DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toll collection system such as a non-stop toll collection system installed on a toll road, and a vehicle behavior management method.

[0002]

2. Description of the Related Art In recent years, non-stop toll collection systems, that is, ETC systems, have been introduced on toll roads such as expressways.

[0003] As a toll collection system conventionally introduced on toll roads, a magnetic card type system (hereinafter referred to as a toll ticket system) is known.

There are two types of toll ticket systems: a driver of a vehicle receives a toll ticket at the entrance of a toll road, presents a toll ticket at an exit, and pays a toll according to the usage distance. Alternatively, there is a uniform fee system that pays a fixed fee at the exit.

[0005] In parallel with such existing systems, ET
In order to introduce the C system sequentially on toll roads, E
It is necessary to make the TC system a configuration suitable for each of the distance-to-distance system and the flat-rate system.
Various configurations such as a one-antenna system and a two-antenna system have been considered.

[0006] One antenna system is provided in each lane at the exit of a toll road with a distance.

In the case of this one-antenna system, as shown in FIG. 5, when the vehicle 20 travels in the vehicle traffic direction (the direction of the arrow) and enters the position of the first sensor 46, the vehicle 20 The detected radio wave is emitted from the antenna 12, and communication between the vehicle-mounted device 6 of the vehicle 20 and the antenna 12 is started. If the communication is normally completed before the vehicle 20 reaches the position of the second sensor 50, the vehicle 2
0 is treated as an ETC vehicle, and the start controller 56 is opened.

An abnormal ETC vehicle occurs when communication between the antenna 12 and the vehicle-mounted device 6 of the vehicle 20 occurs, and a non-ETC vehicle occurs when communication is not completed before the vehicle 20 reaches the position of the second sensor 50. Each of them is treated as a car, and the start controller 56 is closed. At this time, the communication result of the antenna 12 is displayed on the roadside display 54, and the third sensor 5
8 when the vehicle 20 enters the position 8. The communication result is a host computer (not shown) which is a higher-level device.
To be notified.

[0009] The two-antenna system is provided at the entrance of a toll road of a distance-based system or at the entrance or exit of a toll system.

In the case of the two-antenna system, as shown in FIG. 3, the vehicle 20 travels in the vehicle traffic direction (the direction of the arrow), and when it reaches the position of the first sensor 38, the first sensor 38 detects Then, radio waves are emitted from the first antenna 8,
Communication is started between the vehicle-mounted device 6 of the vehicle 20 and the first antenna 8.

If the communication is completed normally before the vehicle 20 reaches the position of the second sensor 26, the vehicle 20 is treated as an ETC vehicle, and the start controller 35 is opened. If an abnormality occurs in communication with the first antenna 8, the vehicle is treated as an abnormal ETC vehicle. If communication is not completed before the vehicle 20 enters the position of the sensor 2, the vehicle is treated as a non-ETC vehicle. 35 is closed. The communication result of the first antenna 8 is displayed on the roadside display 28 and is erased when the vehicle enters the position of the third sensor 32.

When the vehicle 20 reaches the position of the fourth sensor 36, a radio wave is emitted from the second antenna 10,
Communication is performed between the vehicle-mounted device 6 of the vehicle 20 and the second antenna 10. When the toll collection process for one vehicle is completed in this way, the result of the communication is notified to a host computer (not shown), which is a higher-level device.

There is a problem that the display of the container is shifted.

Further, in the two-antenna system, if an erroneous detection occurs in each of the sensors, the result of processing by the two antennas is for a different vehicle.
When a phenomenon occurs in which the management data becomes inconsistent, and this erroneous processing result is notified to the higher-level device, the higher-level device also becomes inconsistent with the management data,
There is a problem that it interferes with the operation of the system.

The present invention has been made in order to solve such a problem, and an object of the present invention is to provide a toll collection system and a vehicle behavior management method which can make a staff member aware of erroneous detection of a sensor.

By controlling the first antenna 8, radio waves are radiated from the first antenna 8, and the vehicle-mounted device 6 of the vehicle 20 and the first antenna 8
Communication starts with.

If the communication is normally completed before the traveling vehicle 20 reaches the position of the second sensor 26, the vehicle 20 is treated as an ETC vehicle, and the start controller 35 is opened.

On the other hand, when an abnormality occurs in the communication by the first antenna 8, the entrance lane controller 24 controls the vehicle 20.
Are treated as abnormal ETC vehicles. If the communication is not completed before the vehicle 20 reaches the position of the second sensor 26, the vehicle is treated as a non-ETC vehicle, and the start controller 35 is closed.

After the communication result of the first antenna 8 is displayed on the roadside display 28, the vehicle 20
The display on the roadside display 28 is erased by reaching the position 2 and being detected by the third sensor 32.

The vehicle 2 that has passed the position of the third sensor 32
When 0 reaches the position of the fourth sensor 36, the fourth sensor 36 detects this and notifies the entrance lane control device 24, so that the second antenna 1 is controlled by the entrance lane control device 24.
Radio waves are radiated from 0, communication is performed between the vehicle-mounted device 6 of the vehicle 20 and the second antenna 10, and the entrance processing ends. In this way, the entrance processing for one vehicle 20 is performed, and the result of the entrance processing is transferred to the host computer 60 (tollgate server), which is the host device.

Next, the exit process of the toll collection system will be described.

At the exit of the toll road, when the vehicle 20 enters the exit lane (lane) of the toll gate, the first sensor 46 detects this and notifies the exit lane controller 52.

Then, the exit lane control device 52 controls the antenna 12 to emit a radio wave from the antenna 12, and communication between the vehicle-mounted device and the antenna 12 is started. If the communication is normally completed before the vehicle 20 reaches the position of the second sensor 50, the vehicle 20 is treated as an ETC vehicle by the exit lane control device 52, and the start controller 56 is opened. You.

If an abnormality occurs during communication between the antenna 12 and the vehicle-mounted device 6 of the vehicle 20, the vehicle 20 is treated as an abnormal ETC vehicle by the exit lane control device 52. Also, when the communication is not completed before the vehicle 20 reaches the position of the second sensor 2, the vehicle 20 is treated as a non-ETC vehicle by the exit lane control device 52. When the vehicle 20 is a non-ETC vehicle or an abnormal ETC vehicle, the start control unit 56 is closed and the vehicle is ready for collection, and the charge collection process is performed by transferring the IC card 16 at the collection booth 48 installed in the same lane. Alternatively, a toll collection process using a conventional toll ticket is performed.

The result of the communication processing by the antenna 12 is displayed on the roadside display 54, and is deleted when the vehicle 20 reaches the position of the third sensor 58.

The result of the above processing is transmitted from the exit lane controller 52 to the host computer 60 which is a higher-level device.
(Tollgate server).

When the non-ETC vehicle and the abnormal ETC vehicle have completed the toll collection process in the collection booth 48, the exit lane control device 52 opens the transmission controller 56 to urge the vehicle 20 to start (pass). .

Next, the vehicle behavior management operation of each lane control device at the entrance and exit in the toll collection system will be described. FIG. 9 is a diagram showing a vehicle behavior management queue of the entrance lane control device 24. The vehicle behavior management queue is a table indicating a vehicle situation in a lane set in a memory in the entrance lane control device 24 or the exit lane control device 52.

For example, the vehicle 20 that has entered the entrance lane
When the vehicle 20 is detected by the first sensor 38, the entrance lane control device 24
The vehicle pointer is registered in the vehicle behavior management queue as vehicle data, and the latest pointer is changed to the vehicle data.

First to fourth sensors 38, 26, 32, 36
The vehicle data is provided with a behavior data area in order to manage the vehicle behavior by detecting the vehicle entry / vehicle passage at the vehicle. From this behavior data, it is possible to grasp where the vehicle 20 is located in the lane. Also,
The vehicle behavior management queue is also provided with an area for holding communication results (communication contents) of the first antenna 8 and the second antenna 10. Vehicle 20 is the fourth sensor 3
When the vehicle 20 passes (exits) the position of the vehicle 20
Is removed from the vehicle behavior management queue, the entrance lane control device 24 updates the oldest pointer in the vehicle behavior management queue.

In this example, vehicles enter the lane in the order of vehicle "A", vehicle "B", and vehicle "C", and from the positions of the oldest pointer and the latest pointer, all three vehicles still exist in the lane. You can see that

Thereafter, when the vehicle "A" passes the position of the fourth sensor 36, the oldest pointer is updated to the position of the vehicle "B".

When the next vehicle enters the lane after the vehicle "C" and reaches the position of the first sensor 38, the vehicle enters the vehicle behavior management queue next to the vehicle "C". The vehicle is registered and the latest pointer is updated to the vehicle.

Here, the operation process of the vehicle behavior management queue will be described with reference to FIG. FIG. 10 is a flowchart showing the operation processing of the vehicle behavior management queue by the entrance lane control device 24.

As shown in the figure, when the entry of the vehicle 20 is detected by the first sensor 38 (Yes in S101).
s), the entrance lane control device 24 registers the vehicle data for the vehicle 20 in the vehicle behavior management queue (S102), updates the latest pointer (S103), and turns on the corresponding behavior bit (S104).

Subsequently, the vehicle 20 is detected by the second sensor 26.
Is detected (Yes in S105), the entrance lane control device 24 writes the communication content of the first antenna 8 in the vehicle behavior management queue (S106), and turns on the corresponding behavior bit (S106). S104). Further, when the passage (exit) of the vehicle 20 is detected by the fourth sensor 36 (Yes in S107), the entrance lane control device 24 sets the second
Is written into the vehicle behavior management queue (S108), the oldest pointer is updated to remove the vehicle data from the vehicle behavior management queue (S109), and the corresponding behavior bit is turned on (S104). .

Thus, the entrance lane control device 24
Stores the detection result (behavior bit) of each sensor and the communication content of each antenna in the vehicle behavior management queue in association with each other.

Recently, vehicles having various shapes have been put on the market, and each sensor erroneously detects a vehicle entering the lane (an erroneous detection of one vehicle such as a towing vehicle or a trailer as two vehicles, or There is a possibility that two vehicles running close to each other will be erroneously detected as one).

Several patterns in the case where the sensor makes an erroneous detection will be described below with reference to FIGS.

In the entrance gate device 2 to which the two-antenna system is applied, there are four sensors, from the first sensor 38 to the fourth sensor 36, each of which may be erroneously detected. Is not a problem because it does not relate to the presence or absence of the vehicle itself. However, erroneous detection by the first sensor 38 and the fourth sensor 36 causes a problem because the latest pointer and the oldest pointer in the vehicle behavior management queue are updated.

For example, as shown in FIG. 11, the first sensor 38 accurately identifies the four vehicles “A”, “B”, “C”, and “D” individually, but the fourth sensor 36 May erroneously detect the first vehicle “A” and the second vehicle “B” as one vehicle “X” (first pattern).

In the case of the first pattern, the first antenna 8 performs communication for two devices, but the second antenna 10
In this case, since only communication for one vehicle is performed, the second vehicle remains in front of the fourth sensor 36 in the vehicle behavior management queue.

In the first pattern, the entrance lane control device 24 treats the vehicle “A” and the vehicle “X” as one vehicle, and notifies the host computer 60 of the communication result.

The data of the vehicle “B” remains in the vehicle behavior management queue. When the next third vehicle passes, the vehicle “B” and the vehicle “Y” are regarded as one vehicle (abnormal ETC vehicle). This causes a shift in the correspondence between vehicle data in the vehicle behavior management queue. This shift needs to be corrected because a problem occurs in system operation.

Therefore, the entrance lane control device 24 applies the first antenna 8 and the second antenna to the vehicle determined to be the abnormal ETC vehicle based on the communication results of the first antenna 8 and the second antenna 10. It is checked whether the vehicle is another vehicle from the "vehicle device information" received in step 10 respectively. The “vehicle-mounted device information” includes, for example, vehicle-specific information such as vehicle license plate information and external shape data in addition to the vehicle-mounted device ID.

As a result of this check, if the vehicle is a different vehicle, there is a possibility that the correspondence between the vehicle data in the vehicle behavior management queue may be "misaligned".
Performs a check with vehicle data before and after the vehicle behavior management queue to check whether there is an identical vehicle.

In the example of the vehicle behavior management queue shown in FIG.
For example, when the vehicle “B” becomes an abnormal ETC vehicle, the entrance lane control device 24 checks “the first antenna communication content” and “the second antenna communication content” of the vehicle “A” and the vehicle “C”, Check for any deviation.

If the first pattern in FIG. 11 is erroneously detected, the abnormal ETC is detected by a combination of the vehicle “B” and the vehicle “Y”.
Since the vehicle is determined to be a car, the preceding and following vehicles are checked, but no corresponding vehicle is found.

Next, upon entry of the fourth vehicle, the entrance lane control device 24 causes the vehicle “C” and the vehicle “Z” to detect the abnormality E
It is determined as a TC vehicle.

[0093] In this case as well, when the vehicle is checked with the preceding and following vehicles,
It turns out that the vehicle "C" and the vehicle "Y" are the same vehicle. Since it is already known that the vehicle “A” and the vehicle “X” are the same vehicle, only the vehicle “B” remains as a result of the communication by the first antenna 8.

Therefore, the entrance lane control device 24 sequentially corrects the combination and replaces the “first antenna communication content” and “second antenna communication content” of each vehicle data in the vehicle behavior management queue. , And notifies the host computer 60 of the correction of the communication result.

The entrance lane control device 24 monitors the time, and if there is a vehicle in the lane even after a certain period of time, similarly to the preceding and following vehicles, based on the “vehicle information on the vehicle”, the vehicle is checked. Is performed to check whether or not the vehicle data is shifted.

In the case of the first pattern shown in FIG. 11, first,
Since the vehicle “B” remains in the lane, no corresponding vehicle is found even if the preceding and following vehicles are checked. Next, vehicle "C"
Remains in the lane, and checking the preceding and following vehicles reveals that the vehicle "Y" communicated by the second antenna 10 of the preceding vehicle is the same vehicle as the vehicle "B".

[0097] Thus, although a deviation occurs between the vehicle "B" and the vehicle "Y", since it has been determined that the vehicle "A" and the vehicle "X" are the same vehicle, the first vehicle is eventually ended. As a result of the communication using the antenna 8, only the vehicle “B” remains,
The entrance lane control device 24 sets the second vehicle to abnormal ETC
The third vehicle is changed to a combination of the vehicle “C” and the vehicle “Y”, and “first antenna communication content” and “second antenna communication content” of each vehicle data in the vehicle behavior management queue are changed. Are exchanged, and the correction of the communication result is notified to the host computer 60. In this way, the deviation of the correspondence can be corrected.

As shown in FIG. 12, when two vehicles are erroneously detected as one vehicle by the first sensor 38, and the fourth sensor 36 normally identifies each vehicle individually (the second vehicle). (Pattern 2), the first antenna 8 performs only communication for two vehicles, and the second antenna 10 performs communication for two vehicles, and then a third vehicle appears immediately.

This cannot be a vehicle running, but cannot be deleted because the vehicle "Z" actually exists.

In this case, when checking the preceding and following vehicles by the method described with reference to FIG. 11, it is determined that the vehicle "A" and the vehicle "X" and the vehicle "B" and the vehicle "Z" are the same vehicle. As a result, the vehicle "Y" remains as a result of the communication by the second antenna 10. Therefore, the entrance lane control device 24
The first vehicle is regarded as an abnormal ETC vehicle, and the combinations of the first and third vehicles are sequentially corrected, and the “first antenna communication contents” and “second antenna communication contents” of each vehicle data in the vehicle behavior management queue are changed. The antenna communication contents are exchanged, and the host computer 60 is notified of the correction of the communication result.

As shown in FIG. 13, the first sensor 38 erroneously detects one vehicle as two vehicles, and the fourth sensor 36
When the individual is properly identified (third pattern), the first antenna 8 performs communication for two units, but the second unit is not completed due to a ghost car due to vehicle separation, and the communication is not completed.
Become a car. In the vehicle behavior management queue, the first antenna 8 determines that the vehicle is a non-ETC vehicle, and one vehicle moves to the second antenna 10.
Will exist before the.

In the third pattern, since the vehicle "B" is a non-ETC vehicle, the start controller 35 is closed. At this time, a human operation is required. Therefore, the vehicle data is deleted from the vehicle behavior management queue by a data correction operation (manual input) from the operation panel 29, thereby correcting the deviation of the vehicle data in the vehicle behavior management queue. I do.

If the vehicle data is not deleted at this time, the vehicle "A" is identified by checking the preceding and following vehicles by the method described for the first pattern in FIG. The vehicle “X”, the vehicle “C” and the vehicle “Y” are determined to be the same vehicle, and the communication result by the first antenna 8
Vehicle "B" (non-ETC vehicle) remains. Therefore,
The entrance lane control device 24 sequentially corrects the combination and replaces the “first antenna communication content” and the second antenna communication content of each vehicle data in the vehicle behavior management queue. Although the first and second vehicle data can be corrected, a ghost car called vehicle "B" is generated. Therefore, the function of deleting the vehicle data from the vehicle behavior management queue retroactively to the entry lane has been provided. It is provided on the operation panel 29 of the control device 24.

As shown in FIG. 14, when the first sensor 38 is correctly identified, but the fourth sensor 36 erroneously detects one vehicle as two vehicles (fourth pattern), This fourth pattern is the second pattern (FIG. 12)
However, in this case, the communication result of the first antenna 8 is different in that the vehicle data can be deleted because the vehicle “Y” does not actually exist.

In this fourth pattern as well, as with the method described with reference to FIG.
Vehicle “A” and vehicle “X”, vehicle “B” and vehicle “Z”, vehicle “C” and vehicle “W” are the same vehicle,
As a result of communication by the second antenna 10, the vehicle "Y" (non-ET)
C car) will remain. Therefore, the entrance lane control device 2
No. 4 sequentially corrects the combination, and sets the “first antenna communication content” and the “second antenna communication content” of each vehicle data in the vehicle behavior management queue.
Of "Antenna communication contents".

In the case of the fourth pattern, a ghost car called a vehicle "Y" remains, but the vehicle "Y"
Since the judgment of whether the vehicle is a ghost car or an abnormal car is made by a person such as a maintenance person, a function of deleting and correcting vehicle data retroactively is provided.
Is provided in the panel operation unit 29 of the first embodiment.

FIG. 15 is a flowchart summarizing the correction processing of the vehicle behavior management queue of each pattern described above.

That is, the entrance lane control device 24 sequentially monitors the occurrence of abnormal ETC vehicles, and when an abnormal ETC vehicle occurs (Yes in S201), the entrance lane control device 24
Checks the “vehicle device information” received by the first antenna 8 and the second antenna 10 (S20).
2). Then, from the check result, the first antenna 8
When it is determined that the vehicle of the “on-vehicle device information” of the second antenna 10 is another vehicle (Yes in S203), the entrance lane control device 24 determines whether there is a corresponding vehicle in the preceding and following vehicles “on-vehicle device information”. Is checked (S204).

As a result of this check, if there is a corresponding vehicle (S
(Yes in 205), the entrance lane control device 24 sequentially corrects the combination (S206), and corrects each vehicle data in the vehicle behavior management queue (S207). And
The entrance lane control device 24 transmits the correction data of the communication result with the vehicle-mounted device 6 to the host computer 60 (S20).
8).

Normally, the correction is performed after notifying the communication result to the host computer 60.
In the data format (FIG. 16) for transmitting the result of communication with the on-vehicle device 6 to the host computer 60, the transmission serial number is the same as before the correction, and “correction” is newly added to the section.
"Correction" is set in this category, and the host computer 6
Transmit the correction data to 0.

Also, during the monitoring of the abnormal ETC vehicle (S20
1), if a vehicle exists in the lane even after a certain period of time (Yes in S209), the entrance lane control device 24 checks the “vehicle information” of the preceding and following vehicles (S204).

As a result of this check, if there is a corresponding vehicle (S
(Yes in 205), the entrance lane control device 24 sequentially corrects the combination (S206), and corrects each vehicle data in the vehicle behavior management queue (S207). And
The entrance lane control device 24 transmits the correction data of the communication result with the vehicle-mounted device 6 to the host computer 60 (S20).
8).

Subsequently, the vehicle behavior management operation of the exit lane control device 52 will be described. The exit gate device 4 employs a one-antenna system that performs toll collection processing by wireless communication with an ETC vehicle using one antenna 12.

In this one antenna system, FIG.
As shown in the figure, the first sensor 46 and the second sensor 50 normally detect the vehicle, but the last sensor that detects the passage of the vehicle, here the third sensor 58, separates the vehicle. If the two vehicles are erroneously detected as one, and if the third sensor 58 normally detects two vehicles, the roadside display 54 displays the first communication result as the vehicle. When the vehicle 20 has entered the position of the third sensor 58, the display is deleted when the vehicle 20 has entered the position of the second sensor 50. Similarly, the display and erasure of the roadside display 54 are performed on the second vehicle, but when the second vehicle enters the position of the second sensor 50, the first vehicle is still on the third sensor. If you haven't reached 58,
After the display is erased when the third device enters the position of the third sensor 58, the communication result of the second device is displayed.

As shown in the pattern of FIG. 17, if an erroneous detection occurs in the third sensor 58, it cannot be detected that the second vehicle has entered the position of the third sensor 58.
The display cannot be erased. Then, when the third vehicle passes the position of the third sensor 58 later, the communication result of the second vehicle is deleted. In other words, there is a problem in that the timing of the erasure is shifted, and it becomes impossible to provide appropriate guidance to the user on the roadside display 54 as the purpose.

Therefore, in the toll collection system of this embodiment, the exit lane control device 52 measures the staying time of the vehicle in the lane, and when a certain time is exceeded, the operation panel 65.
A time monitoring function for displaying an error and a function for manually correcting the vehicle behavior management queue are provided, and the vehicle behavior management queue is corrected (changed) by manual input on the operation panel 65 (manual operation by a staff member).

According to this manual input, the second vehicle which is still left (not yet entered the position of the third sensor 58) in the vehicle behavior management queue managed inside the exit lane control device 52. In the behavior data of the vehicle data, the approach to the position of the third sensor 58 and the third sensor 58
It is assumed that the deviation of the vehicle behavior is corrected by correcting each of the exit bits from the position to ON. In addition, by correcting the behavior data, the display of the roadside display 54 which remains without being deleted is inevitably deleted, so that the display deviation can be corrected.

Further, the exit lane control device 52 includes the vehicle 2
The time from when the vehicle enters the lane until the vehicle passes through the position of the third sensor 58 (exits) is monitored, and when the vehicle-mounted device information including the vehicle-specific information is acquired by the antenna 12, or at each sensor. When a certain period of time has elapsed after the detection of the vehicle 20, 46, 50, or 58, a time monitoring function is provided to display on the operation panel 65 that an abnormality (such as an error code) is abnormal. With this time monitoring function, maintenance staff and collection staff can be quickly notified of abnormalities in the lane, so that the deviation correction of the vehicle behavior management queue can be hastened.

Here, with reference to the flowchart of FIG.
The processing performed internally will be described.

When the error code (lane abnormality) is displayed on the display section of the operation panel 65, the attendant notices and operates the ten keys on the operation panel 65 to input the correction data. The behavior data of the corresponding vehicle is corrected in the behavior management queue (S301).

Subsequently, the exit lane controller 52 checks whether or not the display of the preceding vehicle remains on the roadside display 54, and if the display of the preceding vehicle remains (Yes in S302).
s), the display on the roadside display 54 is deleted (S301).

As described above, according to the toll collection system of this embodiment, each sensor 3 is located at the entrance lane of the toll road.
The entrance lane control device 2 is based on the entry / passing behavior data of the vehicle detected by 8, 26, 32, 36 and the onboard equipment information acquired by the first antenna 8 and the second antenna 10.
4 manages vehicle entry and exit with the vehicle behavior management queue,
If there is an error in the vehicle data in the vehicle behavior management queue,
Since the vehicle data before and after that is checked and the combination of vehicle data in the vehicle behavior management queue is changed, the sensor 3
Even in the case where an erroneous detection of 8, 26, 32, 36 occurs, it is possible to manage the vehicles in the lane.

Also, when the vehicle data in the vehicle behavior management queue is corrected after the vehicle data is transmitted from the entrance lane control device 24 to the host computer 60, the classification in the data format to the host computer 60 is "corrected".
The host computer 60 can correct the management data already received by setting and transmitting. Thereby, when the management data of the entrance lane control device 24 and the host computer 60 becomes abnormal, the management data can be restored.

In the exit lane of the toll road, the exit lane control device 52 is based on the vehicle entry / passing behavior data detected by the sensors 46, 50 and 58 and the vehicle-mounted device information acquired by the antenna 12. In the vehicle behavior management queue, the exit lane control device 52 monitors the time when the vehicle enters and exits in the vehicle behavior management queue, and the lane is maintained even if a predetermined time has elapsed since the vehicle was detected by any of the sensors 46, 50, and 58. When a phenomenon (ghost car phenomenon) that a vehicle remains in the vehicle occurs, an error code is displayed on the operation panel 65 operated by the collection staff or the maintenance staff.
Erroneous detection can be noticed by a staff member.

[0125] In addition, when the maintenance staff or the receiving staff performs an error correction operation on the operation panel 65 in response to the error display on the operation panel 65, the deviation of the vehicle behavior management queue is corrected.
Along with this, the deviation of the display of the roadside display 54 is also corrected, so that the maintenance personnel and the receiving staff can quickly respond to the abnormality in the lane such as the erroneous detection of the sensor. Confusion can be prevented.
