Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a double charging prevention method in a toll collection system.
[0002]
[Prior art]
At present, ETC (Electronic Toll Collection: automatic toll collection system) for the purpose of automatic toll collection on toll roads is attracting attention as an early practical application in ITS (Intelligent Transport System). This ETC system collects tolls by performing data transmission by wireless communication between a roadside device having a wireless communication function installed at a toll booth and an onboard device having a wireless communication function mounted on a vehicle. This allows vehicles to pass through toll gates on toll roads non-stop and cashless.
[0003]
In such a toll collection system, a roadside device at a toll gate charges a predetermined toll fee based on information obtained by wireless communication with an onboard device of a vehicle entering the toll gate. For this reason, the vehicle-mounted device stores various information such as a vehicle number of the vehicle and an identification number (ID) unique to the vehicle-mounted device. These pieces of information are stored in the vehicle-mounted device itself or in an IC card inserted into the vehicle-mounted device, and are used as necessary. A roadside machine, particularly its antenna, is provided for each lane of the toll gate. This is to perform individual communication with the vehicle that has entered each lane.
[0004]
FIG. 3, FIG. 4, and FIG. 5 show configuration examples of toll gates in ETC.
[0005]
In the toll gate shown in FIG. 3, a plurality (two in the figure) of roadside machines 1 and 2 correspond to a plurality of (two in the figure) lanes 8 and 9 having the same traveling direction (lanes in the figure). Above). The lanes 8 and 9 are divided by islands 10, and lane changes beyond the islands 10 are disabled. The communication areas 1a and 2a of the roadside machines 1 and 2 are set so as not to overlap. When the vehicle 11 enters the corresponding lanes 8 and 9, the roadside devices 1 and 2 perform charging processing on the vehicle-mounted device (not shown) independently of the other roadside devices 2 and 1.
[0006]
In this way, each roadside machine 1 and 2 performs the charging process independently, so that the charging logic is simplified, and it is only necessary to add a roadside machine when adding a lane, so it is relatively easy to add a lane. it can.
[0007]
In addition, the toll gate shown in FIG. 3 has a start restriction device (not shown) for each lane so that a toll collection can be performed manually for a vehicle without an on-vehicle device, There is an unillustrated toll booth on the island 10.
[0008]
The toll gate shown in FIG. 4 is used in the free flow type ETC, there is no island, the lane is displayed as a white line 12, and the lane can be changed within the toll gate. There are also no start restriction devices or booths for tolls. At this toll gate, there is a gantry 13 that straddles a plurality of (two in the figure) lanes 8 and 9 having the same traveling direction, and a plurality (two in the figure) of roadside machines 1 and 2 are arranged in each lane 8 and 9. Correspondingly, they are arranged in the gantry 13. Further, the roadside machines 1 and 2 in two adjacent lanes 8 and 9 are set so that their communication areas 1a and 2a partially overlap. In this toll gate, each roadside machine 1 and 2 performs a billing process for an in-vehicle device (not shown) independently of the other roadside machines 2 and 1 when the vehicle 11 enters the corresponding lanes 8 and 9. .
[0009]
The toll gate shown in FIG. 5 differs from that shown in FIG. 4 only in that the roadside units 1 and 2 in the adjacent lanes 8 and 9 are set so that their communication areas 1a and 2a do not overlap. .
[0010]
One conventional double charging prevention method is that when a certain roadside device 1 communicates with an on-vehicle device and performs a charging process, the roadside device 1 records the ID of the charged on-vehicle device for a certain period of time. In the meantime, it is a method of not communicating with the vehicle-mounted device having the same ID.
[0011]
The time for recording the ID is generally set based on a short time during which the vehicle 11 passes through the communication areas 1a and 2a of the toll gate at a normal traveling speed.
[0012]
Another conventional double charging prevention method is that after a roadside device sets the no-response time of an on-vehicle device and a certain on-vehicle device communicates with the roadside device and performs a charging process, the on-vehicle device This is a method of not communicating with a roadside device for a certain period of time.
[0013]
The no-response time of the vehicle-mounted device is generally set based on a short time during which the vehicle 11 passes through the communication areas 1a and 2a of the toll gate at a normal traveling speed.
[0014]
[Problems to be solved by the invention]
The conventional double billing prevention method described above is effective in many cases.
[0015]
However, when a traffic jam or the like occurs at a toll booth, it has been found that there are situations that cannot be dealt with by the conventional double billing prevention method as described in (1) to (3) below.
[0016]
(1) For example, as shown in FIG. 3, after the vehicle 11 travels in the lane 8 and the charging process by the roadside machine 1 is completed, the vehicle 11 moves backward and re-enters the lane 9 due to traffic congestion or the like. It can be considered to enter the communication area 2 a of the roadside device 2.
[0017]
In this case, since the ID of the charged onboard device is not recorded in the roadside device 2, communication with the onboard device is started and the charging process is performed. This is a double charge.
[0018]
Further, in FIG. 3, in the case of a traffic jam, the no-response time of the vehicle-mounted device elapses, so that the roadside device 2 and the vehicle-mounted device start communication and double charging occurs. Such double billing can also occur in the case of FIGS.
[0019]
(2) Also, for example, as shown in FIG. 4, when the vehicle 11 travels on the road 14 where the communication areas of the two roadside devices 1 and 2 overlap, the traffic is When staying in one place due to traffic congestion or the like, it can be considered that the communication areas continue to exist on the road 14 where they overlap.
[0020]
In this case, the no-response time of the vehicle-mounted device elapses in the case of a traffic jam, and the ID of the charged vehicle-mounted device is not recorded in the roadside device 2, so the roadside device 2 and the vehicle-mounted device are immediately connected. Communication starts and double charging occurs.
[0021]
(3) Further, for example, as shown in FIG. 5, after the vehicle 11 travels in a certain lane 8 and the billing process by the roadside device 1 is completed, the vehicle 11 travels diagonally due to traffic congestion and other lanes. It is conceivable that the vehicle travels 9 and enters the communication area 2 a of another roadside device 2.
[0022]
In this case, since the ID of the on-vehicle device that has been charged is not recorded in the roadside device 2, communication with the on-vehicle device is started and double charging occurs.
[0023]
Further, in FIG. 5, in the case of a traffic jam, the no-response time of the vehicle-mounted device elapses, so that the roadside device 2 and the vehicle-mounted device start communication and double charging occurs. Such double charging can also occur in the case of FIG.
[0024]

Generally, a toll booth number is assigned to a toll booth, but if the toll booth number is given separately for various types of toll booths such as exit, entrance, up lane, down lane, etc. The toll number can be used as toll gate identification information. If the toll gate with the same number includes different types of toll gates for up lanes, down lanes, exits, entrances, etc., information indicating the toll gate number and toll gate type (hereinafter referred to as toll gate) To be used as toll gate identification information.
[0029]
According to a second invention, in the first invention, the toll gate identification information and the processing time transmitted by the on-vehicle device are recorded on an IC card inserted in the on-vehicle device, and the on-vehicle device is transmitted by the roadside device. The toll gate identification information and the processing time are recorded on the IC card.
[0030]
A third invention is characterized in that, in the first invention or the second invention, the predetermined time is changed according to a traffic jam situation.
[0031]
In this case, the predetermined time may be changed manually, or the predetermined time may be automatically changed based on a predetermined degree of traffic congestion and the predetermined time.
[0032]

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS.
[0036]
FIG. 1 is a diagram showing a configuration example of a toll collection system having a double charging prevention function according to an embodiment of the present invention. FIG. 2 is a diagram showing a processing flow of the roadside machine. 3 is a diagram showing a configuration example of a toll gate in ETC, FIG. 4 is a diagram showing a configuration example of a toll gate in free flow type ETC, and FIG. 5 is a diagram showing another configuration example of a toll gate in free flow type ETC. is there.
[0037]
<Configuration>
In FIG. 1, a plurality (two in the figure) of roadside machines 1 and 2 are installed at a toll gate of the toll collection system. These roadside machines 1 and 2 are installed in a toll gate having a plurality of lanes 8 and 9 having the same traveling direction, as illustrated in FIGS. The roadside machine 1 corresponds to the lane 8, and the roadside machine 2 corresponds to the lane 9. Each of the roadside devices 1 and 2 has a wireless communication unit 3 and an antenna 4.
[0038]
In each of the roadside devices 1 and 2, the wireless communication unit 3 performs wireless communication with the vehicle-mounted device 5 via the antenna 4, thereby charging the vehicle-mounted device 5 independently of the other roadside devices 1 and 2. In addition, double charging is prevented.
[0039]
The vehicle-mounted device 5 includes a wireless communication unit and an antenna (not shown) in order to perform wireless communication with the wireless communication unit 3 of each roadside device 1 and 2.
[0040]
Generally, in ETC (including free flow type ETC), the IC card 6 can be inserted into the vehicle-mounted device 5, and billing processing can be performed only when the IC card 6 is inserted into the vehicle-mounted device 5.
[0041]
Therefore, in this example, the traffic history information is recorded on the IC card 6. The traffic history information includes the toll gate identification information of the toll gate that has performed the billing process, the processing time of the billing process (the time at which the toll gate performed the billing process), the toll fee, and the like.
[0042]
In addition to the latest toll gate identification information and processing time, all past toll gate identification information and processing time may be recorded on the IC card 6 within the recordable range, or the latest one may be overwritten. Good. In this example, the latest toll gate identification information and processing time are overwritten and recorded. Here, the latest toll gate identification information and processing time are toll gate identification information and processing time in the previous billing process.
[0043]
The toll gate identification information may be anything that can identify the toll gate. In general, a number (tollgate number) is assigned to a toll booth, but if the toll booth number is given separately to various types of toll booths for exit, entrance, up lane, down lane, etc. The toll gate number can be used as toll gate identification information. If the toll gate with the same number includes different types of toll gates for up lanes, down lanes, exits, entrances, etc., information indicating the toll gate number and toll gate type (hereinafter referred to as toll gate) To be used as toll gate identification information.
[0044]
In this example, the toll booth number and the toll booth type are used in combination as toll booth identification information.
[0045]
Further, a management control device 7 is connected to each roadside machine 1, 2. This is provided for receiving and managing charging data from the roadside devices 1 and 2 after their charging processing is completed. A maintenance panel 7 a is provided in the management control device 7.
[0046]
Furthermore, the wireless communication unit 3 of each roadside device 1 and 2 has a memory 3a, and this memory 3a has a threshold value n (predetermined time) used when determining whether the vehicle-mounted device 5 is charged or not charged. ) Is recorded. The threshold value n is an arbitrary value corresponding to the degree of traffic jam, such as 5 to 10 minutes. In general, the threshold value n is set to be large if the degree of traffic congestion is high, and is set to be small if it is low.
[0047]
In this example, traffic congestion information is input from an appropriate device to the maintenance panel 7a of the management control device 7, and the threshold value n is automatically set based on a predetermined relationship between the degree of traffic congestion and the threshold value n. It can be changed. The threshold value n may be set or changed manually from the maintenance panel 7a.
[0048]
<Operation>
Next, with reference to FIG. 2, the billing process for toll collection and the double billing prevention operation will be described.
[0049]
First, when a vehicle equipped with the vehicle-mounted device 5 enters the communication area of any roadside device in the toll gate, wireless communication is started between the wireless communication unit 3 of the roadside device and the vehicle-mounted device 5 (see step S1). ).
[0050]
During the communication with the vehicle-mounted device 5, the wireless communication unit 3 transmits a request for reading traffic history information to the vehicle-mounted device 5. In response to this, the vehicle-mounted device 5 reads and transmits the toll gate number, the toll gate type and the processing time from the traffic history information recorded on the IC card 6, so that the wireless communication unit 3 receives them (step (See S2).
[0051]
The wireless communicator 3 uses the received toll number (hereinafter referred to as a receiving toll gate number), toll gate type (hereinafter referred to as a receiving toll gate type) and processing time (hereinafter referred to as a receiving processing time) as its own. The toll booth number to which the roadside machine belongs (hereinafter referred to as the own tollgate number), the tollgate type (hereinafter referred to as the own tollgate type), and the current time are collated (see step S3). Based on this verification, the wireless communication unit 3 determines whether the vehicle-mounted device 5 is unbilled or charged at the toll gate (see steps S4, S5, and S6).
[0052]
In step S4, it is checked whether or not the received tollgate number matches the own tollgate number.
[0053]
If the receiving toll gate number does not match the own toll gate number, it can be seen that the on-board device 5 of the communication partner has been charged at another toll booth and has not yet been charged at the own toll gate. From this, it is determined that the device is an uncharged vehicle-mounted device, and the billing process is continued (see step S9).
[0054]
If no traffic history information is recorded because the IC card 6 is not used or the like, there is no reception toll gate number, so that it naturally does not match the own toll gate number. Accordingly, the billing process is continued in this case as well.
[0055]
If the received tollgate number matches the own tollgate number, it cannot be determined whether the vehicle-mounted device 5 is unbilled or charged, and a further check is performed in the next step S5.
[0056]
In step S5, it is checked whether or not the receiving tollgate type matches the own tollgate type.
[0057]
If the receiving tollgate type does not match the own tollgate type, it is known that the type has been charged at another tollgate, and the tollgate has not yet been charged. It determines with it being an onboard equipment, and a billing process is continued (refer step S9).
[0058]
If the receiving tollgate type matches the own tollgate type, it cannot be determined whether the on-vehicle device 5 is uncharged or charged, and the flow proceeds to the next step S6 for further checking.
[0059]
In step S6, the threshold value n (predetermined time) recorded in the memory 3a is used to check whether the reception processing time is in the past before the predetermined time n from the current time or within the predetermined time n from the current time. By doing so, it is determined whether the on-board device 5 of the communication partner is uncharged or charged. In this example, the magnitude relation between the sum of the reception processing time and the predetermined time n and the current time is checked.
[0060]
In other words, if reception processing time + predetermined time n ≦ current time, since the reception processing time is in the past before the predetermined time n from the current time, the billing process is carried out at the toll gate long before regardless of traffic congestion. It can be considered that it has entered the toll gate separately. Therefore, in this case, it is determined that the on-board device 5 as the communication partner is not charged, and the charging process is continued (see step S9).
[0061]
If reception processing time + predetermined time n> current time, the reception processing time is a past time after the predetermined time n from the current time. For this reason, it can be regarded as having entered the toll gate again. Therefore, in this case, it is determined that the on-board device 5 as the communication partner has already been charged.
[0062]
If the vehicle-mounted device 5 is already charged, double charging will occur if the communication is continued and charging processing is continued (see step S7). Therefore, the wireless communication unit 3 interrupts the wireless communication without performing the billing process (see step S8).
[0063]
After the billing process is completed in step S9, the wireless communication unit 3 transmits the tollgate number, the own tollgate type, the billing process processing time, the toll fee, etc. as billing data to the in-vehicle device 5 and the IC card. 6 (see step S10), and the wireless communication with the vehicle-mounted device 5 is terminated (see step S11).
[0064]
As for the end of wireless communication, when the vehicle-mounted device 5 receives billing data (own tollgate number, own tollgate type, billing processing time, toll, etc.) from the roadside device, a billing result response indicating this is transmitted. Therefore, the wireless communication unit 3 terminates the wireless communication when receiving this billing result response.
[0065]
As described above, if the receiving tollgate identification information (in this example, the receiving tollgate number and the receiving tollgate type) does not match the own tollgate identification information (in this example, own tollgate number and own tollgate type), and receiving Even if the toll gate identification information matches the own toll gate identification information, if the reception processing time is in the past of the predetermined time n before the current time, it is determined that the vehicle-mounted device 5 is not charged, and the vehicle mounted The charging device 5 is charged, and the toll gate identification information (the toll gate number and the own toll gate type in this example) and the processing time are transmitted to the in-vehicle device 5 and recorded.
[0066]
On the other hand, the receiving toll gate identification information (in this example, the receiving toll gate number and the receiving toll gate type) matches the own toll gate identification information (in this example, the own toll gate number and the own toll gate type), and the reception processing time Is past in a predetermined time n after the current time, it is determined that the vehicle-mounted device 5 has been charged, and the vehicle-mounted device 5 is not charged.
[0067]
As a result, double charging, which is a problem in the prior art, can be prevented.
[0068]
<Specific example of the double charging prevention operation: Part 1>
Next, the double charging prevention operation at the toll booth illustrated in FIG. 3 will be described.
[0069]
In FIG. 3, when the vehicle 11 equipped with the vehicle-mounted device 5 passes through the lane 8 of the toll gate, the on-vehicle device 5 is charged by the roadside device 1 and the tollgate identification information (the tollgate number and the tollgate) of the roadside device 1 Type) and processing time are recorded in the vehicle-mounted device 5.
[0070]
It is assumed that the vehicle 11 moves backward and re-enters the lane 9 due to traffic congestion or the like after the billing process is completed.
[0071]
In this case, the roadside device 2 starts communication with the vehicle-mounted device 5 of the vehicle 11 and receives the tollgate identification information (tollgate number and tollgate type) and processing time from the vehicle-mounted device 5, Compare with location type and current time.
[0072]
At that time, the receiving tollgate identification information (receiving tollgate number and receiving tollgate type) is the same as the own tollgate identification information (own tollgate number and own tollgate type).
[0073]
Therefore, the roadside device 2 charges when the reception processing time is in the past of the predetermined time n before the current time, but in the present situation, the current time is close to the reception processing time, and the predetermined time n is calculated from the reception processing time. Since it does not exceed, charging processing is not performed. Thereby, the double charge by the roadside machine 1 and the roadside machine 2 which occurs in the case of a traffic jam or the like is prevented.
[0074]
<Specific example of double charging prevention operation: Part 2>
Next, the double charging prevention operation at the toll booth illustrated in FIG. 4 will be described.
[0075]
In FIG. 4, when a vehicle 11 travels on a road (between lanes 8 and 9) 14 where communication areas overlap at a toll booth and the vehicle-mounted device 5 communicates with the roadside device 1 first, the roadside device 1 charges. The toll gate identification information (toll gate number and toll gate type) of the roadside machine 1 and the processing time are recorded in the vehicle-mounted device 5.
[0076]
It is assumed that the vehicle 11 continues to exist on the road 14 where communication areas overlap due to traffic congestion after the billing process ends.
[0077]
In this case, when the no-response time of the vehicle-mounted device elapses due to traffic congestion or the like, the roadside device 2 starts communication with the vehicle-mounted device 5 of the vehicle 11, and the tollgate identification information (tollgate number and tollgate) Type) and processing time are received and verified with the own tollgate number, own tollgate type and current time.
[0078]
At that time, the receiving tollgate identification information (receiving tollgate number and receiving tollgate type) is the same as the own tollgate identification information (own tollgate number and own tollgate type).
[0079]
Therefore, the roadside device 2 charges when the reception processing time is in the past of the predetermined time n before the current time, but in the present situation, the current time is close to the reception processing time, and the predetermined time n is calculated from the reception processing time. Since it does not exceed, charging processing is not performed. Thereby, the double charge by the roadside machine 1 and the roadside machine 2 which occurs in the case of a traffic jam or the like is prevented.
[0080]
<Specific example of double charging prevention operation: Part 3>
Next, the double charging prevention operation at the toll booth illustrated in FIG. 5 will be described.
[0081]
In FIG. 5, when the vehicle 11 equipped with the vehicle-mounted device 5 passes through the lane 8 of the toll gate, the vehicle-mounted device 5 is charged by the roadside device 1, and the tollgate identification information (the tollgate number and the tollgate) of the roadside device 1 Type) and processing time are recorded in the vehicle-mounted device 5.
[0082]
Assume that the vehicle 11 travels diagonally and enters the adjacent lane 9 due to traffic congestion after the completion of the billing process.
[0083]
In this case, the roadside device 2 starts communication with the vehicle-mounted device 5 of the vehicle 11 and receives the tollgate identification information (tollgate number and tollgate type) and processing time from the vehicle-mounted device 5, Compare with location type and current time.
[0084]
At that time, the receiving tollgate identification information (receiving tollgate number and receiving tollgate type) is the same as the own tollgate identification information (own tollgate number and own tollgate type).
[0085]
Therefore, charging is performed when the reception processing time is in the past of the predetermined time n before the current time. However, in the current situation, the current time is close to the reception processing time and does not exceed the predetermined time n from the reception processing time. No billing process is performed. Thereby, the double charge by the roadside machine 1 and the roadside machine 2 which occurs in the case of a traffic jam or the like is prevented.
[0086]
In the above description, the toll gate number and the toll gate type are used together as the toll gate identification information. However, any information can be used as long as the toll gate can be identified. For example, when the toll gate number is assigned to various types of toll gates such as exit, entrance, up lane, down lane, etc., the toll gate number can be used as toll gate identification information.
[0087]
The above explanation is about ETC. Even if it is a toll collection system for reducing traffic congestion in urban areas known as ERP (Electonic Road Pricing), Since the toll gate has the same configuration as the toll gate of the free flow type ETC shown in FIGS. 4 and 5, the double charging prevention method of the toll collection system according to the present invention can be similarly applied.
[0088]
【The invention's effect】
As described above in detail with the embodiment of the invention, the first invention is mounted on a vehicle and a plurality of roadside devices installed corresponding to each of a plurality of lanes having the same traveling direction of the toll booth. In the toll collection system in which the plurality of roadside devices independently perform charging processing for the onboard device by wireless communication with the onboard device, each of the plurality of roadside devices communicates with the onboard device. ,
(1) Requesting the on-vehicle device to transmit traffic history information;
(2) Based on the received traffic history information, the identification information of the toll booth (hereinafter referred to as receiving toll gate identification information) and the time of the charging processing (hereinafter referred to as reception processing time) for which the latest charging processing was performed. The tollgate identification information (hereinafter referred to as own tollgate identification information) to which the roadside machine belongs and the current time are collated, the received tollgate identification information matches the own tollgate identification information, and the reception processing time is If it is in the past within a predetermined time from the current time, it is determined that the on-board unit is a charged on-board unit, and the reception toll gate identification information does not match the own toll gate identification information, and the reception processing If the time is in the past of a predetermined time before the current time, determining that the in-vehicle device is an unbilled on-vehicle device,
(4) The charging process is not performed for the on-vehicle device that has been charged, and the toll station identification information and the processing time are transmitted to the on-vehicle device and recorded by performing the charging process for the uncharged on-vehicle device. This is a double charging prevention method in the toll collection system.
[0089]
Therefore, according to the first invention, it is possible to prevent double charging when there is a traffic jam or the like at the toll gate.
[0090]
Further, in a second invention according to the first invention, the toll gate identification information and the processing time transmitted by the on-vehicle device are recorded in an IC card inserted in the on-vehicle device, and the on-vehicle device is the roadside device. The toll gate identification information to be transmitted and the processing time are recorded on the IC card.
[0091]
Therefore, according to the 2nd invention, double charge can be prevented with respect to the onboard equipment which has inserted the IC card.
[0092]
Further, the third invention is characterized in that, in the first invention or the second invention, the predetermined time is changed according to a traffic jam situation.
[0093]
Therefore, according to the third aspect of the invention, the double charging prevention effect is appropriate according to the degree of traffic congestion.
[0094]
In addition, the fourth invention relates to the first invention, the second invention, or the third invention, in which the vehicle traveling in one lane moves backward after the charge processing by the roadside device in the one lane is completed and re-enters another lane. It is characterized by preventing double charging by a roadside machine in the other lane that occurs when entering.
[0095]
