Description

  The present invention relates to a traffic control device and a traffic control system for controlling a passable state at an intersection where a plurality of vehicles intersect.

At an intersection where the traveling lines of the host vehicle and the partner vehicle intersect, either the host vehicle or the partner vehicle travels preferentially, so that a smooth traffic state is maintained. Conventionally, priorities at such intersections have been determined by providing traffic lights at the intersections or providing certain traffic laws. In recent years, a technique has been disclosed in which priority is set between the host vehicle and the opponent vehicle, and the priority order at the intersection of the vehicles is determined based on the priority. As an example, there is a traffic control system disclosed in JP-A-11-110893. This traffic control system exchanges information about priority between the vehicle and the other vehicle when the vehicle and the other vehicle are about to enter the intersection, and which vehicle is based on the priority of both vehicles. Is to determine whether or not is prioritized.
JP-A-11-110893

  However, in the traffic control system disclosed in Patent Document 1, the priority is determined based on the positional relationship between both vehicles, the type of the vehicle, the waiting time just before entering the intersection, and the like. For this reason, there is a problem that unfairness may be increased between vehicles, such that a predetermined vehicle is always prioritized and a predetermined vehicle is always non-prioritized.

  Therefore, an object of the present invention is to provide a traffic control device and a traffic control system capable of enhancing a sense of fairness among vehicles when determining priorities of a plurality of vehicles at an intersection.

  In the traffic control device according to the present invention, priority points are compared with the counterpart vehicle, and the priority at the intersection is determined based on the comparison result. Here, in calculating the priority point, the past traveling history of the host vehicle is referred to. Therefore, for example, a vehicle having a large number of times of giving way in the past can be easily prioritized, so that a sense of fairness among the vehicles can be enhanced.

  The past travel history may be at least one of a priority history at an intersection that has passed in the past, a traffic law compliance history, and a passage waiting time history at an intersection that has passed in the past.

As a result, the fairness between the vehicles can be further increased. Here, the priority point can be subtracted when priority is given at the intersection, and the priority point can be added when priority is given to the intersection.

  In addition, the vehicle further includes priority selection means for the occupant to select a priority ratio at the intersection, and the priority determination means is the priority of the host vehicle relative to the opponent vehicle based on the priority point comparison result and the priority selected by the occupant. It can be set as the aspect which judges.

  In this way, by providing the priority level selection means, the usage method of the priority points can be selected depending on whether the occupant (driver) is in a hurry or not, so the driver effectively uses the priority points according to his / her own intention. Will be able to.

Priority points are calculated with reference to the travel history.

  In the traffic control system according to the present invention, priority points are compared among the vehicles, and the priority at the intersection is determined based on the comparison result. Here, in calculating the priority point, the past traveling history of the host vehicle is referred to. Accordingly, since priority points according to past travel histories are calculated, it is possible to improve fairness among the vehicles.

  Here, the total value of the traffic signal provided at the intersection, the traffic signal control means for controlling the traffic signal based on the priority points in the plurality of vehicles, and the priority points of the vehicles waiting for the signals in each lane at the intersection And a priority total value calculating means for calculating the traffic light, and the traffic light control means can control the traffic light based on the total value of the priority points in each lane.

  In this way, when a plurality of vehicles are lined up at an intersection where a traffic signal is provided at the intersection, by controlling the traffic signal based on the total value of the priority points of each vehicle, The traffic light can be controlled with a high feeling.

  According to the vehicle traffic control device and the traffic control system according to the present invention, it is possible to enhance a sense of fairness among vehicles when determining priorities of a plurality of vehicles at an intersection.

The receiving means 21 is connected to the priority point comparison / determination unit 15 in the ECU 1 and outputs the received priority point to the priority point comparison / determination unit 15. The navigation device 22 includes a GPS antenna and own vehicle position detection means, receives position information output from a satellite or the like by the GPS antenna, and refers to a map stored in the own vehicle position detection means. The position of the own vehicle is detected. The navigation device 22 is connected to the intersection determination unit 11 in the ECU 1 and outputs the detected position information of the own vehicle to the intersection determination unit 11 together with map information in the vicinity of the own vehicle.

  The speed sensor 23 is attached to the wheel, for example, and detects the speed of the host vehicle. The speed sensor 23 is connected to the traveling state determination unit 12 in the ECU 1 and outputs the detected speed information of the host vehicle to the traveling state determination unit 12. The transmission means 24 is provided, for example, on the vehicle body of the vehicle, and outputs the priority point calculated by the priority point calculation unit 13 to, for example, another vehicle.

  The priority point information input means 25 is a means for inputting information related to priority points such as attributes of vehicles and drivers. The priority point information input means 25 is connected to the priority point storage unit 14 in the ECU 1 and outputs the input priority point information to the priority point storage unit 14. The priority point information here includes driver information such as whether the driver is a beginner or an elderly person, vehicle information such as whether the vehicle is an emergency vehicle, and driver history information such as whether the driver has a violation history. It is.

  The display part 31 consists of the monitor provided, for example in the instrument panel part of the vehicle, and is provided with a priority display lamp and a non-priority display lamp. Based on the information output from the passage permission unit 16, the display unit 31 lights either the priority indicator lamp or the non-priority indicator lamp. The brake system 32 includes an automatic brake that brakes the vehicle in a state unrelated to the driver's intention. The brake system 32 is connected to the passage permission unit 16, and when priority information is output from the passage permission unit 16, the operation of the automatic brake is prohibited, and when non-priority information is output, the automatic brake is operated. Make it possible.

  In the intersection determination unit 11 in the ECU 1, based on the map information output from the navigation device 22 and the position information of the own vehicle, whether or not there is an intersection where the traveling lines of a plurality of vehicles intersect each other in front of the traveling line of the own vehicle. Judging. The intersection determination unit 11 outputs a determination result as to whether or not there is an intersection to the priority point calculation unit 13. The traveling state determination unit 12 determines whether the host vehicle is in a stopped state based on the speed information output from the speed sensor 23. The traveling state determination unit 12 outputs a determination result as to whether or not the vehicle is in a stopped state to the priority point calculation unit 13.

  The priority point calculation unit 13 outputs from the priority point storage unit 14 whether or not the intersection is output from the intersection determination unit 11 and whether or not the stop state is output from the traveling state determination unit 12. The priority point calculation unit 13 that calculates priority points based on the priority points outputs the calculated priority points to the priority point storage unit 14 and the priority point comparison determination unit 15. The priority point calculation unit 13 calculates a priority point using past traffic regulations as to whether the vehicle has temporarily stopped at an intersection as a past travel history.

  The priority point storage unit 14 stores in advance priority points determined based on the priority information input from the priority point information input means 25. If the priority calculated by the priority point calculation unit 13 is output from the priority point calculation unit 13, the priority point is updated and stored each time. The priority point storage unit 14 stores priority points calculated using a history of traffic regulation compliance, which is a past travel history. Therefore, the priority point storage unit 14 serves as a travel history storage unit of the present invention. Further, the priority point storage unit 14 outputs the stored priority points to the priority point calculation unit 13.

The passage permission unit 16 controls priority / non-priority display on the display unit 31 and operation / prohibition of automatic braking in the brake system 32 based on the own vehicle priority information output from the priority point comparison determination unit 15. .

  The traffic control device according to this embodiment having the above configuration is mounted on each of a plurality of vehicles, and the traffic control system of the present invention is configured by the traffic control devices mounted on the plurality of vehicles.

  Next, the control procedure of the traffic control device in the traffic control system according to the present embodiment will be described. In the traffic control device (traffic control system) according to the present embodiment, priority points are used to determine the priority order when a plurality of vehicles pass through an intersection. In this priority point, an upper limit value and a lower limit value are determined, and addition / subtraction based on past driving history is performed. Here, an example of a priority point adjustment procedure will be described first. The initial value of the priority point before the priority point is adjusted is determined by the priority point information input from the priority point information input unit 25. The priority point information includes driver information, vehicle information, and driver history information.

  Among these, as the driver information, when the driver is a beginner or an elderly person, a higher priority point is set as an initial value than when the driver is another person. Further, as vehicle information, when the vehicle is an emergency vehicle such as an ambulance, a high priority point is always set for the opponent vehicle without performing addition / subtraction described later. Further, when the driver has a violation history as the driver history information, a low priority point is set according to the degree of violation and the number of violations.

  Here, a procedure for adjusting the priority point will be described. FIG. 2 is a flowchart showing a procedure for adjusting priority points.

  As shown in FIG. 2, the ECU 1 in the traffic control device determines whether there is an intersection ahead of the host vehicle by referring to the position information and map information of the host vehicle output from the navigation device 22 ( S1). As a result, when there is no intersection ahead, the process returns to step S1 and the control is continued until there is an intersection. On the other hand, if it is determined that there is an intersection, it is determined whether or not the own vehicle has stopped at the intersection (S2). Whether or not the vehicle has stopped at the intersection is determined based on the position information and map information of the host vehicle output from the navigation device 22 and the speed information output from the speed sensor 23.

  As a result, if it is determined that the vehicle has stopped, it can be determined that safe driving has been performed, and therefore, the priority point calculation unit 13 adds points as priority points (S3). If it is determined in step S2 that the host vehicle has not stopped, it is determined whether an intersection is located behind the host vehicle (S4).

  As a result, if the intersection is not located behind, the vehicle has not yet passed the intersection, so the process returns to step S2 to determine whether or not the vehicle has stopped until it passes the intersection. If it is determined that the intersection is located behind, the host vehicle has passed without stopping at the intersection. In this case, since it can be determined that safe driving is not being performed, the priority point calculation unit 13 subtracts the priority point (S5).

  Thus, after the priority point is added (S3) or subtracted (S5) in the priority point calculation unit 13, the upper limit value of the priority point and the priority point are set so that the priority point does not exceed the upper limit value or the lower limit value. The lower limit value is limited (S6). In this way, priority points are calculated. The calculated priority points are output from the priority point calculation unit 13 to the priority point storage unit 14. In the priority point storage unit 14, the priority points calculated by the priority point calculation unit 13 are stored and used as priority points of the own vehicle when the traffic control is performed.

  Here, as past driving history, it is determined whether or not traffic laws and regulations are observed depending on whether or not there is a temporary stop at an intersection. Then, priority points are added when traffic laws are observed by pausing at intersections, and priority points are subtracted when traffic laws are not observed without pausing at intersections. ing. In this way, priority points are increased by complying with traffic laws in the past driving history, and priority points are decreased by not performing safe driving, so it is possible to increase fairness among vehicles. .

  Here, the priority points are adjusted depending on whether or not the vehicle has been temporarily stopped at the intersection in the past.For example, the priority points can be adjusted depending on the number of times the vehicle has been given to other vehicles at the intersection in the past. It can also be done.

  Subsequently, a control procedure of the traffic control device according to the present embodiment will be described. In the present embodiment, as shown in FIG. 3, a traffic control device is mounted on each of the host vehicle M1 and the counterpart vehicle M2, and a traffic control system is constructed by these traffic control devices. When these own vehicle M1 and partner vehicle M2 meet at intersection C, priority point information is transmitted from the respective traffic control devices in both vehicles M1 and M2, and the priority is compared with each other to control traffic. Done.

  Below, the operation | movement procedure of the traffic control apparatus in the own vehicle M1 is demonstrated. FIG. 4 is a flowchart showing an operation procedure of the traffic control device according to the present embodiment. Here, the control of the traffic control device provided in the host vehicle M1 will be described, but similar control is also performed in the opponent vehicle M2.

  As shown in FIG. 4, the traffic control device first determines whether there is an intersection in front of the host vehicle (S11). Whether or not there is an intersection ahead is determined by referring to the position information and map information of the host vehicle output from the navigation device 22. As a result, if it is determined that there is no intersection, as a result, if there is no intersection ahead, the process returns to step S1 and the control is continued until there is an intersection. On the other hand, when it is determined that there is an intersection, it is determined whether or not there is an adjacent vehicle (hereinafter referred to as “partner vehicle”) M2 at the intersection C (S12). The determination as to whether or not there is a partner vehicle M2 is made, for example, based on whether or not the partner vehicle M2 is detected by a separately provided adjacent vehicle detector.

  As a result, if it is determined that there is no opponent vehicle M2, the process returns to step S1 and continues until there is an intersection. On the other hand, if it is determined that there is a partner vehicle M2, the priority point calculation unit 13 calculates the priority point of the current host vehicle calculated by the flow shown in FIG. 2 and stored in the priority point storage unit 14. The data is output to the transmission unit 24 and the priority point comparison determination unit 15. Then, the transmission means 24 transmits the priority point information output from the priority point calculation unit 13 to the opponent vehicle M2 (S13).

  At the same time, the partner vehicle M2 transmits the priority point of the partner vehicle to the host vehicle M1. In the host vehicle M1, the priority point information output from the opponent vehicle M2 is received by the receiving means 21 (S14). The receiving means 21 outputs the received priority points to the priority point comparison / determination unit 15.

  The priority point comparison / determination unit 15 compares the priority point of the host vehicle M1 output from the priority point calculation unit 13 and the priority point of the opponent vehicle M2 output from the receiving means 21, and both the vehicles M1, M2 are compared. Are compared (S15). It is judged from the comparison result whether the priority of the own vehicle M1 is high (S16).

  As a result, when it is determined that the priority of the host vehicle M1 is not high, it is determined that the host vehicle M1 has a lower priority than the partner vehicle M2 when entering the intersection C. As a result of this determination, the priority point comparison determination unit 15 outputs priority information indicating that the host vehicle is not prioritized to the passage permission unit 16. The passage permission unit 16 to which the non-priority information is output turns on the non-priority indicator lamp on the display unit 31 (S17) and does not prohibit the operation of the automatic brake in the brake system 32. Thus, the driver is prompted to drive so that the own vehicle M1 does not enter the intersection C before the opponent vehicle M2.

  On the other hand, if it is determined in step S16 that the priority of the host vehicle M1 is high, the host vehicle M1 is determined to have priority over the opponent vehicle M2 when entering the intersection C. Based on this determination, the priority point comparison determination unit 15 outputs the vehicle priority information indicating that the vehicle is wired to the passage permission unit 16. In the passage permission unit 16 to which the priority information is output, the priority indicator lamp is turned on on the display unit 31 (S18), and the operation of the automatic brake in the brake system 32 is prohibited. Thus, the driver is prompted to drive so that the host vehicle M1 enters the intersection C before the partner vehicle M2.

  Thus, in the traffic control system according to the present embodiment, the priority order for the approach of the vehicles M1 and M2 to the intersection C is determined by comparing the priority points between the traffic control devices mounted on the vehicles. is doing. Since these priority points are set in consideration of the past driving history in each vehicle, it is possible to eliminate unfairness between the vehicles. In addition, since priority points are added when safe driving or traffic rules are observed, it is possible to encourage the driver to comply with safe driving or traffic rules.

  Next, a second embodiment of the present invention will be described. FIG. 5 is a block configuration diagram of a traffic control device according to the second embodiment of the present invention. The traffic control device according to the present embodiment is mainly different from the traffic control device described in the first embodiment in that priority mode selection means 26 that is priority degree selection means is provided. .

  The priority mode selection means 26 provided in the traffic control device in the present embodiment is provided, for example, in an instrument panel portion of a vehicle that can be reached by a driver who is driving, and a priority mode that increases priority at an intersection and a lower priority. It is possible to switch between non-priority modes. By switching between these priority modes / non-priority modes, the priority degree is changed. The priority mode selection unit 26 is connected to the priority point calculation unit 13 and outputs priority / non-priority mode information to the priority point calculation unit 13.

  The priority point calculation unit 13 calculates priority points by adding priority / non-priority mode information to the priority point information stored in the priority point storage unit 14, and calculates a priority point comparison determination unit 15. And output to the priority point storage unit 14. Further, the priority point calculation unit 13 refers to the priority history at the intersection in addition to the traffic rule compliance history as the past travel history. About another point, it has the structure similar to said 1st embodiment.

  A control procedure of the traffic control device in the traffic control system according to the present embodiment having the above configuration will be described. Here, as in the first embodiment, as shown in FIG. 3, when the host vehicle M1 and the partner vehicle M2 meet at the intersection C, priority is given from the respective traffic control devices in both the vehicles M1 and M2. A case where traffic control is performed by transmitting point information and comparing priorities with each other will be described. FIG. 6 is a flowchart showing a control procedure of the traffic control device according to the present embodiment.

  As shown in FIG. 6, in the traffic control device according to the present embodiment, as in the first embodiment, first, it is determined whether or not there is an intersection in front of the host vehicle M1 (S21), and there is no intersection. If it is determined, the control is terminated. If it is determined that there is an intersection ahead, it is determined whether there is a partner vehicle M2 (S22).

  As a result, when it is determined that there is no partner vehicle M2, the non-priority indicator lamp in which the host vehicle is non-prioritized is turned on with respect to the display unit 31 by the control of the passage permission unit 16 (S23). Thereafter, it is determined whether or not the vehicle has complied with the rules, for example, whether the vehicle has temporarily stopped at a position before the intersection (S24). As a result, when observing a rule such as temporary stop is neglected, the priority point calculation unit 13 subtracts 3 priority points (S25) and stores them in the priority point storage unit 14 (S42). Further, when rule compliance, for example, temporary suspension is performed, priority points are stored in the priority point storage unit 14 without subtraction of priority points (S42).

  If it is determined in step S22 that there is another vehicle M2, the priority point calculation unit 13 reads the priority points stored in the priority point storage unit 14 (S26). Then, the priority point calculation unit 13 reads the priority mode or non-priority mode selected by the priority mode selection unit 26 (S27). Subsequently, the priority point calculation unit 13 compares the priority points of the host vehicle M1 based on the priority point read from the priority point storage unit 14 and the priority / non-priority mode read from the priority mode selection unit 26. The calculation point is calculated by calculation (S28).

  Specifically, for example, when the non-priority mode is selected, the priority point calculation unit 13 subtracts a predetermined number of points from the priority points stored in the priority point storage unit 14. Is used as a comparison point. Here, in calculating the priority point, the priority point calculation unit 13 refers to the priority / non-priority mode selected by the driver. The driver can set priority / non-priority at the intersection when driving the host vehicle M1. When the priority mode is set, the priority at the intersection is increased, but the priority points stored in the priority point storage unit 14 are decreased.

  On the other hand, when the non-priority mode is set, the priority at the intersection is lowered, but the priority stored in the priority point storage unit 14 can be increased. Therefore, when the state is not so rushed, it is possible to store without using priority points by selecting the non-priority mode. If you are in a hurry, you can increase the possibility that you can pass through the intersection preferentially by selecting the priority mode.

  After the comparison points are calculated in this way, communication is performed between the host vehicle M1 and the partner vehicle M2 (S29), and the priority points of both vehicles are transmitted to the respective vehicles. In the host vehicle M1, the transmission unit 24 transmits the priority point information of the host vehicle M1 to the partner vehicle M2, and the receiver unit 21 receives the priority point of the partner vehicle M2 transmitted from the partner vehicle M2.

  When communication with the partner vehicle is thus performed, the priority point comparison determination unit 15 compares the priority point of the host vehicle M1 with the priority point of the partner vehicle M2 (S30), and the priority point of the host vehicle M1. It is determined whether or not is high (S31). As a result, when it is determined that the priority point of the host vehicle M1 is high, the priority indicator lamp that displays that the host vehicle is prioritized is displayed on the display unit 31 under the control of the passage permission unit 16 (S32). At the same time, the operation of the automatic brake in the brake system 32 is prohibited. Then, the priority point calculation unit 13 determines whether or not the priority mode has been selected by the priority mode selection unit 26 (S33).

  As a result, when the priority mode is selected, the priority point calculation unit 13 subtracts two points from the priority points stored in the priority point storage unit 14 (S34). When the priority mode is not selected, the own vehicle M1 is prioritized over the opponent vehicle M2, and the priority point is subtracted, but the priority mode is not selected. Lower than if priority mode was selected. Specifically, the priority point stored in the priority point storage unit 14 is subtracted by 1 point (S35).

  When the priority point is subtracted in step S34 or S35 in this way, the priority point calculation unit 13 stores the subtracted priority point in the priority point storage unit 14 (S42), and the priority point storage unit 14 Update the priority points stored in. Thereafter, the control is terminated.

  Further, when it is determined in step S31 that the priority of the host vehicle M1 is low, a non-priority indicator lamp that displays that the host vehicle is not prioritized is displayed on the display unit 31 under the control of the passage permission unit 16. Along with (S36), the operation of the automatic brake in the brake system 32 is not prohibited. Then, the priority point calculation unit 13 determines whether or not the own vehicle M1 complies with the priority (S37). The determination as to whether or not the priority is observed is made based on position information and speed information output from the navigation device 22 and the speed sensor 23.

  As a result of determining whether or not the priority is observed, if it is determined that the priority is observed, the priority point calculation unit 13 determines whether or not the non-priority mode has been selected (S38). As a result, when it is determined that the non-priority mode has been selected, two priority points stored in the priority point storage unit 14 are added (S39). If the non-priority mode is not selected, the priority point stored in the priority point storage unit 14 is added by 1 point (S40).

  Furthermore, when it is determined in step S37 that the priority is not observed, the priority point stored in the priority point storage unit 14 is subtracted by 4 points. Thus, when priority points are added or subtracted in any of steps S39 to S41, and priority points are subtracted, the priority point calculation unit 13 stores the subtracted priority points in the priority point storage unit 14. The priority points stored in the priority point storage unit 14 are updated (S42). Thereafter, the control is terminated.

  As described above, in the traffic control device according to the present embodiment, the driver can set the priority / non-priority mode and adjust the priority points according to the use status of the priority / non-priority mode at the intersection. Therefore, the driver can select the non-priority mode and add the priority points when the situation is not in a hurry, and can quickly pass through the intersection as the priority mode when the situation is in a hurry. Further, if the priority mode is used a lot, the priority point is reduced accordingly, and conversely if the non-priority mode is used a lot, the priority point can be stored. Therefore, a sense of fairness among the vehicles can be enhanced.

  In each of the above embodiments, the priority point calculation unit and the priority point comparison unit are mounted on the vehicle. However, as shown in FIG. 7, each of the priority point determination devices 40 installed in the vicinity of an intersection, for example, The priority point of the vehicle can be calculated and the priority can be determined. In this case, the host vehicle M1 and the partner vehicle M2 transmit the priority point information of the host vehicle to the priority point determination device 40, respectively. The priority point determination device 40 compares the priority points transmitted from both the vehicles M1 and M2, determines which vehicle is prioritized, and transmits the result to each of the vehicles M1 and M2. You can also

  Furthermore, in the above-described embodiment, priority / non-priority display in the vehicle and operation of the brake system are performed. As shown in FIG. 8, for example, when traffic lights S1 and S2 are provided at an intersection C, It can also be set as the aspect which controls signal S1, S2 according to the priority / non-priority of the own vehicle M1 and the other party vehicle M2 in the intersection C.

  In the case of this aspect, a traffic signal control device 50 that controls red / blue traffic lights is provided in the vicinity of the intersection C. To the traffic signal control device 50, priority point information in the first vehicle M11 and priority point information in the second vehicle M21 are transmitted. The traffic light control device 50 controls the traffic light based on the priority point information transmitted from the first vehicle M11 and the second vehicle M21.

  Specifically, when the priority point transmitted from the first vehicle M11 is higher than the priority point output from the second vehicle M21, the first traffic light S1 is turned blue and the first vehicle M11 passes. Is permitted, and the second traffic light S2 is turned red, and the passage of the second vehicle M21 is not permitted. On the contrary, when the priority point transmitted from the second vehicle M21 is higher than the priority point output from the first vehicle M11, the second traffic light S2 is blue and the passage of the second vehicle M21 is permitted. At the same time, the first traffic light S1 is turned red and the passage of the first vehicle M11 is not permitted. Thus, in this aspect, the traffic light can be controlled so as to determine the order of the vehicles passing through the intersection based on the priority points of the vehicles passing through the intersection. Therefore, it is possible to control a traffic signal having a high sense of fairness among a plurality of vehicles.

  Thus, even when a plurality of vehicles try to enter in a state where they are adjacent to each other, the traffic light can be controlled based on the priority points of the vehicles, so that a sense of fairness among the plurality of vehicles can be enhanced.

  Furthermore, as shown in FIG. 9, when a plurality of vehicles M11 to M13, M21, and M22 are waiting for a signal in each lane at an intersection C, based on the total priority points of the vehicles waiting for the signal in each lane. Thus, the traffic lights S1 and S2 can be controlled. In the example shown in FIG. 9, three vehicles M11 to M13 are arranged in one same lane, and two vehicles M21 and M22 are arranged in another adjacent one lane. Each of these vehicles M11 to M13, M21, and M22 outputs the priority point of each vehicle to the traffic signal controller 50. The traffic signal controller 50 calculates the total value of the priority points of each vehicle for each lane.

  Specifically, the total value of priority points (hereinafter referred to as “first total value”) T1 of the vehicles M11 to M13 and the total value of priority points of the vehicles M21 and M22 (hereinafter referred to as “second total value”). T2 is calculated. Then, the first total value T1 and the second total value T2 are compared. As a result, when the first total value T1 is larger, the first traffic light S1 is blue, the passage of the intersections C of the vehicles M11 to M13 in one lane is permitted, and the second traffic light S2 is red. The intersection of each of the vehicles M21 and M22 in the other lane is not permitted. Further, when the second total value T2 is larger than the first total value T1, the second traffic light S2 is blue to permit the passage of the vehicles M21 and M22 in another lane, and the first traffic light S1 is In red, the passage of the vehicles M11 to M13 in one lane is not permitted.

  Thus, by controlling the traffic light using the total value of the priority points of the vehicles arranged in each lane, the fairness among the vehicles can be further enhanced in the traffic light used by a plurality of vehicles.
