The violator identification device 10 detects whether a vehicle A arriving at a tollbooth of a toll road has violated regulations. The violator identification device 10 identifies a violator who is a driver of the vehicle A when it is detected that the vehicle A has violated regulations. The violator identification device 10 transmits information on the identified violator to a terminal device 20 which is provided in a regulation organization.
The toll collection system 11 is a system that collects a toll from the vehicle A using the toll road. The vehicle A using the toll road travels in a lane connecting a ordinary road to the toll road in a tollbooth which is provided at an entrance or an exit of the toll road.
As illustrated in
The roadside device 12 is a device group that collects tolls according to model types of vehicles A arriving at the tollbooth. In this embodiment, the roadside device 12 is also used as a device group that is used for the violator identification device 10 to acquire various types of information for detecting violation of a vehicle A and identifying a violator.
The roadside device 12 includes a vehicle speed sensor 120, a weight sensor 121, a vehicle height detector 122, a vehicle length detector 123, a roadside radio communication device 124, and a roadside camera 125.
The vehicle speed sensor 120 is a sensor that measures the speed of a vehicle A arriving at the tollbooth. For example, the vehicle speed sensor 120 according to this embodiment includes a plurality of vehicle detectors 120A and 120B which are provided in an existing toll collection system 11 as illustrated in
The vehicle speed sensor 120 measures the speed of a vehicle A on the basis of a period of time until the vehicle detector 120B located downstream (the +X side in
In another embodiment, the vehicle speed sensor 120 may be a radar for speed measurement.
The weight sensor 121 is a sensor that measures the weight of a vehicle A arriving at the tollbooth. For example, the weight sensor 121 according to this embodiment is a tread board which is provided in the existing toll collection system 11 as illustrated in
In another embodiment, a sensor that measures the total weight of a vehicle A may be provided as the weight sensor 121.
The vehicle height detector 122 is a sensor that measures the height of a vehicle A arriving as the tollbooth. In this embodiment, the vehicle height detector 122 employs a vehicle height detector which is provided in the existing toll collection system 11.
The vehicle length detector 123 is a sensor that measures the length of a vehicle A arriving at the tollbooth. In this embodiment, the vehicle length detector 123 employs the vehicle length detector which is provided in the existing toll collection system 11.

Personal information D1 (
For example, as illustrated in
(Functional Configuration)
As illustrated in
The vehicle identification information acquiring unit 100 acquires vehicle identification information for identifying a vehicle A in which a violator rides from an image captured by the roadside camera 125.
The radio communication unit 101 acquires medium information stored in a medium X of the vehicle A via the roadside radio communication device 124.
The violation detecting unit 102 detects violation of a vehicle A on the basis of a measurement result including at least one of speed, weight, height, and length of the vehicle A measured by the sensors (the vehicle speed sensor 120, the weight sensor 121, the vehicle height detector 122, and the vehicle length detector 123).
The personal information acquiring unit 103 acquires personal information which is correlated with vehicle identification information from a database 13 which is provided in a system that provides services for vehicles A. More specifically, the personal information acquiring unit 103 acquires personal information from the database 13 as a response by transmitting an instruction for requesting the database 13 to provide personal information correlated with vehicle identification information.
The system that provides services for vehicles A is the toll collection system 11 in this embodiment. In another embodiment, the system may be a toll collection system that collects fees of a parking lot.
The output unit 104 outputs violation information in which an image captured by the roadside camera 125, the personal information acquired by the personal information acquiring unit 103, and the measurement result from the sensors are correlated to a terminal device 20 which is provided in a regulation organization. Accordingly, the regulation organization can impose a penalty on a violator on the basis of the violation information collected by the terminal device 20.
Regulation information indicating limit values of speed, weight, height, and length of the vehicle for each toll road is stored in advance in the storage medium 105. Violation information prepared by the output unit 104 or the like may be stored in the storage medium 105.
(Flow of Processes)
An example of a flow of processes through which the violator identification device 10 of the violator identification system 1 detects violation and identifies a violator will be described below with reference to
When a vehicle A arrives at the tollbooth (the vehicle detector 120A detects presence of a vehicle A), the vehicle identification information acquiring unit 100 acquires vehicle identification information of the vehicle A from an image captured by the roadside camera 125 (Step S10). In this embodiment, the vehicle identification information acquiring unit 100 reads number plate information of the vehicle A (a classification number and a vehicle number marked on the number plate) and acquires the read number plate information as the vehicle identification information by performing predetermined image processing on the image captured by the roadside camera 125.
Then, the violation detecting unit 102 determines whether the vehicle A has violated regulations on the basis of the measurement results measured by the vehicle speed sensor 120, the weight sensor 121, the vehicle height detector 122, and the vehicle length detector 123 (Step S11).
For example, when the speed of the vehicle A measured by the vehicle speed sensor 120 is greater than a limit value (a speed limit) for a speed indicated by regulation information stored in advance in the storage medium 105, the violation detecting unit 102 determines that the vehicle A has violated regulations (Step S11: YES). The violation detecting unit 102 performs the same determination for the weight, the height, and the length of the vehicle A. When the measurement result of at least one of the speed, the weight, the height, and the length is greater than the corresponding limit value, the violation detecting unit 102 determines that the vehicle A has violated regulations (Step S11: YES).
On the other hand, when none of the speed, the weight, the height, and the length of the vehicle A is not greater than the corresponding limit values, the violation detecting unit 102 determines that the vehicle A has not violated regulations (Step S11: NO).
When the measurement results are greater by a predetermined allowable value or more than the limit values in consideration of measurement errors of the sensors or the like, the violation detecting unit 102 may determine that the vehicle A has violated regulations. In this case, an arbitrary value is set as the allowable value for each sensor.
When the violation detecting unit 102 detects that the vehicle A has violated regulations (Step S11: YES), the personal information acquiring unit 103 acquires personal information from the database 13 of the toll collection system 11 (Step S12). At this time, the personal information acquiring unit 103 requests the database 13 to provide personal information correlated with the vehicle identification information (the number plate information) acquired in Step S10.
The output unit 104 prepares violation information D2 of the vehicle A (
As illustrated in
The vehicle identification information is the number plate information of the vehicle A identified in Step S10.
The violation details are information including the item (speed, weight, height, and length) of which the regulation is determined to be violated in Step S11, the limit value thereof, and the measurement result thereof. For example, as illustrated in
The personal information is personal information acquired from the database 13 in Step S12, and includes, for example, a “name,” an “address,” and a “payment means” of an owner of the vehicle A as illustrated in
The image is an image including the number plate of the vehicle A which is captured by the roadside camera 125.
The image may include a face of a driver. In this case, the image of the number plate and the face image of the driver may be a single image or separate images.
An image including the entire vehicle body of the vehicle A may be additionally included in the image.
The violator identification device 10 repeatedly performs the aforementioned processes when a vehicle A arrives at the tollbooth. Accordingly, the violator identification device 10 can automatically provide violation information including violation details and a number plate of the vehicle A (and an image of a violator) to the regulation organization when it is detected that the vehicle A has violated regulations.
In the example illustrated in

The CPU 901 reads a program from the auxiliary storage device 903, loads the read program in the main storage device 902, and performs the processes in accordance with the program. The CPU 901 secures a storage area which is used for various processes by the violator identification device 10 in the main storage device 902. The CPU 901 secures a storage area (the storage medium 105) storing data in process in the auxiliary storage device 903 in accordance with the program.
Examples of the auxiliary storage device 903 include a hard disk drive (HDD), a solid state drive (SDD), a magnetic disk, a magneto-optical disc, a compact disc-read only memory (CD-ROM), a digital versatile disc-read only memory (DVD-ROM), and a semiconductor memory. The auxiliary storage device 903 may be an internal medium which is directly connected to a bus of the computer 900 or may be an external medium which is connected to the computer 900 via the interface 904 or a communication line.
