The present invention also relates to the traffic control system to control the vehicle and human traffic.

A traffic light installed on the road generally has a configuration in which, for example, switching control is performed based on switching control timing set in advance in time, or switching control is performed by operating a push button. On the other hand, in the following Patent Document 1, in a traffic light switching control device arranged at an intersection, traffic information is predicted by analyzing position information and route information received from an in-vehicle navigation device, and the predicted traffic volume is Based on this, what performs switching control of traffic lights is described.
JP 2002-56495 A

  However, in what is described in Patent Document 1 described above, since traffic volume is predicted and traffic signal switching control is performed, if the accuracy of traffic volume prediction is low, the traffic signal is determined according to the actual traffic volume. There is a problem that the dynamic switching control cannot be appropriately performed.

The present invention has been made in view of the above, and its object is to provide a traffic control system that can appropriately perform dynamic switching control of the traffic signal according to the actual traffic volume is there.

According to the traffic control system described in claim 1, at least one of the in-vehicle device and the mobile terminal transmits a switching request signal to the traffic light switching control device, and the traffic light switching control device has another traffic light switching control device. It is configured to be able to collect the switching status of other traffic signals subject to switching control, and when a switching request signal is received from at least one of the in-vehicle device and the portable terminal, the received switching request signal is signal-processed. , Based on the reception status of the received switching request signal, perform switching control of the traffic light so as to allow at least one of the in-vehicle device and the portable terminal that transmitted the switching request signal , The switching status notification signal including the switching status of the traffic signal subject to switching control and the switching status of other traffic signals is at least one of the in-vehicle device and the portable terminal. And transmits it to either. When at least one of the in-vehicle device and the portable terminal receives the switching status notification signal from the traffic signal switching control device, the switching status of the traffic signal included in the received switching status notification signal is notified .

Thus, unlike the conventional one that performs traffic signal switching control by predicting traffic volume, the switching request signal actually transmitted from at least one of the in-vehicle device and the mobile terminal and received by the traffic signal switching control device. The actual traffic volume (number of vehicles) is controlled by switching the traffic lights so as to allow at least one of the in-vehicle device and the mobile terminal that transmitted the switching request signal to pass through the intersection based on the reception status of It is possible to appropriately perform dynamic switching control of traffic lights according to the number of persons). In addition, the switching status of the traffic light can be notified to the user by the in-vehicle device or the portable terminal that has transmitted the switching request signal.

  According to the traffic control system described in claim 2, at least one of the in-vehicle device and the mobile terminal transmits a switching request signal having the same weight regardless of the type of the vehicle or the person to the traffic signal switching control device. When the switching request signal is received from at least one of the in-vehicle device and the portable terminal, the control device transmits the switching request signal when the received number of times of the received switching request signal reaches a specified number of times, and Traffic light switching control is performed so as to allow at least one of the mobile terminals to pass through the intersection. Thereby, switching control of the traffic light can be performed simply according to the number of vehicles waiting for the signal and the number of people.

  According to the traffic control system described in claim 3, the traffic light switching control device determines whether or not the number of times of reception of the switching request signal received from at least one of the in-vehicle device and the portable terminal has reached a specified number. In addition, the switching control timing set in advance is determined, and the passage of the intersection is permitted before the number of times of receiving the switching request signal received from at least one of the in-vehicle device and the portable terminal reaches the specified number. When the switching control timing comes, priority is given to the switching control timing, and traffic signal switching control is performed so that at least one of the in-vehicle device and the mobile terminal is allowed to pass through the intersection.

  As a result, even if the number of receptions of the switching request signal received from the vehicle or person waiting for the signal does not reach the specified number of times, if the switching control timing set in advance is reached, the switching control timing is given priority. Signal switching control can be performed, and it is possible to prevent a signal waiting time of a vehicle or a person waiting for a signal from being prolonged unnecessarily.

  According to the traffic control system described in claim 4, at least one of the in-vehicle device and the mobile terminal transmits a switching request signal having a different weight related to the type of the vehicle or the person to the traffic signal switching control device. When the weight of the switching request signal received from at least one of the in-vehicle device and the mobile terminal reaches a specified score, the switching control device is connected to at least one of the in-vehicle device and the mobile terminal that transmitted the switching request signal. On the other hand, the traffic light switching control is performed so as to allow passage of the intersection. As a result, the signal waiting time can be varied according to the type of vehicle or person waiting for the signal (for example, an emergency vehicle or a vehicle in a specific area), and the switching control of the traffic light can be performed flexibly.

  According to the traffic control system described in claim 5, the traffic light switching control device determines whether or not the weighting score of the switching request signal received from at least one of the in-vehicle device and the portable terminal has reached a specified score. The switching control timing set in advance is determined, and the intersection is passed before the weighted score of the switching request signal received from at least one of the in-vehicle device and the portable terminal reaches the specified score. When the switching control timing to be permitted comes, priority is given to the switching control timing, and the traffic signal switching control is performed so that at least one of the in-vehicle device and the portable terminal is allowed to pass through the intersection.

  As a result, even if the weight of the switching request signal received from the vehicle or person waiting for the signal does not reach the specified score, the switching control timing is prioritized if the switching control timing set in advance is reached. In the same way as described in claim 3 above, it is possible to avoid the signal waiting time of a vehicle or a person waiting for a signal from being unnecessarily prolonged. it can.

According to the traffic control system described in claim 6 , the traffic light switching control device is a portable terminal in the past when a switching request signal including device identification information for identifying the in-vehicle device is received from the in- vehicle device. When a switching request signal including terminal identification information for identifying the mobile terminal is received, a signal waiting notification signal indicating that a person is waiting for a signal is transmitted to the in-vehicle device. When the signal waiting notification signal is received from the traffic light switching control device, it notifies that the person is waiting for the signal. Thereby, it is possible to notify the user that a person is waiting for a signal on the in-vehicle device, and to prompt the user who is driving the vehicle to be aware of the pedestrian.

According to the traffic control system described in claim 7 , the traffic light switching control device is a vehicle-mounted device in the past when a switching request signal including terminal identification information for identifying the mobile terminal is received from the mobile terminal. When a switching request signal including device identification information for identifying the in-vehicle device is received from the mobile terminal, a signal waiting notification signal indicating that the vehicle is waiting for the signal is transmitted to the mobile terminal. When the signal waiting notification signal is received from the traffic light switching control device, the vehicle is notified that the signal is waiting. Accordingly, the user can be notified that the vehicle is waiting for a signal on the portable terminal, and the user who is walking can be alerted to the vehicle.

  The narrow-area wireless communication referred to in the above configuration is, for example, Bluetooth (registered trademark), a wireless LAN, or the like. In this case, the narrow area wireless communication between the in-vehicle navigation device 2 and the traffic light switching control device 5 and the narrow area wireless communication between the portable information terminal 4 and the traffic light switching control device 5 are in the same frequency band. The frequency bands may be different from each other. Further, in the traffic light switching control device 5, the narrow area wireless unit 52 is configured to form an area around the intersection where the traffic light switching control device 5 is disposed as a narrow area wireless communication area.

  Next, the operation of the above configuration will be described with reference to FIGS. Here, FIG. 2 shows a process performed by the control unit 21 of the in-vehicle navigation device 2 as a flowchart, FIG. 3 shows a process performed by the control unit 41 of the portable information terminal 4 as a flowchart, and FIG. The process which the control part 51 of the traffic light switch control apparatus 5 performs is shown as a flowchart.

  In this case, the traffic light switching control device 5 receives the switching request signal from the in-vehicle navigation device 2 and receives the switching request signal from the portable information terminal 4 to receive signals from both the vehicle and the person waiting for the signal. The description will be made on the assumption that the switching request is handled. In addition, the traffic signal switching control device 5 periodically receives a switching status notification signal from a traffic signal to be switched by itself, and the switching status notification signal is externally transmitted from another traffic signal switching control device. By periodically inputting to the interface unit 54, it is possible to update the switching status of the traffic signal that is subject to switching control by itself and the switching status of the traffic signal that is subject to switching control by another traffic signal switching control device. This will be explained as a premise.

  In the in-vehicle navigation device 2, the control unit 21 determines whether or not a switching request signal transmission trigger has occurred (step S <b> 1), and detects the occurrence of a switching request signal transmission trigger (step S <b> 1 indicates “ YES ”), the device identification information is read out from the memory 31 and, as shown in FIG. 5, a switching request signal including the read out device identification information is transmitted from the narrowband radio unit 27 (step S2). In this case, the transmission request signal transmission trigger includes, for example, several cases such as the vehicle stopping near the intersection and waiting for the signal, the user performing a predetermined operation, and the like. The condition combined with is established.

  In the portable information terminal 4, the control unit 41 determines whether or not a switching request signal transmission trigger has occurred (step S11), and detects the occurrence of a switching request signal transmission trigger (in step S11, “ YES ”), the terminal identification information is read from the memory 47, and as shown in FIG. 5, a switching request signal including the read terminal identification information is transmitted from the narrowband radio unit 27 (step S12). In this case, the switching request signal transmission trigger includes several cases such as a user waiting for a signal near an intersection, a user performing a predetermined operation, and the like, which are combined alone or in combination. The condition is satisfied.

  In the traffic light switching control device 5, the control unit 51 determines whether or not the switching request signal is received from the in-vehicle navigation device 2 by the narrow area wireless unit 52 (step S21), and the switching request signal from the portable information terminal 4 is narrow. It is determined whether or not it has been received by the local radio unit 52 (step S22), and it is determined whether or not the switching control timing set in advance has been reached (step S23). Here, when the control unit 51 detects reception of the switching request signal from the in-vehicle navigation device 2 (“YES” in step S21) or detects reception of the switching request signal from the portable information terminal 4 (step S21). “YES” in S22), the received switching request signal is signal-processed (step S24), and it is determined whether or not the conditions for switching control are satisfied (step S25).

  In this case, as a condition for the switching control, for example, if the number of times of reception of the switching request signal is used as a determination material, the number of times of reception of the switching request signal from the in-vehicle navigation device 2 or the portable information terminal 4 is set to a predetermined number. If the weighted score of the switching request signal is used as a criterion, for example, the in-vehicle navigation device 2 or the portable information terminal 4 transmits the switching request signal including the weighted score. The condition is that the weighting points of the switching request signals from the navigation device 2 and the portable information terminal 4 have reached a predetermined number of points.

  Then, when the control unit 51 detects that the condition for the switching control is satisfied (“YES” in step S25), the control unit 51 is a traffic signal to be controlled by itself so as to allow passage of the intersection (so that it lights in blue). Is switched by the traffic signal interface unit 53 (step S26), and the process returns to the above-described steps S21 to S23.

  On the other hand, when the control unit 51 detects that the condition for the switching control is not satisfied ("NO" in step S25), as shown in FIG. The in-vehicle navigation device which is the transmission source of the switching request signal from the narrow-band radio unit 52 including the switching status and the latest switching status of the other traffic signal to be controlled by the other traffic signal switching control device 2 or the portable information terminal 4 is transmitted (returned) (step S27). In this case, if the information on the traveling direction of the vehicle or the person is notified from the in-vehicle navigation device 2 or the portable information terminal 4, the control unit 51 displays the latest switching status of other traffic lights arranged in the traveling direction. The included switching status notification signal is transmitted from the narrow-band radio unit 52 to the in-vehicle navigation device 2 or the portable information terminal 4 that is the transmission source of the switching request signal.

  In addition, when the control unit 51 detects that the switch control timing is reached regardless of the reception status of the switch request signal from the in-vehicle navigation device 2 or the portable information terminal 4 (“YES” in step S23), in this case In addition, the traffic signal interface unit 53 is caused to perform switching control of the traffic signal that is itself subject to switching control so as to permit passage of the intersection (so that it lights in blue) (step S26).

  In the in-vehicle navigation device 2, the control unit 21 determines whether or not the switching state notification signal is received from the traffic light switching control device 5 by the narrow area wireless unit 27 (step S <b> 3). When the reception of the switching status notification signal is detected (“YES” in step S3), the traffic signal switching status is extracted from the received switching status notification signal, and as shown in FIG. Is displayed on the display device 8 (step S4) (see P1 to P3 in FIG. 8). Thereby, not only the switching situation of the traffic signal waiting for the signal but also the switching situation of the surrounding traffic lights can be notified to the user who is driving the vehicle.

  In the portable information terminal 4, the control unit 41 determines whether or not the switching state notification signal is received from the traffic light switching control device 5 by the narrow area wireless unit 44 (step S <b> 13), and the traffic light switching control device 5. Is detected ("YES" in step S13), the traffic signal switching status is extracted from the received switching status notification signal, and the traffic signal switching status is displayed on the display device 46 ( Step S14). Thereby, not only the switching situation of the traffic signal waiting for the signal but also the switching situation of the surrounding traffic lights can be notified to the walking user.

  By the way, in the above configuration, in the traffic light switching control device 5, when the switching request signal is received from the portable information terminal 4 when the switching request signal is received from the in-vehicle navigation device 2, as shown in FIG. When a signal waiting notification signal indicating that a person is waiting for a signal is transmitted to the in-vehicle navigation device 2 and the reception of the signal waiting notification signal from the traffic light switching control device 5 is detected in the in-vehicle navigation device 2, FIG. As shown in b), a display message indicating that a person is waiting for a signal (for example, “please note that there is a pedestrian”) is displayed on the display device 30 (see Q in FIG. 8). Thereby, it can inform the user who is driving the vehicle that the person is waiting for the signal, and can call attention to the pedestrian.

  On the contrary, in the traffic light switching control device 5, when the switching request signal is received from the in-vehicle navigation device 2 when the switching request signal is received from the portable information terminal 4, FIG. 7 also shows. As described above, when the signal waiting notification signal indicating that the vehicle is waiting for the signal is transmitted to the portable information terminal 4 and the reception of the signal waiting notification signal from the traffic light switching control device 5 is detected in the portable information terminal 4, the vehicle A display message indicating that the signal is waiting is displayed on the display device 46. Accordingly, it is possible to notify the user who is walking that the vehicle is waiting for a signal and to call attention to the vehicle.

  In addition, as described above, the traffic signal switching control device 5 receives the switching request signal from the in-vehicle navigation device 2 and also receives the switching request signal from the portable information terminal 4 to switch the traffic signal from the vehicle and the person waiting for the signal. The configuration corresponding to the request is described. However, the configuration in which the traffic light switching control device 5 accepts only the switching request signal from the in-vehicle navigation device 2 and corresponds only to the traffic signal switching request from the vehicle waiting for the signal. Alternatively, the traffic signal switching control device 5 may accept only the switching request signal from the portable information terminal 4 so as to respond only to the traffic signal switching request from the person waiting for the signal.

  As described above, according to the present embodiment, in the traffic control system 1, the reception status of the switching request signal actually transmitted from the in-vehicle navigation device 2 or the portable information terminal 4 and received by the traffic light switching control device 5. Based on the above, the traffic signal switching control is performed so that the vehicle-mounted navigation device 2 or the portable information terminal 4 that has transmitted the switching request signal is allowed to pass through the intersection. Unlike conventional systems that perform control, it is possible to appropriately perform dynamic switching control of traffic lights according to actual traffic volume by performing switching control of traffic lights based on switching request signals actually transmitted and received Can do.

  Even if the condition for the switching control is not satisfied, when the switching control timing set in advance is reached, the in-vehicle navigation device 2 and the portable information terminal 4 are allowed to pass through the intersection in preference to the switching control timing. Thus, since it is configured to perform the switching control of the traffic light, it is possible to prevent a signal waiting time of a vehicle or a person waiting for a signal from being prolonged insignificantly.

The present invention is not limited to the above-described embodiment, and can be modified or expanded as follows.
The in-vehicle device is not limited to the in-vehicle navigation device, and may be configured from a dedicated device having the above-described function. The portable terminal is not limited to the portable information terminal, and may be constituted by a dedicated terminal having the above-described function or a known portable telephone. When a plurality of traffic signals are densely arranged, a configuration may be adopted in which switching request signals transmitted from the in-vehicle navigation device or the portable information terminal are simultaneously received by the plurality of traffic signal switching control devices.

  If the in-vehicle navigation device or the portable information terminal transmits the switching request signal multiple times at predetermined intervals, and the traffic signal switching control device is configured to accept the switching request signal from the same in-vehicle navigation device or portable information terminal multiple times, the signal Even when the number of waiting vehicles and the number of people are small, it is possible to prevent a signal waiting time of vehicles and people waiting for signals from being prolonged unnecessarily.

As a weighting score, for example, a high score is set for an emergency vehicle or a vehicle in a specific area, and a low score is set for a vehicle other than an emergency vehicle (general) or a vehicle in a region excluding a specific area. With this configuration, it is possible to perform (advantageously) switching control of a traffic light with priority given to an emergency vehicle or a vehicle in a specific area. Further, the weighting points may be differentiated according to other factors such as the user's driving history (for example, whether the driver is a so-called excellent driver) or the user's age (for example, whether the driver is an elderly person).
The configuration may be such that the switching status notification signal and the signal waiting notification signal transmitted from the traffic light switching control device are omitted.
