaker.

  FIG. 11 shows the operation of the present embodiment. In FIG. 11, the processing in steps S10 to S14 is the same as that in the first embodiment. That is, the control unit 20 determines whether or not the vehicle has passed the bus stop just before the transfer bus stop based on the current position and the own bus route data (S10). When passing the bus stop just before, the arrival time calculation unit 22 calculates the arrival time to the transfer bus stop based on the current position and the own bus route data (S12). In addition, the arrival time acquisition unit 26 of the arrival time transfer unit 24 acquires the arrival time at the transfer bus stop from the bus-equipped terminal device on the other bus on the transfer bus route through communication via the ad hoc network 7 (S14). ).

  Next, the arrival time difference calculation unit 54 calculates the arrival time difference between the own bus to the transfer bus stop and other buses on the transfer bus route (S30). Here, the arrival time of the own bus is subtracted from the arrival time of other buses. Then, the waiting determination unit 56 compares the arrival time difference with a predetermined waiting reference time to determine whether or not the own bus should wait for another bus (S32). The predetermined waiting reference time is, for example, 3 minutes. If the arrival time difference is within 3 minutes, the wait determination unit 56 determines that the bus on the transfer bus route should be waited (S32, YES).

  When the wait determination unit 56 determines that the bus on the transfer bus route should be waited, the wait command output processing unit 58 refers to the wait command generation information storage unit 52 and outputs a wait command (S34). Here, as described above, a waiting command is generated and output to the driver.

  Further, the wait information notification unit 60 notifies the wait information to the bus-equipped terminal device of the wait target bus via the ad hoc network 7 (S36). Here, information indicating that the own bus is waiting is sent to the bus-equipped terminal device of the transfer bus route that has provided the arrival time. This information includes waiting time information. This information is presented to the driver and passengers at the bus-mounted terminal device of the provider.

  As described above, even with the bus mobile terminal device according to the second embodiment of the present invention, as in the first embodiment, the buses of different bus routes can be linked with each other with a small-scale system. This can be favorably supported.

  The second embodiment determines whether to wait for a bus on the transfer bus route based on the arrival time difference between the own bus to the transfer bus stop and other buses on the transfer bus route, and waits according to the determination result. Therefore, if the difference in arrival time is within an appropriate range, it is possible to operate a bus that waits for another bus, and it is possible to favorably support the transfer of passengers by appropriate operation adjustment.

  Next, a third embodiment of the present invention will be described. The overall configuration of the third embodiment is the same as that of the first embodiment, and a description of overlapping items is omitted. In the third embodiment, the control unit 20 of the bus-equipped terminal apparatus 3 includes a transfer support unit that is different from the first embodiment.

  FIG. 12 shows the configuration of the transfer support unit 70 of the present embodiment. The transfer support unit 70 includes a guidance generation information storage unit 72, an arrival time difference calculation unit 74, and a guidance output unit 76.

  The guidance generation information storage unit 72 stores information for generating guidance for passengers regarding transfer at a transfer bus stop. The arrival time calculation unit 74 calculates the arrival time difference between the own bus to the transfer bus stop and other buses on the transfer bus route, similarly to the same configuration of the first embodiment. The guidance output unit 76 refers to the guidance generation information storage unit 72 and outputs a transfer guidance for passengers including the arrival time difference.

  In the present embodiment, the guidance generation information storage unit 72 stores a transfer guidance message to be transmitted to the passengers in the present embodiment. The transfer guidance message has a content indicating which bus route can be transferred to at the next bus stop, and is, for example, a text sentence. In the transfer guidance message, the name of the next transfer bus stop, the name of the transfer bus route, and the arrival time difference information are blank.

  The guidance output unit 76 refers to the own bus route data, and inserts the name of the next transfer bus stop and transfer bus route into the transfer guidance message. The name of the transfer bus route is included in the own bus route data along with the information of the transfer bus stop. Further, the guidance output unit 76 inserts the arrival time difference information calculated by the arrival time difference calculation unit 74 into the transfer guidance message.

  The guidance output unit 76 performs a process of outputting the transfer guidance message generated in this way for passengers. An image including the text of the transfer guidance message may be generated and displayed on the display. Alternatively, a synthesized voice that reads the text of the transfer guidance message may be generated, and this voice may be output from a speaker. When transfer information is provided, passengers can know how long they can wait to transfer at the next transfer bus stop.

  FIG. 13 shows the operation of the present embodiment. In FIG. 13, the processing in steps S10 to S14 is the same as that in the first embodiment. That is, the control unit 20 determines whether or not the vehicle has passed the bus stop just before the transfer bus stop based on the current position and the own bus route data (S10). When passing the bus stop just before, the arrival time calculation unit 22 calculates the arrival time to the transfer bus stop based on the current position and the own bus route data (S12). In addition, the arrival time acquisition unit 26 of the arrival time transfer unit 24 acquires the arrival time at the transfer bus stop from the bus-equipped terminal device on the other bus on the transfer bus route through communication via the ad hoc network 7 (S14). ).

  Next, the arrival time difference calculation unit 74 calculates the arrival time difference between the own bus to the transfer bus stop and other buses on the transfer bus route (S50). Here, the arrival time of the own bus is subtracted from the arrival time of other buses. And the guidance output part 76 outputs the transfer guidance for passengers with which the arrival time difference was included with reference to the guidance production | generation information storage part 72 (S52). Here, as described above, information such as a difference in arrival time is inserted into a guide prepared in advance.

  As described above, the bus mobile terminal device according to the third embodiment of the present invention also enables the buses of different bus routes to be linked with each other with a small-scale system, as in the first embodiment. This can be favorably supported.

  In addition, since the third embodiment is configured to generate and output a guide for passengers including arrival time differences between the own bus to the transfer bus stop and other buses on the transfer bus route, it includes an arrival time difference. Useful transfer guidance can be provided to passengers to support passenger transfer.

  Next, a fourth embodiment of the present invention will be described. The overall configuration of the fourth embodiment is the same as that of the first embodiment, and a description of overlapping items is omitted. In the fourth embodiment, the control unit 20 of the bus-equipped terminal device 3 includes a transfer support unit that is different from that of the first embodiment.

  FIG. 14 shows a configuration of the transfer support unit 80 of the present embodiment. The transfer support unit 80 includes a support content storage unit 82, an arrival time difference calculation unit 84, a support content selection unit 86, and a support content execution unit 88.

  The support content storage unit 82 stores different transfer support content according to the arrival time difference between the own bus to the transfer bus stop and other buses on the transfer bus route. In the present embodiment, the support content storage unit 82 includes the information in the transfer ticket generation information storage unit described in the first embodiment and the wait command generation information storage unit described in the second embodiment. It stores information. As described with respect to each embodiment, the former is information for generating a transfer ticket with a time limit with a transfer time limit, and the latter is for waiting for another bus on the transfer bus route at the transfer bus stop. This is information for generating a waiting command. As described later, both pieces of support content information are selectively used depending on the arrival time difference based on a predetermined threshold arrival time difference.

  Further, the support content storage unit 82 also stores information on the guidance message of the guidance generation information storage unit described in the third embodiment. As for the guidance message, in addition to the message described in the above embodiment, the support content storage unit 82 waits for a bus on the transit bus route in accordance with a message that guides the issuance of a transfer ticket with a time limit and a wait instruction. The message to guide is also memorized.

  The arrival time difference calculation unit 84 calculates the arrival time difference between the own bus to the transfer bus stop and other buses on the transfer bus route, similarly to the same configuration of the first embodiment.

  The support content selection unit 86 determines a support process to be executed based on the arrival time difference calculated by the arrival time difference calculation unit 88. Here, the support content selection unit 86 compares the arrival time difference with a predetermined threshold arrival time difference. The threshold arrival time difference may be, for example, 3 minutes, similar to the waiting reference time in the third embodiment. If the arrival time difference is less than or equal to the threshold arrival time difference, the support content selection unit 86 selects a wait command output as the support processing. If the arrival time difference exceeds the threshold arrival time difference, the support content selection unit 86 selects the transfer ticket output as the support processing.

  The support content execution unit 88 executes the support content selected by the support content selection unit 86. Thereby, the transfer support unit 80 can execute the process of the transfer support content corresponding to the arrival time difference calculated by the arrival time difference calculation unit 84.

  The support content execution unit 88 includes the function of the transfer ticket output processing unit described in the first embodiment and the function of the wait command output unit described in the second embodiment. The former is a function that outputs a transfer ticket with a time limit in which a transfer time limit of a length corresponding to the calculated arrival time difference is set, and the latter is a function that outputs a waiting command for a driver.

  The support content execution unit 88 also has the function of the guidance output unit described in the third embodiment. This function generates and outputs a message according to the support content selected by the support content selection unit 86 described above. That is, according to the selected support content, the support content execution unit 88 outputs a guide for waiting for a bus on a transfer bus route, and outputs a guide for issuing a transfer ticket with a time limit.

  FIG. 15 shows the operation of the present embodiment. In FIG. 15, the processing of steps S10 to S14 is the same as that of the first embodiment. That is, the control unit 20 determines whether or not the vehicle has passed the bus stop just before the transfer bus stop based on the current position and the own bus route data (S10). When passing the bus stop just before, the arrival time calculation unit 22 calculates the arrival time to the transfer bus stop based on the current position and the own bus route data (S12). In addition, the arrival time acquisition unit 26 of the arrival time transfer unit 24 acquires the arrival time to the transfer bus stop from the bus-equipped terminal device on the other bus on the transfer bus route through communication via the ad hoc network 7 (S14). ).

  Next, the arrival time difference calculation unit 84 calculates the arrival time difference between the own bus to the transfer bus stop and other buses on the transfer bus route (S60). Here, the arrival time of the own bus is subtracted from the arrival time of other buses. Then, the support content selection unit 86 refers to the support content storage unit 84 and selects the transfer support content corresponding to the arrival time difference calculated by the arrival time difference calculation unit 84 (S62).

  Here, if the arrival time difference is less than or equal to the threshold arrival time difference, the support content selection unit 86 selects the wait command output as the support processing. In this case, the support content execution unit 88 outputs a guidance message to the passengers telling that it waits for the bus on the transfer bus route at the transfer bus stop (S64), and issues the wait command described in the second embodiment to the driver. (S66).

  On the other hand, if the arrival time difference exceeds the threshold arrival time difference, the support content selection unit 86 selects the transfer ticket output as the support process in step S62. In this case, the support content execution unit 88 outputs a guide for issuing a transfer ticket with a time limit (S68), and performs the process of outputting the transfer ticket with a time limit described in the first embodiment (S70).

  When the wait command is output in S66 described above, the bus waits for the transfer destination bus at the transfer bus stop by adjusting the waiting time. Even in this case, it is required that passengers' previous boarding information be taken over in order to smoothly carry out the boarding procedure for the bus to which the transfer is made. That is, it is required to be shown as a transit customer. For this purpose, for example, even when a waiting command is output, a transfer ticket with a predetermined minimum time limit is issued.

  As described above, the bus mobile terminal device according to the fourth embodiment of the present invention also enables the buses of different bus routes to be linked with each other with a small-scale system, as in the first embodiment. This can be favorably supported.

  In the fourth embodiment, different transfer support contents are stored according to the arrival time difference between the own bus to the transfer bus stop and other buses on the transfer bus route, and the transfer support corresponding to the calculated arrival time difference is stored. Since the processing of the contents is executed, it is possible to suitably support the passenger transfer by performing an appropriate transfer support process according to the arrival time difference.

  The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above-described embodiments, and it goes without saying that those skilled in the art can modify the above-described embodiments within the scope of the present invention.
