DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In this specification and the drawings, components having substantially the same functional configurations are designated by the same reference numerals, and duplicated explanations will be omitted.

[0021] In addition, in this specification and drawings, multiple components having substantially the same functional configuration may be distinguished by adding different numbers after the same reference symbol. However, if there is no particular need to distinguish between multiple components having substantially the same functional configuration, only the same reference symbol is used. Furthermore, similar components in different embodiments may be distinguished by adding different alphabets after the same reference symbol. However, if there is no particular need to distinguish between similar components in different embodiments, only the same reference symbol is used.

[0022] 1. DETAILED DESCRIPTION OF THE EMBODIMENTS The details of the embodiment of the present invention will now be described.

[0023] (1-1. Configuration of Information Processing System) First, a configuration example of an information processing system according to an embodiment of the present invention will be described. Fig. 1 is a diagram showing a functional configuration example of an information processing system according to an embodiment of the present invention. As shown in Fig. 1, the information processing system 1 includes an illegal traffic detection device 10, an RSU (Roadside Unit) 20, a probe processing device 30, an ETC 40, a toll gate server 50, and an employee terminal 60. Note that the vehicle M1 and the vehicle M2 are the same vehicle.

[0024] As shown in Fig. 1, the RSU 20 and the probe processing device 30 are connected, the ETC 40 and the toll gate server 50 are connected, the probe processing device 30 and the illegal passage detection device 10 are connected, and the toll gate server 50 and the illegal passage detection device 10 are connected. Furthermore, as shown in Fig. 1, the illegal passage detection device 10 and the staff terminal 60 are connected. The devices may be connected by wire or wirelessly.

[0025] (RSU20) The RSU 20 corresponds to a roadside wireless communication device and is also called an ITS (Intelligent Transport Systems) spot. The RSU 20 acquires information about the vehicle M1 (hereinafter, also referred to as "probe data") from the vehicle M1 by performing wireless communication with an ETC vehicle-mounted unit mounted on the vehicle M1.

[0026] Here, the probe data includes at least the passing time of the vehicle M1 for each preregistered position (kilometer post) and the ASL-ID (identification information of the ETC onboard unit) as an example of identification information of the vehicle M1. Note that the ASL-ID is merely an example of identification information of the vehicle M1, and other identification information of the vehicle M1 may be used instead of the ASL-ID. The RSU 20 transmits the acquired probe data to the probe processing device 30.

[0027] (Probe processing device 30) The probe processing device 30 receives the probe data transmitted by the RSU 20. Then, the probe processing device 30 stores the received probe data. The probe processing device 30 transmits the stored probe data to the illegal passage detection device 10. For example, the probe processing device 30 may transmit the stored probe data to the illegal passage detection device 10 at predetermined time intervals (e.g., every 5 minutes).

[0028] The probe processing device 30 may be realized by a computer. That is, the probe processing device 30 includes an arithmetic unit such as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit), and the functions of the probe processing device may be realized by the arithmetic unit expanding a program stored in a ROM (Read Only Memory) into a RAM and executing the program. At this time, a computer-readable recording medium on which the program is recorded may also be provided.

[0029] (ETC40) ETC 40 is configured to include an antenna of an opening / closing gate installed at a toll booth on a toll road (such as an expressway) and an ETC on-board unit mounted on vehicle M2. Here, the toll booth is installed at an entrance / exit connecting a general road and a toll road. The entrance / exit corresponds to an IC (interchange). Hereinafter, the interchange where vehicle M2 enters the toll road from a general road is also referred to as an entrance IC. Furthermore, the interchange where vehicle M2 exits the toll road onto the general road is also referred to as an exit IC.

[0030] The antenna of the gate acquires a WCN (Wireless Call Number) (identification information of the ETC vehicle unit) as an example of identification information of the vehicle M2 by performing wireless communication with the ETC vehicle unit. Note that the WCN is merely one example of identification information of the vehicle M2, and other identification information of the vehicle M2 may be used instead of the WCN. The ETC 40 transmits to the toll gate server 50 the acquired WCN of the vehicle M2, information regarding the entrance / exit through which the vehicle M2 passed, and the time when the vehicle M2 passed through the entrance / exit.

[0031] Here, the information regarding the entrance / exit includes information indicating an entrance IC or information indicating an exit IC. Hereinafter, information indicating an entrance IC will also be simply referred to as "entrance information." Furthermore, information indicating an exit IC will also be simply referred to as "exit information." Furthermore, the antenna of the opening / closing gate receives the toll calculated by the toll gate server 50, and performs a payment process for the received toll by wirelessly communicating with the ETC card installed in the vehicle M2.

[0032] (Tollgate server 50) The toll gate server 50 receives the WCN of the vehicle M2, information about the entrance / exit that the vehicle M2 passed through, and the passing time of the entrance / exit that the vehicle M2 passed through, all of which are transmitted by the ETC 40. The toll gate server 50 then stores the received WCN of the vehicle M2, information about the entrance / exit that the vehicle M2 passed through, and the passing time of the entrance / exit that the vehicle M2 passed through. The toll gate server 50 calculates the toll corresponding to the entrance information and exit information of the vehicle M2 as the toll to be paid by the vehicle M2, based on a correspondence table between the entrance information, exit information, and tolls prepared in advance.

[0033] The toll gate server 50 transmits the calculated toll payment of the vehicle M2 to the ETC 40. Furthermore, the toll gate server 50 transmits ETC data including the WCN of the vehicle M2, the entrance information through which the vehicle M2 passed, and the exit information through which the vehicle M2 passed, to the illegal passage detection device 10. As will be described in a modified example later, the ETC data transmitted from the toll gate server 50 to the illegal passage detection device 10 may include the toll payment of the vehicle M2, the entrance passing time at which the vehicle M2 passed the entrance, and the exit passing time at which the vehicle M2 passed the exit.

[0034] The toll gate server 50 may be realized by a computer. That is, the toll gate server 50 includes an arithmetic device such as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit), and the toll gate server 50 may realize its functions by a program stored in a ROM (Read Only Memory) being expanded into a RAM by the arithmetic device and executed. At this time, a computer-readable recording medium on which the program is recorded may also be provided.

[0035] (Illegal passage detection device 10) The illegal traffic detection device 10 is realized by a computer and can function as an example of an information processing device. With reference to Fig. 1, the illegal traffic detection device 10 includes an estimation unit 120, an identification unit 130, a determination unit 140, and an output unit 150. The illegal traffic detection device 10 stores correspondence information in which the WCN and ASL-ID of the same vehicle are previously associated with each other.

[0036] The estimation unit 120, the identification unit 130, the determination unit 140, and the output unit 150 each include a calculation device such as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit), and the functions of each unit can be realized by a program stored in a ROM (Read Only Memory) being loaded into a RAM and executed by the calculation device. At this time, a computer-readable recording medium on which the program is recorded can also be provided.

[0037] (Estimation part 120) The estimation unit 120 acquires the probe data received from the probe processing device 30. Then, the estimation unit 120 estimates entrance information (first entrance information) and exit information (first exit information) of the travel route of the vehicle M1 based on the probe data.

[0038] More specifically, the probe data includes the ASL-ID of the vehicle M1 and the passing time of the vehicle M1 at each position registered in advance. Therefore, the estimation unit 120 can estimate the entrance information and exit information of the travel route of the vehicle M1 by map mapping based on the passing time of the vehicle M1 at each position included in the probe data and a road map prepared in advance.

[0039] (Specific Section 130) The identification unit 130 acquires the ETC data received from the tollgate server 50. Then, the identification unit 130 identifies the entrance information (second entrance information) and exit information (second exit information) through which the vehicle M2 has passed, based on the ETC data.

[0040] More specifically, the ETC data includes the WCN of the vehicle M2, entrance information through which the vehicle M2 has passed, and exit information through which the vehicle M2 has passed. Thus, the identification unit 130 may identify the entrance information included in the ETC data as the entrance information through which the vehicle M2 has passed, and may identify the exit information included in the ETC data as the exit information through which the vehicle M2 has passed.

[0041] (Judgment unit 140) The determination unit 140 determines whether the vehicles M1 and M2 are the same vehicle based on the ASL-ID of the vehicle M1, the WCN of the vehicle M2, and pre-stored correspondence information. Here, it is assumed that the vehicles M1 and M2 are determined to be the same vehicle (hereinafter, simply referred to as "the same vehicle").

[0042] The determination unit 140 compares the entrance information estimated by the estimation unit 120 with the entrance information identified by the identification unit 130. Furthermore, the determination unit 140 compares the exit information estimated by the estimation unit 120 with the exit information identified by the identification unit 130. Then, the determination unit 140 determines whether or not at least one of the results of the comparison between the entrance information and the comparison between the exit information indicates a mismatch.

[0043] When at least one of the results of the comparison between the entrance information and the exit information shows a mismatch, it indicates that a vehicle may have illegally passed through the ETC lane (hereinafter, simply referred to as "illegal passage by a vehicle"). Therefore, this determination makes it possible to detect illegal passage by a vehicle with high accuracy.

[0044] (Output unit 150) When at least one of the results of the comparison between the entrance information and the exit information shows a mismatch, the output unit 150 outputs information indicating that there is a possibility of illegal passage by a vehicle (first information). This allows a predetermined person (such as an employee of the toll road management company) to understand that there is a possibility of illegal passage by a vehicle.

[0045] The output unit 150 transmits a message indicating that there is a possibility that a vehicle has illegally passed through the toll road to the staff terminal 60. This allows staff of the toll road management company to understand that there is a possibility that a vehicle has illegally passed through the toll road.

[0046] The output unit 150 may transmit information for identifying a vehicle that may have been illegally passed by the vehicle to a recording server (not shown). In this way, the information for identifying the vehicle recorded by the recording server (not shown) may be later referred to by an employee of the toll road management company, and the employee may later understand that illegal passage by a vehicle may have been committed. Here, the information for identifying the vehicle is not particularly limited. As an example, the information for identifying the vehicle may be the WCN of the vehicle.

[0047] Alternatively, the output unit 150 may output predetermined sound data to a speaker (not shown) to indicate that there is a possibility of illegal vehicle passage. This allows the staff and the driver of the vehicle to audibly understand that there is a possibility of illegal vehicle passage. For example, the predetermined sound data may be voice data such as "There is a possibility of illegal vehicle passage."

[0048] Alternatively, the output unit 150 may output predetermined display data to a display (not shown) (e.g., an electronic bulletin board, etc.) indicating that there is a possibility of illegal passage by a vehicle. This allows the staff and the driver of the vehicle to visually grasp that there is a possibility of illegal passage by a vehicle. For example, the predetermined display data may be display data such as "There is a possibility of illegal passage."

[0049] The output unit 150 may output a control signal to an opening and closing device (not shown) that is installed at the exit indicated by the exit information estimated by the estimation unit 120 or the exit information identified by the identification unit 130 in a closed state, as it is possible that a vehicle that may have illegally passed through the exit has been detected. This keeps the opening and closing bar closed, thereby preventing a vehicle that may have illegally passed through the exit from exiting.

[0050] (Staff terminal 60) The staff terminal 60 is a terminal used by staff of the toll road management company. The staff terminal 60 may receive information indicating that there may have been illegal passage by a vehicle from the illegal passage detection device 10. At this time, the staff terminal 60 outputs information indicating that there may have been illegal passage by a vehicle from a speaker or a display of the staff terminal 60, so that the staff of the toll road management company may know that there may have been illegal passage by a vehicle.

[0051] An example of the configuration of the information processing system 1 according to the embodiment of the present invention has been described above.

[0052] (1-2. Operation of Information Processing System) First, an operation example of the information processing system 1 according to the embodiment of the present invention will be described. Fig. 2 is a sequence diagram showing an operation example of the information processing system 1 according to the embodiment of the present invention.

[0053] 2, the probe processing device 30 transmits probe data to the illegal traffic detection device 10 (S11). Next, in the illegal traffic detection device 10, the estimation unit 120 acquires the probe data received from the probe processing device 30. Then, the estimation unit 120 estimates entrance information and exit information of the vehicle's travel route based on the probe data (S12). The estimation unit 120 transmits the estimated entrance information and exit information of the vehicle's travel route to the determination unit 140 (S13).

[0054] Meanwhile, the tollgate server 50 transmits ETC data including the WCN of the vehicle, the entrance information through which the vehicle passed, and the exit information through which the vehicle passed to the illegal passage detection device 10 (S14). In the illegal passage detection device 10, the identification unit 130 acquires the ETC data received from the tollgate server 50. Then, the identification unit 130 identifies the entrance information and exit information through which the vehicle passed based on the ETC data (S15). The identification unit 130 transmits the estimated entrance information and exit information through which the vehicle passed to the determination unit 140 (S16).

[0055] The determination unit 140 compares the entrance information estimated by the estimation unit 120 with the entrance information identified by the identification unit 130. Furthermore, the determination unit 140 compares the exit information estimated by the estimation unit 120 with the exit information identified by the identification unit 130. Then, the determination unit 140 determines whether or not at least one of the results of the comparison between the entrance information and the comparison between the exit information shows a mismatch, thereby determining whether or not illegal passage by a vehicle has occurred (S17).

[0056] Next, the determination unit 140 outputs the determination result to the output unit 150 (S18). If unauthorized passage by a vehicle has occurred, the output unit 150 notifies the staff terminal 60 that there is a possibility that unauthorized passage by a vehicle has occurred (S19). This allows the staff member to grasp that there is a possibility that unauthorized passage by a vehicle has occurred.

[0057] An example of the operation of the information processing system 1 according to the embodiment of the present invention has been described above.

[0058] (1-3. Effects) As described above, according to the information processing system 1 according to the embodiment of the present invention, it is determined whether or not at least one of the results of the comparison between the entrance information of the vehicle's travel route estimated based on the probe data and the entrance information passed by the vehicle identified based on the ETC data and the results of the comparison between the exit information of the vehicle's travel route estimated based on the probe data and the exit information passed by the vehicle identified based on the ETC data shows a mismatch. This makes it possible to detect illegal passage of a vehicle with a higher accuracy.

[0059] The effects achieved by the information processing system 1 according to the embodiment of the present invention have been described above.

[0060] (2. Hardware configuration example) Next, an example of the hardware configuration of the illegal passage detection device 10 according to the embodiment of the present invention will be described.

[0061] In the following, an example of the hardware configuration of the information processing device 900 will be described as an example of the hardware configuration of the illegal passage detection device 10 according to the embodiment of the present invention. Note that the hardware configuration example of the information processing device 900 described below is merely one example of the hardware configuration of the illegal passage detection device 10. Therefore, the hardware configuration of the illegal passage detection device 10 may be such that unnecessary components are deleted from the hardware configuration of the information processing device 900 described below, or new components are added. Note that the hardware configurations of the probe processing device 30 and the toll gate server 50 may also be realized in the same manner as the hardware configuration of the illegal passage detection device 10.

[0062] 3 is a diagram showing a hardware configuration of an information processing device 900 as an example of the illegal passage detection device 10 according to an embodiment of the present invention. The information processing device 900 includes a CPU (Central Processing Unit) 901, a ROM (Read Only Memory) 902, a RAM (Random Access Memory) 903, a host bus 904, a bridge 905, an external bus 906, an interface 907, an input device 908, an output device 909, a storage device 910, and a communication device 911.

[0063] The CPU 901 functions as an arithmetic processing device and control device, and controls the overall operation of the information processing device 900 in accordance with various programs. The CPU 901 may also be a microprocessor. The ROM 902 stores programs and arithmetic parameters used by the CPU 901. The RAM 903 temporarily stores programs used in the execution of the CPU 901 and parameters that change appropriately during the execution. These are connected to each other by a host bus 904 consisting of a CPU bus etc.

[0064] The host bus 904 is connected to an external bus 906, such as a PCI (Peripheral Component Interconnect / Interface) bus, via a bridge 905. It is not necessary to configure the host bus 904, bridge 905, and external bus 906 separately, and these functions may be implemented in a single bus.

[0065] The input device 908 is composed of input means such as a mouse, keyboard, touch panel, button, microphone, switch, and lever for the user to input information, and an input control circuit that generates an input signal based on the user's input and outputs it to the CPU 901. A user who operates the information processing device 900 can input various data to the information processing device 900 and instruct the information processing device 900 to perform processing operations by operating this input device 908.

[0066] The output device 909 includes, for example, a display device such as a CRT (Cathode Ray Tube) display device, a Liquid Crystal Display (LCD) device, an OLED (Organic Light Emitting Diode) device, or a lamp, and an audio output device such as a speaker.

[0067] The storage device 910 is a device for storing data. The storage device 910 may include a storage medium, a recording device for recording data in the storage medium, a reading device for reading data from the storage medium, and a deleting device for deleting data recorded in the storage medium. The storage device 910 is configured, for example, with an HDD (Hard Disk Drive). This storage device 910 drives a hard disk and stores programs executed by the CPU 901 and various data.

[0068] The communication unit 911 is, for example, a communication interface configured with a communication device for connecting to a network, etc. Also, the communication unit 911 may be compatible with either wireless communication or wired communication.

[0069] An example of the hardware configuration of the illegal passage detection device 10 according to the embodiment of the present invention has been described above.

[0070] (3. Summary) Although the preferred embodiment of the present invention has been described in detail above with reference to the accompanying drawings, the present invention is not limited to such an example. It is clear that a person having ordinary knowledge in the technical field to which the present invention pertains can conceive of various modified or altered examples within the scope of the technical ideas described in the claims, and it is understood that these also naturally belong to the technical scope of the present invention.

[0071] For example, the estimation unit 120 may estimate, based on the probe data, an entrance passing time (first entrance passing time) at which the vehicle passed an entrance (first entrance) indicated by entrance information (first entrance information) of the vehicle's travel route. Furthermore, the estimation unit 120 may estimate, based on the probe data, an exit passing time (first exit passing time) at which the vehicle passed an exit (first exit) indicated by exit information (first exit information) of the vehicle's travel route. For example, the entrance passing time and the exit passing time may be estimated by map matching.

[0072] Furthermore, the identification unit 130 may identify an entrance passing time (second entrance passing time) at which the vehicle passed through an entrance (second entrance) indicated by the entrance information (second entrance information) based on the ETC data. Furthermore, the identification unit 130 may identify an exit passing time (second exit passing time) at which the vehicle passed through an exit (second exit) indicated by the exit information (second exit information) based on the ETC data.

[0073] At this time, the determination unit 140 may determine whether or not a first condition is satisfied that the difference between the entrance passing time estimated by the estimation unit 120 and the entrance passing time identified by the identification unit 130 is greater than a first threshold value. Furthermore, the determination unit 140 may determine whether or not a second condition is satisfied that the difference between the exit passing time estimated by the estimation unit 120 and the exit passing time identified by the identification unit 130 is greater than a second threshold value.

[0074] The determination unit 140 may further determine whether or not at least one of the first condition and the second condition is satisfied when at least one of the results of the comparison between the entrance information and the comparison between the exit information shows a mismatch. With this configuration, it is possible to more accurately detect the possibility of illegal passage of a vehicle.

[0075] In addition, when the determination unit 140 determines that at least one of the first condition and the second condition is satisfied, the output unit 150 may output information indicating that there is a possibility that a vehicle has engaged in illegal passage.

[0076] Furthermore, when the determination unit 140 determines that at least one of the results of the comparison between the entrance information and the exit information indicates a mismatch, the determination unit 140 may add up the toll for the same vehicle according to the entrance information and the exit information identified by the identification unit 130. Then, the determination unit 140 may determine whether the accumulated amount is greater than a predetermined amount. This allows detection of vehicles that have accumulated illegal passages equivalent to a large amount of toll.

[0077] At this time, when the accumulated amount is greater than a predetermined amount, the output unit 150 may output information (second information) different from the possibility that illegal passage by a vehicle has occurred. For example, when the accumulated amount is greater than a predetermined amount, the output unit 150 may output the possibility that illegal passage by a vehicle has occurred cumulatively, the amount of illegal passage corresponding to a large amount of toll. Note that the possibility that illegal passage by a vehicle has occurred cumulatively, the amount of illegal passage corresponding to a large amount of toll, may be output by a method similar to that for outputting the possibility that illegal passage by a vehicle has occurred.
