Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention [Purpose of the Invention (Industrial Application Field) The present invention is suitable for determining the type of vehicle passing on a toll road and preventing illegal passage thereof. Regarding toll road system.

(Prior Art) Tolls on toll roads such as expressways are determined depending on the section used and the type of vehicle passing through.

Therefore, conventionally, a series of procedures have been carried out exclusively as follows.

First, at the entrance gate of a toll road, a staff member waiting in the entrance booth visually observes the vehicle entering the entrance gate and checks the vehicle registration number plate (number plate) of the vehicle.
The type of the incoming vehicle is determined from the color and size of the vehicle, the classification number of the vehicle written on the vehicle registration number plate, the size of the vehicle, the number of axles, etc. Then, the driver operates the ticket issuing machine according to the result of this determination, and issues a ticket corresponding to the vehicle type (recording the vehicle type). Incidentally, this ticket also records entrance gate information such as identification information of the entrance gate, interchange number, ticket issue date and time, staff number, and serial number.

Vehicles using the toll road receive such a toll ticket at the entrance gate and use (pass) the toll road.

At the exit gate, the ticket is handed over to an attendant waiting in the exit booth. The staff places this ticket in a ticket processing device, and checks the vehicle type information that the ticket processing device reads and displays from the ticket with the vehicle type of the passing vehicle that is visually confirmed. Determining whether there is traffic. In addition, the pass ticket processing device compares the travel time of the traffic section used (traversed) by the passing vehicle with the predetermined standard travel time required for the traffic section according to the information read from the pass ticket. , determines whether there is illegal traffic.

After such a determination procedure, the toll ticket processing device calculates the toll for the authorized vehicle according to the section and vehicle type, collects the toll, and issues a receipt. The passing vehicle is allowed to pass through the exit gate.

However, it is extremely difficult to avoid human errors in the above-mentioned visual identification of vehicle types by the attendant. For example, there is a risk that an attendant at an entrance gate may make a mistake in identifying the vehicle type and hand over a ticket that records information on a different vehicle type than the actual vehicle type (or a ticket corresponding to the vehicle type). In addition, the staff at the exit gate may make a mistake in identifying the type of vehicle.

On the other hand, with respect to the above-mentioned travel time, there are various delay factors caused by parking, traffic jams, etc., so it is impossible to absolutely detect illegal traffic based on the travel time.

(Problems to be Solved by the Invention) As mentioned above, the present invention solves the conventional problems such as the difficulty in easily and reliably determining the weight of vehicles traveling on toll roads. The purpose was to create a toll road system that would automatically identify the vehicle type of passing vehicles in response to unmanned toll roads, and that would effectively prevent illegal traffic. Our goal is to provide the following.

[Structure of the Invention] (Means for Solving the Problems) The present invention identifies the type of vehicle that may be traveling on a toll road, for example, the vehicle registration number written on the vehicle registration mark or the vehicle registration number. A database in which shape feature data consisting of externally measurable information and vehicle type data of the vehicle are registered in association with each other, an entrance gate device installed at the entrance gate of the toll road, and an entrance gate device installed at the exit gate of the toll road. A toll passageway system comprising an exit gate device, wherein the entrance gate device measures shape characteristic data of a passing vehicle that has entered the entrance gate, and stores the database according to the measured shape characteristic data of the passing vehicle. The vehicle type data of the passing vehicle is obtained by searching, and a pass that records the vehicle type data searched from this database and the entrance gate information is issued to the passing vehicle.Meanwhile, the exit gate device The shape characteristic data of the passing vehicle that has entered the gate is measured, and the information written on the passing ticket is read and input, and the measured shape characteristic data of the passing vehicle or the information read from the passing ticket is used to measure the shape characteristic data of the passing vehicle that has entered the gate. Search the database. The type of vehicle that entered the exit gate is then determined from the information retrieved from this database.

(Operation) According to the toll road system according to the present invention configured as described above, at the entrance gate, the database is searched according to the measured shape characteristic data of the vehicle, and the vehicle type of the passing vehicle is determined from the information shown from the database. It can be determined reliably.

Then, a ticket is issued that records this vehicle type data and entrance gate information, and at the exit gate, a database is searched according to the information recorded on this ticket or the vehicle's shape characteristic data measured at the exit gate. Therefore, the type of vehicle passing by can be reliably determined from the information registered in the database. Therefore, vehicle type (vehicle type)
It is also possible to effectively calculate and collect tolls on toll roads according to the traffic section.

Moreover, by comparing the information retrieved from the database with the information recorded on the pass ticket or the measured shape characteristic data, it can be determined whether the vehicle is the one specified by the information written on the pass ticket. can be effectively determined,
Based on this determination result, it becomes possible to effectively prevent illegal passage on the toll road.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic configuration diagram of a toll road system according to an embodiment, where 1 is an entrance gate device installed at the entrance gate of the toll road, and 2 is an exit gate device installed at the exit gate of the toll road. Further, 3 and 4 are databases respectively provided in the entry gate device W11 and the exit gate device fff2. These databases 3 and 4 may be integrated and provided in, for example, a toll road management center.

Further, 5 is a toll ticket issued to vehicles passing on the toll road.

Now, database 3.4 above pairs the vehicle type number with shape characteristic data that can be measured from the outside of the vehicle, or vehicle registration number, for all vehicles that may be traveling on toll roads, and stores this information for each vehicle. It is constructed by recording on one form for each vehicle. Furthermore, the shape characteristic data of the above vehicle is as follows:
For example, the total length, width, height, wheelbase, tread, number of axles, number of II wheels, etc. of the vehicle are included. For example, the database 3.4 is constructed by creating the above-mentioned form regarding the vehicle when registering the vehicle at the Land Transport Bureau, and sequentially filing this form.

Now, the entrance gate VR11 is configured as follows.

When a vehicle enters the entrance gate, this is detected by the vehicle sensing device 1.
1 is sensed and the vehicle shape measuring device 12 is activated. The vehicle shape measuring device 12 includes, for example, a TV camera and an image processing device, and processes an input image of a vehicle that has entered the entrance gate to obtain its shape characteristic data, that is, the aforementioned total length, total width, total height, We are looking for wheelbase, tread, number of axles, number of wheels, etc. Furthermore, the information written on the vehicle registration number plate (license plate) of the passing vehicle is subjected to character recognition processing to detect the vehicle registration number including the vehicle type classification number, etc. The search device 13 searches the database 3 according to the vehicle shape characteristic information measured in this way, and extracts the form 14 of the corresponding vehicle.

Incidentally, the registration device 15 registers a new vehicle form in the database 3 and stores special information in the database 3.
This is for registering.

In this way, when the corresponding form 14 that records detailed vehicle information about the vehicle that entered the entrance gate is searched and extracted from the database 3, the ticket issuing agency 16 stores all or part of this corresponding form 14. The information and entrance information 17 unique to the entrance gate are input, and a ticket 5 recording these information is issued to the passing vehicle.

Specifically, the ticket issuing machine 16 uses the vehicle type identification information and vehicle shape information indicated by the corresponding form 14 retrieved from the database 3, or the vehicle registration number that specifies the vehicle, and the incoming law report 17. The interchange number and the like are recorded magnetically or perforated on the pass 5. At the same time, the interchange name, ticket issue date and time, ticket issue serial number, etc. are printed and recorded on the pass/pass 5, and this is issued to passing vehicles. Therefore, in addition to the information of the entrance gate (interchange number), information that can specify the type of vehicle (vehicle information) is recorded on the ticket 5.

A vehicle entering the entrance gate receives such a toll ticket 5 and uses (passes) the toll road.

On the other hand, the exit gate device WI2 is constructed as follows.

The pass ticket reading device 21 reads and inputs the information recorded on the pass ticket 5 carried by the vehicle after entering the exit gate, and provides the input information to the search device 22 . The search device 22 searches the database 4 according to, for example, vehicle information obtained from the ticket 5, and extracts the corresponding form 23. It goes without saying that this database 4 has the same configuration as the database 3 described above. Further, the registration device 24 functions similarly to the registration device 1 described above.

Further, this exit gate device 2 is also provided with a vehicle sensing device 25 and a vehicle shape measuring device 26, and shape characteristic data of a vehicle that has entered the exit gate is obtained. Then, this measured shape feature data and the database 4
A comparison is made with the corresponding form 23 retrieved from , and it is determined whether the vehicle is the vehicle indicated by the vehicle information recorded on the ticket 5 or not. At the same time,
The vehicle type is determined from the information of the corresponding form 23 retrieved from the database 4.

According to the result of such determination processing, the toll calculation device 27 selects the corresponding form 2 when the vehicle that entered the exit gate is the vehicle recorded on the pass ticket 5 (when it is not an illegal passing vehicle).
3, obtains the entrance gate information recorded on the toll ticket 5 from the toll ticket reading device 121, and calculates the toll fee by calculating the usage (passage) section of the toll road, etc. The toll thus calculated is displayed on the toll display device 28, and the toll is collected from the passenger of the vehicle.

Thus, in a toll road system configured in this way,
The procedure shown in FIG. 2 is performed at the entrance gate and the exit gate.

That is, if the vehicle registration number written on the vehicle registration number plate is detected as shape characteristic data of the vehicle, at the entrance gate, as shown in FIG. The registration number marker is inputted (step a). Then, the input image is recognized and processed to obtain the vehicle registration number written on the vehicle registration number plate (
Step b). A database search is performed according to the vehicle registration number obtained in this way (step C),
A vehicle model number indicating the vehicle model of the vehicle is obtained (step d
).

Through this series of processing (database search), automatic determination of the vehicle type is performed instead of the conventional visual inspection by an attendant. Then, this automatically determined vehicle type number is recorded on the pass 5 together with the entrance gate information as the pass ticket information, and the pass 5 is issued (step e).

On the other hand, as shown in FIG. 2(b), at the exit gate, the vehicle information recorded on the ticket 5 is read and input (step f), and the vehicle model number recorded there is extracted (step Q). , and searches the database according to this vehicle model number (step h) to obtain the vehicle registration number of the vehicle (step i). Therefore, at the exit gate, the vehicle type is automatically determined based on the information written on the ticket 5, instead of the conventional visual determination of the vehicle type by an attendant.

Also, at this exit gate, the shape characteristic data of the vehicle that has entered the exit gate is measured, that is, the am input of the vehicle registration number sign is performed (step j), and the vehicle registration number written there is extracted. (Step k>. Then, the vehicle registration number retrieved from the database based on the information written on the ticket 5 is compared with the vehicle registration number determined by the shape measurement (Step 2).
, illegal traffic is determined.

To explain the determination of illegal traffic, the vehicle type number retrieved from the database according to the vehicle registration number at the entrance gate is recorded on the passing ticket 5, and the sleeping type number recorded on the said passing ticket 5 is recorded at the exit gate. If the database is searched according to the above, the vehicle registration number obtained from the vehicle type number at the entrance gate will definitely be included in the information searched as the corresponding form from the database. Despite this, among the vehicle registration numbers retrieved from the database,
If the vehicle registration number measured at the exit gate does not exist, the vehicle model number used to search the database does not indicate the model of the vehicle that entered the exit gate. Therefore, the ticket 5 is not issued to the vehicle that entered the exit gate. From this, it becomes clear that the ticket was obtained illegally, and that the vehicle is trying to illegally pass through the toll passage.

Therefore, according to this system, it is possible to automatically determine the type of vehicle passing on a toll road, and at the same time, it is possible to effectively use the vehicle information registered in the database to reliably detect illegal traffic. It becomes possible.

By the way, in the embodiment described above, the database is searched according to the vehicle information read and input from the pass ticket, but for example, as shown in FIG. The database can also be configured to be searched according to the shape characteristic data of the vehicle. Then, the vehicle information retrieved from this database 4 and the vehicle information read and input from the pass ticket 5 may be collated.

That is, as shown in FIG. 4, the vehicle registration number plate of the vehicle that has entered the exit gate is input as an image (step m), and the input image is recognized and recorded on the vehicle registration number plate. Obtain vehicle registration number (step n)
. The database is searched according to the vehicle registration number obtained in this way (step 0), and a model number indicating the model of the vehicle is obtained (step p).

Through this series of processing (database search), the vehicle type is automatically determined, instead of the conventional visual inspection by an attendant. On the other hand, the vehicle information written on the ticket 5 is read and input (step q), and the vehicle model number written therein is extracted (step r>).Then, these vehicle model numbers are compared and verified with each other (step Q). , illegal traffic may be determined.

To explain the determination of illegal traffic, the vehicle model numbers retrieved from the database according to the vehicle registration numbers at the entrance gate and the exit gate are always the same as long as the vehicles (vehicle registration numbers) are the same. Therefore, the vehicle type information determined at the entrance gate is recorded on the ticket, and when it is compared with the vehicle type information determined at the exit gate, if there is a difference in the vehicle type information, the ticket is recorded for the vehicle that entered the exit gate. This means that it was not issued to.

From this, it is detected that the ticket was obtained illegally and that the vehicle that entered the exit gate is attempting to illegally pass through the toll road.

Even if the system is configured in this way, the same effects as in the previous embodiment can be achieved.

Note that the present invention is not limited to the embodiments described above. For example, among the form information for each vehicle registered in the database, the number of shape feature information is greater than the standby information that can be measured by the vehicle shape measuring device, and only the necessary information (shape feature data) is stored in the database. It would be convenient if it could be used selectively to perform database searches.

Further, vehicle information retrieved and extracted from the database according to other shape characteristic data may be recorded on the ticket. In addition, the present invention can be modified in various ways without departing from the gist thereof.

[Effects of the Invention] As explained above, according to the present invention, it is possible to easily and accurately identify the vehicle type of a vehicle traveling on a toll road by effectively utilizing vehicle information recorded in a database. In addition, it is possible to detect illegal traffic using vehicle information retrieved from a database, which brings about great practical effects.
