Description

  The present invention makes it possible for a bus user to transmit an indication of the intention of boarding a bus to an operating bus in the vicinity of the bus stop. The present invention relates to a bus operation system that can be obtained by a user, and a bus operation management device and a portable communication device used for the bus operation system.

  Bus users who wish to take a local bus head on the way from their home, station, etc. to the bus stop by walking. In this case, the bus user may or may not know the scheduled bus departure time at the boarding bus stop. It is common for bus users who know the scheduled departure time of the bus to go to the bus stop with a time margin, and even if the bus user who does not know the scheduled departure time of the bus has no other special purpose If you do, you will head to the bus stop. Even in such a case, the bus driver is not in time for the scheduled departure time of the bus due to some situation, and the bus driver is in the bus user's view, but the driver of the bus There are many cases where the user leaves the bus stop without recognizing the user and leaving the bus user. In such a case, the bus user will feel unpleasant.

  In addition, the route bus service is greatly affected by the traffic conditions on the road. In particular, in urban areas, the number and types of vehicles passing through the road are large, and in addition, there are many cases of chronic traffic congestion throughout the day due to road regulations due to road construction and traffic accidents. For this reason, regular buses that operate regularly depend on the degree of traffic congestion and cannot depart from the designated bus stop on time, and arrive or depart from the bus stop several tens of minutes after the on time. Not a few. In such a case, some users who arrive at the bus stop after the scheduled bus departure time think that the bus at the scheduled bus departure time has already left the bus stop, and consider the next arrival time of the next bus. Some users choose to walk on the way to the next bus stop. In this case, the user heading for the next bus stop is overtaken by the bus just before the arrival at the next bus stop and eventually cannot get on the bus at the next bus stop, or to the next bus stop. Even if the user who headed for the bus noticed the bus that arrived at the bus stop late for the scheduled departure time and returned to the original bus stop, it might not be in time for the bus.

  In this way, problems related to boarding between bus users and operating buses are frequent occurrences, and the bus users are able to board the bus more smoothly and as much as possible. There is a need to develop a bus operation system that can achieve this.

  Under such circumstances, for the purpose of notifying the bus users of the correct operation of the bus, there is a known bus operation system in which a display showing the location information of the bus is installed at the bus stop to make it easier for the user. (See Patent Document 1).

In this bus operation system, when the bus approaches the bus stop, the bus approach is displayed, and an indicator for notifying the bus user of the bus location information is provided at the bus stop. A transmission means is provided for transmitting the location information of the bus to the bus operation management center via a public wireless network. The bus operation management center transmits the received bus position information to the pager terminal installed at the bus stop, and the bus stop displays the bus position information received by the pager terminal on the display means. With such a display, at least the bus user waiting at the bus stop can determine how close the bus is to the bus stop or whether the bus has already departed from the bus stop. It can be done easily. Accordingly, the bus user can easily determine a more correct choice regarding the boarding of the bus, for example, whether to wait for a while at the bus stop or go to the next bus stop on foot.
JP 2001-256597 A

  In the conventional bus operation system described above, since the bus stop is equipped with an indicator for notifying the bus position information, only bus users waiting at the bus stop are concerned with bus arrivals and departures at the bus stop. Information can be acquired. In other words, according to this bus operation system, the convenience for the bus user is only to provide the bus user standing by at the bus stop with the location information of the buses to / from the bus stop. In other words, no convenience is given to those who wish to board the bus near the bus stop. In other words, as described above, some bus users may not be in time for the scheduled departure time of the bus due to some circumstances, but there are users who have a bus stop at the bus stop or a bus operating in the vicinity. Although the bus is not in sight, there is a user who can arrive at the bus stop in a short time, but the bus driver does not notice such a bus user and wants to ride the bus Currently, no bus operation system has been developed that provides any solution to the situation where the bus departs from the bus stop without leaving the driver.

  The present invention has been made in view of the above points, and at least in the vicinity of a bus stop, a person who wants to take a bus is operating on or near the bus that is stopping at the bus stop. And a bus operation system that enables a person who wants to get on the bus to obtain information on whether or not to get on the intention to ride the bus. An object of the present invention is to provide a bus operation management device and a portable communication device.

  Passengers who wish to get on a bus that stops at a bus stop or a bus that is running in the vicinity of the bus stop can communicate the intention indication of the ride request by radio, and further, whether or not the passenger can board the will indication ( (Acceptance or refusal) messages can be received, so that troubles related to bus rides and irritation of bus users can be alleviated to some extent.

  Hereinafter, a bus operation system according to an embodiment of the present invention will be described. FIG. 1 shows an example of the operation status when the bus operation system according to the present embodiment is used. As the operational status of FIG. 1, the bus rider 1 catches the bus 3 stopped at the bus stop 2 in the field of view, but the driver 4 of the bus 3 does not recognize the bus rider 1, A case will be described in which it is assumed that the bus departs from the bus stop 2 while leaving the bus rider 1, and the bus rider 1 transmits the intention (hope) to ride to the driver 4.

  As will be described later, in such a case, the bus rider 1 has a portable communication device 5 (described later), and has shown his intention to get on the bus 3 stopped via the communication device 5. A signal (a ride request signal) is transmitted. Based on the boarding request signal from the bus rider 1, the driver 4 of the bus 3 continues to stop until the boarder 1 rides, or depending on the current operation status, A request for boarding 1 is carefully refused, it is determined whether or not the vehicle should be departed immediately, and a signal (boarding permission / rejection signal) indicating whether or not boarding is possible is transmitted to the user 1 who wants to board. Based on this signal, it is possible to confirm whether or not the rider 1 can get on the currently stopped bus. Judgment of permission / rejection of boarding may be made based on the subjectivity of the driver 4, but may be made in consideration of automatic judgment processing as described later.

  Specific operation devices and operation methods for realizing the bus operation system according to the present embodiment as described above will be described in detail below with reference to the accompanying drawings.

  FIG. 2 is a block diagram showing an outline of the boarding availability determination / notification device 6 provided in each bus in order to realize the bus operation system according to the present embodiment.

  Each bus 3 includes a communication means (radio device) 8 for receiving a ride request signal from the communication device 5 of the bus rider 1 via the antenna 7. The reception means (ride request signal) is input from the communication means 8 and whether to permit or reject the ride of the bus rider 1 who has sent the ride request signal according to the current bus operation status is automatically determined. Control means 9 for determining automatically, position detection means 10 including GPS for detecting the current position of the self, the current position of the self detected by the position detection means 10 and the current position of the rider 1 For example, a display unit 11 that displays on a display screen centered on its current position, and a message generation unit 12 that generates a predetermined message for the passenger 1 based on the processing result of the control unit 9. Preparation It is. The communication means 8 is capable of bidirectional communication with the communication device 5 of the bus rider 1 and has reception and transmission functions. As such communication means 8 and communication means provided in the communication device 5 of the bus rider 1, for example, a wireless LAN transceiver may be used. Accordingly, the communication means 8 is configured not only to receive the boarding request signal from the rider who desires 1 but also to transmit the message from the message generator 12 toward the rider who wants to ride. Further, processing performed by the control means 9 (position detection of the passenger who wants to ride, recognition of the current bus operation status, determination of boarding permission / rejection for the boarding desire signal, message creation instruction to the passenger who wants to ride, etc.) will be described later. . Further, a map around the current position of the bus may be displayed on the display screen of the display means 11 as a background.

  On the other hand, FIG. 3 is a block diagram showing a basic structure of the communication device 5 possessed by each rider (bus user) 1. The communication device 5 includes a communication unit 13 capable of bidirectional communication with each bus via an antenna, a position detection unit 14 having a GPS for detecting its own position, and current position information detected by the position detection unit 14. And a control means 15 for generating a boarding request signal including information indicating the desire to board the bus and transmitting the signal to the bus 3 via the communication means 13.

  Next, the processing performed by the control means 9 (recognition of the position of the passenger who wishes to ride, recognition of the current bus operation status) when the bus rider wants a boarding signal to be transmitted to the bus 3 stopped at the bus stop 2 Next, the boarding permission / rejection determination with respect to the boarding request signal, message creation instruction to the boarding requester, etc.) will be described based on the flowchart of FIG.

  FIG. 4 shows that after receiving a ride request signal from the rider 1, the rider 1 is permitted to board (from the rider 1 admitting the rider 1 until the rider 1 actually gets on the bus. Judgment / notification of getting on / off until sending a signal indicating that the vehicle will stop) or refusal of boarding (determined from current bus operation status and cannot wait for boarding by rider 1) 7 is a flowchart showing a boarding permission / rejection determination process performed by a control means 9 in the device 6.

  The boarding permission / rejection determination process can be started by manual operation of a switch or the like by a bus driver, or by automatic control accompanying engine start or the like, and is not particularly limited. Further, the boarding permission / rejection determination process is in a standby state until a boarding request signal from the boarding applicant 1 is received. If a boarding request signal is received (S1), the current position PP of the boarding person 1 included in the boarding request signal is detected (S2). Further, the current position BP of the bus is detected based on the position information obtained by the position detecting means 10 (S3). Here, based on the current position PP of the passenger 1 and the current position BP of the bus, the boarding permission / rejection for the passenger 1 is determined. In this case, for example, the distance (D) between PP and BP, that is, the distance D between the passenger 1 and the bus that is stopped at the bus stop (or the bus that is running near the bus stop) is obtained (S4). ), Used to determine whether to accept or reject boarding.

  The determination of boarding permission / rejection is based on the distance D described above and a threshold (DT) set according to the current operation status of the bus (delay status from the scheduled departure time due to road traffic conditions, etc.). The comparison is performed (S5). For example, when the bus operation status has some time allowance, the threshold value DT is set to a large value, but there is no time allowance (the operation status is considerably delayed in time). The threshold value DT is set to a small value. In addition, in determining whether to permit or reject the boarding, in addition to the threshold value DT calculated from the distance D and the driving situation described above, the boarding permission / rejection is also considered in consideration of the road conditions around the bus stop, road topography, and the like. A determination may be made. Depending on the current position of the rider 1, it is not possible to simply rely on the straight distance to the bus (that is, the road from the rider 1 to the bus stop is not always a straight line, and the twists and turns) It is possible to make a more accurate determination by making a boarding permission / rejection determination in consideration of these road conditions and the like. The operation status can be grasped automatically by installing a storage device in the boarding determination / notification device 6, calculating the operation time and boarding status by the control means 9 at regular intervals, and recording and updating these data. Done. Further, by analyzing the surrounding map data based on the current position from the position detecting means 10, the road condition can be automatically grasped to some extent.

  If it is determined by comparison between the distance D and the threshold value DT that the passenger 1 is within the threshold DT (YES: S5), a signal for permission of boarding (1) OK message) is transmitted (S6). If it is determined that the passenger 1 is located outside the threshold DT (NO: S5), a boarding refusal signal (NG message) is immediately transmitted to the passenger 1 (S7). At this time, a message is created by the message generating means 12 and transmitted to the rider who wants to get on board 1. In particular, regarding the message in the case of a boarding refusal, considering the rider's feelings, the message should be as polite as possible. It is preferable to notify by text or voice. After transmitting the boarding permission / rejection signal, the system waits until a boarding request signal is received again (S1). Note that characters, sounds, images, and the like are used as messages.

  Simultaneously with the boarding permission / rejection determination process shown in FIG. 4, the processing results are displayed on the display means 11 provided on the bus. This display example will be described with reference to FIGS.

  A display device such as a monitor is provided near the bus driver. When a ride request signal is received from the rider 1, a mark indicating the current position of the rider 1 lights (flashes) on the screen. . The current position of the bus is always set at the center of the display device. A map around the bus may be displayed in the background of the display device. As a result, even if the bus user who wants to ride is in a position that cannot be seen by the bus driver, the bus driver 4 not only knows the presence of the passenger who wants to ride, but only by looking at the display device. Can be recognized at a glance. In FIG. 5, the reception range of the boarding desired signal and the boarding allowable range are shown on the screen of the display device, and the position of the bus rider 1 is shown on this screen (the center of the screen is the current bus status). Position (stop position)). The boarding allowable range may be set automatically by the control means 9 or may be set manually by judgment of the bus driver.

  Note that the screen of FIG. 5 shows that there is one rider who is within the boarding allowable range, and that there is one rider who is outside the boarding allowable range. From this screen, the bus driver selects a predetermined message, such as “Wait for a while”, for a rider who is within the boarding tolerance range (distance PP1 from the bus position) and gets this message. It transmits to the applicant (FIG. 6). For those who wish to ride outside the permissible boarding range (distance PP2 from the bus position), select a specific message, for example, “Due to a significant delay in operation time” or “Cannot board any more due to full capacity”. This message is transmitted to the rider (FIG. 7). Note that the message selection and transmission are manually performed by the bus driver, but may be performed automatically by the determination of the control means 9. In addition, a message is selected and transmitted only to those who wish to ride within the allowable boarding range, but for those who wish to ride outside the allowable boarding range, the first message of the preset “NG message” is displayed. It may be transmitted automatically.

  These messages are output by providing a speaker or a display device on the communication device of the rider.

  5 to 7, the threshold value DT is set such that the threshold value DT is positioned on the circumference with the bus position as the center (the allowable boarding range is circular). That is, the threshold value DT is determined according to the operation status (operation time, traffic status, etc.). On the other hand, when the threshold value DT is determined in consideration of the road topography around the bus position, the boarding allowable range may be a complicated shape other than the circular shape.

  As shown in FIG. 5, when a plurality of riders simultaneously send a ride request signal to a bus stop or a nearby bus, which rider wishes to send a boarding permission / reject message. Is located in the boarding allowable range, and it is necessary to identify which boarding candidate is located outside the boarding allowable range. For example, identification information is incorporated in advance in a communication device of each passenger who wants to ride, and this identification information is automatically added to the boarding desired signal and transmitted at the stage of sending the boarding desired signal. May be. In this case, the bus side performs a boarding permission / rejection determination process for each piece of identification information, and further transmits a boarding permission / rejection message to the passenger who wishes to ride (for example, boarding permission / rejection). By adding the identification information to the rejection message and transmitting the message, only the communication device having the identification information may be able to read the message.

  Therefore, even if a plurality of riders desire to send a ride request signal at the same time, the bus can identify each rider and send an accurate boarding permission / rejection message.

  In the embodiment described above, when there is only one bus that receives a boarding request signal from a passenger who wants to ride, that is, there is only one bus within a range in which the boarding request signal can be received (near the bus stop). The case where no other bus exists) has been described. However, especially in places where buses with different routes are frequently operated, such as in urban areas, bus stops with different routes are often installed in close proximity. In such a case, multiple buses with different routes stop at multiple bus stops that are installed in close proximity or are running near these bus stops, and multiple passengers wishing to board these buses May send a ride request signal at approximately the same time. In such a case, the boarding availability determination / notification device 6 provided in each bus also displays on the display means 11 a person who wants to board the bus (current position) who does not wish to board the bus. Therefore, the person who wants to get on the bus will receive a signal for permitting / rejecting the boarding from a plurality of buses that do not want to get on the bus, and it is difficult to know whether the bus that he / she wants to get on can actually get on. In order to avoid such a mixed line state, it is conceivable to assign specific identification information (route identification information) different for each route to each bus. In this case, the portable communication device possessed by the rider who wishes to board the bus on a specific route includes the identification information assigned to this route in the ride request signal, and rides via the communication means. It is transmitted to a plurality of buses including the desired bus. At this time, only the bus to which the identification information is assigned receives the boarding request signal from the rider based on the identification information, and performs the above-described boarding request permission / rejection process. In other words, only the bus that wants to board receives the boarding request signal from the person who wants to board the bus, performs the boarding request permission / rejection process, and returns the boarding request permission / rejection signal only to the person who wants to ride can do. Therefore, it is possible to avoid the mixed line state as described above.

  In the embodiment described above, the bus that receives the boarding request signal is not limited to the bus that is stopped at the bus stop, and includes a bus that is in the vicinity of the bus stop. In the case of the latter, for example, even if there is no bus immediately after departure, or a bus that passes without stopping at the bus stop because there is no bus stop, send a ride request signal as in this embodiment This is because the bus stops. Here, “near” is a range in which a bus stop including a bus stop is commonly accepted, but within a range in which a boarding request signal from a rider can be received.

  In the embodiment described above, each bus user and the communication means provided in each bus communicate directly with each other via a wireless LAN or the like without going through another relay. On the other hand, each bus stop may be provided with a repeater for receiving a ride request signal from a bus user and transmitting the ride request signal to a bus located in the vicinity of the bus stop. In addition, when a plurality of bus stops are installed close to each other, an identification number is assigned to each bus stop. In this case, the identification number assigned to the bus stop to be boarded is added to the boarding request signal transmitted from the bus user side, and transmitted to the bus stop.

An example of the operation situation in the case of using the bus operation system concerning this embodiment is shown. FIG. 2 is a block diagram illustrating an outline of a boarding availability determination / notification device provided in each bus in order to realize the bus operation system according to the present embodiment. It is the block diagram which showed the basic structure of the communication apparatus which each boarding applicant (bus user) has. It is the flowchart which showed the process performed by a control means when a boarding request signal is transmitted to the bus by the bus rider. 6 is a display example of a processing result of the boarding permission / rejection determination processing shown in FIG. 4 displayed on the screen of the display device. FIG. 6 is a display example showing a person who wants to ride within a boarding allowable range and a transmission message during the display of FIG. 5. FIG. 6 is a display example showing a rider who is outside the boarding allowable range and a transmission message during the display of FIG. 5.
