  In the above technology, the output beam is controlled or the installation state is adjusted so that the radio waves emitted from the ETC antenna reach only the range of the lane subject to measurement and billing. Is being considered. However, it is difficult to accurately control the radio wave irradiation range by such a method. Further, the radio waves emitted from the ETC antenna may be reflected by the ground or a vehicle and reach an area not intended by the installer. Therefore, it is difficult to completely limit the reach of the radio waves emitted from the ETC antenna to the target lane.

  Under such technical conditions and environmental conditions, it is difficult to accurately measure and charge only the vehicle traveling in the target lane heading in the predetermined traveling direction by using the ETC antenna. For example, if the radio wave irradiation area is set to be narrow so that the radio wave does not reach a vehicle traveling in the opposite lane, there is a problem that the target vehicle cannot be recognized because the radio wave does not reach the vehicle in the target lane. On the contrary, if the radio wave irradiation area is set to be wide in order to increase the recognition rate of the vehicle in the target lane, there is a problem that the possibility of erroneously recognizing the vehicle traveling in the opposite lane increases.

  The present invention has been made in view of the above problems. Therefore, an object of the present invention is to provide a vehicle passage information processing system for accurately recognizing a vehicle passing through a target lane.

  The above object is achieved by the following means.

  The vehicle passage information processing system is used in a lane having a first lane and a second lane that have different traveling directions, and includes a first acquisition unit, a second acquisition unit, a storage unit, a determination unit, and an output unit. Have. The first acquisition unit can acquire the unique information from the vehicle-mounted device that has entered the predetermined range through wireless communication, and acquires the unique information from at least the vehicle-mounted device installed in the vehicle traveling in the first lane. To do. The second acquisition unit can acquire the unique information from the vehicle-mounted device that has entered the predetermined range via wireless communication, and acquires the unique information from at least the vehicle-mounted device installed in the vehicle traveling in the second lane. To do. The storage unit sequentially stores the unique information acquired by the first acquisition unit and the second acquisition unit as vehicle passage information in the storage unit in association with the time when the specific information is acquired. The determination unit confirms the vehicle passage information accumulated in the storage unit and determines whether a plurality of vehicle passage information including the same unique information has been acquired within a predetermined period. When the determination unit determines that the vehicle passage information including the same unique information has been acquired by the determination unit within the predetermined period, the output unit outputs the vehicle passage information associated with the unique information and having an earlier time. The range in which the second acquisition unit can acquire the unique information is arranged on the downstream side in the traveling direction of the first lane than the range in which the first acquisition unit can acquire the unique information.

  According to the vehicle passage information processing system of the present invention, the unique information acquired from the vehicle-mounted device of the vehicle by the first and second acquisition units is acquired in the first and second lanes having different traveling directions. The information is sequentially accumulated in the storage unit as vehicle passage information in association with the time. The range in which the second acquisition unit can acquire the unique information is arranged on the downstream side in the traveling direction of the first lane than the range in which the first acquisition unit can acquire the unique information. The vehicle passage information processing system confirms the vehicle passage information accumulated in the storage unit, and when a plurality of vehicle passage information including the same unique information is acquired within a predetermined period, the time associated with the unique information. Outputs vehicle passing information that is early. Accordingly, the correct vehicle passage information that should be originally obtained by the first or second obtaining unit can be output, and thus the vehicle passing through the target lane can be accurately recognized. As a result, it is possible to accurately measure the number of vehicles passing through the target lane and to accurately charge the vehicle passing through the target lane.

  The auxiliary use ticket is suitably used, for example, for payment of a parking fee in a parking lot of a shopping center where many shops are opened. Hereinafter, a scene in which the supplementary ticket is suitably used will be specifically described. For example, in commercial facilities such as shopping centers, it is common practice to issue free parking tickets and discount tickets when a certain amount of money, such as several thousand yen, is used in the facility. When a user spends more than a certain amount of money at a certain store, the store issues a free parking ticket to the user, and the user uses the free parking ticket to exit from the parking lot. After that, the store pays to the operator of the parking lot an amount corresponding to the price of the parking ticket issued to the user.

  However, in a shopping center or the like, each store often brings in and uses a POS system for each store, and there is often no mechanism for integrating and summing the amount of money used by each user in each store. Therefore, parking tickets are often issued only when one store uses a certain amount or more. Further, for example, even if the parking charges are issued by manually summing the usage charges at a plurality of stores, it is necessary to charge the amount of money corresponding to the issued parking tickets according to the usage charges at each store. The burden on the center operator is heavy. Therefore, as in the present embodiment, each store electronically issues an auxiliary ticket according to the usage amount, and when a predetermined number is collected so that the user can use it as a parking ticket, the user can You can get parking tickets by adding up the amount spent at multiple stores. Further, since each store only has to pay the cost according to the issued auxiliary use ticket, it is possible to reduce the work burden on the operator of each store or shopping center.

  The attribute information is information used to judge the user's payment ability and reliability. As the attribute information, for example, occupation information, annual income information, usage record such as the number of times of past usage and usage amount, and user rank information according to these information are stored.

  The information described above as being stored in the storage unit 32 is stored in an external storage that can be connected from the server 30 via a network, and is configured to be accessed and acquired from the server 30 as needed. May be.

(Outline of processing)
FIG. 10 is a flowchart showing the procedure of vehicle passage information processing executed by the server. FIG. 11: is a figure which illustrates a mode that the information acquired earlier is output, when the same specific information is acquired several times within the predetermined period. The process shown in the flowchart of FIG. 10 is stored as a program in the storage unit 32 of the server 30, and is executed by the control unit 31 controlling each unit.

  As illustrated in FIG. 10, the server 30 sequentially receives the unique information acquired by the roadside devices 10a and 10b and the time when the unique information is acquired from the roadside devices 10a and 10b (step S101). The unique information and the time are associated and stored in the storage unit 32 as vehicle passage information (step S102). Specifically, the information as shown in FIG. 6 is accumulated in the storage unit 32.

  Subsequently, the server 30 confirms the vehicle passage information accumulated in the storage unit 32, and determines whether or not a plurality of the vehicle passage information including the same unique information is acquired within a predetermined period (step S103). ). The predetermined period is set to, for example, several seconds to several minutes based on the time required for the vehicle to pass between the roadside unit 10a and the roadside unit 10b. If it can be determined that a signal waiting or a traffic jam is occurring, the predetermined period may be set longer.

  If a plurality of vehicle passage information including the same unique information has not been acquired within the predetermined period (step S103: NO), the server 30 proceeds to the process of step S105.

  When a plurality of vehicle passage information including the same unique information is stored within the predetermined period (step S103: YES), the server 30 selects the vehicle passage information having the earlier acquired time as shown in FIG. (Step S104). In the example of FIG. 11, since two pieces of unique information indicating A101 have been acquired, the information acquired by the roadside device 10a having an earlier acquisition time is selected. Similarly, since two pieces of unique information indicating B101 have been acquired, the information acquired by the roadside device 10b having an earlier acquisition time is selected.

  The server 30 outputs the vehicle passage information selected in the process of step S104 and stored in the storage unit 32 for various purposes (step S105). The output vehicle passage information is, for example, a list for counting the number of vehicles passing through the target lane, or a service for billing a vehicle passing through the target lane for identifying a vehicle to be charged. It can be used as a list of unique information. For example, when the vehicle passage information is used as a list of unique information for specifying the charging target, the server 30 determines that the fee calculated based on a predetermined fee calculation method is used by the user identified by the unique information in the member database. You can request your wallet.

  According to the above-mentioned embodiment, the following effects are produced.

  The server 30 sequentially accumulates the unique information acquired in the roadside machines 10a and 10b respectively installed in the lanes A and B having different traveling directions in the storage unit 32 as vehicle passage information in association with the acquired time. The server 30 confirms the accumulated vehicle passage information, and when a plurality of vehicle passage information including the same unique information is acquired within a predetermined period, the vehicle passage information associated with the unique information is earlier in time. After selecting, the accumulated vehicle passage information is output. Here, the range 100b in which the roadside machine 10b can acquire the unique information is arranged downstream of the range 100a in which the roadside machine 10a can acquire the unique information in the traveling direction of the lane A. Thereby, for example, the unique information corresponding to the vehicle traveling in the lane A is first acquired by the roadside device 10a installed on the upstream side in the traveling direction of the lane A. After that, when the unique information of the vehicle is erroneously obtained by the roadside device 10b, the time at which the unique information is obtained by the roadside device 10b is later than the time at which the unique information is obtained by the roadside device 10a. Therefore, the server 30 can accurately recognize the vehicle passing through the target lane by selecting the information acquired earlier. As a result, it is possible to accurately measure the number of vehicles passing through the target lane and to accurately charge the vehicle passing through the target lane.

  The roadside machine 10b is installed on the downstream side in the traveling direction of the lane A with respect to the position where the roadside machine 10a is installed on the road. Accordingly, the range 100b in which the roadside machine 10b can acquire the unique information can be arranged easily and reliably downstream of the range 100a in which the roadside machine 10a can acquire the unique information in the traveling direction of the lane A. .

  Further, the range 100a in which the roadside device 10a can obtain the unique information includes the lane A when viewed from the traveling direction of the lane A, and the range 100b in which the roadside device 10b can obtain the unique information can be viewed from the traveling direction of the lane B. Including lane B. As a result, the roadside machine 10a can reliably acquire the unique information from at least the vehicle traveling in the lane A, and the roadside machine 10b can surely acquire the unique information from at least the vehicle traveling in the lane B.

  As the roadside device 10, a roadside device including an ETC antenna 14 that can communicate with the ETC vehicle-mounted device 40 is used. This makes it possible to utilize existing mechanisms efficiently and accurately recognize vehicles passing through the target lane without developing and installing dedicated equipment or developing new equipment and installing them on the vehicle. can do.

  Further, the unique information includes the vehicle-mounted device ID that is the identification information of the ETC vehicle-mounted device 40. As a result, the ETC vehicle-mounted device 40 installed in the vehicle can be recognized, so that passage of the vehicle can be easily and reliably recognized.

  Further, the unique information includes an ETC card number which is identification information of the ETC card inserted in the ETC vehicle-mounted device 40. As a result, the ETC card inserted into the ETC vehicle-mounted device 40 installed in the vehicle can be recognized, so that passage of the vehicle can be easily and reliably recognized.

  Moreover, at least one of the lane A and the lane B may be divided into a plurality of lanes. As a result, a vehicle passing through the target lane can be accurately recognized regardless of the width of the lane or the number of lanes.

  The present invention is not limited to the above-described embodiment, and various modifications and improvements can be made within the scope of the claims.

  For example, the process of the system 1 according to the above-described embodiment may include steps other than the steps in the above-described flowchart, or may not include some of the steps described above. Further, the order of steps is not limited to the above-described embodiment. Furthermore, each step may be combined with other steps and executed as one step, may be included and executed in another step, or may be divided into a plurality of steps and executed.

  In the above-described embodiment, the roadside machine 10a is installed on the lane A side and the roadside machine 10b is installed on the lane B side. However, the installation locations of the roadside machines 10a and 10b are not limited to this. For example, the roadside machine 10a may be installed on the lane B side and output a beam toward the lane A to acquire the unique information from a vehicle traveling in the lane A. Similarly, the roadside machine 10b may acquire the unique information from the lane A. The unique information may be acquired from a vehicle installed on the side and traveling in the lane B.

  In addition to the general road having the lane A and the lane B, the lane in the above-described embodiment is used in a vehicle facility such as a parking lot in which a vehicle entrance and an exit are arranged side by side in the same gate. It may be a road.

  In addition, in the above-described embodiment, an example in which the lane A (first lane) and the lane B (second lane) are lanes clearly separated by the center line as illustrated in FIG. 1, has been described. It is not limited to this. For example, in a lane that does not have a center line and is bidirectional, the system 1 according to the present invention can be applied assuming that the lane corresponds to both the lane A and the lane B. In this case, the vehicle traveling on the road has the unique information acquired by both of the roadside devices 10a and 10b regardless of the traveling direction, and by selecting the information having the earlier acquired time, the traveling direction of the passing vehicle can be determined. You can figure it out.

  Further, the means and method for performing various processes in each device of the system 1 according to the above-described embodiment can be realized by a dedicated hardware circuit or a programmed computer. The above program may be provided by a computer-readable recording medium such as a CD-ROM (Compact Disc Read Only Memory), or may be provided online via a network such as the Internet. In this case, the program recorded on the computer-readable recording medium is usually transferred and stored in a storage unit such as a hard disk. Further, the above program may be provided as independent application software, or may be incorporated into the software of each device of the system 1 as a function of each device.
