  Queue management (entrance management in the lane) may be performed using a vehicle detector at an entrance / exit of an expressway. That is, a vehicle detector may be used to determine the presence status of a vehicle in the lane (whether there is a vehicle, how many vehicles, etc.). The determination result is used, for example, for controlling the start controller and preventing erroneous charging. Two vehicle detectors are required to perform queue management. That is, a vehicle detector as an entry detector is provided at the end of the lane, and a vehicle detector as an exit detector is provided at the end of the lane.

  In the reverse lane where queue management is performed, in order to switch the operation direction, the operation state of the roadside equipment including the vehicle detector must be switched. When an operator switches the operation state of a roadside device, each device must be operated, and time is spent for the switching work. In addition, if the operation state of some devices is forgotten to be switched, the reverse lane operation is hindered.

  Therefore, an object of the present invention is to provide a reverse lane control system that can quickly and reliably switch the operation state of a reverse lane in which queue management is performed.

  In Patent Document 1, the detection output of the vehicle detection device is switched between the case where the reverse lane is used as the entrance lane and the case where the reverse lane is used as the exit lane, and the toll collection as the entrance lane is performed according to the switched detection output. The point which performs the toll collection process as a process or an exit lane is disclosed. However, there is no disclosure about switching the operation direction in a reverse lane (reverse lane in which queue management is performed) in which an entrance detector and an exit detector are provided.

  A reverse lane control system according to the present invention includes a roadside device installed on the roadside of a reverse lane whose traveling direction is switched between a forward direction and a reverse direction, a control device that controls the roadside device, and the operation of the reverse lane An input device that receives an operation mode instruction indicating a mode and inputs the operation mode instruction to the control device. The roadside device includes a first vehicle detector provided on one end side in the reverse lane and a second vehicle detector provided on the other end side in the reverse lane. When the control device receives an instruction to operate in the forward mode as the operation mode instruction, the first vehicle detector serves as an entry detector in the reverse lane, and the second vehicle detector serves as an exit detector in the reverse lane. Then, it is determined whether there is a vehicle in the reverse lane, and the operation of the roadside device is controlled based on the determination result. When the control device receives an instruction to operate in the reverse mode as the operation mode instruction, the control device uses the first vehicle detector as the exit detector, the second vehicle detector as the entry detector, and the reverse lane. It is determined whether a vehicle exists in the vehicle, and the operation of the roadside device is controlled based on the determination result.

(First embodiment)
First, the first embodiment will be described. FIG. 1 is a schematic diagram showing a reverse lane control system 20 according to the present embodiment.

  The reverse lane control system 20 is provided in the reverse lane 1. The reverse lane 1 is a lane in which the traveling direction of the vehicle is switched between the forward direction and the reverse direction. For example, the reverse lane 1 is used as a switchable lane that can be used as an entrance lane or an exit lane according to the traffic volume and time zone of a toll road. Further, the reverse lane 1 may be a lane that can be operated by reversing the approach side and the start side at a toll gate that collects tolls. The reverse lane 1 can also be understood as a lane that can be switched between an entrance lane and an exit lane as necessary. In the present embodiment, a case will be described in which the reverse lane 1 is used as an entrance lane when the operation direction is a forward direction, and the reverse lane 1 is used as an exit lane when the operation direction is a reverse direction.

  As shown in FIG. 1, the reverse lane control system 20 includes a roadside device 17, a control device 13, and an input device 12.

  The roadside device 17 is provided on the roadside (23-1, 23-2) of the reverse lane 1. The roadside device 17 includes a first vehicle detector 2-1, a second vehicle detector 2-2, an entrance start controller 9-1 (forward start controller), and an exit start controller 9-2 ( Including a reverse direction start controller). The first vehicle detector 2-1 is provided on one end side in the reverse lane 1, and the second vehicle detector 2-2 is provided on the other end side in the reverse lane 1.

  The control device 13 has a function of controlling the roadside device 17 and is realized by, for example, a computer. Here, the control device 13 has a function of performing queue management. That is, the control device 13 determines whether or not a vehicle exists in the reverse lane 1 based on the vehicle detection results by the first vehicle detector 2-1 and the second vehicle detector 2-2. And the control apparatus 13 controls operation | movement of the roadside apparatus 17 based on a determination result. For example, the control device 13 controls each of the start controllers (9-1, 9-2) based on the determination result so that the vehicle does not collide (so that the vehicle is opened when the vehicle passes).

  The input device 12 has a function of receiving information specifying an operation mode of the reverse lane from an operator as an operation mode instruction and inputting the information to the control device 13.

  When the worker inputs an operation mode instruction indicating the forward direction mode via the input device 12, the control device 13 switches the operation of the roadside device 17 so that the operation direction becomes the forward direction. At this time, the control device 13 operates the first vehicle detector 2-1 as an entry detector in the reverse lane 1 and operates the second vehicle detector 2-2 as an exit detector, thereby performing queue management. (Determines whether there is a lane in the reverse lane).

  On the other hand, when the worker inputs an operation mode instruction indicating the reverse direction mode via the input device 12, the control device 13 switches the operation of the roadside device 17 so that the operation direction is the reverse direction. At this time, the control device 13 performs queue management using the first vehicle detector 2-1 as an exit detector and the second vehicle detector 2-2 as an entry detector.

  As described above, according to the present embodiment, the control device 13 switches the operation of the roadside device 17 in accordance with the operation mode instruction. In response to the operation mode instruction, the control device 13 switches the assignment between the entry detector and the exit detector, and the operation state of the roadside device 17 is automatically switched even in the reverse lane 1 where queue management is performed. This makes it possible to quickly and reliably switch the operation direction of the reverse lane in which queue management is performed.

Moreover, the exit intercom 7-2 and the exit roadside indicator 8-2 are provided on the roadside 23-2. In FIG. 3, the illustration of the entrance lane display plate 14-1, the exit lane display plate 14-2, the entrance signal lamp 15-1, and the exit signal lamp 15-2 is omitted.

  A lane server 5 is installed on the roadside 23-1. The lane server 5 is connected to both the entrance device 16-1 and the exit device 16-2. The entrance lane server and the exit lane server do not need to be provided separately.

  Next, the control device 13 will be described. FIG. 4 is a schematic diagram showing the control device 13. As described above, the control device 13 is realized by a computer and includes an arithmetic device 18 (for example, a CPU) and a storage device 19 (a hard disk, a ROM, a RAM, and the like). The storage device 19 stores a control program 21 and an operation state table 22. The configuration shown in FIG. 4 may be provided in the lane server 5 or may be provided in the lane monitoring control device 11. The control device 13 controls the roadside device 17 by executing the control program 21 by the arithmetic device 18.

  The operation state table 22 is referred to by the control device 13 when the operation mode is switched. The operation state table 22 shows the correspondence between the operation mode and the operation state.

  FIG. 5 is a conceptual diagram showing the contents of the operation state table 22. As shown in FIG. 5, the operation status table 22 indicates the operation status of each device included in the roadside device 17 for each operation mode. As the operation mode, “switching”, “entrance operation”, and “exit operation” are shown.

  Next, the input device 12 will be described. FIG. 6 is a schematic diagram showing the input device 12. As shown in FIG. 6, the input device 12 is provided with a “switching” button, an “entrance” button, and an “exit” button for designating an operation mode. In addition, if necessary, you can specify the type of lane (“Dedicated” button, “Mixed” button, “General” button), “Control” button to switch to the selected operation mode, and A “Cancel” button is provided.

  Subsequently, an operation method of the reverse lane control system 20 will be described.

  When changing the operation direction of the reverse lane 1, the worker first presses the “switching” button (see FIG. 6), and then presses the “control” button (see FIG. 6). As a result, information indicating the “switching” mode is input from the input device 12 to the control device 13 as an operation mode instruction. The control device 13 controls the operation of the roadside device 17 according to the operation state table (see FIG. 5). Specifically, as shown in FIG. 5, the entrance start controller 9-1 and the exit start controller 9-2 are in the “closed” state, and the entrance lane display board 14-1 and the exit lane are displayed. The display on the display board 14-2 is "prohibit entry", the display of the entrance signal lamp 15-1 and the exit signal lamp 15-2 is "red" indicating that entry is not possible, and the other devices are stopped or turned off. The roadside device 17 is controlled so that This prohibits the vehicle from entering the reverse lane 1. While the operation mode is “switching”, the worker performs the operation direction switching operation. For example, the worker changes the arrangement of pylon or the like that separates the lanes before and after the reverse lane 1.

  After the work, the worker presses the “entrance” button or the “exit” button (see FIG. 6), and presses the “control” button.

  The operation when the “entrance” button is pressed will be described below. In this case, an operation mode instruction indicating the entrance mode is input from the input device 12 to the control device 13. The control device 13 switches the operation state of the roadside device 17 according to the operation state table (see FIG. 5). Specifically, as shown in FIG. 5, the control device 13 operates the first vehicle detector 2-1 as an entry detector and operates the second vehicle detector 2-2 as an exit detector. Further, in the control device 13, the lane server 5 operates in the entrance operation mode. Furthermore, the entrance vehicle detector 2-3, the license plate reader 3, the entrance first antenna 4-1, the pass ticketing machine 6, the entrance intercom 7-1, the entrance roadside indicator 8-1, the entrance. The start controller 9-1 and the entrance second antenna 4-3 are controlled so as to be in operation. The display on the entrance lane display board 14-1 is switched to “ETC”, and the display on the entrance signal lamp 15-1 is switched to “blue” indicating that entry is possible. The exit antenna 4-2, the exit vehicle detector 2-4, the exit intercom 7-2, and the exit roadside indicator 8-2 are controlled so as to be in an operation stop state or a power-off state. Furthermore, the exit start controller 9-2 is controlled so as to be always in the “open” state. In addition, the display on the exit lane display 14-2 is controlled to be “prohibited entry”, and the exit signal lamp 15-2 is controlled to be “red”.

  When the reverse lane 1 is operated as an entrance lane, the vehicle travels in the forward direction and enters the reverse lane 1 from one end of the reverse lane 1 (see FIG. 3). When the vehicle enters, the first vehicle detector 2-1 detects the vehicle. In addition, communication is performed between the control device 13 and the vehicle-mounted device mounted on the vehicle via the first antenna for entrance 4-1, and information necessary for ETC processing is exchanged. The exit start controller 9-2 is in the “normally open” state as described above. Thereafter, the vehicle is detected by the vehicle detector 2-3. The detection result by the vehicle detector 2-3 is used, for example, for controlling communication with the vehicle-mounted device by the first antenna for entrance 4-1. Thereafter, the control device 13 controls opening and closing of the entrance start controller 9-1 to permit or prohibit the progress of the vehicle. At this time, if necessary, a call is made between the driver of the vehicle and the toll booth worker (acquisition worker) via the entrance intercom 7-1. In addition, necessary information is displayed on the entrance roadside indicator 8-1 (vehicle type, fee, etc.). When the vehicle passes through the entrance start controller 9-1, the passage of the vehicle is detected by the second vehicle detector 2-2. Thereafter, if necessary, communication is performed with the vehicle-mounted device of the vehicle via the entrance second antenna 4-3, and information is exchanged.

  Here, as described above, the control device 13 operates the first vehicle detector 2-1 as an entry detector and operates the second vehicle detector 2-2 as an exit detector. That is, when the first vehicle detector 2-1 detects a vehicle, the control device 13 grasps that one vehicle has entered the reverse lane 1. Further, when the second vehicle detector 2-2 detects the vehicle, the control device 13 grasps that one vehicle has left the reverse lane 1. Then, the control device 13 determines the presence state of the vehicle in the reverse lane 1 (whether there is a vehicle in the reverse lane 1, the number of vehicles existing in the reverse lane 1, etc.) and based on the determination result. Thus, the operation of the roadside device 17 is controlled. For example, even if one vehicle exits from the reverse lane 1, when there is a vehicle in the reverse lane 1 at the time of exit, the control device 13 sets the entrance start controller 9-1. Without switching to the closed state, the vehicle is prevented from contacting the entrance start controller 9-1.

  Next, an operation when the “exit” button is pressed will be described. In this case, an operation mode instruction indicating the exit mode is input from the input device 12 to the control device 13. The control device 13 controls the operation of the roadside device 17 according to the operation state table (see FIG. 5). That is, the control device 13 operates the first vehicle detector 2-1 as an exit detector and operates the second vehicle detector 2-2 as an entrance detector. Further, in the control device 13, the lane server 5 operates in the exit operation mode. Furthermore, the entrance vehicle detector 2-3, the license plate reader 3, the entrance first antenna 4-1, the pass ticketing machine 6, the entrance interphone 7-1, the entrance roadside indicator 8-1, and The entrance second antenna 4-3 is controlled so as to be in an operation stop state or a power OFF state. Further, the entrance start controller 9-1 is controlled so as to be always in the “open” state. Further, the display of the entrance lane display plate 14-1 is controlled to be “prohibited entry”, and the display of the entrance signal lamp 15-1 is controlled to be “red”. Furthermore, the exit antenna 4-2, the exit vehicle detector 2-4, the exit intercom 7-2, the exit roadside indicator 8-2, and the exit start controller 9-2 are put into operation. Controlled. Further, the display on the exit lane display 14-2 is controlled to be “ETC”, and the exit signal lamp 15-2 is controlled to be “blue”.

  When the reverse lane 1 is operated as an exit lane, the vehicle travels in the reverse direction and enters the reverse lane 1 from the other end of the reverse lane 1 (see FIG. 3). When the vehicle enters, the second vehicle detector 2-2 detects the vehicle. Thereafter, communication is performed between the control device 13 and the vehicle-mounted device mounted on the vehicle via the first exit antenna 4-2, and information necessary for ETC processing is exchanged. Thereafter, the vehicle is detected by the exit vehicle detector 2-4. The detection result of the exit vehicle detector 2-4 is used, for example, for control of communication with the vehicle-mounted device by the first exit antenna 4-2. Thereafter, the control device 13 controls the opening / closing of the exit start controller 9-2 to permit or prohibit the vehicle from moving forward. At this time, if necessary, a call is made between the driver of the vehicle and the toll booth worker (acquisition worker) via the exit intercom 7-2. In addition, necessary information (such as a charge) is displayed on the exit roadside indicator 8-1. When the vehicle passes the exit start controller 9-2, the first vehicle detector 2-1 detects the passage of the vehicle.

  Here, as described above, unlike the entrance operation, the control device 13 operates the second vehicle detector 2-2 as an entry detector and uses the second vehicle detector 2-1 as an exit detector. operate. And the control apparatus 13 judges whether a vehicle exists in the reverse lane 1, and controls operation | movement of the roadside apparatus 17 based on a judgment result. For example, when a vehicle remains in the reverse lane 1, even when one vehicle leaves the reverse lane 1, the control device 13 switches the exit start controller 9-2 to a closed state. Without change, the vehicle is prevented from contacting the exit start controller 9-2.

  As described above, according to the present embodiment, the control device 13 switches the operation state of the roadside device 17 based on the operation mode instruction input by the worker. At this time, since the control device 13 switches the vehicle detectors (2-1, 2-2) used as the entry detector and the exit detector, even in the reverse lane 1 where the queue management is performed, the roadside can be easily The operating state of the device 17 can be switched. It is only necessary to input the operation mode instruction via the input device 12, and the time spent for switching the operation direction of the reverse lane 1 is reduced. Further, since the operation state of the roadside device 17 is switched by the control device 13, an erroneous operation is prevented.

  In addition, the slave unit 31 is provided with an identification device 48. The identification device 48 identifies whether the child device 31 is mounted on the parent device 29 or the installation table 30. Specifically, the identification device 48 includes an entrance mode detection contact member 36, a common contact member 37, an exit mode detection contact member 38, and a detection device 47, similar to the slave unit 28 of the communication device 24. On the other hand, a first short bar 39-1 is provided on the upper surface of the main unit 29, and a second short bar 39-2 is provided on the upper surface of the installation table 30. These arrangements are the same as those of the communication device 24. That is, the detection device 47 detects the electrical connection between the contact members (36, 37, 38), thereby identifying whether the child device 31 is mounted on the parent device 29 or the installation table 30. .

  The identification device 48 generates an operation mode instruction indicating the entrance mode and notifies the control device 13 when the child device 31 is mounted on the parent device 29. The identification device 48 generates an operation mode instruction indicating the exit mode and notifies the control device 13 when the slave unit 31 is mounted on the installation table 30. The control device 13 controls the roadside device 17 according to the operation mode instruction.

  Then, an example of the operation | movement method of the reverse lane control system 20 which concerns on this embodiment is demonstrated.

  When switching the operation direction of the reverse lane 1, the worker first presses the “switching” button (see FIG. 6) of the input device 12. As in the first embodiment, the control device 13 controls the operation of the roadside device 17 according to the operation state table 22. That is, the operation of the roadside device 17 is controlled so that the vehicle is prohibited from entering the reverse lane 1.

  Next, the worker performs an operation for changing the operation direction of the reverse lane 1. When the operation state is set to the entry mode, the worker mounts the child device 28 on the parent device 26 and the child device 31 on the parent device 29 (see FIG. 7). As a result, the call device 24 identifies that the handset 28 is mounted on the base device 26, generates an operation mode instruction indicating the entrance mode, and notifies the control device 13. Similarly, in the roadside display device 25, it is identified that the child device 31 is mounted on the parent device 29, and an operation mode instruction indicating the entrance mode is generated and notified to the control device 13.

  After the change work is completed, the worker uses the input device 12 to input an operation state switching execution instruction to the control device 13 (press the “control” button (see FIG. 6)). The control device 13 that has received the execution instruction switches the state of the roadside device 17 in accordance with the operation mode instruction acquired from the call device 24 and the roadside display device 25 as in the first embodiment. That is, the operation state of the roadside device 17 is changed so as to be operated in the entrance mode.

  On the other hand, when the operation state is set to the exit mode, the worker mounts the slave unit 28 on the installation table 27 and mounts the slave unit 31 on the installation table 30. As a result, the call device 24 identifies that the handset 28 is mounted on the installation table 27, generates an operation mode instruction indicating the exit mode, and notifies the control device 13. Similarly, in the roadside display device 25, it is identified that the handset 31 is mounted on the installation base 27, and an operation mode instruction indicating the exit mode is generated and notified to the control device 13. After the change work is completed, the worker uses the input device 12 to input an operation state switching execution instruction to the control device 13. The control device 13 that has received the execution instruction switches the state of the roadside device 17 in accordance with the operation mode instruction acquired from the call device 24 and the roadside display device 25. That is, the operation of the roadside device 17 is controlled so as to be operated in the exit mode.

  When the operation mode instruction by the communication device 24 and the operation mode instruction by the roadside display device 25 indicate different modes, the control device 13 does not execute the instruction even if the execution instruction is received. Thereby, operation in an incorrect mode can be prevented.

  Further, the operation mode instruction by the call device 24 and the operation mode instruction by the roadside display device 25 may be used as an interlock. That is, the worker inputs the operation mode instruction indicating the entrance mode or the exit mode through the input device 12 after performing the operation of changing the operation direction of the reverse lane 1 as in the first embodiment. In this case, the control device 13 operates the roadside device 17 only when the operation mode instruction by the call device 24, the operation mode instruction by the roadside display device 25, and the operation mode instruction input by the worker match. Switch state. Such an operation can reliably prevent erroneous operation.

  As described above, according to the present embodiment, the same effects as those of the first embodiment can be obtained. In addition, a communication device 24 having a parent device 26 and a child device 28 is used in place of the entrance intercom and the exit intercom. Thereby, it is not necessary to provide two intercoms, and the cost can be reduced.

  Similarly, according to the present embodiment, a roadside display device 25 having a slave unit 31 and a master unit 26 is used in place of the entrance roadside indicator. Thereby, it is not necessary to provide two roadside display devices, and the cost can be reduced.

  In the present embodiment, a case has been described in which the handset 28 is mounted on the base unit 26 in the call device 24 during entrance operation (see FIG. 7 and the like). However, the slave unit 28 may be mounted on the master unit 26 at the time of exit operation. In this case, the arrangement of the base unit 26 and the installation base 27 is switched. Similarly, in the roadside display device 25, the slave unit 31 may be mounted on the master unit 29 not at the time of entrance operation but at the time of exit operation.

  In the present embodiment, the case where the “switching” button (see FIG. 6) is first pressed when switching the operation direction has been described. However, it may be determined as “switching” by means other than the “switching” button. For example, the call device 24 or the roadside display device 25 may determine that “switching” is being performed based on the identification result of the child device (28 or 31) by the identification device (46 or 48). For example, when the slave unit (28 or 31) is removed, the slave unit (28 or 31) is connected to the master unit (26 or 29) and the installation base (27 or 30) by the identification device (46 or 48). It may be detected that the terminal is not connected to any of them, and in this case, it may be determined that “switching”. Further, when it is detected that the slave unit (28 or 31) is connected to both the master unit (26 or 29) and the installation base (27 or 30), it is determined that “switching” is in progress. May be. The slave unit (28 or 31) is not connected to either the master unit (26 or 29) and the installation stand (27 or 30), and the master unit (26 or 29) and the installation stand (27 or 30) Since the state connected to both is an abnormal state, the safety can be further improved by determining “switching” and prohibiting the vehicle from entering.

  Moreover, according to this embodiment, the subunit | mobile_unit 28 and the subunit | mobile_unit 31 are rechargeable. Therefore, it is preferable to set the master unit (26, 29) on the road side 23 corresponding to the operation mode with the longer operation time among the entrance mode and the exit mode. Thereby, the charge time of the subunit | mobile_unit 28 and the subunit | mobile_unit 31 can be lengthened, and the operation time by the battery of the subunit | mobile_unit 28 and the subunit | mobile_unit 31 can be shortened. As a result, the frequency of battery replacement is reduced, and maintenance is facilitated.
