Description

This disclosure relates to a bus stop.

In order to smoothly manage the bus operation, it is necessary to accurately grasp the number of people waiting for the bus user at the bus stop (bus stop) in the bus operation management device that manages the bus operation. In addition, it is necessary to accurately grasp the traffic conditions on the road on which the bus travels.
For example, assume a situation where the number of people waiting at a certain bus stop (called bus stop α) is 0. At this time, if there are no passengers getting off at the bus stop α in the bus (referred to as bus A) heading for the bus stop α, the bus A does not need to stop at the bus stop α. In such a case, if the bus operation management device notifies the bus A that it is not necessary to stop at the bus stop α, the bus can continue to travel at a constant speed.
Also, assume a situation where traffic jams occur behind a certain bus (called bus B). In such a case, it is desirable that the bus operation management device grasps that the traffic jam is occurring behind the bus B. Further, it is desirable that the bus operation management device predicts that a delay will occur in the bus traveling behind the bus B and instructs the bus B to wait at the bus stop.

Patent Document 1 discloses a configuration in which a motion sensor is provided on a covered bench-type bus stop and the number of waiting bus users is counted by the motion sensor.

Patent No. 6337294

Embodiment 1.
*** Explanation of configuration ***
FIG. 1 shows a configuration example of the bus operation management system 50 according to the present embodiment. The bus operation management system 50 is a system that manages the operation of the bus 20. Bus 20 is a fixed-route bus.

Although only one bus stop 10 is shown in FIG. 1, a plurality of bus stops 10 are arranged along the route of the bus 20. It is assumed that each of the plurality of bus stops 10 has the configuration shown below.

The bus stop 10 has three or more sides. In the example of FIG. 1, the bus stop 10 has four sides. At the bus stop 10, the counting sensor 101 and the observation sensor 102 are arranged on different side surfaces.
Specifically, the counting sensor 101 is arranged on the side surface 11 in the direction in which the bus users 40 waiting for the bus 20 form a line. The counting sensor 101 counts the number of bus users 40.
The counting sensor 101 is, for example, a motion sensor, a visible camera, an infrared camera, or a millimeter wave radar. Further, the counting sensor 101 may be a composite sensor in which these are combined.

Further, the observation sensor 102 is arranged on the side surface 12 in the direction of the roadway on which the bus 20 travels. The observation sensor 102 observes the traffic condition of the roadway. The observation sensor 102 observes, for example, the number of vehicles traveling on the roadway, the average speed, and the like as the traffic conditions on the roadway. Further, the observation sensor 102 observes, for example, the arrival status of the bus 20 as the traffic condition of the roadway.
The observation sensor 102 is, for example, a visible camera, an infrared camera, a millimeter-wave radar, and a LiDAR (Light Detection and Ranking). Further, the observation sensor 102 may be a composite sensor in which these are combined.
When the observation sensor 102 is a millimeter wave radar or LiDAR, the observation sensor 102 can accurately detect the shape of the bus 20. Therefore, the observation sensor 102 can detect the arrival of the bus 20 by matching the shape of the bus 20 measured in advance with the detected shape.
When the observation sensor 102 is a millimeter wave radar or LiDAR, the observation sensor 102 emits a beam of the millimeter wave radar or LiDAR in a direction crossing the road as illustrated in the beam emission region 110 of FIG. Then, the observation sensor 102 receives the beam reflected by the bus 20 and observes the arrival status of the bus 20.
Further, if a reflective member having high reflection intensity is arranged on the bus 20, the detection accuracy of the bus 20 is improved. For example, as a reflective member, it is conceivable to arrange a reflective paint or a reflector that reflects a specific frequency used in a millimeter wave radar or LiDAR. The observation sensor 102 emits a beam of a millimeter wave radar or a LiDAR in a direction crossing the roadway as shown in FIG. Then, the observation sensor 102 receives the beam reflected by the reflective member of the bus 20 and observes the arrival status of the bus 20.

Further, the bus stop communication unit 103 wirelessly receives an instruction from the bus operation management device 30 to the bus 20. Then, the bus stop communication unit 103 wirelessly transmits the received instruction to the communication device mounted on the bus 20. For example, the bus stop communication unit 103 transmits an instruction to the communication device mounted on the bus 20 by DSRC (Dedicated Short Range Communications).
In FIG. 1, the communication device mounted on the bus 20 is not shown.

Further, the bus stop 10 may include a display display 15.
A message to the bus user 40 is displayed on the display display 15. Further, the instruction from the bus operation management device 30 to the bus 20 may be displayed on the display display 15.

The bus operation management device 30 is a server device that manages the operation of the bus 20.
The bus operation management device 30 manages the operation of the bus 20 by using the report data from the plurality of bus stops 10.
Further, the bus operation management device 30 generates an instruction to the bus 20 based on the report data from the plurality of bus stops 10, and the generated instruction is sent to at least one of the plurality of bus stops 10. Send.

*** Explanation of operation ***
Next, an operation example of the bus stop 10 and the bus operation management device 30 according to the present embodiment will be described.

FIG. 5 shows an example of counting processing by the counting sensor 101 of the bus stop 10.

The counting sensor 101 determines whether or not the counting timing of the periodically arriving waiting number has arrived (step S501).
The cycle of the counting timing can be arbitrarily determined by the administrator of the bus operation management system 50. For example, it is conceivable to set the counting timing cycle to 1 minute.

When the counting timing has arrived (YES in step S501), the counting sensor 101 counts the number of people waiting for the bus user 40 at the bus stop 10 (step S502).
The counting sensor 101 analyzes, for example, an image taken by a visible camera or an infrared camera and counts the number of people waiting.
The counting sensor 101 may accurately measure the number of people waiting, or may determine only the presence or absence of the bus user 40 (whether the number of bus users 40 is 0 or 1 or more). Further, the counting sensor 101 may determine only whether the number of bus users 40 is small or large when there are bus users 40. In addition to accurately determining the number of people waiting, the "counting" includes determination of the presence or absence of such bus users 40 and determination of whether the number of bus users 40 is small or large.

Next, the counting sensor 101 outputs the counting result to the control unit 104 (step S503).

FIG. 9 shows an example of the counting result output from the counting sensor 101 to the control unit 104.
The counting result includes the bus stop ID (Identifier) of the bus stop of the transmission source of the counting result, the time when the number of waiting people is measured, and the counted number of waiting people.
Bus stop ID: AA14 is an identifier of the bus stop 10 shown in FIG.
As mentioned above, the "waiting number" column does not have to indicate the exact number of people, only the presence or absence of the bus user 40, and only the presence or absence of the bus user 40, whether the number of bus users 40 is small or large. You may.

FIG. 6 shows an example of observation processing by the observation sensor 102 of the bus stop 10.

The observation sensor 102 determines whether or not the observation timing of the periodic traffic condition has arrived (step S601). The cycle of the observation timing can be arbitrarily determined by the administrator of the bus operation management system 50. For example, it is conceivable that the observation timing cycle is 10 seconds.

When the observation timing has arrived (YES in step S601), the observation sensor 102 observes the traffic condition on the roadway (step S602).
The observation sensor 102, for example, analyzes a moving image taken by a visible camera or an infrared camera to measure the number of vehicles passing in front of the bus stop 10 and the average speed. The observation sensor 102 photographs the roadway with a visible camera or an infrared camera for, for example, for 5 seconds, and measures the number of vehicles appearing in the moving image for 5 seconds and the average speed of the vehicles.
The observation sensor 102 also determines whether or not the bus 20 has arrived in the observation of the traffic condition in step S602.

When the arrival of the bus 20 is detected in the observation of the traffic condition in step S602 (YES in step S603), the observation sensor 102 outputs the observation result including the bus arrival notification notifying the arrival of the bus to the control unit 104. In the following, the observation result including the bus arrival notification is referred to as the observation result (bus arrival notification).

On the other hand, when the arrival of the bus 20 is not detected in the observation of the traffic condition in step S602 (NO in step S603), the normal observation result not including the bus arrival notification is output to the control unit 104. In the following, the observation result that does not include the bus arrival notification is referred to as the observation result (normal notification).

FIG. 10 shows an example of an observation result (normal notification) output from the observation sensor 102 to the control unit 104.
The observation result (normal notification) includes the bus stop ID of the bus stop of the source of the observation result (normal notification), the time when the traffic condition was observed, and the observed traffic condition. In the observation result (normal notification), the number of vehicles and the average speed measured by the observation sensor 102 are shown as the traffic conditions.

The observation result (bus arrival notification) includes information on the bus 20 whose arrival has been detected, in addition to the elements included in the observation result (normal notification) of FIG. In the example of FIG. 11, the bus ID and the system number (route system) of the bus 20 whose arrival is detected are included.
In the present embodiment, the observation sensor 102 can acquire the bus ID of the bus 20, but if the observation sensor 102 cannot acquire the bus ID, the bus ID may not be available.
Further, the observation sensor 102 analyzes, for example, an image taken by the bus 20 by a visible camera or an infrared camera, and recognizes the system number displayed on the bus 20.

FIG. 7 shows an example of bus stop communication processing by the bus stop communication unit 103 of the bus stop 10.

When the bus stop communication unit 103 receives an instruction from the bus operation management device 30 (YES in step S701), the bus stop communication unit 103 outputs the instruction to the control unit 104 (step S702).

Further, when the instruction is input from the control unit 104 (YES in step S703), the bus stop communication unit 103 transmits the instruction to the communication device of the bus 20 (step S704).

Further, when the report data is input from the control unit 104 (YES in step S705), the bus stop communication unit 103 transmits the report data to the bus operation management device 30 (step S706).

FIG. 8 shows an example of control processing by the control unit 104 of the bus stop 10.

When the processor 106 of the control unit 104 inputs an instruction of the bus operation management device 30 from the bus stop communication unit 103 via the communication unit interface 108 (YES in step S801), the processor 106 stores the instruction in the memory 107 and stores the instruction in the memory 107. Stores the instruction (step S802).

Further, when the counting result is input from the counting sensor 101 via the sensor interface 105 (YES in step S803), the processor 106 stores the counting result in the memory 107, and the memory 107 stores the counting result (step S804). ).

Further, when the observation result is input from the observation sensor 102 via the sensor interface 105 (YES in step S805), the processor 106 stores the observation result in the memory 107, and the memory 107 stores the observation result (step S806). ).

Further, the processor 106 determines whether or not the observation result input in step S805 is the observation result (bus detection notification) and the instruction of the bus operation management device 30 is stored in the memory 107 (step S807). ).
When the observation result input in step S805 is the observation result (bus detection notification) and the instruction of the bus operation management device 30 is stored in the memory 107 (YES in step S807), the instruction is given to the bus stop communication unit 103. Is output to (step S808).

Further, the processor 106 determines whether or not the reporting timing to the periodically arriving bus operation management device 30 has arrived (step S809).
The cycle of the reporting timing can be arbitrarily determined by the administrator of the bus operation management system 50. For example, it is conceivable that the reporting timing cycle is 5 minutes.

When the report timing has arrived (YES in step S809), the processor 106 generates report data (step S810).
Then, the processor 106 outputs the generated report data to the bus stop communication unit 103 via the communication unit interface 108 (step S811).

FIG. 12 shows an example of instructions of the bus operation management device 30.
The instruction of the bus operation management device 30 includes the bus stop ID of the bus stop 10 which is the destination of the instruction, the generation time of the instruction, and the content of the instruction.
The content of the instruction is an instruction regarding the operation of the bus 20. In the example of FIG. 12, the bus operation management device 30 instructs the bus 20 to wait for one minute because the subsequent bus has a delay in the system 21.
Further, for example, when the number of people waiting at the bus stop 10 to which the bus 20 heads next is 0, the bus operation management device 30 stops at the bus stop 10 if there are no passengers getting off at the bus stop 10. You may generate an instruction to continue running without.

FIG. 13 shows an example of report data generated by the processor 106 of the control unit 104.
The report data includes the bus stop ID of the bus stop from which the report data is transmitted, the generation time of the report data, the count result of the count sensor 101, and the observation result of the observation sensor 102.
In the example of FIG. 13, the counting result of FIG. 9 and the observation result of FIG. 11 (bus arrival notification) are included.

FIG. 14 shows an operation management communication process by the operation management communication unit 301 of the bus operation management device 30 according to the present embodiment.

When the operation management communication unit 301 receives the report data from the bus stop 10 (YES in step S1401), the operation management communication unit 301 outputs the report data to the operation management unit 302 (step S1402).

Further, when the operation management communication unit 301 inputs an instruction to any of the bus stops 10 from the operation management unit 302 (YES in step S1403), the operation management communication unit 301 transmits the instruction to the corresponding bus stop 10 (step S1404).

FIG. 15 shows an example of operation management processing by the operation management unit 302 of the bus operation management device 30 according to the present embodiment.

The processor 304 of the operation management unit 302 determines whether or not the report data has been input from the operation management communication unit 301 via the communication unit interface 303 (step S1501.
When the report data is input from the operation management communication unit 301 (YES in step S1501), the processor 304 stores the report data in the memory 305, and the memory 305 stores the report data (step S1502).

Further, the processor 304 determines whether or not the instruction generation timing that arrives periodically has arrived (step S1503).
The cycle of the instruction generation timing can be arbitrarily determined by the administrator of the bus operation management system 50. For example, it is conceivable that the cycle of the instruction generation timing is 5 minutes.

When the instruction generation timing arrives (YES in step S1503), the processor 304 analyzes the report data from the plurality of bus stops 10 stored in the memory 305 (step S1504).
Any analysis method may be used by the processor 304.
For example, in the report data from a plurality of bus stops 10 existing in a certain section of the bus 20 route, the arrival time of the bus shown in the observation result (bus arrival notification) is behind schedule, and the number of vehicles is the threshold value. Less than, and the average speed is less than the threshold. In this case, the processor 304 estimates that congestion has occurred in the section.
Further, the processor 304 may acquire traffic information on the route of the bus 20 from an external information source other than the bus stop 10 by communication, and perform analysis by combining the report data and the traffic information from the external information source.

Next, the processor 304 generates an instruction for each bus stop 10 based on the analysis result in step S1504 (step S1505).
For example, when it is estimated in step S1504 that a traffic jam is occurring in a specific section as described above, the processor 304 causes a traffic jam to the bus stop 10 in front of the traffic jam section, for example, in front of the bus stop 10. Since there is a possibility that the vehicle traveling ahead may suddenly decelerate or stop suddenly, an instruction to instruct the bus 20 to increase the inter-vehicle distance is generated. Further, the processor 304 has a traffic jam at the rear of the bus stop 10 at the end of the congested section, for example, and there is a possibility that a delay may occur at the rear bus. Generate an instruction to stop at bus stop 10.
Further, to the bus stop 10 having no waiting number of people, an instruction is generated to instruct the bus 20 heading for the bus stop 10 to continue traveling without stopping at the bus stop 10.

After that, the processor 304 outputs the generated instruction to the operation management communication unit 301 via the communication unit interface 303 (step S1506).

In the above, an example in which both the counting sensor 101 and the observation sensor 102 are arranged on the bus stop 10 has been described, but only one of the counting sensor 101 and the observation sensor 102 is arranged on the bus stop 10. May be good.
In this case, the report data transmitted from the bus stop 10 to the bus operation management device 30 includes only one of the counting result of the counting sensor 101 and the observation result of the observation sensor 102.

*** Explanation of the effect of the embodiment ***
As described above, in the present embodiment, at least one of the counting result of the number of waiting people obtained at the bus stop 10 and the observation result of the traffic condition of the roadway is notified to the bus operation management device 30.
Therefore, the bus operation management device 30 can effectively manage the operation of the bus based on at least one of the number of people waiting at the bus stop 10 and the traffic condition around the bus stop 10.

Further, the bus stop 10 according to the present embodiment is a columnar bus stop. Therefore, even if the installation space is not sufficient, the bus stop 10 can be installed so that the number of waiting people can be counted and the traffic condition can be observed. That is, even when the covered bench type bus stop disclosed in Patent Document 1 cannot be arranged due to the installation space, the bus stop 10 according to the present embodiment can be installed. Therefore, it is possible to count the number of people waiting and observe the traffic condition at all the bus stops 10 of the bus route without omission.
Further, if the columnar bus stop 10 is used, the installation cost can be suppressed lower than that of the covered bench type bus stop of Patent Document 1.

Embodiment 2.

The bus stop 71 is an adjacent bus stop in the direction of the departure point of the bus 20. The bus stop 72 is an adjacent bus stop in the direction of the destination of the bus 20. The bus stop 71 and the bus stop 72 correspond to the examples of other bus stops.
The bus stop 71 and the bus stop 72 are collectively referred to as the bus stop 70. Further, the relay device 61 and the relay device 62 are collectively referred to as a relay device 60.

In FIG. 17, steps S701 to S706 are the same as those shown in FIG. 7, and therefore the description thereof will be omitted.
If the bus stop communication unit 103 does not input the report data from the processor 304 in step S705, or after the bus stop communication unit 103 transmits the report data to the bus operation management device 30 in step S706, the process proceeds to step S707 of FIG. ..

When the bus stop communication unit 103 receives the failure notification from the adjacent bus stop 70 from the relay device 60 (YES in step S707), the bus stop communication unit 103 outputs the failure notification to the control unit 104 (step S708).
Step S707 is YES when the failure notification is received from at least one of the bus stop 71 and the bus stop 72.
Although the details will be described later, the failure notification is a notification for notifying the failure when the bus stop 70 discovers a failure in the bus operation management device 30 or a failure in the communication line with the bus operation management device 30. The failure notification includes the observation result at the bus stop 70 from which the failure notification is transmitted.

Further, when the bus stop communication unit 103 receives the ACK from the adjacent bus stop 70 (YES in step S709), the bus stop communication unit 103 outputs the ACK to the control unit 104 (step S710).
Step S709 is YES when ACK is received from at least one of the bus stop 71 and the bus stop 72.
Although the details will be described later, ACK is a notification for notifying that the bus stop 70 has normally received the failure notification. The ACK includes the observation result at the bus stop 70, which is the source of the ACK.

Further, when the failure notification is input from the control unit 104 (YES in step S711), the bus stop communication unit 103 transmits the failure notification to the bus stop 70 (step S712).
This failure notification is a notification for notifying the bus stop 70 of a failure when the control unit 104 finds a failure in the bus operation management device 30 or a failure in the communication line with the bus operation management device 30. This failure notification includes the observation result by the observation sensor 102.

Further, when the bus stop communication unit 103 inputs the ACK from the control unit 104 (YES in step S713), the bus stop communication unit 103 transmits the ACK to the bus stop 70 (step S714).
The bus stop 70 in this case is the bus stop 70 of the transmission source of the failure notification received in step S707.
Further, this ACK is a notification for notifying that the control unit 104 has normally received the failure notification. This ACK includes the observation result by the observation sensor 102.

After the above steps S707 to S714, the process returns to step S701 in FIG.

19 and 20 show an example of control processing by the control unit 104 of the bus stop 10 according to the present embodiment.

In FIG. 17, since steps S801 to S811 are the same as those shown in FIG. 8, the description thereof will be omitted.
In step S812, the processor 106 of the control unit 104 determines whether or not the instruction of the bus operation management device 30 has been input even after the input timing of the instruction of the bus operation management device 30 has passed.
The input timing of the instruction can be determined from the instruction generation timing (step S1503 in FIG. 15) in the bus operation management device 30.
If the instruction of the bus operation management device 30 is not input even after the input timing of the instruction (YES in step S812), the process proceeds to step S812 of FIG.

In step S813, the processor 106 determines whether or not the failure notification from the bus stops 70 on both sides is input from the bus stop communication unit 103.

When the failure notification from the adjacent bus stops 70 is not input from the bus stop communication unit 103 (NO in step S813), the processor 106 sends the failure notification from either bus stop 70 to the bus stop communication unit. It is determined whether or not the input is from 103 (step S814).

When the failure notification from one of the bus stops 70 is input (YES in step S814), the processor 106 generates an ACK to the bus stop 70 from which the failure notification is transmitted, and the other bus stop 70. The failure notification is generated, and the generated ACK and the failure notification are output to the bus stop communication unit 103 (step S815).

On the other hand, when the failure notification from any of the bus stops 70 is not input (NO in step S814), the processor 106 generates a failure notification to the bus stops 70 on both sides, and the generated failure notification is bus-stopped. Output to the communication unit 103 (step S816).

After step S815 or step S816, the processor 106 inputs an ACK from the bus stop communication unit 103 (step S817).
After step S815 is performed, the processor 106 inputs an ACK from the bus stop 70 to which the failure notification is transmitted. On the other hand, after step S816 is performed, the processor 106 inputs an ACK from the bus stops 70 on both sides (step S817).

On the other hand, when the failure notification is input from the bus stops 70 on both sides in the determination in step S813, the processor 106 generates an ACK to the bus stops 70 on both sides, and the generated ACK is sent to the bus stop communication unit 103. Output (step S818).

Here, an example of failure notification and ACK will be described.
FIG. 21 shows an example of a failure notification.
FIG. 22 shows an example of ACK.

The failure notification includes the bus stop ID of the bus stop of the transmission source of the failure notification, the bus stop ID of the bus stop of the transmission destination, and the observation result at the bus stop of the transmission source of the failure notification.
In the example of FIG. 21, the bus stop ID of the transmission source bus stop is AA14, and the bus stop IDs of the transmission destination bus stop are AA13 and AA15. Further, in the example of FIG. 21, the observation result (bus arrival notification) is notified.
The observation result (bus arrival notification) included in the failure notification corresponds to the other bus stop observation result information.

ACK includes the bus stop ID of the bus stop of the source of ACK, the bus stop ID of the bus stop of the destination of ACK (the source of the failure notification), and the observation result at the bus stop of the source of ACK. Is done.
In the example of FIG. 22, the bus stop ID of the transmission source bus stop is AA14, and the bus stop ID of the transmission destination bus stop is AA13. Further, in the example of FIG. 22, the observation result (bus arrival notification) is notified.
The observation result (bus arrival notification) included in the ACK transmitted from the bus stop 70 to the bus stop 10 corresponds to other bus stop observation result information.

After step S817 or step S818, the processor 106 analyzes the counting result of the counting sensor 101, the observation result of the observation sensor 102, and the observation result from the bus stop 70 (step S819).
Any analysis method may be used by the processor 106.
For example, the arrival time of the bus shown in the failure notification or the ACK observation result (bus arrival notification) from the bus stop 70 (that is, the bus stop 71) near the departure point of the bus 20 among the bus stops 70 is delayed from the schedule. Also, it is assumed that the number of vehicles is less than the threshold and the average speed is less than the threshold. Further, it is assumed that the arrival time of the bus indicated by the latest observation result (bus arrival notification) by the observation sensor 102 is later than planned, the number of vehicles is less than the threshold value, and the average speed is less than the threshold value. In this case, the processor 106 estimates that congestion has occurred in the section from the bus stop 71 to the bus stop 10.
Further, for example, the arrival time of the bus indicated in the failure notification or the ACK observation result (bus arrival notification) from the bus stop 70 (that is, the bus stop 72) near the destination of the bus 20 among the bus stops 70 is more than planned. It is assumed that there is a delay, the number of vehicles is below the threshold, and the average speed is below the threshold. Further, it is assumed that the arrival time of the bus indicated by the latest observation result (bus arrival notification) by the observation sensor 102 is later than planned, the number of vehicles is less than the threshold value, and the average speed is less than the threshold value. In this case, the processor 106 estimates that congestion has occurred in the section from the bus stop 10 to the bus stop 72.
Further, the processor 106 acquires the traffic information on the route of the bus 20 from an external information source by communication, and combines the observation result of the bus stop 71 and / or the observation result of the bus stop 72 with the traffic information from the external information source. Analysis may be performed.

Next, the processor 106 generates an instruction to the bus 20 based on the analysis result in step S819 (step S820).
For example, if it is estimated in step S819 that traffic congestion occurs in the section from bus stop 10 to bus stop 72 as described above, the processor 106, for example, has traffic congestion in front and travels ahead. Since the vehicle may suddenly decelerate or stop suddenly, an instruction to instruct the bus 20 to increase the inter-vehicle distance is generated.
Further, when it is estimated that the traffic jam occurs in the section from the bus stop 71 to the bus stop 10, the processor 106 may have a traffic jam in the rear, for example, and a delay may occur in the bus 20 in the rear. Therefore, an instruction is generated to instruct the bus 20 to stop at the bus stop 10 for time adjustment.
When the number of people waiting for the bus stop 10 is 0, the processor 106 generates, for example, an instruction instructing the bus 20 to continue traveling without decelerating at the bus stop 10.

After that, the processor 106 outputs the generated instruction to the bus stop communication unit 103 via the communication unit interface 108 (step S821).

After the above steps S813 to S821, the process returns to step S801 of FIG.
