Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a toll road fraud prevention device capable of preventing illegal passage on a toll road.

Many toll roads with multiple sections use toll systems based on vehicle type and section of use.

In other words, on toll roads with this kind of toll system, a toll ticket is issued to passing vehicles at the toll gate entrance, which records the entrance information necessary for toll calculation, such as the toll gate number, date, time, and vehicle type, and this ticket is issued at the toll gate exit. The system receives the pass, reads the information recorded on the pass, calculates the toll based on the read information, and receives the toll.

However, this has become a problem as some passersby cheat on each other by cheating on the route they are passing and thereby cheating on the toll fee.

Conventionally, it is said that there have been three types of frauds committed by passersby on toll roads, which can be broadly classified as described below.

■ Exchange of toll tickets This takes the form shown in (1) ■ and @ in Figure 1. For example, in the example of ■, a driver heading from toll gate B to toll gate Y and Y
Drivers heading from toll plaza to toll plaza B exchange tickets at intermediate point M (for example, a drive-in) and get off at 2 and A, avoiding toll plaza Y or B. In this case,
Since you are using the minimum section of each route, you can travel to your destination perigee with the minimum toll. In example O, a driver heading from tollgate A to tollgate 2 and a driver heading from tollgate 2 to tollgate A exchange tickets at intermediate M, avoid tollgate 2 or A, and return to tollgate Y and B. This is a case of failure. In this case as well, you can pass at the minimum toll as in case ■.

■ Use of pass ticket This is the form shown in (2) ■ and O in Figure 1. For example, in the case of ■, a vehicle enters from Y toll gate and loses its pass when getting off at A toll gate. Then, at the tollgate, pay the farthest toll (the toll from the tollgate to the farthest tollgate on the expressway) when you process the lost toll ticket. At this point, you will have to pay the toll for the section Z-A which is one more than the actual section Y-A, but you will be able to obtain a toll ticket issued by the Y toll gate. On the return trip, enter at toll gate B, get off at toll gate 2, and pay the toll using the ticket issued by toll gate Y that you obtained on your outbound trip.

As a result, on the return trip, the section to be used will be between Y and Z, allowing passengers to travel at the lowest toll. Since the pass ticket remains in hand even at this point, they use it to repeat the above-mentioned fraud.

Case (2) @ is similar; a vehicle entering from toll gate 2 loses its toll ticket when getting off at toll gate A, and the farthest toll (Jt. Pay the toll (from the toll booth to the farthest toll booth on the expressway).

On the return trip, enter at toll gate A, get off at toll gate Y, and pay the toll using the ticket issued at toll gate 2 that you obtained on your outbound trip.

As a result, on the return trip, the section to be used is between Z and Y, allowing the user to travel at the minimum toll. Since the pass ticket remains in hand even at this point, they use it to repeat the above-mentioned fraud.

This method of using a pass ticket machine can be done independently, and since one pass ticket always remains, if you use a certain section regularly, you always pay the minimum section fare, so the amount of fraud is the highest. .

■ Lapse within the loop This is a form as shown in ■ and @ in FIG. 1(3).

Currently, Japan's toll roads have multiple routes that are independent of each other.
Or, because they are connected in series, the routes do not go around, but for example, in a place where future route ■ and route ■ exist in parallel to each other, a bypass is formed between both routes. In some cases, the route will loop.

In such a case, for example, as shown in ■, even if a vehicle heading towards the loop from toll gate Y goes around the loop and exits to toll gate 2, it will only be able to charge the toll between y and z. .

Also, enter from 2 toll gates like O, go around the loop and go to Y
The same thing happens when you get off the tollgate.

As a method to prevent unauthorized traffic as described above, the conventional method (adopted in the new toll collection system) has been to check the time difference between entering at the toll gate entrance and exiting at the toll gate exit. If the evidence is weak, and the excuse is that the driver had a breakdown, an accident, or took a long break during the trip, it will not be possible to expose fraud.

There is also a method of recording the video signal of the vehicle or information such as the license plate on the ticket at the entrance of the tollgate, and playing it back at the exit of the tollgate for verification (JP-A-50-102711, JP-A-50-1999). 148995, etc.), but even if this method can detect the exchange of pass tickets, it cannot detect fraudulent use of pass tickets or circling within a loop, as shown in Figure 1. do not have.

Therefore, a fraud prevention device that is effective in all of the above-mentioned forms is desired.

By the way, looking at each of the above-mentioned forms of fraud, in each case, the entrance/exit route of the illegally passing vehicle to the main line of the toll road is different when entering and exiting.

In other words, an illegally passing vehicle should have entered the upper 9 lanes at the entrance toll gate and exited from the lower υ lane.

The present invention has been made in view of the above-mentioned circumstances, and is intended for use in multi-section toll roads where connecting roads with the main line up lane and down lane at each entrance and exit toll gate merge. means for capturing the usage route of the connecting road in an image and outputting it as image information; means for issuing a pass to passing vehicles recording entrance information necessary for toll calculation including time information; a storage means for storing; a means provided at the exit toll gate for capturing an image of the route used by passing vehicles on the connecting road and outputting it as image information; a means for retaining this image information; and a means for reading recorded information of the toll ticket. At the same time, the travel time is checked based on the time information and the current time information, and when the travel time exceeds a predetermined time, the entrance information that matches the ticket record information and the corresponding image information are transmitted to the storage means. It comprises a means for giving a command, a means for reproducing and displaying the entrance information and image information transmitted by the command, and the image information held in the image information holding means, and when the issued pass is issued, the The system records the entrance route of a passing vehicle to the main line and the exit route of a passing vehicle presenting the ticket, and when the time check is missed, these images can be played back to confirm the route used. A toll road fraud prevention device that detects fraud by checking the abnormally long travel time that occurs in the case of illegal traffic, and by checking the entry and exit routes of suspicious objects using images. The purpose is to provide

An embodiment of the present invention will be described below with reference to the drawings.

The method of the present invention tracks at the entrance/exit of a toll road toll gate whether a passing vehicle is heading toward the upper lane or the lower υ lane at the entrance toll gate, and further tracks whether the passing vehicle is heading toward the upper lane or the lower υ lane at the exit toll gate. Check whether the vehicle came from the up lane or the down 9 lane.

If the entrance and exit routes of passing vehicles are checked at the entrance/exit toll plaza as in this method, as shown in the entrance/exit check column in Figure 1, the number of detours for one round of traffic outside the toll gate,
It becomes possible to detect irregularities within the loop.

The structure of tollgates in Japan is as shown in Figure 2.
The entrance and exit of the toll booth are at the top.

In many cases, the connecting road to the down lane is the same halfway and is not separated, and vehicles entering from the toll gate entrance can also enter the up lane or down lane, and at the toll gate exit, the up lane Because the connecting lanes and the connecting roads from the down lanes merge, it is difficult to judge whether passing vehicles will enter the upper lane or down lane, or exit from the upper lane or down lane.

Similarly, F is installed in the booth of the Y tollgate, G is the office of the Y tollgate, and H is installed at a position where the television camera 24 covers the field of view B. K indicates the office of two toll plazas, and L indicates the other toll plaza.

Next, the operation of this device having the above configuration will be explained.

First, an example (3)-0 in FIG. 1, in which a vehicle circles a road, will be described. Now, suppose that a passing vehicle enters from the Y tollgate entrance. The collector presses the check button on the ticket processing machine 26 to check whether or not the vehicle is committing fraud. Then, a ticket issuance process is performed. (This is done without informing passersby. At this time, the card processing signal shown in FIG. 4a is outputted from the ticket processing machine 26.

The collector hands this ticket C to the person passing the vehicle. At the same time, the card processing signal a is given to the timer circuit 32, and the timer circuit 32 operates for <T1 time as shown in FIG. The image data is then sent to the image/data processing device 23 as shown in FIG. 4(d). At the same time, the information on the issued ticket C (date of issue, hour, minute, second, toll booth number, lane number, vehicle type) is sent to the ticket processor 26 as shown in Figure 4 via the data transmission device 31. The image is sent to the image/data processing device 23 at the center H as shown in Figure e. The image information of the vehicle and the data of the pass C are stored in the image/data processing device 23 in one block. Passing vehicles enter the down lane of the Y toll gate, go around the loop, enter the up lane, and reach the 2 toll gate. Both the main traffic forces were heading towards the tollgate from the lower lane of the second tollgate in the exit lane, but at this time,
The exit route of the vehicle is imaged by the television camera 24 and stored in the image storage device 25. At the toll booth in the exit lane, the collector receives the vehicle's ticket C from a passerby and passes it on to the ticket processing machine 27 in the booth.Then, the traffic processing machine 27 reads out the recorded information of the ticket C and calculates the toll. Calculation and time check.Since this vehicle went around the loop,
If the pre-set allowable travel time, for example, determined for each section of use, is exceeded, the appropriate time has been exceeded and the time difference check will fail, so in this case, an image/data information transmission command (g in Figure 5) is generated. Then, it is sent via the data processing device 33, and the image/data processing device 23
Image and data information of the vehicle will be provided in time. Specifically, the vehicle at the Y tollgate sends traffic ticket information, that is, issue date, hour, minute, and second, tollgate number, lane number, and vehicle type signal, and is stored in block units in advance in the image/data processing device. Compare with other images and data. The image/data of the vehicle that has been matched is sent to the image/rotor temporary storage device 37 and temporarily stored therein. On the other hand, when the ticket C is applied to the ticket processing machine 22, an output from the ticket processing machine 27 indicating card processing is sent to the timer circuit 3, as shown in FIG.
5 and activate it. By the action of the timer circuit 35, the image storage device (
The data of VTR) 25 is rewound as shown in the fifth diagram,
Furthermore, a reproduction signal (FIG. 5 t) is sent to the image temporary storage device 38. The collector brings the ticket C of the vehicle caught in the time difference check to office K, runs the ticket C on the ticket processing machine 36 installed in office K, and at this point, the ticket is processed as shown in Figure 5 f. The card processing output is output as shown in FIG. 5, and the image/data processing device 23 operates as shown in FIG. Also, as shown in FIG. 5m, the image storage device 25 is reproduced and the tollgate exit image information is transferred to the image reproduction device (n) 31 .

is shown in the image. Therefore, it can be confirmed from these that the vehicle entered from the down lane at the Y tollgate entrance and exited from the upper υ lane at the 2nd tollgate exit, indicating that the vehicle has gone around the loop.

In addition, not only in loops, but also in cases where passes are exchanged or used, there will always be inconsistencies in the entry and exit routes, and since this route can be confirmed, any irregularities can be checked.

In addition, since a check mark indicating that fraud has been detected is recorded on the ticket, for vehicles that do not pass the time difference check, the data processing device 33 gives permission to the image/data processing device 23 to delete the stored data of the vehicle. This signal is sent to erase the data.

Although a system has been described above that sends images and information data of all the toll gate entrances to the center H, the data of the toll gate entrances may be transmitted to the toll gate only when a check for an illegally passing vehicle occurs. . FIG. 6 shows the system configuration diagram.

That is, this system is a partial modification of the system G in FIG. 3, in which the image transmission device 22 and data transmission device 31 are replaced with image temporary storage devices 61 and 62. After receiving the picture number, the signal from the television camera is stored for a certain period of time T1. Further, the f-ta temporary storage device 62 has a function of temporarily storing toll ticket information (entrance toll gate number, lane number, date of issuance of the toll ticket, hour, minute, and second, and vehicle type) from the off-traffic processing machine 26. 63 is an image/data processing device that stores the image signal in the temporary image storage device 61 and the pass ticket information in the temporary data storage device 62 in units of blocks (both pieces of information are paired), and By receiving an image/data information transmission command from the data processing device 33 installed at office K, images and data are stored in the image/data temporary storage device 37 also installed at office K at the Z tollgate. It has the function of transmitting data information. Note that the image temporary storage device 61 and the data temporary storage device 62
The stored information is transmitted to the image/data processing device 63 at the same time as the falling signal from the timer circuit 32, and then
Such information shall be erased.

The above describes a method for directly exchanging data between tollgates, based on Figure 6. In the case of this method, the image storage device 6 of the office equipment is stored.

The functions other than the temporary data storage device 621 and the image/data processing device 63 are basically the same as those already described.

To summarize the effects of the two embodiments described above, first, as shown in FIG. 1, the entry of passing vehicles at the entrance and exit of the toll plaza.

Since it is possible to confirm the exit route (enter into the up and down lanes, or check whether to exit from the up and down lanes), it is possible to exchange the pass ticket by using the 1-pass roll, as shown in (3) in Figure 1.
If there are loops within the Luso as shown in Φ and @, it will be possible to point out inconsistencies in the route of travel.

Secondly, the evidence for the detection of fraud is an image signal.
Therefore, the strength of the evidence is high, and it becomes the final decisive factor in exposing fraud.

Thirdly, since only a small number of vehicles pass illegally, checking suspect vehicles using the 9-sampling method is an effective way to avoid unnecessarily increasing the storage capacity of the system. For example, it would be more effective to prevent fraud if only the trucks of large regular flights, where illegal traffic is rampant, were inspected.

As described in detail above, the present invention provides a multi-section toll road where connecting roads with the main line up lane and down lane at each entrance and exit toll gate merge, and which is provided at the entrance toll gate so that the connecting road for passing vehicles can be A means for capturing the route to be used in an image and outputting it as image information, a means for issuing a ticket to a passing vehicle recording entrance information necessary for fare calculation including time information, and a storage means for storing each of these pieces of information. , a means provided at the exit tollgate, means for capturing an image of the route used by passing vehicles on the connecting road and outputting it as image information; a means for retaining this image information; and a means for reading the recorded information of the pass and its time information. means for checking the travel time based on current time information, and when exceeding a predetermined time, giving the storage means an instruction to transmit entrance information that matches the ticket record information and the image information corresponding thereto; The apparatus comprises a means for reproducing and displaying the entrance information and image information thus transmitted, and the image information held in the image information holding means, and is transmitted to the main line of the passing vehicle that received the issued pass when the pass is issued. The entrance route and the exit route from the main line of the passing vehicle presenting the ticket are recorded, and when the time check is stopped, these images can be played back to confirm the route used, thereby preventing unauthorized passing. We have made it possible to check the abnormally long driving times that occur when vehicles are running, and to immediately check the entry and exit routes of suspicious vehicles using images, making it possible to efficiently catch illegal vehicles. It is possible to provide a toll road fraud prevention device that is extremely effective in preventing illegal traffic.
