Description

[Technical field]

[0001] The present invention relates to a management device for shuttle vehicles and a management method for shuttle vehicles. [Background technology]

[0002] There is known a system that determines whether or not there is a person in a vehicle based on the vehicle weight (see, for example, Patent Document 1). In the system described in Patent Document 1, the presence or absence of a person in a vehicle is determined based on whether or not the difference between the weight of the vehicle when it is entered into the platform of a multi-story parking lot and the weight of the vehicle when it is subsequently loaded onto the platform is within a preset range. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2005-200892 A Summary of the Invention [Problem to be solved by the invention]

[0004] Let us consider a case where, based on the vehicle weight, it is confirmed that passengers who are to be picked up or dropped off, such as children, who are on a shuttle vehicle such as a shuttle bus for a kindergarten or nursery school, etc., have disembarked. In this case, since the number of passengers to be picked up or dropped off is unspecified, it is not possible to confirm that all passengers to be picked up or dropped off have disembarked based on the difference in vehicle weight before and after the passengers to be picked up or dropped off.

[0005] In consideration of the above circumstances, the present invention aims to provide a shuttle vehicle management device and a shuttle vehicle management method that can confirm whether passengers being picked up or dropped off by the shuttle vehicle have disembarked based on the weight or load of the vehicle. [Means for solving the problem]

[0006] The shuttle vehicle management device of the present invention is a shuttle vehicle management device that is equipped with a judgment unit that judges whether a passenger to be picked up and dropped off who is on the shuttle vehicle should disembark or continue to ride based on the measurement value of a weight sensor that measures the weight or load of the shuttle vehicle, and the judgment unit judges that the passenger should continue to ride if the difference between a first value, which is the measurement value of the weight sensor before the passenger boards the shuttle vehicle or a zero value obtained by resetting the measurement value to zero, and a second value, which is the measurement value of the weight sensor after the passenger disembarks from the shuttle vehicle, is greater than or equal to a first predetermined value, and judges that the passenger should disembark if the difference between the first value and the second value is less than the first predetermined value.

[0007] The method for managing a shuttle vehicle of the present invention is carried out using a judgment device that judges whether a passenger who is to be shuttled and is aboard the shuttle vehicle should disembark or continue to ride based on the measurement value of a weight sensor that measures the weight or load of the shuttle vehicle, and if the difference between a first value, which is the measurement value of the weight sensor before the passenger boards the shuttle vehicle or a zero value obtained by resetting the measurement value to zero, and a second value, which is the measurement value of the weight sensor after the passenger disembarks from the shuttle vehicle, is greater than or equal to a first predetermined value, it is judged that the passenger should continue to ride, and if the difference between the first value and the second value is less than the first predetermined value, it is judged that the passenger should disembark. Effect of the Invention

[0008] According to the present invention, it is possible to confirm whether a passenger to be picked up or dropped off from a shuttle vehicle has disembarked based on the weight or load of the shuttle vehicle. [Brief description of the drawings]

[0010] The present invention will be described below along with preferred embodiments. Note that the present invention is not limited to the embodiments shown below, and the embodiments shown below can be modified as appropriate within the scope of the present invention. In addition, in the embodiments shown below, some configurations are omitted from illustration and description, but for the details of the omitted technologies, publicly known or well-known technologies are applied as appropriate within the scope of no contradiction with the contents described below.

[0011] Fig. 1 is a block diagram showing an operation control system 1 according to one embodiment of the present invention. The operation control system 1 shown in this figure has a determination function for determining whether a child on a kindergarten or nursery school shuttle bus gets off or continues to ride (so-called "forgotten to get off").

[0012] The operation management system 1 includes an in-vehicle device 10 and a weight sensor 20. The in-vehicle device 10 includes a CPU (Central Processing Unit) 11, a memory 12, an interface (I / F) 13, and an alarm 14. The CPU 11, in accordance with a program stored in the memory 12, determines whether the children should get off or continue riding on the bus, based on the load of the bus measured by the weight sensor 20.

[0013] The memory 12 is a non-volatile memory such as a RAM (Read And Memory), an SSD (Solid State Drive), an HDD (Hard Disc Drive), etc. The memory 12 stores programs executed by the CPU 11, data used by the programs, data generated by the execution of the programs, etc.

[0014] The interface 13 is connected to the weight sensor 20, the navigation system 30, the ignition switch 40, etc. The interface 13 receives inputs of the measurement value of the weight sensor 20, the position information of the navigation system 30, the ON / OFF signal of the ignition switch 40, etc. Furthermore, the interface 13 transmits warning information to a management server (not shown) of the operation management system 1 when the CPU 11 determines that children are continuing to board the shuttle bus.

[0015] The alarm 14 is a buzzer, lamp, display screen, etc. installed inside or outside the vehicle, and is activated by the CPU 11 if there are children remaining in the shuttle bus after the bus has returned to the departure point, and warns the driver inside the vehicle and relevant parties outside the vehicle with a sound, light, warning display, etc.

[0016] The weight sensor 20 measures the load of the shuttle bus and outputs the measurement value to the vehicle-mounted device 10. An example of the weight sensor 20 is a load meter that calculates the load based on the distortion of the rear axle or front axle measured by a distortion sensor provided on the rear axle or front axle. Note that the weight sensor 20 does not necessarily have to be a load meter that measures the load of the shuttle bus, and may be a platform weight that measures the total weight of the shuttle bus, a weighing scale that measures the weight of the passenger cars of the shuttle bus, or the like. When the weight sensor 20 is a platform weight, the platform weight may be installed in the parking spaces that are the departure and arrival points of the shuttle bus.

[0017] The CPU 11 includes a first measuring unit 111, a second measuring unit 112, a determination unit 113, and an alarm control unit 114. The first measuring unit 111 obtains a measurement value of the weight sensor 20 at the departure point of the shuttle bus and stores it in the memory 12.

[0018] For example, when the first measuring unit 111 receives an ON signal from the ignition switch 40 and the current position of the shuttle bus measured by the navigation system 30 coincides with the position of the parking space for the shuttle bus, the first measuring unit 111 acquires the measurement value of the weight sensor 20 and stores it in the memory 12. Note that an operation button (not shown) that is operated by the driver when the shuttle bus starts to operate may be provided on the vehicle-mounted device 10, and when the operation button is operated, the first measuring unit 111 acquires the measurement value of the weight sensor 20 and stores it in the memory 12.

[0019] Here, the first measuring unit 111 may reset the measurement value of the weight sensor 20 to zero at the departure point of the shuttle bus, so that thereafter, the measurement of the weight sensor 20 is performed based on the zero value.

[0020] The second measurement unit 112 acquires the measurement value of the weight sensor 20 at the return point of the shuttle bus and stores it in the memory 12. For example, when the current position of the shuttle bus measured by the navigation system 30 coincides with the position of the parking space of the shuttle bus, the second measurement unit 112 acquires the measurement value of the weight sensor 20 and stores it in the memory 12. Note that an operation button that is operated by the driver when the shuttle bus finishes traveling may be provided on the vehicle-mounted device 10, and when the button is operated, the second measurement unit 112 acquires the measurement value of the weight sensor 20 and stores it in the memory 12.

[0021] Here, if the weight sensor 20 is reset to 0 before the departure of the shuttle bus, the weight sensor 20 measures the loaded weight which increases or decreases from a value of 0. Therefore, the measurement value of the weight sensor 20 acquired by the second measuring unit 112 after the shuttle bus returns is a value which increases or decreases from the value of 0 before the departure.

[0022] After the shuttle bus returns, the determination unit 113 calculates the difference (hereinafter, weight difference) between the measurement value of the weight sensor 20 at the departure point stored in the memory 12 and the measurement value of the weight sensor 20 at the return point stored in the memory 12. If the calculated weight difference is equal to or greater than a predetermined value ΔW1, the determination unit 113 determines that the children should continue riding, and if the calculated weight difference is less than the predetermined value ΔW1, it determines that all the children should disembark.

[0023] Here, the predetermined value ΔW1 is set to a value smaller than the average weight of the children (e.g., 18 kg), such as 10 kg. In other words, if even one child remains on the shuttle bus, the weight difference calculated by the determination unit 113 becomes equal to or larger than the predetermined value ΔW1.

[0024] In the case where the weight sensor 20 is reset to 0 before the departure of the shuttle bus, after the shuttle bus returns, the determination unit 113 calculates the difference between the 0 value and the measurement value of the weight sensor 20 at the return point stored in the memory 12 by the second measurement unit 112. Note that the first measurement unit 111 may store the 0 value before departure in the memory 12, and the determination unit 113 may calculate the difference between the 0 value at the departure point stored in the memory 12 by the first measurement unit 111 and the measurement value of the weight sensor 20 at the return point stored in the memory 12 by the second measurement unit 112.

[0025] The alarm control unit 114 activates the alarm 14 when the determination unit 113 determines that the children will continue to ride. Furthermore, when the determination unit 113 determines that the children will continue to ride, the alarm control unit 114 transmits alarm information to the management server of the operation management system 1 via the interface 13. Note that, when the determination unit 113 determines that all the children have disembarked, the alarm control unit 114 may display information indicating that the children will not continue to ride on an in-vehicle display device or transmit the information to the management server of the operation management system 1.

[0026] Fig. 2 is a diagram for explaining the operation status of shuttle bus B, the operation of which is managed by the operation management system 1 shown in Fig. 1. Fig. 3 is a flowchart for explaining the processing of the operation management system 1 shown in Fig. 1.

[0027] As shown in FIG. 2, first, the driver D gets on the shuttle bus B parked in a predetermined parking space. The driver D who gets on the shuttle bus B turns on the ignition switch 40. As shown in the flowchart of FIG. 3, the first measurement unit 111 of the CPU 11 receives an ON signal from the ignition switch 40 and judges whether or not the current position of the shuttle bus measured by the navigation system 30 coincides with the position of the parking space of the shuttle bus (step S1). If a positive judgment is made in step S1, the first measurement unit 111 acquires the measurement value of the weight sensor 20 and stores it in the memory 12 (pre-departure measurement in step S2). As described above, an operation button for notifying the start of operation may be provided on the vehicle-mounted device 10, and when the first measurement unit 111 receives an ON signal from the operation button and the current position of the shuttle bus measured by the navigation system 30 coincides with the position of the parking space of the shuttle bus, the measurement value of the weight sensor 20 may be acquired and stored in the memory 12. Furthermore, the first measuring unit 111 may reset the measurement value of the weight sensor 20 to 0 when it receives an ON signal from the ignition switch 40 or an ON signal from an operation button.

[0028] As shown in FIG. 2, shuttle bus B departs from the specified parking space and returns to the specified parking space via boarding points scattered around, such as children's homes and meeting places. Shuttle bus B stops at each boarding point, and children board shuttle bus B at the boarding points. Shuttle bus B stops at kindergartens and nursery schools, and children get off at the kindergartens and nursery schools. At this time, there is a possibility that children may remain on shuttle bus B, i.e., they may be forgotten to be dropped off.

[0029] As shown in the flowchart of FIG. 3, the second measurement unit 112 of the CPU 11 receives an OFF signal from the ignition switch 40 and determines whether the current position of the shuttle bus measured by the navigation system 30 matches the position of the parking space of the shuttle bus (step S3). If a positive determination is made in step S3, the second measurement unit 112 acquires the measurement value of the weight sensor 20 and stores it in the memory 12 (measurement after return in step S4). As described above, an operation button for notifying the end of operation may be provided on the vehicle-mounted device 10, and when the second measurement unit 112 receives an ON signal from the operation button and the current position of the shuttle bus measured by the navigation system 30 matches the position of the parking space of the shuttle bus, the second measurement unit 112 may acquire the measurement value of the weight sensor 20 and store it in the memory 12.

[0030] Next, the determination unit 113 of the CPU 11 calculates the difference (weight difference) between the measured value or zero value of the weight sensor 20 before departure stored in the memory 12 and the measured value of the weight sensor 20 after arrival stored in the memory 12, and determines whether the calculated weight difference is equal to or greater than a predetermined value ΔW1 (step S5). If the weight difference calculated in step S5 is equal to or greater than the predetermined value ΔW1 (YES in step S5), the alarm control unit 114 of the CPU 11 activates the alarm 14 (step S6). The alarm control unit 114 may transmit the alarm information to the management server of the fleet management system 1.

[0031] If the weight difference calculated in step S5 is less than the predetermined value ΔW1 (NO in step S5), the process shown in the flowchart in Fig. 3 ends. Note that, if the weight difference calculated in step S5 is less than the predetermined value ΔW1, the warning control unit 114 may transmit information notifying that all the children have disembarked or information indicating the end of the trip to the management server of the traffic management system 1.

[0032] As described above, in the operation management system 1 according to this embodiment, if the difference between the measurement value of the weight sensor 20 before the children board the shuttle bus B or the zero value (first value) obtained by resetting the measurement value to zero and the measurement value (second value) of the weight sensor 20 after the children get off the shuttle bus B is equal to or greater than a predetermined value ΔW1, the CPU 11 determines that the children should continue to board the bus, and if the difference between the first value and the second value is less than the predetermined value ΔW1, it determines that all the children have disembarked. This makes it possible to confirm that all the children have disembarked after they have disembarked, even if the number of children boarding the shuttle bus B is unspecified.

[0033] Furthermore, in the operation management system 1 according to this embodiment, if the difference between the measurement value of the weight sensor 20 at the departure point of the shuttle bus B or a zero value (first value) obtained by resetting the measurement value to zero, and the measurement value (second value) of the weight sensor 20 at the return point of the shuttle bus B, is equal to or greater than a predetermined value ΔW1, the CPU 11 determines whether the children should continue riding. This makes it possible to determine whether the children should continue riding based on the difference in the load or vehicle weight of the shuttle bus B between the time before the children boarded the shuttle bus B and the time after the children disembarked from the shuttle bus B.

[0034] Here, a measurement error of the weight sensor 20 may occur depending on the condition of the road surface such as a slope, unevenness, or steps. Therefore, when the starting point and the return point of the shuttle bus B are different in position, a difference may occur between the load weight or vehicle weight of the shuttle bus B before the children board and the load weight or vehicle weight of the shuttle bus B after the children get off due to the influence of the measurement error of the weight sensor 20. Therefore, in the operation management system 1 according to this embodiment, the starting point and the return point of the shuttle bus B are set to the same parking space, thereby reducing the influence of the measurement error of the weight sensor 20. Therefore, the load weight or vehicle weight of the shuttle bus B before the children board and the load weight or vehicle weight of the shuttle bus B after the children get off can be stably measured, and it can be reliably determined whether the children continue to board or get off.

[0035] In addition, shuttle bus B travels a relatively short distance during each trip, does not change drivers midway, and has a small change in fuel. Therefore, the change in the vehicle weight of shuttle bus B before departure and after returning is only a slight decrease, and does not increase. Therefore, if the vehicle weight of shuttle bus B after returning has increased compared to before departure, it can be determined that a child was left behind.

[0036] Fig. 4 is a block diagram showing a traffic control system 1A according to another embodiment of the present invention. The traffic control system 1A shown in this figure is intended for traffic control of shuttle buses such as express buses and night buses, on which passengers get off at rest points along the way and then get back on again. The traffic control system 1A aims to be able to confirm, based on the measured value of the weight sensor 20, that passengers who get off the shuttle bus at the rest points do not continue to get off (so-called "forgotten to get on"), and is provided with a determination function for determining whether passengers who get off the shuttle bus continue to get on or off.

[0037] The traffic management system 1A may have the function of this embodiment of determining whether a passenger has been forgotten to be picked up in addition to the function of the traffic management system 1 of the above embodiment of determining whether a passenger has been forgotten to be dropped off, and may have the function of this embodiment of determining whether a passenger has been forgotten to be picked up in place of the function of the traffic management system 1 of the above embodiment of determining whether a passenger has been forgotten to be dropped off. Also, the same reference numerals are used for configurations similar to those of the above embodiment, and the explanation of the above embodiment is used.

[0038] The operation management system 1A includes an in-vehicle device 10A and a weight sensor 20. The in-vehicle device 10A includes a CPU 11A, a memory 12, an interface 13, and an alarm 14. The CPU 11A determines whether passengers should continue to board or disembark based on the load of the shuttle bus measured by the weight sensor 20 in accordance with a program stored in the memory 12.

[0039] The CPU 11A includes a third measurement unit 115, a fourth measurement unit 116, a determination unit 117, and an alarm control unit 118. The third measurement unit 115 acquires the measurement value of the weight sensor 20 from when the shuttle bus stops at the rest point until the passengers get off, and stores the measurement value in the memory 12.

[0040] For example, when the third measurement unit 115 receives an OFF signal from the ignition switch 40 and the current position of the shuttle bus measured by the navigation system 30 coincides with the position of a preregistered rest point, the third measurement unit 115 acquires the measurement value of the weight sensor 20 and stores it in the memory 12. Here, the third measurement unit 115 may reset the weight sensor 20 to 0 at the shuttle bus's rest point so that the measurement of the weight sensor 20 is performed based on the 0 value. In addition, the third measurement unit 115 may acquire the measurement value of the weight sensor 20 and store it in the memory 12 when the driver operates an operation button (not shown) for notifying a management server (not shown) of the traffic management system 1A that the shuttle bus has started to take a rest break.

[0041] The fourth measurement unit 116 acquires the measurement value of the weight sensor 20 from when the passenger gets on the shuttle bus that has stopped at the rest point until the shuttle bus departs from the rest point, and stores the measurement value in the memory 12. For example, when the fourth measurement unit 116 receives an ON signal from the ignition switch 40, the fourth measurement unit 116 acquires the measurement value of the weight sensor 20 and stores it in the memory 12. Note that the fourth measurement unit 116 may acquire the measurement value of the weight sensor 20 and store it in the memory 12 when the driver operates an operation button for notifying the management server of the traffic management system 1A that the shuttle bus has finished taking a break.

[0042] Here, if the weight sensor 20 is reset to 0 before the passenger gets off, the weight sensor 20 measures the load weight which increases or decreases from the value 0. Therefore, the measurement value of the weight sensor 20 acquired by the fourth measuring unit 116 after the passenger gets on is a value which increases or decreases from the value 0 before the passenger gets off.

[0043] After the disembarking passenger gets on, the determination unit 117 calculates the difference (hereinafter, weight difference) between the measurement value of the weight sensor 20 stored in the memory 12 by the third measurement unit 115 at the time before the passenger gets off and the measurement value of the weight sensor 20 stored in the memory 12 by the fourth measurement unit 116 at the time after the passenger gets on. If the calculated weight difference is equal to or greater than a predetermined value ΔW2, the determination unit 117 determines that the passengers should continue to disembark, and if the calculated weight difference is less than the predetermined value ΔW2, it determines that all passengers should get on.

[0044] Here, the predetermined value ΔW2 is set to a value smaller than the average weight of a child, such as 10 kg. In other words, if even one passenger remains outside the vehicle, the weight difference calculated by the determination unit 117 becomes equal to or larger than the predetermined value ΔW2.

[0045] In the case where the weight sensor 20 has been reset to 0 before the passenger gets off, the determination unit 117 calculates the difference between the 0 value and the measurement value of the weight sensor 20 stored in the memory 12 by the fourth measurement unit 116 after the passenger gets on. Note that the third measurement unit 115 may store the 0 value before the passenger gets off in the memory 12, and the determination unit 117 may calculate the difference between the 0 value stored in the memory 12 by the third measurement unit 115 and the measurement value of the weight sensor 20 stored in the memory 12 by the fourth measurement unit 116.

[0046] The alarm control unit 118 activates the alarm 14 when the determination unit 117 determines that the passengers will continue to disembark. Furthermore, when the determination unit 117 determines that the passengers will continue to disembark, the alarm control unit 118 transmits alarm information to the management server of the traffic management system 1A via the interface 13. Note that, when the determination unit 117 determines that all passengers have boarded the vehicle, the alarm control unit 118 may cause an in-vehicle display device to display information indicating that the passengers will not continue to disembark, or transmit the information to the management server of the traffic management system 1A.

[0047] Fig. 5 is a diagram for explaining the operation status of shuttle bus B whose operation is managed by the operation management system 1A shown in Fig. 4. Fig. 6 is a flowchart for explaining the process of the operation management system 1A shown in Fig. 4.

[0048] As shown in Fig. 5, first, shuttle bus B stops at a rest point such as a service area. Driver D who gets on shuttle bus B turns off ignition switch 40. Alternatively, driver D operates an operation button for notifying the management server of operation management system 1A that the shuttle bus is about to start taking a break.

[0049] As shown in the flow chart of FIG. 6, the third measurement unit 115 of the CPU 11A receives an OFF signal of the ignition switch 40 and judges whether or not the current position of the shuttle bus B measured by the navigation system 30 coincides with the position of the rest point registered in advance (step S11). If a positive judgment is made in step S11, the third measurement unit 115 acquires the measurement value of the weight sensor 20 and stores it in the memory 12 (measurement before getting off in step S12). As described above, an operation button for notifying the start of a rest period may be provided in the vehicle-mounted device 10A, and when the third measurement unit 115 receives an ON signal of the operation button and the current position of the shuttle bus B measured by the navigation system 30 coincides with the position of the rest point registered in advance, the third measurement unit 115 may acquire the measurement value of the weight sensor 20 and store it in the memory 12. In addition, when the third measurement unit 115 receives an OFF signal of the ignition switch 40 or an ON signal of the operation button, the third measurement unit 115 may reset the measurement value of the weight sensor 20 to 0.

[0050] As shown in Fig. 5, after shuttle bus B arrives at the rest area, passengers get off shuttle bus B. Shuttle bus B waits at the rest area until all the passengers who got off get on. At this time, there is a possibility that passengers may remain outside shuttle bus B, i.e., passengers may be forgotten to board.

[0051] As shown in the flowchart of FIG. 6, after the passenger boards the shuttle bus B, the fourth measurement unit 116 of the CPU 11A judges whether or not an ON signal has been received from the ignition switch 40 (step S13). If a positive judgment is made in step S13, the fourth measurement unit 116 acquires the measurement value of the weight sensor 20 and stores it in the memory 12 (measurement after boarding in step S14). As described above, an operation button for notifying the end of the break may be provided in the vehicle-mounted device 10A, and when the fourth measurement unit 116 receives an ON signal from the operation button, the measurement value of the weight sensor 20 may be stored in the memory 12.

[0052] Next, the determination unit 117 of the CPU 11A calculates the difference (weight difference) between the measured value or zero value of the weight sensor 20 before disembarking stored in the memory 12 and the measured value of the weight sensor 20 after getting on stored in the memory 12, and determines whether the calculated weight difference is equal to or greater than a predetermined value ΔW2 (step S15). If the weight difference calculated in step S15 is equal to or greater than the predetermined value ΔW2 (YES in step S15), the alarm control unit 118 of the CPU 11A activates the alarm 14 (step S16). The alarm control unit 118 may transmit the alarm information to the management server of the fleet management system 1A.

[0053] If the weight difference calculated in step S15 is less than the predetermined value ΔW2 (NO in step S15), the process shown in the flowchart in Fig. 6 ends. Note that, if the weight difference calculated in step S15 is less than the predetermined value ΔW2, the warning control unit 118 may transmit information notifying that all passengers have boarded and information indicating the end of the break to the management server of the traffic management system 1A.

[0054] As described above, in the operation management system 1A according to this embodiment, if the difference between the measurement value of the weight sensor 20 before the passenger gets off the shuttle bus B stopped at the rest point or the zero value (third value) obtained by resetting the measurement value to zero and the measurement value (fourth value) of the weight sensor 20 after the passenger who got off at the rest point gets on the shuttle bus B is equal to or greater than the predetermined value ΔW2, the CPU 11A determines that the passenger continues to get off (forgot to board), and if the difference between the third value and the fourth value is less than the predetermined value ΔW2, it determines that the passenger has finished boarding. This makes it possible to confirm that all passengers have boarded the shuttle bus B after the passenger who got off at the rest point gets on.

[0055] The present invention has been described above based on the above embodiment, but the present invention is not limited to the above embodiment, and modifications may be made to the above embodiment without departing from the spirit of the present invention, and publicly known or well-known technologies may be combined as appropriate.

[0056] For example, in the traffic management system 1 of the above embodiment, a decision is made as to whether the child should disembark or continue riding based on the difference between the measurement value of the weight sensor 20 at the departure point and the measurement value of the weight sensor 20 at the return point. However, a decision as to whether the child should disembark or continue riding may be made based on the difference between the measurement value of the weight sensor 20 before the child boards shuttle bus B and the measurement value of the weight sensor 20 after the child disembarks from shuttle bus B.

[0057] In addition, in the traffic management system 1A of the above embodiment, the boarding and disembarking of the passengers is determined based on the difference between the measurement value of the weight sensor 20 before the passengers disembark at the rest point and the measurement value of the weight sensor 20 after the passengers board at the rest point. However, the boarding and disembarking of the passengers may be determined based on the measurement value of the weight sensor 20 before the vehicle arrives at the rest point and the measurement value of the weight sensor 20 before the vehicle departs from the rest point.

[0058] Furthermore, in the operation management systems 1 and 1A of the above embodiments, the occupants to be transported are kindergarten children or passengers, and the transport vehicle is a shuttle bus B for a kindergarten or nursery school, an express bus, an overnight bus, etc. However, the occupants to be transported are not limited to kindergarten children or passengers, and may be elderly people who require care, etc., and the transport vehicle may be a shuttle vehicle for an elderly care facility, etc. [Explanation of symbols]
