[Problems to be solved by the invention]
By the way, at toll gates on toll roads, “ETC-only” lanes that allow a plurality of lanes to pass exclusively through vehicles equipped with ETC on-board equipment, for example, ETC on-board equipment is not installed. Set to either the “General” lane that allows vehicles with no on-board equipment to pass exclusively, or the “ETC / General” lane that allows both vehicles with and without ETC on-board equipment to pass through. Corresponding to each lane, by displaying a traffic classification such as “ETC only”, “general” and “ETC / general”, the driver is guided to an appropriate lane. Conventionally, such lanes are set by monitoring the traffic volume by time zone or toll booth staff.
[0006]
However, in the case of setting the lane based on the time zone, for example, when the traffic volume of one vehicle out of the vehicle equipped with the ETC on-board device and the vehicle not equipped with the ETC on-vehicle device is concentrated and increased, the lane of any vehicle becomes There was a problem of traffic jams. In addition, if the lane setting is performed based on the monitoring of the traffic volume by the toll booth staff, there is a problem that human labor is required.
[0007]
Furthermore, as another problem, in an ETC onboard lane, the ETC antenna needs to always emit radio waves from the ETC antenna in order to perform narrow-area wireless communication with the ETC onboard equipment. It is difficult to say that setting an “ETC-only” lane or an “ETC / general” lane under the situation where the possibility of a vehicle equipped vehicle passing through is extremely low, it is difficult to say that it consumes power efficiently. There was a problem that could not be realized.
[0008]
The present invention has been made in view of the above-described circumstances, and a first object is to provide a traffic control system that can effectively utilize a finite lane without requiring human labor. and Gated Place It is to provide. The second purpose is a traffic control system that can appropriately realize power saving. and Gated Place It is to provide.
[0009]
[Means for Solving the Problems]
According to the traffic control system described in claim 1, the electronic license plate mounted on the vehicle stores ETC on-board device mounting presence / absence information indicating whether or not the vehicle is mounted with the ETC on-board device. ETC on-board unit mounting presence / absence information is read from the electronic license plate by the ETC on-board unit mounting presence / absence information reading means. Received And the control means is Received Based on the information on whether ETC OBE is installed or not, calculate the traffic volume of vehicles equipped with ETC OBE and those of vehicles without ETC OBE that are not equipped with ETC OBE. Based on the calculated traffic volume, it is classified into ETC on-vehicle equipment-equipped vehicle lanes that can be passed and ETC on-vehicle equipment-non-equipped vehicles lane that can pass The setting result is notified by the notification means.
[0010]
Thus, unlike the conventional one, without requiring human labor, for example, when the traffic volume of the vehicle equipped with the ETC on-board device is larger than the traffic volume of the vehicle not equipped with the ETC on-vehicle device, the vehicle equipped with the ETC on-vehicle device. Set more lanes ("ETC dedicated" lanes or "ETC / general" lanes) than lanes with no ETC on-board unit ("general" lanes or "ETC / general" lanes). When the traffic volume of vehicles without equipment is larger than the traffic of vehicles equipped with ETC equipment, finite lanes are equipped with ETC equipment, such as setting more lanes without ETC equipment than vehicles with ETC equipment. Depending on the traffic volume of vehicles and the traffic volume of vehicles not equipped with ETC on-board equipment, it can be optimally sorted and set to vehicle lanes equipped with ETC on-board equipment and car lanes not equipped with ETC on-board equipment. It is possible to effectively take advantage of.
[0011]
According to the traffic control system described in claim 2, when the control means changes and sets the predetermined lane between the ETC on-board unit mounted vehicle lane and the ETC onboard unit non-mounted vehicle lane, The setting unit is notified of the setting result at a change timing based on the traffic volume. Thereby, for example, when the traffic volume per unit time is less than a predetermined amount, that is, when the vehicle is not congested, the notification of the setting result is permitted, and the traffic volume per unit time is equal to or greater than the predetermined amount. In other words, by prohibiting the notification of the setting result when the vehicle is congested, the driver can change the number of lanes and the ratio of the vehicle lane with ETC onboard equipment or the vehicle lane without ETC onboard equipment. Confusion can be avoided and safety can be appropriately ensured.
[0012]
According to the traffic control system described in claim 3, the control means is configured to be able to control the supply of operating power of the ETC control device that controls whether or not the vehicle equipped with the ETC on-board device is allowed to pass, and the predetermined lane is connected to the ETC on-board device. When changing and setting between the on-vehicle lane and the ETC on-vehicle equipment non-on-vehicle lane, the supply of operating power to the ETC control device corresponding to the lane is controlled. As a result, for example, when changing from an ETC on-vehicle equipment non-equipped vehicle lane to an ETC on-vehicle equipment equipped vehicle lane, the operation power supply to the ETC control device corresponding to the lane is started. When the ETC onboard equipment lane is changed from the ETC onboard equipment lane to the lane, the operation power supply to the ETC control device corresponding to the lane is stopped, so that the ETC onboard equipment lane is changed. Operating power can be supplied to the ETC control device only at the time of setting, and power saving can be appropriately realized.
[0013]
According to the traffic control system described in claim 4, the electronic license plate mounted on the vehicle stores ETC on-board device mounting presence / absence information indicating whether or not the vehicle is mounted with the ETC on-board device. ETC on-board unit mounting presence / absence information is read from the electronic license plate by the ETC on-board unit mounting presence / absence information reading means. Received And the control means is Received Based on the ETC on-board device mounting presence / absence information, it controls the supply of operating power to an ETC control device that controls whether or not an ETC on-board device on-board device on which the ETC on-board device is mounted is controlled. As a result, unlike the conventional one, for example, when it is predicted that the vehicle equipped with the ETC on-board unit is extremely low in traffic, it is possible to save power by stopping the supply of the operating power to the ETC control device. It can be realized appropriately.
[0014]
According to the gate device described in claim 5, the ETC on-board device mounting presence / absence information indicating whether or not the vehicle is mounted with the ETC on-board device from the electronic license plate mounted on the vehicle is the ETC on-board device mounting presence / absence information. By reading means Received And the control means is Received Based on the information on whether ETC OBE is installed or not, calculate the traffic volume of vehicles equipped with ETC OBE and those of vehicles without ETC OBE that are not equipped with ETC OBE. Based on the calculated traffic volume, it is classified into ETC on-vehicle equipment-equipped vehicle lanes that can be passed and ETC on-vehicle equipment-non-equipped vehicles lane that can pass The setting result is notified by the notification means.
[0015]
Accordingly, the same effect as that described in claim 1 can be obtained, that is, without requiring human labor, a finite lane can be connected to the traffic volume of an ETC on-board device or an ETC on-board vehicle. It is possible to optimally sort and set the vehicle lane with the ETC on-vehicle device or the vehicle lane without the ETC on-vehicle device according to the traffic volume of the vehicle without the device, and the finite lane can be used effectively.
[0016]
According to the gate device described in claim 6, the ETC on-board device mounting presence / absence information indicating whether or not the vehicle is mounted with the ETC on-board device from the electronic license plate mounted on the vehicle is the ETC on-board device mounting presence / absence information. By reading means Received And the control means is Received Based on the ETC on-board device mounting presence / absence information, it controls the supply of operating power to an ETC control device that controls whether or not an ETC on-board device on-board device on which the ETC on-board device is mounted is controlled. Thus, the same effect as that described in claim 4 can be obtained. That is, for example, when it is predicted that the possibility that the vehicle equipped with the ETC onboard equipment will pass is very low, By stopping the supply of operating power, it is possible to appropriately realize power saving.
[0018]

[0030]
The electronic license plate 9 is mechanically attached to a predetermined position of a license plate 23 disposed at the front end of the vehicle 1, and is used for vehicle verification information such as a vehicle registration number and vehicle specification information. In addition, ETC onboard equipment mounting presence / absence information indicating whether or not the vehicle 1 is equipped with the ETC onboard equipment 22 is stored. The ETC on-board device mounting presence / absence information is stored in the electronic license plate 9 when, for example, a specific operator sets up the ETC on-board device 22 and writes it into the electronic license plate 9 (inputs data).
[0031]
Next, the effect | action of an above-described structure is demonstrated with reference to FIG. 3 and FIG. Here, FIG. 3 and FIG. 4 show the processing performed by the control unit 10 of the gate control device 4 as a flowchart.
[0032]
In the gate control device 4, the control unit 10 monitors whether or not the narrow area wireless communication is started between the electronic license plate 9 and the ELP antenna 3 (step S <b> 1), and the change timing described later in detail. Is monitored (step S2).
[0033]
The control unit 10 narrows between the electronic number plate 9 and the ELP antenna 3 as the vehicle 1 on which the electronic number plate 9 is mounted passes through the communication area formed by the ELP antenna 3. When it is detected that regional wireless communication has started ("YES" in step S1), the all-passage vehicle counter stored in the vehicle counter storage unit 14 is incremented (step S3) and received from the electronic license plate 9 The ETC on-board device mounting presence / absence information is identified (step S4).
[0034]
Here, the control unit 10 detects “Yes” as a result of identifying the ETC on-board device mounting presence / absence information received from the electronic license plate 9, that is, the vehicle 1 that has passed through the ETC on-board device mounting presence / absence identification zone is detected. When it is detected that the vehicle is equipped with the on-vehicle device 22 (“YES” in step S5), the ETC on-vehicle device-mounted vehicle counter stored in the vehicle counter storage unit 14 is incremented (step S5). S6).
[0035]
Next, the control unit 10 determines whether or not any of the lanes La to Lc is set as an “ETC dedicated” lane or an “ETC / general” lane at that time (step S7). When the control unit 10 detects that any of the lanes La to Lc is not set as an “ETC-dedicated” lane or an “ETC / general” lane at that time (“NO” in step S7), A predetermined lane among the lanes La to Lc is set as an “ETC dedicated” lane or an “ETC / general” lane (step S8).
[0036]
Next, the control unit 10 causes the ETC control devices 5a to 5c corresponding to the corresponding lane to output power supply start signals from the ETC control device power control unit 12, and the operations of the ETC control devices 5a to 5c corresponding to the corresponding lane. Is started (step S9). Then, the control unit 10 causes the traffic classification indicators 6a to 6c corresponding to the corresponding lane to output display control signals, and causes the traffic classification indicators 6a to 6c corresponding to the corresponding lane to be “dedicated to ETC” or “ETC / The display of the traffic classification is changed so that “general” is displayed (step S10).
[0037]
On the other hand, the control unit 10 detects “none” as a result of identifying the ETC on-board device mounting presence / absence information received from the electronic license plate 9, that is, the vehicle 1 that has passed through the ETC on-board device mounting presence / absence identification zone. Detects that the vehicle is equipped with an ETC vehicle-mounted device that is not equipped with the ETC vehicle-mounted device 22 (“NO” in step S5), the vehicle counter storage unit 14 stores an ETC vehicle-mounted device non-mounted vehicle counter incremented. (Step S11).
[0038]
The control unit 10 increments the ETC on-vehicle device mounted vehicle counter in this way, or increments the ETC on-vehicle device non-mounted vehicle counter, and then the traffic volume and ETC of the ETC on-vehicle device mounted vehicle per unit time. The traffic volume of the vehicle not equipped with the vehicle-mounted device is calculated (step S12). Then, based on the calculated result, the control unit 10 sets the “ETC dedicated” lane, the “ETC / general” lane, the “general” lane, and the “no-go” lane at that time, that is, sets the traffic classification. It is determined whether or not there is a need to change (step S13).
[0039]
Here, the control unit 10 calculates the traffic volume of the vehicle equipped with the ETC on-board device and the traffic volume of the vehicle not equipped with the ETC on-vehicle device per unit time, the “ETC dedicated” lane, “ETC / general” at that time. When the setting of the lane, the “general” lane, and the “no-go” lane is appropriate, it is determined that there is no need to change the traffic classification (“NO” in step S13), and the above-described steps S1 and S2 are performed. Return to.
[0040]
On the other hand, the control unit 10 calculates the traffic volume of the vehicle equipped with the ETC on-board device and the traffic volume of the vehicle not equipped with the ETC on-vehicle device per unit time, the “ETC dedicated” lane, “ETC / When the settings for the “general” lane, “general” lane, and “no-go” lane are not appropriate, that is, for example, the traffic volume of a vehicle equipped with an ETC on-board device is much larger than that of a vehicle not equipped with an ETC on-board device. Nevertheless, when the number of “ETC-dedicated” lanes or “ETC / general” lanes is very small, and conversely, for example, the traffic volume of vehicles not equipped with ETC on-board equipment is the traffic volume of cars equipped with ETC on-board equipment. If the number of “general” lanes or “ETC / general” lanes is extremely small, it is determined that it is necessary to change the setting of the traffic classification (in step S13). YES ”), calculated traffic volume of ETC on-board equipment-equipped vehicles and traffic volume of vehicles without ETC on-board equipment per unit time,“ ETC-only ”lane,“ ETC / general ”lane,“ general ”lane and“ The traffic division change information is created so as to correspond to the setting of the “no traffic” lane (step S14), and the process returns to the above-described steps S1 and S2.
[0041]
Then, when the control unit 10 detects that the change timing has been reached after creating the traffic segment change information in this way ("YES" in step S2), the traffic segment change created earlier than this The settings of the lanes La to Lc are changed based on the information. In this case, the control unit 10 calculates the traffic volume per unit time based on the all-passenger vehicle counter, for example, when the traffic volume per unit time is less than a predetermined amount, that is, when there is no traffic jam, It detects that it became. This is to avoid confusion of the driver because the driver may be confused if the display of the traffic classification is changed when the traffic is heavy. Further, it may be determined whether or not it is a change timing at a predetermined time set within a day or when the number of vehicles 1 that have passed through reaches a predetermined number set in advance.
[0042]
Next, when changing the setting of the lanes La to Lc, the control unit 10 changes from the “general” lane or the “passage” lane to the “ETC dedicated” lane or the “ETC / general” lane, that is, ETC control. It is determined whether or not there is a change from a state that does not require the operation of the devices 5a to 5c to a state that requires the operation of the ETC control devices 5a to 5c (step S15).
[0043]
Here, when the control unit 10 detects that it is necessary to change from the “general” lane or the “no-go” lane to the “ETC dedicated” lane or the “ETC / general” lane (“YES” in step S15). Then, the ETC control device power control unit 12 outputs a power supply start signal to the ETC control devices 5a to 5c corresponding to the corresponding lane, and starts the operation of the ETC control devices 5a to 5c corresponding to the corresponding lane (step S16). ).
[0044]
Next, the control unit 10 causes the traffic classification indicators 6a to 6c corresponding to the corresponding lane to output display control signals based on the traffic classification change information, and causes the traffic classification indicators 6a to 6c corresponding to the corresponding lane to “ “ETC exclusive”, “general”, “ETC / general” or “no traffic” is displayed, and the display of the traffic classification is changed (step S17).
[0045]
Next, the control unit 10 changes the setting of the lanes La to Lc from the “ETC dedicated” lane or the “ETC / general” lane to the “general” lane or the “no-go” lane, that is, ETC control. It is determined whether or not there has been a change from a state that requires operation of the devices 5a to 5c to a state that does not require operation of the ETC control devices 5a to 5c (step S18).
[0046]
When the control unit 10 detects that the “ETC-dedicated” lane or the “ETC / general” lane is changed to the “general” lane or the “no-go” lane (“YES” in step S18), the ETC control is performed. The power supply stop signal is output from the device power control unit 12 to the ETC control devices 5a to 5c corresponding to the corresponding lane, and the operations of the ETC control devices 5a to 5c corresponding to the corresponding lane are stopped (step S19). And the control part 10 initializes a change timing (step S20), and returns to above-described step S1, S2.
[0047]
By the way, the above assumes that the electronic license plate 9 is mounted on all the vehicles 1, and the traffic volume of ETC onboard equipment mounted vehicles and the ETC onboard equipment non-mounted on all vehicles 1 (as a parameter). Although it is possible to calculate the traffic volume of a car, the ratio of the vehicles 1 on which the electronic license plate 9 is mounted even when the electronic license plate 9 is not mounted on all the vehicles 1 If is a certain value, it can be applied.
[0048]
In addition, the above is configured to calculate the traffic volume of the ETC onboard device boarding vehicle and the traffic volume of the vehicle not equipped with the ETC onboard device every time one vehicle 1 passes, in order to reduce the load, The traffic volume of the vehicle equipped with the ETC on-board device and the traffic volume of the vehicle not equipped with the ETC on-vehicle device are collectively calculated every time the vehicle 1 passes through a plurality of vehicles (for example, 10 vehicles) instead of every time the vehicle 1 passes. You may comprise. Furthermore, it is determined whether it is necessary to change the lane setting by calculating the ratio of vehicles equipped with ETC on-board equipment to vehicles not equipped with ETC on-board equipment, and the ratio of cars equipped with no ETC on-board equipment to vehicles equipped with ETC on-board equipment. You may comprise so that it may do.
[0049]
As described above, according to the present embodiment, ETC on-board unit mounting presence / absence information indicating whether or not the vehicle 1 has the ETC on-board unit 22 mounted on the electronic license plate 9 mounted on the vehicle 1 is stored. In the gate device 2, when the ETC on-board device mounting presence / absence information is read from the electronic license plate 9, the ETC on-board device mounting vehicle on which the ETC on-board device 22 is mounted based on the read ETC on-board device mounting presence / absence information is read. Calculate the traffic volume and the traffic volume of vehicles not equipped with the ETC on-board unit 22 that are not equipped with the ETC on-board unit 22, and use the ETC on-board unit mounted vehicle lane (the “ETC-only” lane) based on the calculated traffic volume. Or it is configured to be set separately for “ETC / general” lanes) or ETC on-vehicle equipment non-equipped vehicle lanes (“general” lanes or “ETC / general” lanes). Without requiring human labor, finite lanes can be used for ETC on-board equipment lanes or ETC on-board equipment non-vehicle lanes according to the traffic volume of vehicles equipped with ETC on-board equipment and the traffic volume of vehicles not equipped with ETC on-board equipment. Optimum separation can be set and finite lanes can be used effectively.
[0050]
In this case, since the display of the traffic classification is changed when the traffic volume per unit time is less than the predetermined amount, the number of lanes of the vehicle lane with the ETC on-board device or the vehicle lane without the ETC on-board device is changed. The driver can be prevented from being confused by changing the ratio, and safety can be appropriately ensured.
[0051]
Furthermore, in this case, when changing from an ETC on-vehicle device non-equipped vehicle lane to an ETC on-vehicle device-equipped vehicle lane, starting to supply operating power to the ETC control devices 5a to 5c corresponding to the corresponding lane, On the other hand, when changing from an ETC onboard equipment lane to an ETC onboard equipment lane to set, the supply of operating power to the ETC control devices 5a to 5c corresponding to the corresponding lane is stopped. Therefore, the operating power can be supplied to the ETC control devices 5a to 5c only when setting the ETC onboard equipment mounted vehicle lane, and power saving can be appropriately realized.
[0052]
The present invention is not limited to the embodiments described above, and can be modified or expanded as follows.
You may comprise so that operation | movement of all the ETC control apparatuses may be stopped when the time when the vehicle in which the ETC onboard equipment is mounted passes and the other vehicle does not pass continues for a predetermined time.
When changing the traffic classification of the lane, the configuration may be such that the traffic classification of only a specific lane is changed. For example, the traffic classification is changed based on a preset change pattern according to the time zone. It may be.
For traffic volume of vehicles equipped with ETC on-board equipment and traffic volume of cars not equipped with ETC on-board equipment, past data, dates (weekdays or holidays), staff work style (working or resting), “general” lane or “ETC” The configuration may be such that the traffic classification is changed in consideration of the number of staff members that can be placed in the “/ general” lane.
