Description

  The present invention relates to a technology for managing information on vehicles passing through the entrance and exit of a toll road.

  As a toll collection system based on ETC (registered trademark) on a toll road, there is a distance toll collection system that collects a toll determined according to the distance actually traveled from the entrance to the exit. As a traffic pattern in the distance charge collection method, there is a case where the entrance is configured by a toll gate ETC (registered trademark) and the exit is configured by a free flow ETC (registered trademark).

Unlike the toll gate ETC (registered trademark), the free flow ETC (registered trademark) has no gate. For this reason, a communication error occurs at the exit of the free flow ETC (registered trademark), and a vehicle that cannot collect charges cannot be stopped on the spot.
Therefore, it is necessary to take measures on the system side so that the appropriate toll can be charged at a later date for suspected vehicles that have had communication abnormalities at the exit due to some reason and illegal vehicles that intentionally illegally pass. Met.

  Patent Document 1 compares number information obtained by photographing a vehicle number plate at a toll gate ETC (registered trademark) at the entrance and number information obtained by photographing a vehicle number plate at a checkpoint. Are associated with each other.

Japanese Patent Laid-Open No. 2003-216989

However, the exit data obtained by communicating with the vehicle-mounted device at the exit of the toll road and the number information obtained by photographing the vehicle number plate at the exit are not associated with each other and stored. Therefore, in the technique described in Patent Document 1, it is not possible to associate the exit data with the entrance data obtained by communicating with the vehicle-mounted device at the entrance of the toll road. Therefore, an appropriate toll cannot be charged at a later date for a vehicle that has not paid a toll at the exit.
An object of the present invention is to make it possible to charge an appropriate toll for a vehicle that has not paid a toll at the exit.

A traffic information processing apparatus according to the present invention includes:
A storage device that acquires entrance data acquired from an onboard device mounted on a vehicle passing through an entrance of a toll road and exit data acquired from an onboard device mounted on a vehicle passing through the exit of the toll road A data acquisition unit stored in
A determination unit that associates the entrance data with the exit data by determining whether the information included in the entrance data and the exit data acquired by the data acquisition unit match;

  In this invention, it is linked | related with entrance data and exit data by determining whether the information contained in entrance data and exit data corresponds. Therefore, the entrance data corresponding to the exit data indicating that the toll has not been paid can be specified. Accordingly, it is possible to charge an appropriate toll.

Write to the information storage unit 133.

<This processing>
In this process, the determination unit 22 associates the entrance data with the exit data by determining whether the information included in the entrance data and the exit data acquired by the data acquisition unit 21 matches. Specifically, the determination unit 22 determines whether at least any one of the vehicle-mounted device ID, the vehicle number, the WCN, and the LID included in the entrance data and the exit data matches.
This process is executed at regular time intervals. In the first embodiment, it is assumed that this process is executed every hour.

This process will be described in detail with reference to FIG.
(Step S11: target exit data specifying process)
The reading unit 221 sequentially reads out the exit data newly acquired in the data acquisition process from the exit data storage unit 132 as target exit data.
In the first embodiment, this process is executed every hour. Therefore, as shown in FIG. 4, the reading unit 221 sequentially sets the exit data acquired from the vehicle-mounted device mounted on the vehicle that has passed the exit of the toll road for the last hour as the target exit data.

(Step S12: Target entrance data specifying process)
The reading unit 221 uses, as the exit reference time, the time when the vehicle on which the vehicle-mounted device that is the acquisition source of the target exit data is mounted passes through the exit among the entrance data stored in the entrance data storage unit 131. Then, as shown in FIG. 4, reading unit 221 is obtained from the vehicle-mounted device mounted on the vehicle that has passed through the entrance after the first time before the first reference time of the exit (24 hours in the first embodiment). The entered data is a candidate. Further, the reading unit 221 selects any of the entrance data acquired from the vehicle-mounted device mounted on the vehicle that has passed the entrance before the first time (24 hours in the first embodiment) before the exit reference time. Entrance data that is not linked to exit data is also added to the candidates.
However, the reading unit 221 selects, from candidates, entrance data that has passed a second time (3 days in the first embodiment) from the time when the vehicle equipped with the vehicle-mounted device from which the entrance data is acquired passes through the entrance. remove.

(Step S13: Matching process)
The abutting unit 222 reads out one piece of entrance data as target entrance data in order from the candidate entrance data. And the abutting part 222 performs entrance determination 1-4 about object exit data and object entrance data.
In the entrance determination 1, the matching unit 222 compares the vehicle-mounted device ID of the target exit data with the vehicle-mounted device ID of the target entrance data, and writes in the memory 12 whether or not they match.
Next, in the entrance determination 2, the abutting unit 222 compares the vehicle number of the target exit data with the vehicle number of the target entrance data and writes in the memory 12 whether or not they match.
Next, in the entrance determination 3, the matching unit 222 compares the WCN of the target exit data with the WCN of the target entrance data and writes in the memory 12 whether or not they match.
Next, in the entrance determination 4, the matching unit 222 compares the LID of the target exit data with the LID of the target entrance data and writes in the memory 12 whether or not they match.

(Step S14: linking process)
When there is matching entrance data in at least one of the entrance determinations 1 to 4, the associating unit 223 associates the matched entrance data with the target exit data.
Then, as shown in FIG. 5, the associating unit 223 writes the identifier of the entrance data associated with the entry identifier column of the association information storage unit 134 and writes it into the exit identifier column of the association information storage unit 134. Write the exit data identifier. In addition, the linking unit 223 matches which information among the vehicle-mounted device ID, the vehicle number, the WCN, and the LID in the entry information and exit data associated with the match information column of the linking information storage unit 134. Write.

On the other hand, the linking unit 223 determines that the target exit data is unknown when there is no matched entrance data in any of the entrance determinations 1 to 4.
Then, as shown in FIG. 5, the associating unit 223 writes an identifier indicating unknown in the entry identifier field of the associating information storage unit 134, and the exit is displayed in the exit identifier field of the associating information storage unit 134. Write the data identifier. In FIG. 5, “ZZZ” is an identifier indicating that it is unknown.

<Post-processing>
In the post-processing, the determination unit 22 extracts entrance data whose exit is unknown. The post-processing is executed after the main processing is executed. That is, in the first embodiment, the post-processing is executed every hour.

The post-processing will be described in detail with reference to FIG.
(Step S21: Target entrance data specifying process)
The reading unit 221 associates with the exit data after the second time (3 days in the first embodiment) has elapsed since the time when the vehicle equipped with the vehicle-mounted device from which the entrance data was acquired passes through the entrance. The entry data not yet read is read from the entry data storage unit 131.
In the first embodiment, post-processing is executed every hour. Therefore, as shown in FIG. 7, the reading unit 221 starts from the vehicle-mounted device mounted on the vehicle that has passed through the entrance of the toll road 1 hour before the time point X before the second time (3 days in the first embodiment). Out of the acquired entrance data, the entrance data not linked to the exit data is read from the entrance data storage unit 131.

(Step S22: Exit unknown process)
The associating unit 223 sets the exit data read in step S21 as unknown.
Then, as shown in FIG. 5, the linking unit 223 writes the identifier of the entrance data in the entry identifier column of the linking information storage unit 134 and is unknown in the exit identifier column of the linking information storage unit 134. Write an identifier indicating.

<Additional processing>
In the additional processing, the determination unit 22 associates the exit number information that matches at least part of the entry number information included in the entry data associated with the exit data, with the exit data. The additional processing is executed after the processing is executed. That is, in the first embodiment, the additional process is executed every hour.

The adding process will be described in detail with reference to FIG.
(Step S31: Target exit data specifying process)
The reading unit 221 reads out the target exit data from the exit data storage unit 132 using the exit data associated with the entrance data in the latest main processing in turn as the target exit data, and also reads the target exit data from the entrance data storage unit 131. Read the entry data associated with the data.
In the first embodiment, this process is executed every hour. Therefore, as illustrated in FIG. 9, the reading unit 221 includes exit data associated with entrance data among exit data acquired from a vehicle-mounted device mounted on a vehicle that has passed the exit of a toll road in the last hour. Are the target exit data in order.

(Step S32: target exit number specifying process)
The reading unit 221 uses the exit number information photographed in the same time zone as the passage time included in the target exit data as a candidate.
In the first embodiment, as shown in FIG. 9, the reading unit 221 uses the exit number information whose shooting time is the latest one hour as candidates.

(Step S33: Matching process)
The abutting unit 222 extracts exit number information satisfying the following three conditions (1) to (3) for the target exit data from the candidate exit number information.
(1) The shooting date / time is within the target time (± 5 seconds in the first embodiment) with reference to the travel date / time included in the target exit data read in step S31. (2) The toll gate number is the same as the toll gate number included in the target exit data read in step S31. (3) The exit number information is completely or partially coincident with the entrance number information included in the entrance data associated with the target exit data read out in step S31. Note that the degree of matching may be determined by the accuracy of character recognition or the like.

(Step S34: linking process)
The associating unit 223 associates the exit number information extracted in step S33 with the target exit data.
Then, as shown in FIG. 5, the associating unit 223 extracts the exit number information extracted in step S33 in the exit number information column of the record in which the identifier of the target exit data is stored in the associating information storage unit 134. Write.

<Search process>
In the search process, the search unit 23 searches for entry data and exit data satisfying various conditions from information stored in the entrance data storage unit 131, the exit data storage unit 132, and the association information storage unit 134.
For example, as illustrated in FIG. 10, the search unit 23 searches for entrance data and exit data on the condition of the ETC (registered trademark) discrimination result, whether or not there is a charge, whether or not to pass, whether or not the ICC processing is performed, . The ICC process is a process performed by extracting an ETC (registered trademark) card from the vehicle-mounted device. Whether or not the ICC process is performed is determined based on the lane type. By performing a search based on such a condition, the search unit 23 outputs exit data of a vehicle that has not paid a toll at the exit, such as a suspected vehicle that has failed in communication at the exit and an unauthorized vehicle that intentionally passes illegally. And the entry data associated with the exit data.
