Description

  The present invention relates to a toll collection system for preventing unauthorized use of a vehicle-mounted device in an automatic toll collection system (ETC system: Electronic Toll Collection System) on a toll road, and a method for inhibiting unauthorized passing vehicles.

  In the conventional automatic toll collection system, for vehicles that did not collect tolls, the lane entry blocking rod is closed to warn the driver that the lane cannot be passed and the entry blocking rod is broken through. Then, there is a system that provides evidence that the vehicle shown in the captured image is an unauthorized vehicle by imaging the vehicle at the moment when the entry blocking rod is forced through the vehicle about to pass ( For example, see Patent Document 1). In this system, it is a precondition for detecting an unauthorized vehicle that the unauthorized vehicle comes into contact with the entry blocking rod and breaks through.

May be judged. In this case, since the approach blocking rod comes into contact with the vehicle, there is also a problem that the vehicle on which the correct vehicle-mounted device is mounted is damaged.

  The present invention has been made to solve such a problem, and it is intended to obtain a toll collection system that correctly detects an unauthorized vehicle having vehicle type information different from a registered vehicle type set in the vehicle-mounted device and suppresses the passage of the unauthorized vehicle. Objective.

  The toll collection system according to the present invention is installed at a plurality of locations on a toll road, transmits / receives information to / from the vehicle-mounted device, and outputs the received number information, vehicle type information, and information between the roadside device and the roadside device. The license plate reader for reading the license information and the vehicle type based on the license information read by the license plate reader, and the determined vehicle type information Compared with the vehicle type information output from the roadside machine, the vehicle type information that does not match the vehicle type is determined to be an unauthorized vehicle, and the vehicle type determination device that outputs the number information of the determined unauthorized vehicle, and the unauthorized type output from the vehicle type determination device When vehicle number information is accumulated sequentially and the same illegal vehicle number information is accumulated more than a predetermined number of times, -When the central device that outputs the information, the number information of the unauthorized vehicle output from the central device, and the number information transmitted from the vehicle-mounted device and received by the roadside device match, And a control device for blocking traffic.

  According to the present invention, it is possible to correctly detect an unauthorized vehicle in which vehicle type information different from the registered vehicle type is set in the vehicle-mounted device, and to suppress the passage of the unauthorized vehicle.

  In the figure, an ETC vehicle 1 is an automobile equipped with an in-vehicle device 2, and an ETC vehicle 1b is an automobile equipped with an on-vehicle device 2b. Here, it goes without saying that the ETC vehicles 1, 1b may be motorcycles. The ETC vehicle 1 enters the toll road section from the entrance lane 101 of the toll road 100. Further, after passing through the toll road 100, the vehicle exits from the exit lane 102 outside the section of the toll road. In the figure, an ETC vehicle 1b indicates a vehicle passing through the exit lane 102. In addition, in the exit lane 102, the entry blocking bar 13 is opened.

  The vehicle-mounted devices 2 and 2b communicate wirelessly with the roadside antenna devices 4 and 10, and road-to-vehicle communication is performed for transmitting and receiving information between the roadside antenna devices 4 and 10. By this road-to-vehicle communication, the roadside antenna devices 4 and 10 send various roadside machine information such as an identification number (roadside machine ID number) individually assigned to the roadside machine in advance and charged fee information to the vehicle-mounted devices 2 and 2b. Downlink to The roadside machine information is stored in a memory provided in the roadside machine. In addition, the vehicle-mounted devices 2 and 2b can receive the identification number (vehicle-mounted device ID number), vehicle type information, number plate number information, and the roadside device received from the passed roadside device by road-to-vehicle communication. Various in-vehicle device information such as an ID number and ETC card information indicating an ETC card identification number are uplinked to the roadside antenna devices 4 and 10. Onboard equipment information is stored in a memory provided in the onboard equipment.

Next, the operation of the fee collection system according to the first embodiment will be described.
First, when the ETC vehicle 1 enters the entrance lane 101 of the toll road 100, it passes through the vehicle detector 3. Then, the vehicle detector 3 detects the passage of the ETC vehicle 1 and outputs a vehicle detection signal indicating that the passage of the vehicle is detected to the roadside control device 6. When the roadside control device 6 receives the vehicle detection signal, it starts the communication operation of the roadside antenna device 4 and the photographing operation of the license plate reader 5. When the communication operation of the roadside antenna device 4 is activated, a transmission request signal is transmitted from the roadside antenna device 4 to the vehicle-mounted device 2 of the ETC vehicle 1 by the communication control of the roadside control device 6. When receiving the transmission request signal, the vehicle-mounted device 2 transmits a response signal. Upon receiving this response signal, the roadside antenna device 4 starts road-to-vehicle communication with the vehicle-mounted device 2 and transmits / receives information to / from the vehicle-mounted device 2 through communication control of the roadside control device 6. Through this road-to-vehicle communication, the road-side control device 6 passes the road-side antenna device 4 through the vehicle-mounted device ID number, vehicle type information, number information, and the road-side device ID number of the passed road-side device and its log (history information). ) Etc. and ETC card information. The roadside control device 6 associates the number information of the ETC vehicle 1 with the vehicle type information and transmits it to the vehicle type determination device 7. Further, the roadside control device 6 transmits the vehicle-mounted device information and the ETC card information of the ETC vehicle 1 to the central device 21 via the communication line 20. Central device 21 stores in-vehicle device information and ETC card information of ETC vehicle 1 received from roadside control device 6 via communication line 20 in a storage device.

  When the photographing operation of the license plate reader 5 is activated, the license plate reader 5 photographs the front surface portion and the license plate portion of the ETC vehicle 1. FIG. 2 is an example of an image obtained by photographing the front surface of the ETC vehicle 1. The license plate reader 5 reads the number information of the license plate by image processing such as edge extraction processing, binarization processing, template matching processing, etc. based on the photographed license plate image. The license plate reader 5 associates the read number information with the license plate image, and outputs them to the vehicle type identification device 7.

  The vehicle type discriminating device 7 discriminates the vehicle type based on the number information output from the license plate reader 5. For example, a 5 number vehicle such as a license plate “5 *” or “5 **” is a small vehicle, and a 3 number vehicle such as a license plate “3 *” or “3 **” is normal. If the vehicle is a 1-number vehicle such as a license plate “1 *” or “1 **”, it is determined as a large vehicle. The vehicle type identification device 7 compares the vehicle type information determined based on the output of the license plate reader 5 with the vehicle type information output from the roadside control device 6. In this comparison, the number information associated with the vehicle type information determined based on the output of the license plate reader 5 matches the number information associated with the vehicle type information output from the roadside control device 6. Done. As a result of the comparison, if the vehicle type information determined based on the output of the license plate reader 5 matches the vehicle type information output from the roadside control device 6, the vehicle type determination device 7 stops the comparison process. On the other hand, as a result of the comparison, if the vehicle type information determined based on the output of the license plate reader 5 and the vehicle type information output from the roadside control device 6 do not match, the vehicle type determination device 7 does not match the vehicle type information. The time when the determination is performed is associated with the number information of the ETC vehicle 1, and the number information of the unauthorized vehicle is output together with the number plate image. The number information and the number plate image of the unauthorized vehicle with time information output from the vehicle type determination device 7 are transmitted to the central device 21 via the communication line 20.

  Further, when the ETC vehicle 1b enters the exit lane 102 of the toll road 100, it passes through the vehicle detector 9. Then, the vehicle detector 9 detects the passage of the ETC vehicle 1b and outputs a vehicle detection signal indicating that the passage of the vehicle is detected to the roadside control device 8. When the roadside control device 8 receives the vehicle detection signal, the roadside antenna device 10 starts the communication operation of the roadside antenna device 10 and the photographing operation of the license plate reader 14. When the communication operation of the roadside antenna device 10 is started, a transmission request signal is transmitted from the roadside antenna device 10 to the vehicle-mounted device 2b of the ETC vehicle 1b by the communication control of the roadside control device 8. When the on-vehicle device 2b receives this transmission request signal, it transmits a response signal. Upon receiving this response signal, the roadside antenna device 10 starts road-to-vehicle communication with the vehicle-mounted device 2b, and transmits / receives information to / from the vehicle-mounted device 2b by communication control of the roadside control device 8. By this road-to-vehicle communication, the road-side control device 8 via the road-side antenna device 10 has the vehicle-mounted device ID number of the ETC vehicle 1b, vehicle type information, number information, and the road-side device ID number of the passed road-side device and its log (history information). ) Etc. and ETC card information. The roadside control device 8 associates the number information of the ETC vehicle 1b with the vehicle type information and transmits the information to the vehicle type determination device 15. The roadside control device 8 transmits the vehicle-mounted device information and the ETC card information of the ETC vehicle 1 b to the central device 21 via the communication line 20. Central device 21 stores in-vehicle device information and ETC card information of ETC vehicle 1b received from roadside control device 8 via communication line 20 in a storage device.

  When the photographing operation of the license plate reader 14 is activated, the license plate reader 14 photographs the front surface portion and the license plate portion of the ETC vehicle 1b. The license plate reader 14 reads the number information of the license plate by image processing such as edge extraction processing, binarization processing, template matching processing, etc. based on the photographed license plate image. The license plate reader 14 associates the read number information with the license plate image and outputs them to the vehicle type identification device 15.

  The vehicle type discriminating device 15 discriminates the vehicle type in the same manner as the vehicle type discriminating device 7 based on the number information output from the license plate reader 14. The vehicle type determination device 7 compares the vehicle type information determined based on the output of the license plate reader 14 and the vehicle type information output from the roadside control device 8 in the same manner as the vehicle type determination device 7. As a result of the comparison, if the vehicle type information determined based on the output of the license plate reader 14 matches the vehicle type information output from the roadside control device 8, the vehicle type determination device 15 stops the comparison process. On the other hand, as a result of the comparison, if the vehicle type information determined based on the output of the license plate reader 14 and the vehicle type information output from the roadside control device 8 do not match, the vehicle type determining device 15 does not match the vehicle type information. The time when the determination is performed is associated with the number information of the ETC vehicle 1b, and the number information of the unauthorized vehicle is output together with the number plate image. The number information and the number plate image of the unauthorized vehicle with time information output from the vehicle type determination device 15 are transmitted to the central device 21 via the communication line 20.

  The central device 21 stores the number information and the number plate image of the unauthorized vehicle with time information received from the vehicle type discriminating devices 7 and 15, respectively, and stores the number information of the unauthorized vehicle in association with the time information. . Whenever the central device 21 receives the number information and the number plate image of the unauthorized vehicle output from all the vehicle type identification devices installed on the toll road as a pair with the roadside control device, the central device 21 converts the unauthorized vehicle number information into time information. The number information is sequentially stored in association with each other. At the same time, each time data is stored in the storage device, the number of times of unauthorized vehicle number information corresponding to the same number information is stored (output of the same unauthorized vehicle number information that is output at a different time from an arbitrary vehicle type discriminating device). Count). This count is the number of times of acquisition of number information of unauthorized vehicles confirmed by a plurality of vehicle type discriminating devices during traveling within one continuous traffic time on the same toll road, and when the toll road is passed in different traffic periods, The number of counts increases according to the number of times of obtaining the number information of the unauthorized vehicles confirmed at different times by the same vehicle type discrimination device.

When the number information of the illegal vehicle output from the vehicle type identification device (all the vehicle type identification devices including the vehicle type identification devices 7 and 15) is accumulated more than a predetermined number of times, the central device 21 adds the number to the unauthorized vehicle number information. The plate images are associated with each other, stored in the storage device as unauthorized traffic vehicle information, and output.
Thus, an ETC vehicle that has performed unauthorized traffic can be identified as an unauthorized vehicle, and number information and a license plate image of the unauthorized vehicle can be obtained.

  Thus, in the toll collection system of this embodiment, even if the vehicle equipped with the vehicle-mounted device that normally performs the charging process with the roadside device is equipped with an unauthorized vehicle-mounted device that does not fit the vehicle, An unauthorized vehicle can be determined. For example, when a large vehicle carrying an on-vehicle device of a normal vehicle passes, the unauthorized traffic can be detected.

Further, the central device 21 can identify a vehicle that has been cheated multiple times as a fraudulent vehicle instead of a single fraud based on the accumulated number information of the unauthorized vehicle. Can be reduced. As a result, it is possible to notify the notification of fraudulent vehicle fraud and the billing notification of fraud payment for fraud without error.
In addition, when using a license plate reader, a roadside machine, and a vehicle type discrimination device, it is difficult to discriminate the vehicle type with 100% accuracy. For this reason, the effect of reducing the misjudgment of an unauthorized vehicle is acquired by determining the suitability of an unauthorized vehicle over multiple times.

Next, the handling of unauthorized traffic vehicle information output from the central device 21 will be exemplified.
The unauthorized passing vehicle information output from the central device 21 is output to the management station server 30, the public institution server 31, and the settlement processing device 23. The management station server 30 uses the unauthorized traffic vehicle information from, for example, the number information of the unauthorized vehicle by using the vehicle registration inquiry to the Land Transport Bureau or the inquiry to the organization registered as a member. (User) can be clearly identified.
In addition, it is possible to specify the issue destination (notification destination) of the inquiry document for the illegal vehicle, and to issue and send the inquiry document. By sending this inquiry document, it is well-known that a notification from the road company will be given if illegal traffic is committed, leading to the effect of preventing unauthorized traffic.

  Further, the checkout processing device 23 obtains unauthorized vehicle number information and time information from the central device 21 as unauthorized passing vehicle information. Further, the central device 21 refers to the in-vehicle device information of the ETC vehicle 1 received from the roadside device, and obtains the history information of the roadside device ID number through which the vehicle has passed from the on-vehicle device information corresponding to the number information of the unauthorized vehicle. . The administrator of the central device 21 outputs this history information through the operation terminal 22 and determines how much the illegal vehicle has illegally escaped every time the toll road travels based on the output history information. be able to. As a result, the administrator of the central device 21 calculates the fee to be charged, issues a payment bill, and gives the payment bill to the unauthorized user of the toll collection system that has illegally passed the toll road. Can be sent. At this time, a reminder can be issued to an unauthorized person who does not pay a fee even if an invoice is issued.

Further, the settlement processing device 23 performs billing processing based on the information transmitted from the vehicle-mounted device and received by the roadside device, and billing processing such as vehicles that cannot be settled due to insufficient bank balance or inconsistent ETC card or illegal vehicles. It is also possible to output the number information obtained from the vehicle-mounted device of the vehicle that causes an error to the roadside control device as the number information of the unauthorized vehicle.
For example, the checkout processing device 23 registers the unauthorized vehicle number information output from the central device 21 in the negative table, and stores the information in the storage device as an in-vehicle device that causes an error in the billing process. The settlement processing device 23 transmits the registered negative table to the roadside control device 8. This negative table is a list in which the number information of all unauthorized vehicles is recorded. In addition to the unauthorized vehicles identified by the central device 21, the administrator receives a notification from the management station and inputs the information through the operation terminal 22. Contains information on unauthorized vehicles. The roadside control device 8 transmits the negative table output from the central device 21 to the start control device 11. The start control device 11 stores the received negative table in the storage device.

FIGS. 3A and 3B are views showing (a) a state where the entry prevention bar 13 is opened and (b) a state where the entry prevention bar 13 is closed in the exit lane of the toll road.
When the ETC vehicle 1b enters the exit lane 102, the roadside control device 8 starts road-to-vehicle communication with the vehicle-mounted device 2b as described above. When the roadside control device 8 receives the vehicle-mounted device information transmitted from the vehicle-mounted device 2b through the road-to-vehicle communication with the vehicle-mounted device 2b, the roadside control device 8 sends the number information included in the vehicle-mounted device information to the start control device 11. Upon receiving the number information output from the roadside control device 8, the start control device 11 performs a negative check. In this negative check, the number information included in the vehicle-mounted device information received from the vehicle-mounted device 2b is compared with the number information of the illegal vehicle included in the negative table. If the compared number information matches as a result of the negative check, it is determined that the vehicle is an unauthorized vehicle, and the entry blocking rod 13 is tilted and closed as shown in FIG. 3B, and the passage of the exit lane 102 is closed. Thus, the passage of the passing vehicle (ETC vehicle 1b) is blocked. On the other hand, if the compared number information does not match as a result of the negative check, the negative check process is stopped as it is. In this case, as shown in FIG. 3 (a), the entry blocking bar 13 goes up and remains open. In this way, the start control device 11 can close the entry blocking bar 13 only for the unauthorized vehicles registered in advance in the negative table.
At this time, a roadside indicator (not shown) may be provided to display that the vehicle is an unauthorized vehicle from the start control device 11 on the roadside indicator. It is also possible to transmit information indicating that the vehicle is an unauthorized vehicle from the start control device 11 to the vehicle-mounted device 1b via the road-side control device 8, and to announce that the vehicle is an unauthorized vehicle through a speaker connected to the vehicle-mounted device 1b. It is.
Needless to say, the start control device 11 may be integrated with the roadside control device 8, or a part of the functions of the start control device 11 may be part of the constituent functions of the roadside control device 8.

Of course, the start control device 11 can also control the opening and closing of the entry blocking rod 13 by receiving the number information read by the license plate reader 14. In this case, a negative check is performed to compare the number information of the ETC vehicle 1b read by the license plate reader 14 with the number information of the illegal vehicle included in the negative table. Then, close the approach block 13 by defeating it.
In addition, the number information included in the vehicle-mounted device information received from the vehicle-mounted device 2b during the negative check, the number information of the ETC vehicle 1b read by the license plate reader 14, and the number information of the illegal vehicle included in the negative table However, it is also possible to determine that the vehicle is an unauthorized vehicle and close the entry blocking bar 13 by defeating only when they all match. In this way, when an illegal vehicle passes, the entry blocking rod 13 can be closed more reliably. Therefore, even if a regular vehicle that is not an unauthorized vehicle passes, the entry blocking rod 13 is mistakenly entered. Can be further reduced.

  In this way, the central device 21 can suppress unauthorized vehicles by registering a negative table via the settlement processing device 23 for an unauthorized person who does not pay a fee.

  In addition, the central device 21 can also notify the enforcement agency of the number information and license plate image of the unauthorized vehicle through the public institution server 31. This makes it possible to forcibly control an unauthorized person who does not pay a fee.

Next, FIG. 4 is a diagram showing a processing flow of the fee collection system according to the first embodiment. In this toll collection system, the following steps 1 to 4 are processed to prevent unauthorized vehicles from passing.
(1) Step 1: A number reading step of reading number plate number information with a license plate reader for a passing vehicle (ETC vehicle) that transmits and receives information by communication between the vehicle-mounted device and the roadside device.
(2) Step 2: Based on the number information read by the license plate reader in Step 1, the vehicle type is determined using the vehicle type determination device, and the determined vehicle type and the vehicle type obtained by communication between the vehicle-mounted device and the roadside device Vehicle type determination step of determining a vehicle in which the vehicle numbers do not match as an unauthorized vehicle and outputting number information of the unauthorized vehicle.
(3) Step 3: Number information of unauthorized vehicles output from the vehicle type discriminating device in Step 2 is sequentially accumulated, and when the same unauthorized vehicle number information is accumulated more than a predetermined number of times, the unauthorized vehicle number information And an unauthorized notification step of notifying the management station.
(4) Step 4: Unauthorized vehicle traffic that prevents passage of a passing vehicle when the number information of the unauthorized vehicle output in Step 3 matches the number information transmitted from the vehicle-mounted device and output from the roadside device. Blocking step.

  As described above, the toll collection system according to the first embodiment is installed at a plurality of locations on the toll road, transmits and receives information to and from the vehicle-mounted device, and outputs the received number information and vehicle type information. For a passing vehicle that transmits and receives information to and from the roadside machine, a license plate image is taken and a vehicle type is determined based on the number plate reader that reads the number information and the number information read by the number plate reader. Comparing the determined vehicle type information with the vehicle type information output from the roadside device, determining that the vehicle type information is inconsistent, determining the vehicle as an unauthorized vehicle, and outputting the determined unauthorized vehicle number information; and The number information of unauthorized vehicles output from the vehicle type discriminator is sequentially accumulated, and the number information of the same unauthorized vehicles is accumulated more than a predetermined number of times. When the central device that outputs the number information of the unauthorized vehicle, the number information of the unauthorized vehicle that is output from the central device, and the number information that is transmitted from the in-vehicle device and received by the roadside device, And a control device for blocking the passage of the passing vehicle by an approach blocking bar.

  Accordingly, it is possible to correctly detect an unauthorized vehicle in which vehicle type information different from the registered vehicle type is set in the vehicle-mounted device, and to suppress the passage of the unauthorized vehicle.
