  However, in the method using the vehicle detector used in the conventional traffic signal control device, the vehicle cannot be preferentially run as a specific vehicle unless it is equipped with the vehicle detector onboard device. The degree of freedom in setting the vehicle to be driven is low. In addition, it is expensive to mount the vehicle detector on-vehicle device in all the vehicles to be preferentially run.

  An object of the present invention is to provide a specific vehicle priority travel device and method that are low in cost and have a high degree of freedom when setting a vehicle to be preferentially traveled.

In order to achieve the above object, the present invention reads a number assigned to a vehicle during vehicle travel, determines whether the vehicle is a priority vehicle to be preferentially traveled based on the read number, When the determination is made, a vehicle number recognition device that outputs a signal indicating priority vehicle entry, and an output of the vehicle number recognition device as an input, a traffic light that indicates a traffic signal installed on the road is controlled to generate a normal signal pattern Instead of this, a traffic signal control device for displaying a signal of a signal pattern for preferentially driving the priority vehicle is provided .

  Specifically, the vehicle number recognition device includes a number storage means for storing a priority vehicle number, a plurality of vehicle number recognition means for reading the number assigned to the vehicle while the vehicle is running, and the read number as the number. The number stored in the storage means is checked, and when there is a matching number, it is determined that the vehicle is a priority vehicle, and a command signal indicating priority vehicle entry is output together with the identification code of the vehicle number recognition means. Comprising calculating means and communication means for transmitting the output of the calculating means to the traffic signal control device. The traffic signal control device includes a signal pattern database storing a combination of an identification code of the vehicle number recognition means and a signal pattern to be displayed when a priority vehicle is detected by the vehicle number recognition means of the identification code.

  According to the above configuration, any number of vehicles can be recognized as a priority vehicle by the vehicle number recognition device without having to install a special device in the vehicle simply by storing the number of the vehicle to be preferentially driven as the priority vehicle in the number storage means. Is done. When it is recognized as a priority vehicle by the vehicle number recognition device, a command signal indicating that the priority vehicle has been detected is sent to the traffic signal control device together with the identification code of the vehicle number recognition means that detected the priority vehicle, and the traffic signal control device The direction number of the priority vehicle enters the traffic signal from the identification code of the vehicle number recognition means, and a signal pattern that allows the vehicle entering from that direction to pass the signal preferentially Show. As a result, the priority vehicle can preferentially travel without being stopped by a signal.

  Since it is not necessary to mount a special device on the vehicle, the cost can be reduced, and any vehicle can be easily designated as a priority vehicle, and the degree of freedom in designating as a priority vehicle is great.

Further, the number registration means for storing and registering or deleting the priority vehicle number, and the number stored in the number registration means and the registration and deletion are transmitted to the vehicle number recognition device via a communication line. A control unit including a central communication unit is provided separately from the vehicle number recognition device and the traffic signal control device, and the communication unit of the vehicle number recognition device is configured to register and delete a number transmitted via the communication line. and receive another transmitted to said computing means, said computing means you configured to cancel the number stored in the storage or number memory means number storage means number transmitted.

With this configuration, it is avoided that the signal pattern returns to the normal signal pattern before the priority vehicle passes the traffic light, and the signal pattern is changed to the normal signal pattern after the priority vehicle reliably passes the traffic light. Can be restored.

  In this case, either the output of the command signal indicating that the priority vehicle has been detected from the device that reads the number of the vehicle on the exit side, or the preset time from the start of the display of the signal pattern. It may be configured to return to the normal signal pattern at the time when the error occurs. In this way, even if the number of the priority vehicle to leave for some reason is missed, it is not necessary to maintain a signal pattern for preferentially passing the priority vehicle for a long time.

Further, the central communication means is configured to receive the number of the vehicle A and the traveling route information of the vehicle A transmitted in a preset manner, and the control unit is connected to the number registration means and the central communication means. In addition, the route information storage means for storing the number of the vehicle A received by the central communication means and the travel route information on which the vehicle A travels, the road information database storing the road information including the installation position of the traffic light, and the input Based on the travel route information of the vehicle A, comprising a traffic signal that the vehicle A should pass or follow with reference to the road information database, and a central processing means for searching the passing direction when passing the traffic signal, The central communication means is also installed in connection with a traffic signal control device that controls a traffic light to be passed or followed by the vehicle A searched by the central arithmetic means.

The number and passing direction of the vehicle A are received and transmitted to the computing means, and the computing means stores the number and passing direction of the transmitted vehicle A in combination in the number storage means and has priority. When a vehicle entry is detected, the number storage means checks whether the priority vehicle number is stored in combination with the passing direction. If the passing direction is stored in combination, it indicates the priority vehicle entry. In addition to the signal and the identification code of the vehicle number recognition means that has detected the priority vehicle, the number storage means is based on the passing direction stored in combination with the priority vehicle number. In the signal pattern database of the traffic signal control device, the identification code of the vehicle number recognition means and the vehicle number recognition means of the identification code should indicate when the priority vehicle is detected. In addition to the combination of signal patterns, exit from the entry direction for each identification code of the vehicle number recognition means and for each possible exit direction when entering the traffic signal installation position from the side where the vehicle number recognition means is installed The traffic signal control device stores a signal pattern for advancing the priority vehicle in the direction, and the traffic signal control device includes a signal pattern stored in the signal pattern database based on the input identification number of the vehicle number recognition means and the exit direction. the corresponding signal pattern to the traffic signal constituting so current Shimesuru.

In the present embodiment, the vehicle number recognition means 2a to 2h are installed on the beam 5 arranged so as to cross the upper part of the roadway, but may be installed using the arms of the traffic light 4.

  When the number and the identification code of the vehicle number recognition means are input from any of the vehicle number recognition means 2a to 2h, the calculation means 2j refers to the data in the number storage means 2k and the number is stored in the number storage means 2k. Check if it matches what is stored. If they match, the computing means 2j checks the presence or absence of additional information (for example, information on the passing direction described later) stored in the number storage means 2k in combination with the number, and confirms that the priority vehicle is about to enter the intersection. When there is additional information, a command signal indicating the additional information is output to the communication means 2l.

It is configured as follows.

  A terminal device 1f is connected to the central communication means 1a, and the number of the priority vehicle to be registered or the number of the priority vehicle to be deleted is input. The number input from the terminal device 1f is transmitted to the central processing unit 1e via the central communication unit 1a, and the central processing unit 1e stores or deletes it in the number storage unit 1b.

  The control unit 1 is also provided with a signal system central device 1 g and is connected to the control means 3 a of the traffic signal control device 3. The control means 3a transmits the control status of the traffic light, that is, the signal display status to the signal system central apparatus 1g in real time, and the signal system central apparatus 1g analyzes the information transmitted from the control means 3a, The state of the traffic signal control device 3 is managed.

  The control unit 1, the vehicle number recognition device 2, and the traffic signal control device 3 are provided with operation control means (not shown) for controlling the operation of each component, and operate according to a predetermined procedure. Yes.

  The operation of the apparatus having the above configuration will be described below. FIG. 2 schematically shows a situation where the vehicle number recognition device 2, the traffic signal control device 3, and the traffic light 4 are arranged at an intersection.

  The traffic lights 4a to 4d are installed at positions facing vehicles entering the intersection from four roadways. There are other pedestrian signals, but they are not shown in the figure.

  On each roadway, beams 5 are passed in a direction crossing the roadway, and vehicle number recognition means 2a to 2d for reading the number of vehicles entering the intersection and vehicles for reading the number of vehicles leaving from the intersection. Number recognition means 2e-2h are installed. The calculation means 2j, number storage means 2k, and communication means 21 are accommodated in the casing 2m of the vehicle number recognition device 2 and are arranged near the intersection. The vehicle number recognition means 2e to 2h are signal lines and are connected to the inside of the casing 2m. Connected to the computing means 2j.

  The traffic signal control device 3 is connected to the communication means 2l in the housing 2m by a signal line and is arranged in the vicinity of the intersection, and the traffic lights 4a to 4d are all connected to the traffic signal control device 3 by a signal line. ing.

  The vehicle number recognition device 2 and the traffic signal control device 3 are connected to the control unit 1 of the control center via a communication line (not shown).

  A case will be described as an example where the vehicle having the number 1234 is set as the priority vehicle and the intersection where the traffic signal is installed is to be preferentially passed.

  First, the number 1234 is input as the priority vehicle number from the terminal device 1f of the control unit 1 of the control center. The input number is sent to the central processing means 1e via the central communication means 1a, and is stored in the number storage means 1b by the central processing means 1e. At the same time, the central communication means 1a transmits the number 1234 to all the vehicle number recognition devices 2 via the communication line.

  The transmitted number 1234 is received by the communication means 21 of the vehicle number recognition device 2, sent to the calculation means 2j, and stored in the number storage means 2k.

  The number of the vehicle entering the intersection where the traffic signal 4 is installed is read by the vehicle number recognition means 2a to 2d and transmitted to the calculation means 2j together with the identification code of the vehicle number recognition means. The computing means 2j compares the received number with the number stored in the number storage means 2k and confirms whether they match. When there is a matching number, the calculation means 2j determines that the priority vehicle enters from the roadway on which the vehicle number recognition means specified by the identification code is installed, and the priority vehicle enters from the roadway. A command signal indicating that it is to be output is output to the traffic signal control device 3 via the communication means 21.

  In the case of FIG. 2, the priority vehicle of number 1234 is traveling toward the intersection from the roadway on the left side of the figure, and the vehicle number recognition means 2a reads the number 1234, along with the identification code of the vehicle number recognition means 2a. Is transmitted to the computing means 2j. Since the number 1234 has already been stored in the number storage means 2k, the calculation means 2j outputs a command signal to the traffic signal control device 3 that the priority vehicle enters from the left roadway in the figure.

  When the control signal 3a of the traffic signal control device 3 is notified by the command signal from the vehicle number recognition device 2 that the priority vehicle has entered and the roadway into which the priority vehicle has entered, the signal pattern database 3b. The priority traffic signal pattern that preferentially passes vehicles entering the intersection from the roadway through the intersection is read, and the traffic lights 4a to 4d are replaced with the normal signal patterns that have been shown so far. The priority traffic signal pattern is displayed. Note that the time from when the priority vehicle is detected to when the signal pattern is switched varies depending on the traffic volume, the installation position of the vehicle number recognition means 2a, etc., but the details are omitted.

  When the vehicle of number 1234 turns left at the intersection and exits to the upper road in the figure, the number is read by the vehicle number recognition means 2f, and the number 1234 is transmitted to the calculation means 2j together with the identification code of the vehicle number recognition means 2f. The Since the vehicle number recognizing means 2f is a vehicle number recognizing means for reading the number of the vehicle leaving the intersection, the computing means 2j determines that the priority vehicle of number 1234 has passed the intersection and performs traffic signal control via the communication means 21. A return signal for returning the signal pattern to the normal signal pattern is transmitted to the device 3.

  The control means 3a of the traffic signal control device 3 receives the return signal, and causes the traffic lights 4a to 4d to display the normal signal pattern instead of the priority traffic signal pattern that has been shown. In this embodiment, the signal pattern displayed after the fact that the priority vehicle has passed the intersection is confirmed to be switched to the normal signal pattern. However, when the preset time has elapsed, the priority vehicle passes the intersection. Even if it is not confirmed, it is desirable to switch the signal pattern to a normal signal pattern. In addition, when the vehicle number is read by the vehicle number recognition means, the distance between the vehicle position and the intersection may be considered to be constant, and when the decrease in the vehicle speed due to traffic congestion is not expected, the time when the priority traffic signal pattern is displayed May be set in advance, and the signal pattern may be switched to a normal signal pattern after the lapse of time. Furthermore, it is effective if the set time is increased or decreased according to the traffic volume or the time zone.

According to the above-described embodiment, when an arbitrary vehicle is desired to pass preferentially, the vehicle registration number is simply input from the terminal device 1f by the control unit 1, and an intersection with a traffic light is stagnated with a red signal. Therefore, the vehicle can be allowed to pass, and the degree of freedom for setting the priority passing vehicle is increased.
<Embodiment 2>
The first embodiment is an example in which a certain vehicle is set as a priority vehicle. In the present embodiment, when a certain vehicle passes a certain route, a traffic light installed on the route is used as the vehicle. Is controlled so that it can pass preferentially. The system configuration is the same as that described with reference to FIG.

  In the present embodiment, a vehicle that is going to pass the certain route as a priority vehicle is a device that wirelessly transmits the vehicle number (for example, a registration number) and route information indicating the certain route in a predetermined manner. I have. For example, the route information set in the car navigation system may be sent together with the vehicle number to a mobile phone by a preset method and wirelessly transmitted via the mobile phone.

  First, as described above, the central communication means 1a receives the number of the vehicle A and the traveling route information of the vehicle A transmitted by wireless transmission or a mobile phone in a preset method, and receives the received vehicle. The number A and the travel route information on which the vehicle A travels are stored in the route information storage unit 1c via the central processing unit 1e.

  When the central processing unit 1e stores the number of the vehicle A and the travel route information on which the vehicle A travels in the route information storage unit 1c, the road information including the installation position of the traffic signal and the identification code of the vehicle number recognition device related to the traffic signal is obtained. Based on the stored road information database 1d and the input travel route information of the vehicle A, with reference to the road information database 1d, the traffic signal to be passed or followed by the vehicle A and the passing direction when passing the traffic signal and A vehicle number recognition device related to the traffic signal is searched and output to the central communication means 1a together with the vehicle A number.

  Based on the input from the central processing unit 1e, the central communication unit 1a transmits the number of the vehicle A and the passing direction at the traffic signal installation position to the corresponding vehicle number recognition device 2 via the communication line.

  The communication means 2l of the vehicle number recognition device 2 receives the number of the vehicle A transmitted through the communication line and the passing direction at the traffic signal installation position, and outputs it to the calculation means 2j. The calculating means 2j stores the number of the vehicle A in the number storage means 2k and stores the passing direction in combination with the number as additional information.

  The number of the vehicle A entering the intersection where the traffic signal 4 is installed is read by the vehicle number recognition means 2a to 2d and transmitted to the calculation means 2j together with the identification code of the vehicle number recognition means. The computing means 2j compares the received number with the number stored in the number storage means 2k and confirms whether they match. When there is a matching number, the calculation means 2j determines that the priority vehicle enters from the roadway on which the vehicle number recognition means specified by the identification code is installed, and the priority vehicle is about to enter the intersection. A command signal indicating this and a command signal indicating from which roadway the vehicle is going to enter are output to the traffic signal control device 3 via the communication means 21. At the same time, the calculation means 2j confirms whether or not additional information is stored in the number storage means 2k in combination with the number of the vehicle A. If it is stored, the additional information, in this case, the passing direction of the vehicle A is determined. The command signal shown is output to the traffic signal control device 3 via the communication means 21.

  The control means 3a of the traffic signal control device 3 is informed by the command signal from the calculation means 2j of the vehicle number recognition device 2 that the priority vehicle has entered, the roadway in which the priority vehicle enters, and the passing direction. Then, referring to the signal pattern database 3b, a signal pattern (priority traffic signal pattern) that preferentially passes the intersection in the direction notified of the vehicle entering from the roadway toward the intersection is read, and the traffic lights 4a to 4 In 4d, the priority traffic signal pattern is displayed instead of the normal signal pattern that has been displayed so far.

  Subsequent processing is the same as that of the first embodiment, and thus description thereof is omitted.

  According to the present embodiment, in addition to the effects of the first embodiment, since the passing direction of the priority vehicle is specified, it is only necessary to show a signal pattern that gives priority to the vehicle passing in that direction. Thus, there is an effect that the degree of restricting the passage of other vehicles is small, and the congestion of other vehicles and the traffic of pedestrians due to the priority vehicle passage are reduced.

  In each of the above-described embodiments, if the number storage means 2k stores and uses the effective number and effective date of priority traffic as additional information, such as one-time traffic, for example, priority traffic of a large transport vehicle In this case, it is possible to automatically delete the number after the fact, and there is an advantage that a trouble due to forgetting to delete the priority number can be avoided.

Number communication means for storing and registering or deleting the priority vehicle number, and central communication for transmitting the number stored in the number registration means and the registration / deletion to the vehicle number recognition device via a communication line And a communication unit of the vehicle number recognition device that receives the number transmitted via the communication line and the registration / deletion and transmits it to the calculation unit, and the calculation unit Is configured to store the transmitted number in the number storage means or to delete the number stored in the number storage means,
As the vehicle number recognition device, there is installed a device that reads the number of a vehicle that enters the place where the traffic light is installed and the number of the vehicle after passing the traffic signal, and the traffic signal control device is a number of the vehicle on the entry side. Priority from the device that reads the number of the vehicle on the exit side is displayed based on the output indicating that the entry of the priority vehicle from the device that reads the vehicle is detected, and the signal pattern that causes the priority vehicle to run preferentially is displayed on the traffic light. It is configured to return to the normal signal pattern when either the output of the signal indicating the passage of the vehicle is detected or the preset time elapses from the start of the display of the signal pattern. And
The central communication means is configured to receive the number of the vehicle A and the traveling route information of the vehicle A transmitted by a preset method, and the control unit includes the number registration means and the central communication means. In addition, the route information storage means for storing the number of the vehicle A received by the central communication means and the travel route information on which the vehicle A travels, the road information database storing the road information including the installation position of the traffic light, Based on the input travel route information of the vehicle A, the traffic information that the vehicle A should pass or follow with reference to the road information database and the central processing means for searching the passing direction when passing through the traffic signal are included. The central communication means is also connected to a traffic signal control device for controlling a traffic light that the vehicle A searched by the central arithmetic means should pass or follow. The vehicle number recognition device is configured to transmit the number of the vehicle A and the passing direction via the communication line, and the communication means of the vehicle number recognition device transmits from the central communication means via the communication line. The number and passing direction of the vehicle A to be received is transmitted to the calculating means, and the calculating means stores the transmitted number and passing direction of the vehicle A in combination in the number storage means, When an approach is detected, the number storage means checks whether or not the number of priority vehicles is stored in combination with the passing direction. In addition to the identification code of the vehicle number recognition means that has detected the priority vehicle, the number storage means is based on the passing direction stored in combination with the priority vehicle number. The signal pattern database of the traffic signal control apparatus shows the identification code of the vehicle number recognition means and the priority vehicle detected by the vehicle number recognition means of the identification code. In addition to the combination of power signal patterns, for each identification code of the vehicle number recognition means, and for each possible exit direction when entering the traffic signal installation position from the side where the vehicle number recognition means is installed, from the entry direction A signal pattern for advancing the priority vehicle in the exit direction is stored, and the traffic signal control device is configured to store the signal pattern stored in the signal pattern database based on the input identification number of the vehicle number recognition means and the exit direction. A specific vehicle preferential travel device characterized in that a corresponding signal pattern is displayed on a traffic light.
