Description

  The present invention relates to a traffic control device such as an automatic ticket gate installed at a railway station, for example.

  The automatic ticket gate described in the following Patent Document 1 was previously proposed by the present applicant. In this automatic ticket gate, a plurality of sensors are linearly arranged in the passing direction, and the interval between the sensors is set so that adjacent sensors can detect one person at the same time. A plurality of sensors including at least adjacent sensors are grouped, and a status corresponding to the sensor position is assigned to each group. Then, when all the sensors in one group are outputting detection signals, it is determined that the person is in the status of the group, and the position of the person is determined by tracking the status transition. Manage in real time. In this way, the position of the passerby can be reliably tracked by the sensor, and the number of passersby can be accurately counted.

Japanese Patent Laying-Open No. 2005-4285

  In the automatic ticket gate described above, the passage information recorded on the boarding medium (for example, a non-contact IC card) possessed by the passer is read by a reading means (for example, an antenna) to determine whether or not the pass is permitted. When the sensor detects that the vehicle has reached a predetermined position in the vicinity of the reading means, the determination information is associated with the passerby. In this case, if the person or the baggage can be correctly identified, the determination information does not have much.

  However, since it is very difficult to identify a person or a baggage with 100% accuracy, even in the automatic ticket gate disclosed in Patent Document 1, there is a rare case where the determination information has a surplus. For example, if two passers enter the automatic ticket gate next to each other, if the determination results of the two tickets entered are passable, two determination information is stored in the storage means. If both passers-by pass through the passage in contact, both are recognized as one person, so there is only one determination information associated with it, and one determination information is left in the storage means.

  In addition, in an automatic ticket gate that identifies adults with a reflective light sensor, the sensor does not receive reflected light for some reason (for example, posture or color of clothes) even though the passerby is an adult When the normal adult ticket is inserted, the determination information is stored in the storage means, but since the adult is not identified, even if the passer passes through the passage, it is erroneously determined that the baggage has passed, not an adult, The judgment information is not associated. Therefore, also in this case, the determination information remains in the storage means.

  In a state in which such determination information remains, it is impossible to accurately prevent the subsequent passage of the user who should not be allowed to pass. For example, a user who is judged NG because the ticket is invalid due to expiration or the non-contact IC card is not held for a sufficient time on the antenna, so the predetermined data is not written on the card and the processing is not completed. Even a user is permitted to pass due to the remaining judgment information. Users who have not been able to block traffic will be blocked due to abnormal ticket or card information when passing through the next ticket gate device, but in this case, an attendant will be required to handle the unfinished media at the counter. The burden on the staff increases, such as having to rewrite. In addition, there is a problem that the illegal boarding prevention effect expected by the strict entry / exit check is reduced. In particular, recently, with the spread of contactless IC cards, there is a concern that such problems will increase.

  The present invention solves the above-described problems, and the object of the present invention is to ensure that even if there is a surplus of judgment information, it is possible to reliably prevent traffic for users who should not be allowed to pass. It is to provide a control device.

  According to the present invention, in a traffic control device that controls opening and closing of a door based on a determination result for a recording medium possessed by a passerby and permits or prohibits passage, a reading unit that reads traffic information recorded on the recording medium, A first determination unit that determines whether or not to allow traffic based on the traffic information read by the reading unit; a storage unit that stores the traffic information related to the determination by the first determination unit as determination information in the reading order of the reading unit; Passage management means for detecting passersby and managing the pass position for each passer, and storage means when it is determined by this passage management means that the passer has reached a predetermined position in the vicinity of the reading means The association means for associating the decision information with the passers in order from the decision information with the earliest reading order among the decision information stored in the information, and the passage determination result of the first decision means pass If yes, is there any preceding determination information stored in the storage means that is determined to be passable by the first determination means and there is a surplus of determination information that is not associated by the association means A second determination unit that determines whether or not there is a determination information surplus when the second determination unit determines that there is a surplus of determination information.

  Here, regarding the first determination unit, “determining whether or not to allow traffic based on the traffic information read by the reading unit” means that the traffic information read from the recording medium itself is NG (for example, expired, out of section, etc. ), The information read from the recording medium is OK, but writing to the recording medium (for example, recording of the entrance bit) could not be performed normally, so it is determined that the passage is impossible. Including cases.

  In the present invention, when the determination result of whether to pass is impassable, if there is a surplus of determination information that is not associated with the passer-by, this surplus is deleted, and therefore an invalid boarding medium is possessed. A user who has a boarding medium that has not yet been processed is not allowed to pass because there is not enough judgment information. Therefore, even if there is a remainder of the determination information, it is possible to reliably prevent the passage of users who should not be allowed to pass. As a result, it is possible to reduce the burden on the attendant by avoiding passage prevention when passing through the next ticket gate apparatus, and to enhance the illegal boarding prevention effect by strict entrance / exit check.

  In a preferred embodiment of the present invention, when the first determination means determines that the passage is impossible and the second determination means determines that there is a remainder of the determination information, the recording medium that is determined not to pass is determined. After determining whether or not the previous recording medium is allowed to pass, there is further provided third determination means for determining whether or not the association by the association means is performed. When it is determined by the third determination means that the association is performed, all the determination information remainders are deleted by the deletion means, and no association is performed by the third determination means. Is determined, the remaining determination information remainder is erased by the erasing means, leaving at least one remainder of the determination information.

  For example, there are two people in the vicinity of the reading unit, the determination result of the recording medium is OK for the front user, the association is incomplete, and the determination result of the recording medium of the rear user is NG. In such a case, if all the remaining determination information is deleted, the determination information of the user in front is also deleted, so that the user in front is not allowed to pass without being associated. Therefore, as described above, by leaving at least one remainder of the determination information and deleting the remaining remainder of the determination information, it is possible to solve the problem that the user in front cannot pass.

  According to the present invention, it is possible to provide a highly reliable traffic control device that can reliably block traffic for a user who should not be permitted to travel.

A gate door provided on the side, 54 is an antenna for communicating with a non-contact IC card (not shown) used in the automatic ticket gate device 50, 55 is a normal boarding with the non-contact IC card read by the antenna 54 A lamp display unit for displaying whether or not the medium is used, 56 is a message display unit for displaying various messages such as passage permission and prohibition for passengers, 57 is a side plate provided on the side of the main body 51, and 58 is A child / student display lamp provided on the upper surface of the side plate 57, 59 a cover for covering a sensor (described later) provided in the side plate 57, 60 a pass / fail display unit provided on the front of the main body 51, and 61 1 A passage formed by the automatic gate apparatus 50.

  The automatic ticket gate 50 as described above is installed, for example, at a railway station, and when a passenger holds the non-contact IC card over the antenna 54, the data of the non-contact IC card read by the antenna 54 is stored inside the main body 51. The control unit is sent to the control unit, and the control unit determines whether the boarding medium is appropriate and controls the opening and closing of the gate doors 52 and 53 to permit or prohibit the passage. Here, a contactless automatic ticket gate using a contactless IC card as a boarding medium is taken as an example, but the present invention is a contact type automatic ticket gate using a magnetic card, a magnetic card and a contactless IC.

Reference numerals 33, 34, and 42 denote door part child detection sensors provided on the bill collection side of the automatic ticket gate 50, and the door part child detection sensors 33 and 34 are located above the gate door 53. It is also used as an entry / exit detection sensor. The door child detection sensor 42 is disposed at a lower position of the gate door 53. Each of these sensors 31 to 34, 41, and 42 is composed of a transmissive optical sensor, like the sensors 1 to 20. 4 indicates the optical axes of the sensors 31 to 34, and L3 indicates the optical axes of the sensors 41 and 42.

  In FIG. 2, the sensors 1 to 20 are installed at a height of about 90 cm from the installation surface (floor surface) of the automatic ticket gate device 50, and the sensors 31 to 34 are installed at a height of about 70 cm from the installation surface. The sensors 41 and 42 are installed at a height of about 40 cm from the installation surface. However, these are only examples, and the installation height of each sensor may be set to an optimum value as necessary.

  FIG. 5 is a block diagram showing the electrical configuration of the automatic ticket gate 50. Reference numeral 71 denotes a CPU as a control unit for controlling the operation of the automatic ticket gate device 50, and 72 denotes a storage unit including a memory. The storage unit 72 is provided with a determination information queue (Queue) 73a in which determination information described later is temporarily stored, and a link table 73b for associating the determination information with a passerby. In addition, the storage unit 72 temporarily stores traffic information read from the boarding medium, a region for storing operation programs and control parameters for the CPU 71, and a region for storing operation data for the automatic ticket gate device 50. Etc. are provided (not shown). The CPU 71 constitutes an embodiment of the first determination means, the second determination means, the third determination means, the association means, and the erasure means in the present invention. Moreover, the memory | storage part 72 comprises one Embodiment of the memory | storage means in this invention.

Read without contact. The human detection unit 78, together with the CPU 71 and the storage unit 72, constitutes one embodiment of the traffic management means in the present invention. The antenna 54 constitutes one embodiment of the reading means in the present invention, and the non-contact medium 81 constitutes one embodiment of the recording medium in the present invention.

  FIG. 6 is an example of a determination information format representing determination items in the automatic ticket gate 50. As judgment items, there are a boarding ticket ID, a judgment result, a processing state, a ticket insertion direction, a child insertion, and an adult ticket / child ticket. The ticket ID is an identification number assigned to each boarding medium. The determination result includes determination OK, determination NG, and pre-determination. In the case of an effective boarding medium, the determination result is “OK”, and in the case of an invalid boarding medium, the determination result is “NG”. The processing status includes processing, processing incomplete, and processing completion. After the determination is made based on the information read from the boarding medium, the processing is completed only after predetermined information (for example, an entrance bit and a boarding station code) is normally written on the boarding medium. The passage is permitted when the determination result is OK and the processing state is completed. Even if the determination result is OK, if the writing fails, the processing is not completed and passage is prohibited. The ticket insertion direction is determination information indicating whether the boarding medium is inserted from the ticket gate side or the ticket collection side. Child insertion is determination information indicating whether or not a ticket has been inserted, and is obtained from detection results of adult / child sensors 21 and 22 (FIG. 2). The adult ticket / child ticket is determination information indicating whether the inserted ticket is an adult ticket or a child ticket.

  FIG. 7 is a diagram schematically illustrating the determination information queue 73 a in the storage unit 72. The determination information queue 73a is a first-in first-out (FIFO) buffer, in which determination information with a determination result of “OK”, that is, determination information that has been processed, that is, determination information that has been determined to be passable is sequentially stored, and has the fastest reading order. It is extracted in order from the (old) information. In the example of FIG. 7, the determination information 1, the determination information 2, and the determination information 3 are stored in this order, and the determination information 1, the determination information 2, and the determination information 3 are extracted in this order.

  FIG. 8 is a diagram schematically showing the link table 73 b in the storage unit 72. In the link table 73b, determination information taken out from the determination information queue 73a in the order of reading is recorded in association with passengers. This association is performed every time a passenger reaches a no-tag detection position described later. Each passenger is assigned a passenger ID, and this passenger ID is assigned when the passenger enters the aisle as will be described later. Further, status information for each passenger is also recorded in the link table 73b. The status information is information for tracking the position of a person passing through the automatic ticket gate 50 and managing the passing position for each passerby in real time. The status information is described in detail in the above-mentioned Patent Document 1, but will be described below.

  9A and 9B are diagrams for explaining statuses and transitions thereof. The status is position information that groups a plurality of sensors and assigns each group corresponding to the sensor position. For example, as shown in FIG. 9A (a), the sensor 1 and the sensor 31 provided at intervals in the vertical direction constitute one group, and the status ST1 is assigned to the group. Further, as shown in FIG. 9A (b), adjacent sensors 1 and 2 and sensor 31 constitute one group, and status ST2 is assigned to the group. Further, as shown in FIG. 9A (c), adjacent sensors 2 and 3 and sensor 32 constitute one group, and status ST3 is assigned to the group. Similarly, as shown in FIG. 9A (d), adjacent sensors 3 and 4 and sensor 32 constitute one group, and status ST4 is assigned to the group.

  The subsequent statuses ST5 to ST17 are assigned as shown in FIGS. 9A (e) to (f) and FIG. 9B (g). That is, two adjacent sensors constitute one group, and statuses ST5, ST6,..., ST17 are sequentially assigned to each group. In addition, statuses ST18 to ST21 are assigned in the same manner as statuses ST4 to ST1.

  The CPU 71 monitors the detection signals from the sensors 1 to 20 and the sensors 31 to 34, and when all of the plurality of sensors in one group are outputting detection signals, that is, the light shielding of the sensors in one group. When the AND condition of the state is satisfied, it is determined that a person is located in the status of the group. In the following, it is assumed that only two adjacent sensors are shielded from light by one person.

  Considering the case where a passenger enters from the ticket gate side of the automatic ticket gate 50, since the sensors 1 and 31 at the entrance are simultaneously shielded at the same time, the CPU 71 at this point indicates that the current position of the human is FIG. 9A. It is determined that the status ST1 is (a). When the passenger travels along the passage 61, the sensor 2 is in a light-shielded state next. However, as described above, the distance between the sensor 1 and the sensor 2 is smaller than the front and rear width of the human torso, so The sensors 1, 2 and 31 are simultaneously shielded from light, and a detection signal is output from each sensor. Therefore, the CPU 71 determines that the current position of the person is the status ST2 in FIG. 9A (b).

  When the passenger further proceeds through the passage 61, the sensors 3 and 32 are next in a light-shielded state. However, since the distance between the sensor 2 and the sensor 3 is smaller than the front-rear width of the human torso, the sensor 2 maintains the light-shielded state. Thus, the sensors 2, 3 and 32 are simultaneously shielded from light, and detection signals are output from the sensors. Therefore, the CPU 71 determines that the current position of the person is the status ST3 in FIG. 9A (c). Similarly, when the passenger further proceeds through the passage 61, the sensors 3, 4 and 32 are simultaneously shielded from light, and the CPU 71 determines that the current position of the person is the status ST4 in FIG. 9A (d). When the passenger further proceeds through the passage 61, the sensors 4 and 5 are simultaneously shielded from light, and the CPU 71 determines that the current position of the person is the status ST5 in FIG. 9A (e).

  Similarly, as the passenger advances along the passage 61, the status changes to ST6, ST7,..., ST17 (FIG. 9A (f), FIG. 9B (g)). When the passenger approaches the vicinity of the exit, the three sensors (17, 18, 33, etc.) including the horizontal sensor and the vertical sensor are simultaneously shielded from light as shown in FIGS. 9B (h) to (j). Thus, the status transits to ST18, ST19, ST20. Finally, when the passenger reaches the exit, the upper and lower sensors 20, 34 are simultaneously shielded from light as shown in FIG. 9B (k), and the status is determined to be ST21. Thereafter, when the passenger leaves the exit, the sensors 20 and 34 are in a light-transmitting state, and the CPU 71 determines that the passenger has left the automatic ticket gate 50.

  In the above process, the CPU 71 assigns the above-described passenger ID to the passenger who has entered the automatic ticket gate 50 when the status ST1 is determined. Then, the assigned passenger ID is recorded in the link table 73b (FIG. 8). Then, CPU71 manages the position of the passenger of the ID by status information. That is, since the detection outputs of the sensors 1 to 20 sequentially change between the sensors as the traffic passes, the CPU 71 tracks the transition and updates the status information to accurately manage the position of the passenger in real time. be able to. In addition, when a hand or umbrella having a width smaller than that of a human torso is passed forward and passed, even if one sensor happens to detect it, it is determined that it has detected a human being. In addition, false detection can be prevented.

  Next, the determination process in the automatic ticket gate 50 will be described. 10 to 14 are schematic diagrams for explaining the principle of the determination process. In these figures, the same parts as those in FIG. The “no-tag detection position” is a reference position for determining whether or not the passenger has passed the non-contact medium 81 without holding the antenna 54, and is set to a predetermined position near the antenna 54. The tagless detection position is also a reference position that determines the timing for associating (linking) the person with the determination information.

  Now, in FIG. 10, when the determination is made by reading the traffic information from the boarding medium (non-contact IC card) possessed by the passenger P1, the ticket ID is assigned to the boarding medium as described above, and the judgment result is If the vehicle is allowed to pass (determination OK and processing is completed), the determination information J1 is stored in the determination information queue 73a. At this time, since the passenger P1 has not yet reached the no-tag detection position, the link between the passenger and the determination information is not completed. When the passenger P1 reaches the no-tag detection position, the determination information J1 which is the determination information stored in the determination information queue 73a and is the earliest in reading order is taken out from the determination information queue 73a, and the passenger P1 and the determination information J1 are linked. And recorded in the link table 73b.

  Next, when the passenger P1 enters the automatic ticket gate 50 after the passenger P1 whose link has been completed travels through the passage as shown in FIG. 11, the same processing as the passenger P1 is performed on the passenger P2. That is, when the determination is performed by reading the traffic information from the boarding medium of the passenger P2, the ticket ID is assigned to the boarding medium, and if the determination result is passable, the determination information J2 is stored in the determination information queue 73a. Is done. At this time, since the previous determination information J1 has already been extracted and does not exist, the determination information J2 is the determination information with the earliest reading order. When the passenger P2 reaches the no-tag detection position, the determination information J2 is taken out from the determination information queue 73a, and the passenger P2 and the determination information J2 are linked and recorded in the link table 73b.

  Next, when the passenger P3 enters the automatic ticket gate 50 after the passengers P1 and P2 whose links have been completed proceed as shown in FIG. 12, the same processing as the passengers P1 and P2 is performed on the passenger P3. Is done. That is, when the determination is made by reading the passage information from the passenger P3's boarding medium, the boarding ticket ID is assigned to the boarding medium, and if the judgment result is passable, the judgment information J3 is stored in the judgment information queue 73a. Is done. At this time, since the previous determination information J1 and J2 have already been extracted and do not exist, the determination information J3 is the determination information with the earliest reading order. When the passenger P3 reaches the no-tag detection position, the determination information J3 is taken out from the determination information queue 73a, and the passenger P3 and the determination information J3 are linked and recorded in the link table 73b.

  The above is a processing operation in a normal state in which there is not much judgment information, but as described above, when two passengers pass in contact or when a person is mistakenly detected as a luggage In this case, a determination information remainder is generated in the determination information queue 73a. If there is a remainder of the determination information, even if a passenger who should not be allowed to pass without taking the measures as in the present invention, the pass becomes possible. This will be described with reference to the example of FIG.

  As shown in FIG. 13, it is assumed that after the passengers P1 and P2 who have completed the link travel through the passage, the determination result of the subsequent passenger P3 with respect to the boarding medium is impassable (determination NG or incomplete processing). In this case, if there is not enough judgment information, the gate door 53 is closed after the passengers P1 and P2 exit the passage, and the passenger P3 is prohibited from passing, but in the example of FIG. Since there are remaining judgment information Jx and Jy, the gate door 53 remains open even after the passengers P1 and P2 exit the passage, and the passenger P3 can pass the automatic ticket gate 50 illegally. In addition, although the case where the determination information remainder is two was shown here, the case where there is one determination information remainder or three or more is the same.

  Therefore, in the present invention, as shown in FIG. 14, when the determination result of the passenger P3 with respect to the boarding medium is impassable, the determination information remainders Jx and Jy are deleted. In this way, since there is no remaining determination information, the passenger P3 who has a boarding medium whose determination result is not allowed to pass is blocked by the gate door 53 being closed after the passengers P1 and P2 exit the passage.

  FIG. 15 is a flowchart showing a detailed procedure of the determination process. This procedure is executed by the CPU 71 (FIG. 5) according to the determination processing program. In step S1, it is determined whether or not a passenger has entered based on the sensor output of the human detection unit 78. If there is an entry (step S1: YES), the process proceeds to step S2 and the boarding medium (non-contact IC card). Is received based on a signal from the antenna control unit 79. When the boarding medium is held over the antenna 54 and reception is detected (step S2: YES), the passage information recorded on the boarding medium is read to determine whether or not the board is allowed to pass (step S3). Further, when it is detected based on the sensor output of the human detection unit 78 (step S4: YES) that the passenger has reached the no-tag detection position without detecting the boarding medium (step S2: NO), the following will be described. The process proceeds to step S9.

  If the determination in step S3 is allowed to pass, the determination information is stored in the determination information queue 73a (step S5), and the process proceeds to step S8. On the other hand, if the determination in step S3 is not possible, the process proceeds to step S6 to check whether or not there is a remaining determination information in the determination information queue 73a. As a result, if there is no remainder of the determination information (step S6: NO), the process proceeds to step S8. If there is a remainder of the determination information (step S6: YES), all of the remainder of the determination information is cleared (erased) (step S7). Thereafter, the process proceeds to step S8. Steps S6 and S7 are processing steps that characterize the present invention.

  In step S8, it is determined based on the sensor output of the human detection unit 78 whether or not the passenger has reached the no-tag detection position. When the passenger reaches the no-tag detection position (step S8: YES), whether the passenger is a passenger who needs a ticket (adult or child) is determined based on the outputs of the adult / children sensors 21 and 22. (Step S9). If it is a passenger (adult) who needs a boarding ticket (step S9: YES), it is determined with reference to the determination information queue 73a whether there is determination information (step S10). If the determination information is stored in the determination information queue 73a in step S5, the determination information is present (step S10: YES). Therefore, the determination information is extracted from the determination information queue 73a in the order of reading, and the extracted determination information is used as the passenger. And is recorded in the link table 73b (step S11). Thereafter, the door drive unit 74 opens the gate door 53 (or 54) to allow passengers to pass (step S12).

  On the other hand, if the determination at step S3 is not allowed to pass, the determination information is not stored at step S5, and if there is a remainder of the determination information, it is deleted (step S7), so that the determination information queue 73a has no determination information, and the determination in step S10 is NO. At this time, the link between the person and the determination information in step S11 is not performed, and the gate door 53 (or 54) is closed by the door driving unit 74, and passenger passage is prohibited (step S13). Moreover, if the determination result in step S9 is a passenger (child) who does not require a ticket (step S9: NO), steps S10 and S11 are omitted, and the process proceeds to step S12 to allow passage.

  As described above, according to the above-described embodiment, when it is determined that the vehicle is not allowed to pass, if there is a remainder of the determination information, the remainder is deleted. Passengers in possession are prohibited from passing. Therefore, even if the remainder of the determination information occurs, it is possible to reliably prevent the passage of passengers who should not be allowed to pass. As a result, it is possible to reduce the burden on the attendant by avoiding passage prevention when passing through the next ticket gate apparatus, and to enhance the illegal boarding prevention effect by strict entrance / exit check.

  Further, in the present embodiment, the no-tag detection position is set in the vicinity of the antenna 54, and the person and the determination information are linked almost at the same time when the passerby holds the boarding medium over the antenna 54. There are important implications. In the conventional automatic ticket gate, the link between the person and the determination information is performed in the vicinity of the center position of the passage. Therefore, when it is determined that the following passenger is not allowed to pass, there is a passenger who has not been linked in the passage. There is a case. For this reason, if the determination information remainder is erase | eliminated at the said time, the passenger who has not completed the link in a passage will be prohibited from passing. On the other hand, in this embodiment, since the passenger who entered the passage past the no-tag detection position has completed the link between the person and the determination information, the time when the subsequent passenger is determined to be impassable Then, it is very unlikely that passengers who have not yet been linked exist in the aisle. For this reason, even if the remainder of the determination information is deleted at that time, there is almost no situation where passengers are prohibited from passing through the passage.

  FIG. 16 is a schematic diagram for explaining the principle of determination processing according to another embodiment of the present invention. In the figure, the same parts as those in FIG. Here, it is assumed that two passengers P3 and P4 are staying at the entrance of the automatic ticket gate 50 after the passengers P1 and P2 who have completed the link travel through the passage. The passenger P3 in front can pass the determination result of the boarding medium, but has not reached the no-tag detection position, and therefore the link is not completed. The determination information queue 73a includes determination information remainders Jx and Jy that are not linked. In this state, it is assumed that the rear passenger P4 reaches out, holds the boarding medium over the antenna, and the determination result is impassable. At this time, if all the determination information remainders Jx and Jy are erased, the passenger P3 should be permitted to pass, but the determination information is lost, so the link is not performed and the passage is prohibited.

  Therefore, in order to eliminate this problem, in this embodiment, the determination result for the passenger medium (the riding medium carried by the passenger P3) immediately before the boarding medium (the riding medium carried by the passenger P4) that is determined to be impassable. Is possible and the link between the passenger P3 and the determination information is not completed after the determination of whether or not the vehicle is allowed to pass. The remaining determination information remainder Jx is deleted while the other determination information remainder Jx is deleted. Thereby, since the determination information of the passenger P3 remains without being erased, the determination information and the passenger P3 are linked when the passenger P3 reaches the no-tag detection position, and the passenger P3 can pass. On the other hand, if the determination result for the previous passenger medium is passable and the link between the passenger P3 and the determination information is completed after the passability determination, the determination information is the same as in the previous embodiment. All the remainder is erased.

  FIG. 17 is a flowchart showing a detailed procedure of the determination process in the case of FIG. In FIG. 17, steps that perform the same processing as in FIG. 15 are denoted with the same reference numerals as in FIG. 15. In FIG. 17, steps S14 and S15 are further added to steps S1 to S13 of FIG. If the determination in step S3 is not possible and there is a remainder of the determination information (step S6: YES), the determination result for the previous boarding medium is passable, and it is determined as passenger P3 after this passability determination. It is determined whether or not the link with the information has been completed (step S14). As a result, if the determination result is passable and unlinked (step S14: YES), the remainder of the previous determination information is left and the remaining determination information remainder is cleared (step S15). If the determination result is passable and the link is completed (step S14: NO), all of the determination information remainder is cleared (step S7). The other steps are the same as those in FIG.

  According to the other embodiments described above, when the determination result of the boarding medium is impassable, the determination result of the boarding medium immediately before the boarding medium and the link state are checked, and the determination result is passable and linked. Is not completed, the remainder of the judgment information of the previous recording medium is left and the remainder of the other judgment information is erased, so even if the case shown in FIG. It is possible to avoid the problem that a passenger who should be prevented from passing. In this embodiment, only the remaining judgment information of the previous recording medium is left. However, the present invention is not necessarily limited to this, and passengers can be allowed to pass through any remaining judgment information. There is no problem in doing so, and it is sufficient to leave at least one determination information remainder.

  In the embodiment described above, among the traffic information determined by reading from the boarding medium, information that has been processed in the determination OK is stored in the determination information queue 73a as the determination information. However, the determined traffic information is sequentially applied regardless of the determination result. The information that has been accumulated and that has been processed in the determination OK may be read out as determination information.

  In the embodiment described above, the present invention is applied to an automatic ticket gate installed at a railway station. However, the traffic control device according to the present invention is also applied to an automatic ticket gate installed at an airport or the like. It can also be applied to gate devices installed at entrances and exits of amusement parks and event venues.
