Description

  The present invention relates to a fee collection system and a fee collection method. The present invention relates to a system and method for performing automatic fee collection using, for example, ETC (registered trademark).

  In the conventional toll collection system, the control device instructs the start controller to open the gate when the approaching vehicle is a normal ETC vehicle, and close the gate when the entering vehicle is an abnormal ETC vehicle or a non-ETC vehicle ( For example, see Patent Document 1). This instruction is unchanged regardless of whether one vehicle has entered alone or multiple vehicles have entered continuously, and whether or not a vehicle management error has occurred.

  Here, the “normal ETC vehicle” is a vehicle that supports automatic fee collection through ETC communication and can perform automatic fee collection normally. An “abnormal ETC vehicle” is a vehicle that supports automatic fee collection through ETC communication but cannot perform automatic fee collection normally. If an ETC in-vehicle device is installed in the vehicle, it corresponds to automatic fee collection by ETC communication. However, for example, if the ETC card inserted into the ETC on-board device is defective or if communication is not established for some reason, automatic fee collection cannot be performed normally. “Non-ETC vehicle” means that an ETC card is not inserted in the ETC on-board unit or an ETC on-board unit is not installed, so automatic toll collection by ETC communication is not supported. A vehicle that is subject to manual fee collection by a staff member. “Vehicle management deviation” means that there is a difference between the number of detected approaching vehicles and the number of detected leaving vehicles.

JP 2002-74420 A

  As a first event, it is assumed that two approaching vehicles are detected as two vehicles, the first being a normal ETC car and the second being a non-ETC car, have entered continuously. If these two vehicles approach each other and exit, if they are erroneously detected as one tow vehicle, a vehicle management error has occurred. As a second event, when one tow vehicle that is a normal ETC vehicle enters, a towed vehicle is erroneously detected as another vehicle, and two entering vehicles are detected. If the tow vehicle leaves and is detected as one leaving vehicle, a vehicle management error has occurred.

  In the conventional toll collection system, if there are two events as described above, the control device misidentifies that a fictitious non-ETC vehicle exists even though there is no vehicle in the lane. Here, when a normal ETC vehicle has entered as a subsequent vehicle, the control device instructs the start controller to close the gate as a normal operation for a false non-ETC vehicle that has been misidentified. For this reason, there is a possibility that a safety problem occurs when a normal ETC vehicle comes into contact with the gate.

  An object of the present invention is to avoid a safety problem in which a following vehicle contacts a bar when a vehicle management deviation occurs.

A toll collection system according to one aspect of the present invention includes:
A bar that opens when the toll collection for the entered vehicle is completed normally, closes when the toll collection for the entered vehicle does not complete normally, and prevents the vehicle from exiting;
An entry detector for detecting the entry of the vehicle;
A communication unit that performs communication of automatic toll collection for a vehicle whose entry is detected by the entry detection unit;
An exit detection unit for detecting the exit of the vehicle;
When the exit detection unit detects the exit of the first vehicle, the entrance of the second vehicle that does not support automatic toll collection by communication with the communication unit following the entrance of the first vehicle; When the entry of the third vehicle for which toll collection has been normally completed has been detected in order by the entry detection unit, the bar is kept open and the second vehicle is entered following the entry of the first vehicle. When the approach of the vehicle and the approach of the third vehicle are not detected in order by the approach detection unit, the control unit closes the bar.

  In the present invention, when a vehicle management error occurs, the bar is kept open if a vehicle that has successfully completed toll collection has entered as a subsequent vehicle. The problem can be avoided.

In addition, the same code | symbol is attached | subjected to the part which is the same or it corresponds in each figure. In the description of the embodiments, the description of the same or corresponding parts will be omitted or simplified as appropriate.

Embodiment 1 FIG.
Hereinafter, the configuration of the system according to the present embodiment, the operation of the system according to the present embodiment, and the effects of the present embodiment will be described in order.

*** Explanation of configuration ***
Hereinafter, the configuration of a fee collection system 10 which is a system according to the present embodiment will be described with reference to FIG.

  As shown in FIG. 1, the toll collection system 10 includes a bar 20, an entry detection unit 30, a communication unit 40, an exit detection unit 50, and a control unit 60.

  The bar 20 is opened when the toll collection for the entered vehicle is completed normally. The bar 20 is closed when the toll collection for the entered vehicle is not normally completed, and prevents the vehicle from leaving. In the present embodiment, the bar 20 is attached to the start controller 21 installed on both sides of the lane 11 so as to be freely opened and closed. The bar 20 may be attached to a start controller 21 installed only on one side of the lane 11.

  The approach detection unit 30 detects the approach of the vehicle. In the present embodiment, the approach detection unit 30 is a combination of a vehicle detector S1 and a vehicle detector S2 installed on both sides of the lane 11 and before the start controller 21. The vehicle detector S1 detects the entry of the vehicle into the communication area of the first antenna A1, which will be described later. When the vehicle detector S1 detects entry of a vehicle, radio waves are transmitted from the first antenna A1. The vehicle detector S2 detects entry of the vehicle into an area ahead of the communication area of the first antenna A1. When the vehicle detector S2 detects the entry of the vehicle, the transmission of radio waves from the first antenna A1 is stopped. In addition, the approach detection part 30 may be mounted only by vehicle detector S1, and may be mounted in the combination of vehicle detector S1, vehicle detector S2, and another apparatus.

  The communication unit 40 communicates automatic toll collection to the vehicle whose entry is detected by the entry detection unit 30 (in this embodiment, the entry detection unit 30 is specifically the vehicle detector S1). In the present embodiment, the communication unit 40 is the first antenna A1 installed above the lane 11. The first antenna A1 performs wireless communication with the vehicle-mounted device in the vehicle in the region between the vehicle detector S1 and the vehicle detector S2. Note that the communication unit 40 may be implemented by a combination of the first antenna A1 and other devices.

  The exit detection unit 50 detects the exit of the vehicle. In the present embodiment, the exit detection unit 50 is a vehicle detector S <b> 4 installed behind the start controller 21 on both sides of the lane 11. In addition, the exit detection part 50 may be mounted in combination with vehicle detector S4 and another apparatus.

  Here, a vehicle for which toll collection has been completed normally is defined as a “normal vehicle”, and a vehicle for which toll collection has not been completed normally is defined as an “abnormal vehicle”. Regardless of whether toll collection is automatic or manual. Further, a vehicle that does not support automatic fee collection through communication with the communication unit 40 is defined as “non-compliant vehicle”, and a vehicle that supports automatic fee collection through communication with the communication unit 40 is defined as “compatible vehicle”.

  The automatic fee collection communication performed by the communication unit 40 may be any type of communication, but in the present embodiment, it is ETC communication. That is, the communication unit 40 performs ETC communication with the ETC on-vehicle device installed in the vehicle. Therefore, in this embodiment, a normal ETC vehicle corresponds to a normal vehicle and a compatible vehicle, an abnormal ETC vehicle corresponds to an abnormal vehicle and a compatible vehicle, and a non-ETC vehicle for which manual toll collection by a tollgate has been completed successfully. A non-ETC vehicle that corresponds to a normal vehicle and a non-compliant vehicle and a manual toll collection has not been completed normally corresponds to an abnormal vehicle and a non-compliant vehicle.

  The control unit 60 determines from the result of communication by the communication unit 40 whether the toll collection for the vehicle whose entry has been detected by the entry detection unit 30 has been completed normally, and opens and closes the bar 20 according to the determination result. . That is, the control unit 60 determines whether or not the vehicle whose entry has been detected by the entry detection unit 30 is a normal ETC vehicle. The control unit 60 opens the bar 20 when it is determined that the vehicle is a normal ETC vehicle, and closes the bar 20 when it is determined that the vehicle is an abnormal ETC vehicle or a non-ETC vehicle. For non-ETC vehicles, if manual toll collection is completed normally, the bar 20 is opened by operating a tollgate terminal by a tollgate. Note that the control unit 60 may receive information on manual fee collection from the outside for a non-ETC vehicle, and may determine whether manual fee collection has been completed normally from the received information. In this case, the control unit 60 opens the bar 20 if it is determined that the non-ETC vehicle is a normal vehicle, and closes the bar 20 if it is determined that the non-ETC vehicle is an abnormal vehicle.

  When the exit of the first vehicle V1 is detected by the exit detection unit 50, the control unit 60 detects whether the second vehicle V2 that is a non-compliant vehicle enters the normal vehicle after the entry of the first vehicle V1. An approach of a certain third vehicle V3 is an entry detector 30 in this order (in this embodiment, the entry detector 30 is specifically a vehicle detector S2, but may be a vehicle detector S1) If detected, the bar 20 remains open. When the exit of the first vehicle V1 is detected by the exit detection unit 50, the control unit 60 detects the entry of the second vehicle V2 and the entry of the third vehicle V3 following the entry of the first vehicle V1. Are not detected in sequence by the entry detection unit 30, the bar 20 is closed. In the case where “the entry of the second vehicle V2 and the entry of the third vehicle V3 are not sequentially detected by the entry detection unit 30 following the entry of the first vehicle V1,” “the first When the second vehicle V2 has not been detected by the entry detector 30 following the entry of the vehicle V1, the entry of the third vehicle V3 has not been detected by the entry detector 30. " When the entry of the second vehicle V2 is detected by the entry detection unit 30 following the entry of the first vehicle V1, but the entry of the third vehicle V3 is not detected by the entry detection unit 30 " Both are included.

  In the present embodiment, the number of second vehicles V2 is not limited to one. That is, when the exit of the first vehicle V1 is detected by the exit detection unit 50, the control unit 60 allows one or more vehicles to enter the second vehicle V2 following the entry of the first vehicle V1. If the entry detector 30 detects the entry of the third vehicle V3 following the entry of the second vehicle V2, the bar 20 remains open.

  In the present embodiment, the first vehicle V1 may be a compatible vehicle or a non-compliant vehicle. Further, the first vehicle V1 may be a normal vehicle, or may be an abnormal vehicle that is allowed to pass with the bar 20 opened.

  In the present embodiment, the control unit 60 is a lane server 61 installed on one side of the lane 11. The control unit 60 may be implemented by a combination of the lane server 61 and other devices. The lane server 61 may be installed in a remote place away from the lane 11.

  Although not essential, in the present embodiment, the toll collection system 10 further includes a display 12 installed near the vehicle detector S4 on one side of the lane 11, and a second antenna installed above the lane 11. A2. The indicator 12 displays whether or not the vehicle is allowed to pass. When the vehicle detector S2 detects the passage of the vehicle, the display device 12 erases the display content or switches the display content to the content of the following vehicle. The second antenna A2 performs wireless communication with the on-vehicle device of the vehicle within a certain region from the vehicle detector S4 toward the traveling direction of the vehicle.

*** Explanation of operation ***
Hereinafter, the operation of the fee collection system 90 according to the comparative example will be described with reference to FIGS. 2 and 3, and the operation of the fee collection system 10 according to the present embodiment will be described with reference to FIGS. 4 and 5. . The operation of the fee collection system 10 corresponds to the fee collection method according to the present embodiment.

  As shown in FIGS. 2 and 3, the toll collection system 90 according to the comparative example includes a bar 20, a start controller 21, vehicle detectors S1, S2, and S4, a first antenna A1, a second antenna A2, and the like. A lane server not shown is provided. The lane server of the toll collection system 90 is different in operation from the lane server 61 of the toll collection system 10 according to the present embodiment.

  The toll collection system 90 determines whether the approaching vehicle is compatible with ETC by communicating with the first antenna A1 after detecting the approach of the vehicle with the vehicle detector S1. The toll collection system 90 instructs the start controller 21 from the lane server to open the bar 20 when the approaching vehicle is a normal ETC vehicle, or to close the bar 20 when the entering vehicle is an abnormal ETC vehicle or a non-ETC vehicle. . As a result, the normal ETC vehicle exits from the lane 11 without stopping, but the abnormal ETC vehicle and the non-ETC vehicle stop before the start controller 21.

  FIG. 2 shows an example in which a vehicle management deviation occurs in the toll collection system 90 due to erroneous detection with a towed vehicle due to the combination of continuously approaching vehicles.

  2A, the vehicle V1, which is a normal ETC vehicle, a non-ETC vehicle, or an abnormal ETC vehicle, a non-ETC vehicle V2, and a normal ETC vehicle V3 enter the lane 11 in this order.

  In FIG. 2B, when the leading vehicle V1 is a normal ETC vehicle, it is automatically allowed to pass, and when it is a non-ETC vehicle or an abnormal ETC vehicle, it is allowed to pass after manual processing. Since the leading vehicle V1 and the following non-ETC vehicle V2 are approaching, the vehicle detector S4 erroneously detects the vehicle as a towing vehicle. As a result, the subsequent non-ETC vehicle V2 leaves the lane 11 together with the leading vehicle V1.

  In FIG. 2C, the lane server of the toll collection system 90 erroneously recognizes that an imaginary non-ETC vehicle V2 'exists in the lane 11. For the lane server, the non-ETC vehicle V2 and the non-ETC vehicle V2 'are the same vehicle.

  In FIG. 2 (d), the lane server of the toll collection system 90 still misrecognizes that the next vehicle is a non-ETC vehicle V2 ′, so the bar 20 is closed with respect to the subsequent normal ETC vehicle V3. To the start controller 21.

  FIG. 3 shows an example in which a vehicle management deviation occurs in the toll collection system 90 due to erroneous detection due to vehicle separation and recombination of the tow vehicle.

  In FIG. 3A, a tow vehicle V <b> 1 that is a normal ETC vehicle, a non-ETC vehicle, or an abnormal ETC vehicle enters the lane 11. The vehicle detector S1 cannot detect the tow bar of the tow vehicle V1.

  In FIG. 3B, since the boat V2 towed by the tow vehicle V1 cannot communicate with the first antenna A1, the lane server of the toll collection system 90 erroneously determines that the boat V2 is a non-ETC vehicle.

  In FIG. 3C, the normal ETC vehicle V3 enters the lane 11. In the vehicle detector S4, the tow bar of the tow vehicle V1 is detected, and the tow vehicle V1 is determined as one vehicle including the boat V2. As a result, when the tow vehicle V1 is a normal ETC vehicle, the vehicle automatically exits from the lane 11 together with the boat V2 after manual processing when the vehicle is a non-ETC vehicle or an abnormal ETC vehicle.

  In FIG. 3D, the lane server of the toll collection system 90 erroneously recognizes that an imaginary non-ETC vehicle V 2 ′ is present in the lane 11. For the lane server, the boat V2 and the non-ETC vehicle V2 'are the same vehicle.

  In FIG. 3 (e), the lane server of the toll collection system 90 still misrecognizes that the next vehicle is a non-ETC vehicle V2 ′, so the bar 20 is closed with respect to the subsequent normal ETC vehicle V3. To the start controller 21.

  As described above, in the toll collection system 90 according to the comparative example, when a vehicle management error occurs, the lane server misidentifies the opening / closing operation of the bar 20 opposite to the content that should originally be directed to the start controller 21. May be instructed. In particular, when a normal ETC vehicle V3 exits from lane 11 as a following vehicle, the lane server erroneously determines that the following vehicle is a fictitious non-ETC vehicle V2 ′ that does not actually exist due to a misregistration due to vehicle management error. When the closing operation of 20 is instructed, there is a possibility that a safety problem occurs when the normal ETC vehicle V3 contacts the bar 20.

  Therefore, in the toll collection system 10 according to the present embodiment, as a measure for avoiding a situation in which the subsequent normal ETC vehicle comes into contact with the bar 20 when leaving the lane 11, the bar 20 is connected to the first vehicle V1. Even after the start controller 21 is instructed to open, even when the vehicle following the vehicle V1 is a non-ETC vehicle V2, a normal ETC vehicle V3 exists between the vehicle detector S2 and the vehicle detector S4 as a further vehicle. In this case, the lane server 61 causes the start controller 21 to keep the bar 20 open, and prevents the normal ETC vehicle V3 from coming into contact with the bar 20. Here, the number of non-ETC vehicles V2 existing between the subsequent normal ETC vehicle V3 and the first vehicle V1 does not matter. When the second vehicle is an abnormal ETC vehicle, there is no vehicle management deviation due to erroneous detection, so the lane server 61 instructs the start controller 21 to close the bar 20 in the same manner as normal processing.

  FIG. 4 shows an example in which a vehicle management deviation occurs in the toll collection system 10 due to erroneous detection with a towed vehicle due to the combination of continuously approaching vehicles.

  In FIG. 4A, the vehicle V1, which is a normal ETC vehicle, a non-ETC vehicle, or an abnormal ETC vehicle, a non-ETC vehicle V2, and a normal ETC vehicle V3 enter the lane 11 in this order.

  In FIG. 4B, when the leading vehicle V1 is a normal ETC vehicle, the vehicle is automatically allowed to pass, and when it is a non-ETC vehicle or an abnormal ETC vehicle, the vehicle is allowed to pass after manual processing. Since the leading vehicle V1 and the following non-ETC vehicle V2 are approaching, the vehicle detector S4 erroneously detects the vehicle as a towing vehicle. As a result, the subsequent non-ETC vehicle V2 leaves the lane 11 together with the leading vehicle V1.

  In FIG. 4C, the lane server 61 of the toll collection system 10 mistakenly recognizes that an imaginary non-ETC vehicle V <b> 2 ′ exists in the lane 11. For the lane server 61, the non-ETC vehicle V2 and the non-ETC vehicle V2 'are the same vehicle.

  In FIG. 4D, the lane server 61 of the toll collection system 10 has a condition that a normal ETC vehicle V3 exists between the vehicle detector S2 and the vehicle detector S4 as a succeeding vehicle of the non-ETC vehicle V2 ′. Since it is satisfied, the start controller 21 holds the open state of the bar 20.

  FIG. 5 shows an example in which a vehicle management deviation occurs in the toll collection system 10 due to erroneous detection due to vehicle separation and recombination of the tow vehicle.

  In FIG. 5A, a tow vehicle V <b> 1 that is a normal ETC vehicle, a non-ETC vehicle, or an abnormal ETC vehicle enters the lane 11. The vehicle detector S1 cannot detect the tow bar of the tow vehicle V1.

  In FIG. 5B, since the boat V2 towed by the tow vehicle V1 cannot communicate with the first antenna A1, the lane server 61 of the toll collection system 10 erroneously determines that the boat V2 is a non-ETC vehicle. .

  In FIG. 5C, the normal ETC vehicle V3 enters the lane 11. In the vehicle detector S4, the tow bar of the tow vehicle V1 is detected, and the tow vehicle V1 is determined as one vehicle including the boat V2. As a result, when the tow vehicle V1 is a normal ETC vehicle, the vehicle automatically exits from the lane 11 together with the boat V2 after manual processing when the vehicle is a non-ETC vehicle or an abnormal ETC vehicle.

  In FIG. 5D, the lane server 61 of the toll collection system 10 mistakenly recognizes that an imaginary non-ETC vehicle V <b> 2 ′ exists in the lane 11. For the lane server 61, the boat V2 and the non-ETC vehicle V2 'are the same vehicle.

  In FIG. 5 (e), the lane server 61 of the toll collection system 10 has a condition that a normal ETC vehicle V3 exists between the vehicle detector S2 and the vehicle detector S4 as a succeeding vehicle of the non-ETC vehicle V2 ′. Since it is satisfied, the start controller 21 holds the open state of the bar 20.

  As described above, in the toll collection method according to the present embodiment, the control unit 60 that is the lane server 61 opens the bar 20 when the toll collection for the entered vehicle is normally completed, and collects the toll collection for the entered vehicle. Is not completed normally, the bar 20 is closed to prevent the vehicle from leaving. The entry detector 30 including the vehicle detector S1 detects the entry of the vehicle. The communication unit 40 serving as the first antenna A1 performs automatic toll collection communication with the vehicle detected by the approach detection unit 30. The exit detection unit 50 including the vehicle detector S4 detects the exit of the vehicle. When the exit of the first vehicle V1 is detected by the exit detection unit 50, the control unit 60 detects whether the second vehicle V2 that is a non-compliant vehicle enters the normal vehicle after the entry of the first vehicle V1. When the entry of the third vehicle V3 is detected in order by the entry detection unit 30, the bar 20 is kept open, and the entry of the second vehicle V2 and the entry of the second vehicle V2 are continued after the entry of the first vehicle V1. If the entry of the third vehicle V3 is not detected in order by the entry detection unit 30, the bar 20 is closed.

*** Explanation of effects ***
In the present embodiment, when a vehicle management error occurs, the bar 20 is kept open if a vehicle that has successfully completed toll collection has entered as a subsequent vehicle. You can avoid safety problems.

Embodiment 2. FIG.
In the present embodiment, differences from the first embodiment will be mainly described.

  Hereinafter, the configuration of the fee collection system 10 according to the present embodiment will be described with reference to FIG.

  As shown in FIG. 6, the toll collection system 10 includes a bar 20, an entry detection unit 30, a communication unit 40, an exit detection unit 50, and a control unit 60. The bar 20, the entry detection unit 30, the communication unit 40, the exit detection unit 50, and the control unit 60 are the same as those in the first embodiment shown in FIG.

  In the present embodiment, the toll collection system 10 further includes a vehicle detector S3 installed between the vehicle detector S2 and the start controller 21 on both sides of the lane 11, and a vehicle detector S2 on one side of the lane 11. And the indicator 12 installed between the vehicle detectors S3 and the second antenna A2 installed above the lane 11. The vehicle detector S3 detects the passage of the vehicle. The indicator 12 displays whether or not the vehicle is allowed to pass. When the vehicle detector S3 detects the passage of the vehicle, the display device 12 deletes the display content or switches the display content to the content of the following vehicle. The second antenna A2 is the same as that of the first embodiment shown in FIG.

  The operation of the fee collection system 10 according to the present embodiment is the same as that of the first embodiment described with reference to FIGS. 4 and 5. The effect of the present embodiment is the same as the effect of the first embodiment.

Embodiment 3 FIG.
In the present embodiment, differences from the first embodiment will be mainly described.

  Hereinafter, the configuration of the system according to the present embodiment, the operation of the system according to the present embodiment, and the effects of the present embodiment will be described in order.

*** Explanation of configuration ***
Hereinafter, the configuration of the fee collection system 10 which is a system according to the present embodiment will be described with reference to FIG.

  As shown in FIG. 7, the toll collection system 10 includes a bar 20, an entry detection unit 30, a communication unit 40, an exit detection unit 50, a control unit 60, and another communication unit 70. Although not essential, in the present embodiment, the fee collection system 10 further includes a display 12. The bar 20, the entry detection unit 30, the communication unit 40, the exit detection unit 50, and the display 12 are the same as those in the first embodiment shown in FIG.

  The other communication part 70 performs communication for determining whether the vehicle is the second vehicle V2 that is a non-compliant vehicle with respect to the vehicle whose exit is detected by the exit detection unit 50. In the present embodiment, the other communication unit 70 is a second antenna A <b> 2 installed above the lane 11. The second antenna A2 performs wireless communication with the on-vehicle device of the vehicle within a certain region from the vehicle detector S4 toward the traveling direction of the vehicle. The other communication unit 70 may be implemented by a combination of the second antenna A2 and other devices.

  The control unit 60 performs the same operation as that of the first embodiment, and starts measuring the elapsed time Tc when the entry detection unit 30 detects the entry of the vehicle, and the exit detection unit 50 detects the exit of the vehicle. When this is done, the measurement of the elapsed time Tc is terminated. When the approach detection unit 30 detects the entry of the vehicle during the measurement of the elapsed time Tc, the control unit 60 restarts the measurement of the elapsed time Tc. When the elapsed time Tc exceeds the threshold value Tm, the control unit 60 notifies an abnormality.

  In the present embodiment, the control unit 60 calculates the number Nv of existing vehicles from the difference between the number of vehicles whose entry has been detected by the approach detection unit 30 and the number of vehicles whose exit has been detected by the exit detection unit 50. calculate. If the number Nv calculated during the measurement of the elapsed time Tc is 0, the control unit 60 ends the measurement of the elapsed time Tc.

  Further, in the present embodiment, the controller 60 sequentially enters the second vehicle V2, which is a non-compliant vehicle, and the third vehicle V3, which is a normal vehicle, following the entry of the first vehicle V1. Is detected by the entry detection unit 30 and the exit detection unit 50 detects the exit of the first vehicle V1, and then detects exit from the result of communication by the other communication unit 70 following the exit of the first vehicle V1. When it is determined that the vehicle whose exit has been detected by the unit 50 is not the second vehicle V2, the number of the second vehicles V2 is subtracted from the calculated number Nv.

  In the present embodiment, the first vehicle V1 may be a compatible vehicle or a non-compliant vehicle. Further, the first vehicle V1 may be a normal vehicle, or may be an abnormal vehicle that is allowed to pass with the bar 20 opened.

  Also in the present embodiment, the control unit 60 is the lane server 61 installed on one side of the lane 11. The control unit 60 may be implemented by a combination of the lane server 61 and other devices. The lane server 61 may be installed in a remote place away from the lane 11.

*** Explanation of operation ***
Hereinafter, the operation of the fee collection system 10 according to the present embodiment will be described with reference to FIGS. 8, 9, and 10. The operation of the fee collection system 10 corresponds to the fee collection method according to the present embodiment.

  The toll collection system 10 functions as a function for notifying the occurrence of a vehicle management deviation, and the vehicle management number Nv is counted in a certain lane while the vehicle management number Nv is counted even though there is no vehicle in the lane 11. When time has passed, it has a function to issue a lane management abnormality. The residence time in the lane is a threshold value Tm that can be changed by a parameter. The lane server 61 starts counting the elapsed time Tc after the vehicle passes the vehicle detector S1, and cancels the counting of the elapsed time Tc when the vehicle passes the vehicle detector S4. The lane server 61 counts the elapsed time Tc every time the vehicle passes the vehicle detector S1 when the vehicle continuously enters. The lane server 61 issues an abnormality when the elapsed time Tc during counting exceeds the residence time in the lane.

  When a vehicle management deviation occurs, if the vehicle enters at an interval shorter than the residence time in the lane, an abnormality will not be reported forever, and it will be delayed to notice the vehicle management deviation state. Therefore, in the present embodiment, as an improvement measure, the communication result between the vehicle that has passed through the vehicle detector S4 and the second antenna A2 is used, and the presence determination of the imaginary vehicle is performed in the lane server 61. If it is determined, a function for automatically correcting vehicle management deviation is added. That is, as a communication process for the subsequent non-ETC vehicle, if it is an actual non-ETC vehicle, communication should not be performed. However, when the second antenna A2 performs communication, the lane server 61 determines that the subsequent non-ETC vehicle does not communicate. Is determined to be a non-existent non-ETC vehicle, and the vehicle management number Nv is automatically decremented accordingly. Whether this function is enabled or disabled can be switched by parameter setting. Of the non-ETC vehicles, an ETC vehicle-mounted device is installed, but a vehicle in which no ETC card is inserted into the ETC vehicle-mounted device can be detected by the vehicle detector S4 because it can communicate with the second antenna A2. Even if not, it can be detected by the second antenna A2. Therefore, when a non-ETC vehicle in which no ETC card is inserted in the ETC on-board unit is detected from the result of communication by the second antenna A2, instead of using the above function, the vehicle management number Nv is decremented by one. Thus, the vehicle management deviation may be corrected. Alternatively, when a non-ETC vehicle in which no ETC card is inserted in the ETC on-board unit is detected from the result of communication by the second antenna A2, the detected non-ETC is considered by the second antenna A2 not performing communication. An ETC vehicle may be handled in the same manner as a non-ETC vehicle in which no ETC vehicle-mounted device is installed.

  8 to 10 show an example in which a vehicle management shift occurs in the toll collection system 10 due to erroneous detection due to vehicle separation and recombination of the tow vehicle.

  In FIG. 8A, the tow vehicle V <b> 1 that is a normal ETC vehicle enters the lane 11. The tow vehicle V1 is determined to be a normal ETC vehicle by the lane server 61 by communicating with the first antenna A1 after passing the vehicle detector S1. The vehicle management number Nv is calculated as one. The tow vehicle V1 may be a non-ETC vehicle or an abnormal ETC vehicle.

  In FIG. 8B, the vehicle detector S1 cannot detect the tow bar of the tow vehicle V1.

  In FIG. 8C, since the boat V2 towed by the tow vehicle V1 cannot communicate with the first antenna A1, the lane server 61 erroneously determines that the boat V2 is a non-ETC vehicle. The vehicle management number Nv is calculated as two. Since the number of vehicles actually existing in the lane 11 is one, a vehicle management deviation has occurred.

  In FIG. 9D, the normal ETC vehicle V3 enters the lane 11. The normal ETC vehicle V3 is determined to be a normal ETC vehicle by the lane server 61 by communicating with the first antenna A1 after passing through the vehicle detector S1. The vehicle management number Nv is calculated as three. Since the number of vehicles actually existing in the lane 11 is two, the vehicle management deviation continuously occurs.

  In FIG. 9 (e), the tow vehicle V1 passes through the vehicle detector S4 and then communicates with the second antenna A2 to be determined as a normal ETC vehicle by the lane server 61 and exits from the lane 11 as it is. The vehicle management number Nv is calculated as two. Since the number of vehicles actually existing in the lane 11 is one, the vehicle management deviation continuously occurs.

  In FIG. 9F, the vehicle detector S4 detects the tow bar of the tow vehicle V1, and determines that the tow vehicle V1 is a single vehicle including the boat V2. As a result, the boat V2 leaves the lane 11 together with the towing vehicle V1.

  In FIG. 10G, the lane server 61 misidentifies that an imaginary non-ETC vehicle V <b> 2 ′ exists in the lane 11. For the lane server 61, the boat V2 and the non-ETC vehicle V2 'are the same vehicle. The vehicle management number Nv is not changed and is calculated as two. Since the number of vehicles actually existing in the lane 11 is one, the vehicle management deviation continuously occurs.

  In FIG. 10 (h), the lane server 61 satisfies the condition that a normal ETC vehicle V3 exists between the vehicle detector S2 and the vehicle detector S4 as a succeeding vehicle of the non-ETC vehicle V2 ′. Then, the start controller 21 holds the bar 20 in the open state. The normal ETC vehicle V3 is determined to be a normal ETC vehicle by the lane server 61 by communicating with the second antenna A2 after passing through the vehicle detector S4. The lane server 61 recognizes that the following vehicle recognized as the non-ETC vehicle V2 ′ is not the non-ETC vehicle V2 ′ but the normal ETC vehicle V3, and determines that the non-ETC vehicle V2 ′ is a fictitious vehicle. To do. The lane server 61 automatically clears the vehicle management deviation after decrementing the vehicle management number Nv by one. At this time, since the normal ETC vehicle V3 has left the lane 11, the vehicle management number Nv is calculated as zero. Since the number of vehicles actually present in the lane 11 is also zero, the vehicle management deviation has been eliminated.

*** Explanation of effects ***
In the present embodiment, since the vehicle management deviation can be automatically resolved, there is no need to manually clear the vehicle management deviation.
