Abstract

PROBLEM TO BE SOLVED: To perform smooth and efficient traffic guidance in an alternating traffic section. A passing vehicle detection sensor 22A provided at one end of an alternating traffic section detects the approach of a vehicle V1 and adds 1 to the number of vehicles in the section (S11). When the passing vehicle detection sensor 22B provided at the other end of the alternating traffic section detects the exit of the vehicle V1 and subtracts 1 from the number of vehicles in the section (S12a), the number of vehicles in the section becomes "0" and the traffic light 25B is turned on. It is possible to switch from the entry prohibited state to the entry permitted state (S13). Further, when the vehicle V1 goes out on the connecting road, the passing vehicle detection sensor 22C detects it and subtracts 1 from the number of vehicles in the section (S12b). The guide terminal device 30 is operated to subtract 1 from the number of vehicles in the section (S12c). Therefore, the subtraction of the number of vehicles in the section occurs earlier than the case of exiting from the other end of the alternating traffic section, and the traffic light 25B can be switched earlier.

  Hereinafter, preferred embodiments of a traffic guidance system and method according to the present invention will be described in detail with reference to the accompanying drawings.

<Concept of traffic guidance system according to the embodiment>
First, the concept of the traffic guidance system according to the present embodiment will be described. FIG. 1 is an explanatory view for explaining the concept of the traffic guidance system according to the present embodiment. In FIG. 1, the road construction is performed in the illustrated construction work area of a road consisting of a two-lane road with one lane on one side, and this road construction makes one lane unusable. Therefore, alternate traffic zones are provided using the remaining one lane. In FIG. 1, alternate passing sections are indicated by hatching.

  In order to control the passage of vehicles in the alternating passage section, the traffic light 25A and the passing vehicle detection sensor 22A are installed at one end of the alternating traffic section, and the traffic signal 25B and the passing vehicle detection sensor 22B are installed at the other end. doing. Further, since there is a connecting road connected in the middle of the alternate passing section, the traffic light 25C and the passing vehicle detection sensor 22C are installed in the vicinity of the alternating passing section of the connecting road. Furthermore, since there is a store adjacent to the alternating passage section, the induction member carries the induction terminal device 30 to cope with the entry and exit of the vehicle pertaining to the store.

  In the traffic guidance system shown in FIG. 1, the number of vehicles located in the alternate passage section is calculated as the number of vehicles in the section, and the passage of vehicles is controlled based on the number of vehicles in the section. Specifically, the passing vehicle detection sensor 22A and the passing vehicle detection sensor 22B detect the passage of vehicles at both ends of the alternating passage section, and when the entry of the vehicle to the alternating passage section occurs, the number of vehicles in the section is 1 The addition is performed, and when the departure of the vehicle from the alternate passage section occurs, the number of vehicles in the section is decremented by one. Then, signal switching control is performed on condition that the number of vehicles in the section is zero.

  Here, since there are connecting roads and stores in the alternate passing section, the number of vehicles in the section may increase or decrease regardless of the passage of vehicles at both ends of the alternate passing section. For example, when a vehicle entering from the end of the alternating passage section leaves the connecting road or enters a store, the number of vehicles in the section decreases without passing through the end of the alternating passage section. Similarly, when a vehicle enters an alternating passage section from a connecting road or store, the number of vehicles in the section increases without passing through the end of the alternating passage section.

  If an increase or decrease in the number of vehicles in the section occurs regardless of the passage of vehicles at both ends of the alternating traffic section, the number of vehicles in the section is corrected, and the signal of Perform switching control. Specifically, when the passing vehicle detection sensor 22C detects the passage of the vehicle, subtraction or addition of the number of vehicles in the section is performed according to the detected traveling direction of the vehicle. Moreover, about the in-out of the vehicle which concerns on a store, a guidance member operates the guidance terminal device 30, and subtracts or adds the number of vehicles in a section.

  In the case where the construction vehicle goes out of the alternate passage section to the construction work area, or when the construction vehicle enters the alternate passage section from the construction work area, the induction worker takes the induction worker terminal device 30 as in the case of the store. Operate to subtract or add the number of vehicles in the section. That is, the store or the work area is an external area adjacent to the alternate passage section, and the guiding member terminal device 30 notifies the entry and exit of the vehicle related to the external area.

  FIG. 1 (a) shows leaving on the way of the alternate passage section. First, when the traffic light 25A provided at one end of the alternating passage section enters the permission state, the vehicle V1 enters the alternating passage section. The passing vehicle detection sensor 22A detects the approach of the vehicle V1 and adds 1 to the number of vehicles in the section (S11). After that, when the vehicle V1 travels in the alternating passage section and comes out from the other end of the alternating passage section, the passing vehicle detection sensor 22B detects the exit of the vehicle V1 and subtracts one from the number of vehicles in the section (S12a). As a result, the number of vehicles in the section becomes "0", and the traffic signal 25B can be switched from the entry prohibited state to the entry permitted state (S13).

  On the other hand, when the vehicle V1 entering the alternating passage section leaves the connecting road, the passing vehicle detection sensor 22C detects the exit of the vehicle V1 and subtracts one from the number of vehicles in the section (S12b). As a result, the number of vehicles in the section becomes "0", and the traffic signal 25B can be switched from the entry prohibited state to the entry permitted state (S13). When the vehicle V1 leaves the connecting road, subtraction of the number of vehicles in the section occurs earlier than when the vehicle V1 exits from the other end of the alternate passage section, and switching of the traffic signal 25B can be performed earlier. The waiting time of the vehicle waiting on the 25B side can be shortened and efficient traffic guidance can be performed.

  Further, if the vehicle V1 entering the alternating passage section comes out of the alternating passage section by entering the store, the induction member operates the induction terminal device 30 to subtract 1 from the number of vehicles in the section (S12 c). As a result, the number of vehicles in the section becomes "0", and the traffic signal 25B can be switched from the entry prohibited state to the entry permitted state (S13). Even when the vehicle V1 goes out of the alternating passage section by entering the store etc., subtraction of the number of vehicles in the section occurs earlier than in the case of leaving the other end of the alternating passage section, and switching of the traffic light 25B is made earlier It can be carried out.

  FIG. 1 (b) shows the approach from the middle of the alternate passage section. First, when the traffic light 25A provided at one end of the alternating passage section enters the permission state, the vehicle V1 enters the alternating passage section. The passing vehicle detection sensor 22A detects the approach of the vehicle V1 and adds 1 to the number of vehicles in the section (S21). Furthermore, when the vehicle V2 enters the alternating passage section from the store by the guidance of the induction member, the induction member operates the induction terminal device 30 to add 1 to the number of vehicles in the section (S22). As a specific procedure, first, when there is a vehicle V2 that is going to enter an alternating passage section, the induction member confirms that the traveling direction of the vehicle V2 matches the current traveling direction, and the number of vehicles in the section The induction terminal device 30 is operated to add one. Thereafter, the safety member performs a safety check such as confirming the passage of the traveling vehicle, and guides the vehicle V2 to enter the alternating passage section.

  Thereafter, when the vehicle V1 travels in the alternating passage section and comes out from the other end of the alternating passage section, the passing vehicle detection sensor 22B detects the exit of the vehicle V1 and subtracts 1 from the number of vehicles in the section (S23). Furthermore, when the vehicle V2 travels in the alternate passage section and comes out from the other end of the alternate passage section, the passing vehicle detection sensor 22B detects the exit of the vehicle V2 and subtracts 1 from the number of vehicles in the section (S24). When both vehicles V1 and V2 are detected to leave, and the number of vehicles in the section becomes "0", it is possible to switch the traffic light 25B from the entry prohibition state to the entry permission state (S25).

  As described above, the traffic guidance system according to the present embodiment includes the passing vehicle detection sensor 22A and the passing vehicle detection sensor 22B installed at both ends of the alternate passing section and detecting the passage of the vehicle, and the passing vehicle detection sensor 22A and Calculates the number of vehicles in the section based on the detection result by the passing vehicle detection sensor 22B, and corrects the number of vehicles in the section when the number of vehicles in the section increases or decreases regardless of the passage of vehicles at both ends of the alternating passage Control the traffic light based on the number of vehicles in the section.

  With this configuration and control, the present invention can be applied to the case where there are vehicles coming in and out of a connecting road, a shop, and a construction work area, and the length of the alternating passage section is not limited. Therefore, it is possible to achieve smooth and efficient traffic guidance while realizing high versatility and reducing the number of personnel. In addition, when the vehicle exits in the middle of the alternate passage section, the signal can be switched early, so the waiting time of other vehicles can be shortened and efficient traffic guidance can be performed.

The functions of the unit 46a, the control mode selection unit 46b, the in-section vehicle number calculation unit 46c, and the in-section vehicle number correction unit 46d are exhibited.

  The signal control unit 46a is a control unit that controls a traffic signal included in the traffic guidance system. For example, when the traffic guidance system includes the passage management device 20A, the passage management device 20B, and the passage management device 20C as the passage management device 20, the traffic signals 25 included in the respective passage management devices 20 are to be controlled.

  In the control of the traffic light 25, the signal control unit 46a performs signal switching using any of a plurality of control modes. The plurality of control modes include a detection control mode, a time control mode, a manual control mode, and the like.

  The detection control mode is a control mode in which the traffic signal 25 is switched to the entry permission state on the condition that the stopped vehicle in the vicinity of the stop line is detected while waiting with the traffic signal 25 in the entry prohibited state. If the entry of the vehicle does not occur even if the traffic light 25 is permitted to enter, the waiting time of the other traffic light 25 is unnecessarily extended. Therefore, when the traffic volume is relatively small, the detection control mode is used to switch to the entry permission state only when there is a stopped vehicle, thereby reducing the overall waiting time and improving the vehicle traffic efficiency. be able to.

  The time control mode is a control mode that switches between the entry prohibition state and the entry permission state on the condition that time elapses. In the time control mode, the traffic signal 25 is switched to the entry permission state regardless of whether the vehicle is present near the stop line. When the traffic volume is relatively large, there is a high possibility that the vehicle may enter before the entry permission state ends even if the vehicle is not detected at a specific time. Therefore, switching the state of the traffic light 25 at a predetermined timing can reduce the overall waiting time and make the passing of the vehicle more efficient.

  The manual control mode is a control mode in which traffic guidance is performed by switching the state of the traffic light 25 based on the operation of the induction member. This manual control mode is used, for example, when an abnormality occurs in the condition of the alternate passage section or the condition of the traffic guidance system.

  The plurality of traffic lights 25 included in the traffic guidance system can individually set the control mode, and the signal control unit 46a sequentially selects the plurality of traffic lights 25 and uses the control mode set for the selected traffic lights 25. Switch the signal.

  In addition, after switching the signal for one traffic signal 25, the next traffic signal 25 is selected, but at this time, the signal control unit 46a performs the following operation on condition that the number of vehicles in the section is zero. The traffic signal 25 of is selected. As a result, when the signal control unit 46a switches any one of the traffic signals 25 from the entry prohibited state to the entry permitted state, the number of vehicles in the section is zero.

  The control mode selection unit 46 b performs processing to change the control mode of the traffic light 25 based on the passing state of the vehicle. For example, when the traffic volume is high for the traffic light 25 set in the detection control mode, it is desirable to select and change the time control mode. Similarly, for the traffic light 25 set in the time control mode, it is desirable to select and change the detection control mode when the traffic volume is small.

  Therefore, when the predetermined selection condition is satisfied, the control mode selection unit 46b selects a control mode different from the set control mode, and changes the control mode. Specifically, when the vehicle continuously enters in the detection control mode, and the “upper limit timeout” in which the entry permission state of the traffic light 25 continues to the upper limit continues a predetermined number of times, the control mode selection unit 46 b performs the time control mode It is determined that the selection condition of is satisfied. Further, while the traffic light 25 is in the entry permitted state in the time control mode, the control mode selection unit 46b selects the detection control mode when the "zero entry" where no vehicle enters does not continue a predetermined number of times. It is determined that the condition is satisfied.

  The control mode selection unit 46 b selects the control mode for each traffic light 25, that is, for each approach route of the vehicle to the alternating passage section. Further, when the restriction on the selection of the control mode is set for the specific entry route, the control mode selection unit 46b selects the control mode within the set restriction range.

  The in-section vehicle number calculation unit 46c is a processing unit that calculates the number of vehicles located in the alternating passage section as the in-section vehicle number based on the passage of vehicles at both ends of the alternating passage section. Specifically, using the detection result of the passage of the vehicle notified from the passage management device 20A and the passage management device 20B, when the entry of the vehicle to the alternating passage section occurs, the number of vehicles in the section is incremented by one, When the departure of the vehicle from the alternate passage section occurs, the number of vehicles in the section is decremented by one. The in-section vehicle number calculation unit 46 c stores the calculated in-section vehicle number as the in-section vehicle number data 45 b in the storage unit 45.

  The in-section vehicle number correction unit 46 d is a processing unit that corrects the in-section vehicle number when an increase or decrease in the in-section vehicle number occurs regardless of the passage of vehicles at both ends of the alternating passage section. Specifically, subtraction or addition of the number of vehicles in the section is performed according to the notified traveling direction of the vehicle, using the detection result of the passage of the vehicle notified from the passage management device 20C. Further, when the external area entry / exit data indicating the entrance / exit of the vehicle relating to the external area is received from the induction terminal device 30, the number of vehicles in the section is subtracted or added according to the external area entry / exit data. The in-section vehicle number correction unit 46 d updates the in-section vehicle number data 45 b with the corrected in-section vehicle number.

  Next, an example of the device setting data 45 a stored in the storage unit 45 shown in FIG. 8 will be described. FIG. 9 is a diagram showing an example of the device setting data 45a stored in the storage unit 45 shown in FIG. The device setting data 45a shown in FIG. 9 is data in which the selectable control mode, the selected control mode, the upper limit timeout consecutive number of times and the entry zero consecutive number of times are associated with the device ID of the passage management device 20.

  Specifically, in FIG. 9, "time control, detection control and manual control" are associated with the device ID "20A" as selectable control modes, and the control mode being selected is "detection control", It shows a state in which the upper limit timeout continuous number of times is "2". In addition, since the detection control mode is being selected, the code | symbol which shows data absence is matched with respect to the approach zero continuation frequency.

  Further, in FIG. 9, "time control, detection control and manual control" are associated with the device ID "20B" as selectable control modes, and the control mode being selected is "time control" and entry zero is continuous. It shows that the number of times is "3". In addition, since the detection control mode is being selected, the code | symbol which shows data absence is matched with respect to the upper limit timeout continuation frequency.

  Similarly, in FIG. 9, "detection control and manual control" are associated with the device ID "20C" as selectable control modes, the control mode being selected is "detection control", and the upper limit timeout continuous number is It shows a state of "0". That is, "time control" is not included in the selectable control mode of the device ID "20C", and the restriction is set in the selection of the control mode.

<Operation of traffic guidance system>
FIG. 10 is a flowchart showing the processing procedure of the signal control unit 46a in the detection control mode. The signal control unit 46a sets the initial state of the traffic light 25 to the entry prohibition state (step S101). Then, it is determined whether the traffic light 25 is selected as a control target (step S102). As a result of the determination, if it is not selected (Step S102; No), the process proceeds to Step S102 and waits until it is selected. When it is selected (step S102; Yes), the signal control unit 46a determines whether there is a stopped vehicle near the stop line based on the notification from the corresponding stop detection device 10 (step S103) . As a result of the determination, if there is no stopped vehicle (Step S103; No), the signal control unit 46a selects another traffic signal 25 as a control target (Step S114), and the process is ended.

  On the other hand, when there is a stopped vehicle (step S103; Yes), the signal control unit 46a sets the state of the traffic light 25 to the entry permission state (step S104). Subsequently, the signal control unit 46a turns on the upper limit timer and the continuous passage timer, and starts the countdown from the initial value (step S105). The initial value of the upper limit timer corresponds to the maximum length of one entry permitted state in the detection control mode. In addition, the initial value of the continuous passage timer corresponds to the minimum length of one entry permitted state in the detection control mode. When an upper limit time-out at which the upper limit timer becomes zero occurs, the entry permission state is ended even if the vehicle is present in the vicinity of the stop line, and the state is switched to the entry prohibition state. The continuous passage timer is a timer that is reset each time the vehicle passes in the detection control mode, and when the continuous passage time-out when the continuous passage timer becomes zero occurs, that is, when the passage of the vehicle is interrupted, the upper limit Regardless of the value of the timer, the entry permitted state is ended and switched to the entry prohibited state.

  Thereafter, it is determined whether or not the passage management device 20 has detected entry of a vehicle (step S106), and if entry of a vehicle is detected (step S106; Yes), the number-of-vehicles in-section calculation unit 46c determines in-section The number of vehicles is incremented by one (step S107), and the signal control unit 46a resets the continuous passage timer (step S108).

  When the entry of the vehicle is not detected (step S106; No), the signal control unit 46a determines whether or not the continuous passage time-out at which the continuous passage timer becomes zero has occurred (step S109).

  If the continuous passage timeout has not occurred (step S109; No), or if the continuous passage timer is reset (step S108), the signal control unit 46a determines whether the upper limit timeout at which the upper limit timer becomes zero has occurred. It determines (step S110). If the upper limit timeout has not occurred (Step S110; No), the signal control unit 46a proceeds to Step S106, and determines whether the approach of the vehicle has been detected.

  If the upper limit timeout has occurred (step S110; Yes), or if the continuous passage timeout has occurred (step S109; Yes), the signal control unit 46a turns off the upper limit timer and the continuous passage timer (step S111). Are switched to the entry prohibited state (step S112). Then, after passing standby processing (step S113) for waiting until the vehicle which has entered has left the alternating traffic section (step S113), the signal control unit 46a selects another traffic signal 25 as a control target (step S114) and ends the processing. Do.

  FIG. 11 is a flowchart showing the details of the passage standby process shown in FIG. When the passage standby process starts, the intra-section vehicle number correction unit 46d determines whether to enter from the external area based on whether or not external area entry / exit data indicating entry of a vehicle is received from the induction terminal device 30 (step S201). . Then, if it is determined that the vehicle has entered from the external area (step S202; Yes), the in-section vehicle number correction unit 46d performs correction to add 1 in the number of in-section vehicles (step S203).

  After step S203, or when it is determined that there is no entry from the external area (step S202; No), the intra-section vehicle number calculation unit 46c and the intra-section vehicle number correction unit 46d perform the exit determination from the alternating passage section (Step S204). Specifically, the intra-section vehicle number calculation unit 46c determines that there is a departure from the alternating passage section when any one of the passage management devices 20 detects the passage of the vehicle from the alternating passage section to the external area. In addition, when the in-section vehicle number correction unit 46 d receives external area entry / exit data indicating the exit of a vehicle from the induction terminal device 30, it determines that there is exit from the alternating passage section.

  If the in-section vehicle number calculation unit 46c or the in-section vehicle number correction unit 46d determines that there is a departure from the alternate passage section (step S205; Yes), the in-section vehicle number calculation unit 46c or the in-section vehicle number correction unit 46d The number of vehicles in the section is decremented by 1 (step S206).

  After step S206, or when it is determined that there is no exit from the alternating passage section (step S205; No), the signal control unit 46a determines whether the number of vehicles in the section is zero (step S207). If the number of vehicles in a section is not zero (Step S207; No), it will shift to Step S201 and will judge the approach from the exterior field. On the other hand, if the number of vehicles in the section is zero (step S207; Yes), the signal control unit 46a ends the process.

  FIG. 12 is a flowchart showing the processing procedure of the signal control unit 46a in the time control mode. The signal control unit 46a sets the initial state of the traffic light 25 to the entry prohibition state (step S301). Then, the signal control unit 46a determines whether the traffic light 25 is selected as a control target (step S302). As a result of the determination, if it is not selected (step S302; No), the process proceeds to step S302 and waits until it is selected. When it is selected (step S302; Yes), the signal control unit 46a switches the traffic light 25 to the entry permission state (step S303), turns on the entry permission timer, and starts the countdown from the initial value (step S304) . The initial value of the entry permission timer corresponds to the length of one entry permission state in the time control mode. When an entry permission timeout occurs in which the entry permission timer becomes zero, the entry permission state is ended even if there is a vehicle near the stop line, and the entry prohibition state is switched to the entry prohibited state.

  Thereafter, it is determined whether or not the passage management device 20 has detected entry of a vehicle (step S305), and if entry of a vehicle is detected (step S305; Yes), the intra-section vehicle number calculation unit 46c determines that the section The number of vehicles is incremented by one (step S306).

  After step S306, or when the entry of the vehicle is not detected (step S305; No), the signal control unit 46a determines whether or not the entry permission time out in which the entry permission timer becomes zero has occurred (step S307). ).

  If the entry permission timeout has not occurred (step S307; No), the signal control unit 46a proceeds to step S305, and determines whether the entry of the vehicle has been detected.

  When the entry permission timeout occurs (step S307; Yes), the signal control unit 46a turns off the entry permission timer (step S308), and switches the traffic light 25 to the entry prohibition state (step S309). Then, after passing standby processing (step S310), which waits until the vehicle which has entered has left the alternating traffic section (step S310), the signal control unit 46a selects another traffic light 25 as a control target (step S311), and ends the processing. Do. The passage standby process may be performed according to the process procedure shown in FIG.

  Next, change of control mode will be described. FIG. 13 is a flowchart showing a processing procedure according to change from the time control mode. The control mode selection unit 46b refers to the device setting data 45a for the traffic signal 25 operating in the time control mode (step S401), and determines whether the detection control mode can be selected (step S402).

  If the detection control mode is selectable (step S402; Yes), the control mode selection unit 46b determines whether the number of consecutive entry zeros exceeds a predetermined value (step S403). Then, if the number of consecutive entry zeroes exceeds the predetermined value (step S403; Yes), the control mode selection unit 46b selects the detection control mode and changes the control mode (step S404). After step S404, or when the detection control mode is not selectable (step 402; No), or when the number of consecutive entry zeros does not exceed the predetermined value (step S403; No), the process ends.

  FIG. 14 is a flowchart showing a processing procedure according to the change from the detection control mode. The control mode selection unit 46b refers to the device setting data 45a for the traffic signal 25 operating in the detection control mode (step S501), and determines whether the time control mode can be selected (step S502).

  If the time control mode is selectable (step S502; Yes), the control mode selection unit 46b determines whether the number of consecutive upper limit timeouts exceeds a predetermined value (step S503). Then, if the number of consecutive upper limit timeouts exceeds the predetermined value (step S503; Yes), the control mode selection unit 46b selects the time control mode and changes the control mode (step S504). After step S504, or when the time control mode is not selectable (step S502; No), or when the number of consecutive upper limit timeouts does not exceed the predetermined value (step S503; No), the process ends.

  As described above, according to the present embodiment, the passage management device 20 is installed at both ends of the alternating passage section to detect the passage of the vehicle, and based on the detection result of the passing of the vehicle at both ends of the alternating passage section Calculate the number of vehicles located in the alternating section as the number of vehicles in the section, and if the number of vehicles in the section increases or decreases regardless of the passage of vehicles at both ends of the alternating section, correct the number of vehicles in the section And control the traffic light 25 based on the number of vehicles in the section.

  With this configuration and control, the present invention can be applied to the case where there are vehicles coming in and out of a connecting road, a shop, and a construction work area, and the length of the alternating passage section is not limited. Therefore, it is possible to achieve smooth and efficient traffic guidance while realizing high versatility and reducing the number of personnel. In addition, when the vehicle exits in the middle of the alternate passage section, the signal can be switched early, so the waiting time of other vehicles can be shortened and efficient traffic guidance can be performed.

  In addition, a detection control mode that switches the traffic light 25 to the entry permitted state on condition of detection of the vehicle while waiting with the traffic light 25 in the entry prohibited state, and a time control mode that switches between the entry prohibited state and the entry permitted state on the condition of elapsed time By performing selection of the control mode based on the traffic state of the vehicle, it is possible to efficiently switch and control the traffic light 25 and perform smooth traffic guidance.

  The selection of the control mode can be made for each entry route of the vehicle to the alternating passage section. In addition, when the restriction of the control mode is set for a specific entry route, the control mode is selected within the range of the set restriction.

  The present invention is not limited to the above embodiments, and can be implemented with appropriate changes in configuration and operation. For example, although the configuration in the case of selecting the control mode using the number of consecutive entry zeros and the number of consecutive upper limit timeouts as the passing state is illustrated in the above embodiment, the present invention is not limited to this. Any traffic condition can be used as the control mode selection condition.

  In the above embodiment, the case where the number of vehicles in the section is increased or decreased based on the external area entry and exit data notified from the induction staff terminal device 30 is described as an example, but the section is based on the external area entry and exit data The number of inner vehicles may be resettable. That is, when the induction member confirms that the vehicle is not present in the alternating passage section and performs a predetermined operation, the external member entry / exit data for which the number of vehicles in the section is reset is sent from the induction terminal device 30 to the management device 40 By transmitting, the state of the traffic light 25 is made switchable.

  In the above embodiment, the upper limit timer is turned on at the start of control in the detection control mode. For this reason, regardless of whether the vehicle is on standby in the other entry route, it becomes entry prohibition state with upper limit timeout, but as a modification, when stopping vehicle is detected near the stop line of the other entry route The upper timer may be turned on. In such a configuration, as long as vehicles enter continuously and there is no waiting vehicle in another approach route, the entry permission state can be continued.

  As described above, the traffic guidance system and traffic guidance method according to the present invention are suitable for smooth and efficient traffic guidance in alternating traffic sections.
