Abstract

The present invention relates to a system and method for calming traffic at an intersection. The system for calming traffic at an intersection includes: a vehicle detecting unit for calculating the driven conditions of a vehicle being driven toward an intersection; and a control unit for controlling traffic lights if it is determined that pedestrians are in danger on the basis of the driven conditions of the vehicle calculated by the vehicle detecting unit. Thus, since various safety devices appropriate to the situation are actuated by monitoring and analyzing pedestrians and driven vehicles that cross/pass an intersection, pedestrians can actively deal with safety-related incidents at an intersection where traffic accidents involving pedestrians occur frequently, when compared to a typical regulatory suppression technique and physical traffic suppression technique for traffic safety.

도 1은 본 발명의 바람직한 실시예에 따른 횡단보도 교통 평온화 시스템의 외관을 도시한 도면으로, 횡단보도 교통 평온화 시스템이 설치된 상태가 도시되어 있다.1 is a view showing the appearance of a pedestrian crossing traffic calming system according to a preferred embodiment of the present invention, a state in which a pedestrian crossing traffic calming system is installed.

And safety induction devices such as sound output unit 152, electric sign 153, and warning light 154.
도 2는, 도 1에 도시된 횡단보도 교통 평온화 시스템의 내부 블럭도이다. 도 2에 도시된 바와 같이, 본 실시예에 따른 횡단보도 교통 평온화 시스템은, 신호등 제어기(10), 차량 신호등(21), 보행자 신호등(22), 교통신호 처리부(110), 시보 수신부(120), 조도 센서(130), 제어부(140), 안전 유도부(150), 차량 감지부(160) 및 보행자 감지부(170)를 구비한다. 그리고, 안전 유도부(150)는 조명부(151), 음향 출력부(152), 전광판(153) 및 경광등(154)을 구비한다.FIG. 2 is an internal block diagram of the crosswalk traffic calming system shown in FIG. 1. As shown in FIG. 2, the pedestrian crossing traffic calming system according to the present embodiment includes a traffic light controller 10, a vehicle traffic light 21, a pedestrian traffic light 22, a traffic signal processor 110, and a time signal receiver 120. ), An illumination sensor 130, a control unit 140, a safety induction unit 150, a vehicle detection unit 160, and a pedestrian detection unit 170. In addition, the safety induction part 150 includes an illumination part 151, an acoustic output part 152, an electric sign 153, and a warning light 154.
신호등 제어기(10)는 차량 신호등(21)과 보행자 신호등(22)의 교통신호 표시를 제어하기 위한 교통신호 제어신호를 생성한다.The traffic light controller 10 generates a traffic signal control signal for controlling the traffic signal display of the vehicle traffic light 21 and the pedestrian traffic light 22.
교통신호 처리부(110)는 신호등 제어기(10)에서 생성된 교통신호 제어신호를 제어부(140)에 전달하는 한편, 제어부(140)의 제어에 따라 교통신호 제어신호를 가공하여 차량 신호등(21)과 보행자 신호등(22)으로 각각 전달한다.The traffic signal processor 110 transmits the traffic signal control signal generated by the traffic light controller 10 to the controller 140, and processes the traffic signal control signal under the control of the controller 140 to process the traffic signal 21 and the vehicle traffic light 21. Pass each to the pedestrian traffic lights 22.
구체적으로, 교통신호 처리부(110)는 차량 신호등(21)의 황색신호 점등시간을 앞당기거나, 보행자 신호등(22)의 적색신호 점등을 연장시킬 수 있는데, 이는 모두 제어부(140)의 제어에 따라 수행된다.Specifically, the traffic signal processor 110 may advance the yellow signal lighting time of the vehicle traffic light 21 or extend the red signal lighting of the pedestrian traffic light 22, all of which are performed under the control of the controller 140. do.
시보 수신부(120)는 신호등 제어기(10)와 제어부(140)의 시각을 동기화시키기 위한 수단으로, 시보를 수신하여 제어부(140)에 전달한다.The time signal receiver 120 is a means for synchronizing the times of the traffic light controller 10 and the controller 140. The time signal receiver 120 receives the time signal and transmits the time signal to the controller 140.
이에 의해, 제어부(140)가 교통신호의 주기(Cycle), 주기길이(Cycle Length), 현시(Phase) 및 현시율(Split) 등을 산출함에 있어, 시간별, 일별, 주간별, 월별, 계절별로 변화하는 현시를 신호등 제어기(10)와 동일하게 유지시킬 수 있게 되어, 차량 신호등(21)과 보행자 신호등(22)의 동작 시점이 제어부(140)의 제어에 따른 교통신호 처리부(110)의 교통신호 제어신호 가공에 의해 흐트러지지 않는다.As a result, the control unit 140 calculates the cycle of the traffic signal (Cycle), the cycle length (Cycle Length), the present (Phase) and the present rate (Split), etc., hourly, daily, weekly, monthly, seasonal It is possible to keep the changing appearance the same as the traffic light controller 10, the operation time of the vehicle traffic light 21 and the pedestrian traffic light 22 is the traffic signal of the traffic signal processing unit 110 under the control of the controller 140 It is not disturbed by control signal processing.
차량 감지부(160)는 도 1 및 도 3에 도시된 바와 같이, 교통 신호등(21 및 22)의 주부착대에 설치되어 횡단보도 전방의 일정 구역을 레이더 방식으로 감시하여, 횡단보도를 향해 주행하는 차량의 통행을 감지하는 한편, '차량의 이동속도'와 '차량과 횡단보도 간 거리'를 산출하여 제어부(140)에 전달한다.As shown in FIGS. 1 and 3, the vehicle detecting unit 160 is installed at the main mount of the traffic lights 21 and 22 to monitor a certain area in front of the crosswalk in a radar manner and drive toward the crosswalk. While detecting the traffic of the vehicle to calculate the 'speed of the vehicle' and 'distance between the vehicle and the crosswalk' and transmits to the controller 140.
보행자 감지부(170)는, 도 1 및 도 4에 도시된 바와 같이, 횡단보도 양단에서 보행자의 진입/진출을 감시하고, 보행자의 진입/진출 상황을 제어부(140)에 전달한다.1 and 4, the pedestrian detector 170 monitors the entry / exit of the pedestrian at both ends of the crosswalk and transmits the entry / exit of the pedestrian to the controller 140.
도 1 및 도 4에는 공중 설치형의 보행자 감지부(170)를 도시하였는데, 이는 설명의 편의를 위한 일 예에 불과하다. 도로의 여건에 따라, 지상 설치형으로 대체가능함은 물론이다.1 and 4 illustrate the pedestrian sensing unit 170 of the air installation type, which is merely an example for convenience of description. Of course, depending on the road conditions, it is possible to replace the ground-mounted.
조도 센서(130)는 횡단보도 상의 조도를 측정하는데, 이는 야간 및 기상악화로 인한 시계불량을 감지하기 위함이다.The illuminance sensor 130 measures illuminance on the pedestrian crossing, in order to detect a poor vision due to bad weather and bad weather.
조명부(151)는, 도 5에 도시된 바와 같이, 조도 센서(130)에 의해 시계불량이 감지된 경우, 횡단보도를 조명하기 위한 수단으로, 제어부(140)에 의해 구동 제어된다.As illustrated in FIG. 5, the lighting unit 151 is a means for illuminating a pedestrian crossing when it is detected by the illuminance sensor 130, and is controlled by the controller 140.
조도 센서(130)에 의해 시계불량이 감지된 경우, 제어부(140)는 조명부(151)를 구동시킨다. 하지만, 제어부(140)는, 시계불량 상태에서 보행자 신호등(22)에 녹색신호가 점등된 경우에만 조명부(151)를 구동시켜, 에너지 소모를 절감시킬 수 있다.When a poor visibility is detected by the illuminance sensor 130, the controller 140 drives the lighting unit 151. However, the controller 140 may drive the lighting unit 151 only when the green signal is turned on at the pedestrian traffic light 22 in a poor visibility state, thereby reducing energy consumption.
한편, 제어부(140)는, 시계불량 상태에서 보행자 감지부(170)에 의해 횡단보도에 보행자 진입이 감지된 경우, 조명부(151)를 구동시켜 보행자의 안전을 도모할 수 있다.On the other hand, the controller 140 may drive the lighting unit 151 when the pedestrian entrance is detected by the pedestrian detection unit 170 in a poor visibility state to promote the safety of pedestrians.
다른 한편으로, 제어부(140)는, 1) 보행자 감지부(170)에 의해 보행자가 신호 대기하고 있는 것이 감지된 경우 보행자 신호등(22)의 녹색신호 점등 수 초 전에 보행자 대기구역을 조명하도록 조명부(151)를 제어하여 차량의 운전자에게 보행자의 대기상황을 인지시키고, 2) 보행자 감지부(170)에 의해 보행자 횡단이 개시된 것이 감지된 경우, 보행자 대기구역 대신 횡단보도를 조명하도록 조명부(151)를 제어하여 차량의 운전자에게 횡단보도에 보행자가 진입하였음을 명확히 인식시킬 수 있다.On the other hand, the controller 140, 1) when the pedestrian detection unit 170 detects that the pedestrian is waiting for a signal, the lighting unit (1) to illuminate the pedestrian waiting area a few seconds before the green signal of the pedestrian traffic light 22 lights up. 151 controls the driver of the vehicle to recognize the waiting condition of the pedestrian, and 2) when it is detected that the pedestrian crossing is started by the pedestrian detector 170, the lighting unit 151 is illuminated to illuminate the crosswalk instead of the pedestrian waiting area. By controlling, the driver of the vehicle can clearly recognize that the pedestrian has entered the crosswalk.
또 다른 한편으로, 시계불량 상태에서 제어부(140)는, 1) 보행자 감지부(170)에 의해 보행자가 신호 대기하고 있는 것이 감지된 경우 보행자 대기구역은 주변도로 보다 고조도로 조명하되 횡단보도는 저조도로 조명하도록 조명부(151)를 제어하고, 2) 보행자 횡단이 개시되면, 보행자 대기구역은 저조도로 조명하되 횡단보도는 고조도로 조명하도록 조명부(151)를 제어할 수 있다. 다시 말해, 제어부(140)는 상기 보행자 감시부에 의해 보행자가 신호 대기구역에 진입한 것이 감지된 경우 보행자 대기구역을 주변도로 보다 높은 조도로 조명하도록 조명부(151)을 제어한다.On the other hand, in a poor visibility state, the control unit 140, 1) when the pedestrian detection unit 170 detects that the pedestrian is waiting for a signal, the pedestrian waiting area is illuminated with higher illumination than the surrounding road, but crosswalk is low light The lighting unit 151 may be controlled to illuminate the light, and 2) when the pedestrian crossing is started, the pedestrian waiting area may control the lighting unit 151 so as to illuminate the pedestrian crossing at low light but the crosswalk may be illuminated at high illumination. In other words, when it is detected that the pedestrian enters the signal waiting area by the pedestrian monitoring unit, the controller 140 controls the lighting unit 151 to illuminate the pedestrian waiting area with higher illumination.
음향 출력부(152)는 보행자에게 각종의 음향 정보를 제공하기 위한 수단으로, 제공되는 음향 정보에는 시각 장애인을 위한 교통신호 정보 외에, 위험 경고를 위한 음향 정보가 포함된다.The sound output unit 152 is a means for providing various types of sound information to pedestrians, and the provided sound information includes sound information for danger warning in addition to traffic signal information for the visually impaired.
전광판(153)은 교통상황, 안전운전 계도 내용 등이 표시됨은 물론, 차량의 운전자에게 위험을 경고하는데 이용된다. 즉, 제어부(140)는 전광판(153)을 통해 차량의 운전자에게 "감속", "횡단보도 앞 정차" 및 "보행자 횡단 중" 등의 내용을 안내하여 위험을 경고할 수 있다.The electronic sign 153 is used to warn the driver of the vehicle of danger, as well as displaying traffic conditions and safe driving system contents. That is, the controller 140 may warn the driver of the vehicle through the electric sign 153 to warn the user of the contents such as "deceleration", "stop in front of the pedestrian crossing", and "during pedestrian crossing."
경광등(154)은 차량의 운전자와 보행자 모두에게 위험을 경고하는데 이용되는 수단으로, 제어부(154)에 의해 구동된다.The beacon 154 is a means used to warn of danger to both the driver and the pedestrian of the vehicle and is driven by the controller 154.
제어부(140)는, 차량 감지부(160)를 통해 감지되는 차량의 운행상태를 기초로 보행자가 위험하다고 판단되는 경우, 교통신호 처리부(110)를 제어하여 차량 신호등(21) 및/또는 보행자 신호등(22)의 교통신호를 변경시킨다.If it is determined that the pedestrian is dangerous based on the driving state of the vehicle detected by the vehicle detecting unit 160, the controller 140 controls the traffic signal processing unit 110 to control the vehicle traffic light 21 and / or the pedestrian traffic light. The traffic signal at 22 is changed.
또한, 위와 같이 보행자가 위험하다고 판단되는 경우, 제어부(140)는 안전 유도부(150)를 통해 운전자 및/또는 보행자에 위험을 경고할 수 있다.In addition, when it is determined that the pedestrian is dangerous as described above, the control unit 140 may warn the driver and / or the pedestrian through the safety guide unit 150.
이하에서는, 제어부(140)가 교통신호 처리부(110)를 통해 교통 신호등(21, 22)을 제어하는 과정에 대해, 도 6을 참조하여 상세히 설명한다. 도 6은, 본 발명의 다른 실시예에 따른 횡단보도 교통 평온화 방법의 설명에 제공되는 도면이다.Hereinafter, a process in which the controller 140 controls the traffic lights 21 and 22 through the traffic signal processor 110 will be described in detail with reference to FIG. 6. 6 is a view provided to explain the pedestrian crossing traffic calming method according to another embodiment of the present invention.
도 6에 도시된 바와 같이, 먼저 제어부(140)는, 차량 신호등(21)의 '황색신호 점등까지 잔여 시간(t1)'을 산출하고(S210), 차량 신호등(21)의 '황색신호 점등 유지 시간(t2)'을 산출한다(S220)., The first control unit 140, as shown in Figure 6, the lighting, the yellow signal of calculating the "yellow signal remaining time (t 1) to light up, the vehicle light (21) and (S210), the vehicle light (21) The holding time t 2 ′ is calculated (S220).
'황색신호 점등까지 잔여 시간(t1)'과 '황색신호 점등 유지 시간(t2)'은, 제어부(140)가 교통신호 처리부(110)를 통해 신호등 제어기(10)로부터 수신한 교통신호의 주기(Cycle), 주기 길이(Cycle Length), 현시(Phase) 및 현시율(Split) 등으로부터 산출가능하다.'Remaining time t 1 until the yellow signal is turned on' and 'yellow signal lighting holding time t 2 ' indicate that the control unit 140 receives the traffic signal received from the traffic light controller 10 through the traffic signal processing unit 110. It can be calculated from the cycle, the cycle length, the phase and the split.
한편, 차량 감지부(160)는, 횡단보도를 향해 주행하는 '차량의 속도(v)'와 함께 '차량과 횡단보도 간 거리(L)'를 산출한다(S230, S240). S230단계와 S240단계를 통해 산출된 '차량의 속도(v)'와 '차량과 횡단보도 간 거리(L)'은 제어부(140)에 전달된다.On the other hand, the vehicle detection unit 160 calculates the distance (L) between the vehicle and the crosswalk along with the speed (v) of the vehicle traveling toward the crosswalk (S230, S240). The 'vehicle speed v' and 'distance L between the vehicle and the crosswalk' calculated in steps S230 and S240 are transmitted to the controller 140.
제어부(140)는 '차량과 횡단보도 간 거리(L)'를 '차량의 속도(v)'로 나누어, '차량의 횡단보도 도달시간(t3 = L/v)'을 산출한다(S250).The controller 140 divides the distance L between the vehicle and the crosswalk by the speed v of the vehicle, and calculates the crosswalk arrival time t 3 = L / v of the vehicle at step S250. .
S250단계에서 산출된 '차량의 횡단보도 도달시간(t3)'이, 't1' 보다 크고, 't1 + t2' 보다 작으면(S260-Y), 제어부(140)는 차량 신호등(21)의 황색신호가 조기에 점등되도록, 교통신호 처리부(110)를 제어한다(S270).When the 'crosswalk arrival time t 3 of the vehicle' calculated in step S250 is greater than 't 1 ' and smaller than 't 1 + t 2 ' (S260-Y), the controller 140 may control the vehicle traffic light ( The traffic signal processing unit 110 is controlled so that the yellow signal at 21 is turned on early (S270).
여기서, 't1'은 S210단계에서 산출된 차량 신호등(21)의 '황색신호 점등까지 잔여 시간'이고, 't2'은 S220단계에서 산출된 차량 신호등(21)의 '황색신호 점등 유지 시간'을 의미한다.Here, 't 1 ' is the 'remaining time until the yellow signal is turned on' of the vehicle traffic light 21 calculated in step S210, 't 2 ' is the 'yellow signal lighting holding time of the vehicle traffic light 21 calculated in step S220 'Means.
"t1 < t3 < t1 + t2"인 경우는, 횡단보도를 향해 주행하는 차량이, 황색신호로 점등으로 인해 급정거를 하거나, 황색신호가 점등되었음에도 무리하게 횡단보도를 통과할 여지가 있는 경우이다.If "t 1 <t 3 <t 1 + t 2 ", the vehicle driving toward the crosswalk stops suddenly because of the yellow signal, or there is no possibility of passing the crosswalk excessively even if the yellow signal is lit. If yes.
이에 따라, "t1 < t3 < t1 + t2"인 경우에는, 차량 신호등(21)의 황색신호를 조기에 점등시켜, 횡단보도를 향해 주행하는 차량을 횡단보도 진입 전에 미리 정차시킨다.Accordingly, in the case of "t 1 <t 3 <t 1 + t 2 ", the yellow signal of the vehicle traffic light 21 is turned on early to stop the vehicle traveling toward the crosswalk before entering the crosswalk.
한편, S270단계에 의해 차량 신호등(21)의 황색신호가 조기에 점등되더라도, 황색신호의 소등 시점은 변함이 없다. 즉, S270단계에 의한 황색신호 조기 점등에 의해 해당 황색신호의 점등 시간이 길어지게 될 뿐이므로, S270단계에 의해 이후의 교통신호 체계가 흐트러지지 않는다.On the other hand, even if the yellow signal of the vehicle traffic light 21 is turned on early in step S270, the point of time when the yellow signal is turned off does not change. That is, since the lighting time of the yellow signal is only long due to the early lighting of the yellow signal at step S270, the subsequent traffic signal system is not disturbed by the step S270.
S270단계에 의한 조기 점등 시점은, 제어부(140)에 의해 결정된다. 즉, 제어부(140)가 황색신호 점등 시점을 '1초' 앞당기거나 '2초' 앞당기거나 할 수 있다.The early lighting timing by the step S270 is determined by the controller 140. That is, the controller 140 may advance the time of lighting the yellow signal by '1 second' or '2 seconds'.
조기 점등 시점을 결정함에 있어, 제어부(140)는 차량의 속도(v)를 참조할 수 있다. 구체적으로, 황색신호 점등 시점의 앞당김 정도는 차량의 속도(v)에 비례하도록 할 수 있다. 즉, 차량의 속도(v)가 클수록(차량이 빠를수록) 조기 점등 시점은 미리 결정된 시점보다 많이 앞서고, 차량의 속도(v)가 작을수록(차량이 느릴수록) 조기 점등 시점은 미리 결정된 시점보다 적게 앞서도록 구현가능하다.In determining the early turn on time, the controller 140 may refer to the speed v of the vehicle. Specifically, the degree of advancement at the time of turning on the yellow signal may be proportional to the speed v of the vehicle. In other words, the larger the speed v of the vehicle (the faster the vehicle), the earlier the timing of the early lighting is much earlier than the predetermined time point, and the smaller the speed v of the vehicle (the slower the vehicle), the earlier the timing of the early lighting time than the predetermined time point. It can be implemented to be less advanced.
S270단계 이후, 제어부(140)는 차량의 속도(v)를 기초로, '차량의 제동 소요 시간(t4)'을 산출한다(S280).After operation S270, the controller 140 calculates a braking time t 4 of the vehicle based on the speed v of the vehicle at step S280.
S280단계에서, '차량의 제동 소요 시간(t4)'은, '차량의 속도(v)'와 '차량의 제동 소요 시간(t4)' 간의 관계를 매핑한 테이블을 참조하여 산출가능하다. 이 경우, '차량의 제동 소요 시간(t4)'은 '차량의 속도(v)'에 비례하게 된다. 즉, '차량의 속도(v)'가 클수록(차량이 빠를수록) '차량의 제동 소요 시간(t4)'은 길고, '차량의 속도(v)'가 작을수록(차량이 느릴수록) '차량의 제동 소요 시간(t4)'은 짧다.In operation S280, the vehicle braking time t 4 may be calculated by referring to a table that maps a relationship between the vehicle speed v and the vehicle braking time t 4 . In this case, the braking time t 4 of the vehicle is proportional to the speed v of the vehicle. That is, the greater the speed (v) of the vehicle (the faster the vehicle), the longer the braking time (t 4 ) of the vehicle, and the smaller the speed (v) of the vehicle (the slower the vehicle) ' The braking time t 4 of the vehicle is short.
한편, S280단계에서 '차량의 속도(v)'를 기초로, '차량의 제동 소요 시간(t4)'을 산출하도록 한 것은 구현상의 일 예에 불과한 것으로, 변형이 가능하다. 예를 들어, '차량의 속도(v)' 외에 '차량의 가속도(a)'를 더 참고하여 '차량의 제동 소요 시간(t4)'을 산출하도록 구현하는 것도 가능하다.On the other hand, in step S280, based on the 'vehicle speed (v)', to calculate the 'braking time (t 4 ) of the vehicle' is only an example of implementation, it is possible to modify. For example, in addition to the vehicle speed v, the vehicle may be implemented to calculate the braking time t 4 of the vehicle by further referring to the vehicle acceleration a.
S280단계에서 산출된 '차량의 제동 소요 시간(t4)'과 't1 + t2'에 대한 차의 절대값(|t4-(t1+t2)|)이 안전계수(s) 이하이면(S290-Y), 제어부(140)는 안전 유도부(150)를 제어하여 보행자에 위험을 경고한다(S300).The absolute value of the car (| t 4- (t 1 + t 2 ) |) for the 'braking time of the vehicle (t 4 )' and 't 1 + t 2 ' calculated in step S280 is the safety factor (s). Below (S290-Y), the control unit 140 controls the safety induction unit 150 to warn the pedestrians a danger (S300).
여기서, 't1'은 S210단계에서 산출된 차량 신호등(21)의 '황색신호 점등까지 잔여 시간'이고, 't2'은 S220단계에서 산출된 차량 신호등(21)의 '황색신호 점등 유지 시간'을 의미한다.Here, 't 1 ' is the 'remaining time until the yellow signal is turned on' of the vehicle traffic light 21 calculated in step S210, 't 2 ' is the 'yellow signal lighting holding time of the vehicle traffic light 21 calculated in step S220 'Means.
안전계수(s)는 도로의 특성(내리막 도로, 오르막 도로, 직선 도로, 곡선 도로)을 고려하여 대략 1-2초로 설정됨이 일반적이다. 안전계수(s)를 작게 설정할 수록 보다 안전하다.Safety factor (s) is generally set to about 1-2 seconds in consideration of the characteristics of the road (downhill road, uphill road, straight road, curved road). The smaller the safety factor (s) is, the safer it is.
한편, 안전계수(s)는 도로의 특성 외에도 날씨(맑음, 흐림, 강우, 강설), 현재시간(일출전, 낮, 일몰후, 밤) 등을 더 고려하여 설정할 수 있는데, 이 경우 안전계수(s)는 상황에 따라 실시간으로 자동 변경될 수 있다.On the other hand, the safety factor (s) may be set in consideration of the weather (sunny, cloudy, rainfall, snowfall), the current time (daylight, daytime, after sunset, night), in addition to the characteristics of the road, in this case, the safety factor ( s) can be changed automatically in real time according to the situation.
"|t4-(t1+t2)| ≤ s"인 경우는, 횡단보도를 향해 주행하는 차량이 정차하는데까지 소요되는 시간이 매우 크지 않은 경우로, 보행자가 보행신호를 위반하여 사전출발하거나 지정된 횡단보도를 벗어난 무단횡단시 교통사고의 위험에 직면하는 경우에 해당한다.In case of "| t 4- (t 1 + t 2 ) | ≤ s", it is a case that the time required for the vehicle traveling toward the crosswalk to stop is not very large. Or face the risk of a traffic accident in an unauthorized crossing outside the designated crosswalk.
이에 따라, "|t4-(t1+t2)| ≤ s"인 경우에는, 안전 유도부(150)를 통해 보행자에게 '사전출발'이나 '횡단보도를 벗어난 무단횡단'의 위험을 경고한다.Accordingly, in the case of "| t 4- (t 1 + t 2 ) | ≤ s", the safety guiding unit 150 warns the pedestrians of 'pre-start' or 'unauthorized crossing beyond the crosswalk'. .
S300단계에서 안전 유도부(150)를 통한 위험 경고는, 음향 출력부(152)에 의한 음향 경고, 전광판(153)에 의한 문자 경고, 경광등(154)을 통한 시각적 경고 등을 통해 가능하다.Danger warning through the safety induction unit 150 in step S300, it is possible through a sound warning by the sound output unit 152, a text warning by the electric sign 153, a visual warning through the warning light 154.
한편, S280단계에서 산출된 '차량의 제동 소요 시간(t4)'과 't1 + t2'에 대한 차의 절대값(|t4-(t1+t2)|)이 안전계수(s)를 초과하면(S310-Y), 제어부(140)는 보행자 신호등(22)의 적색신호 점등이 연장되도록, 교통신호 처리부(110)를 제어한다(S320). S320단계에서, 보행자 신호등(22)의 적색신호 점등 연장은, 보행자 신호등(22)의 녹색신호 점등 지연을 의미한다.Meanwhile, the absolute value of the vehicle (| t 4- (t 1 + t 2 ) |) for the vehicle braking time (t 4 ) and 't 1 + t 2 ' calculated in step S280 is a safety factor ( When exceeding s (S310-Y), the control unit 140 controls the traffic signal processing unit 110 so that the red signal lighting of the pedestrian traffic light 22 is extended (S320). In step S320, the red signal lighting extension of the pedestrian traffic light 22 signifies a delay of the green signal lighting of the pedestrian traffic light 22.
"|t4-(t1+t2)| > s"인 경우는, 횡단보도를 향해 주행하는 차량이 정차하는데까지 소요되는 시간이 매우 큰 경우로, 보행자가 보행신호를 준수하여 횡단보도 내에서 횡단한다 하더라도 교통사고의 위험에 직면하는 경우에 해당한다.In case of "| t 4- (t 1 + t 2 ) |>s", the time required for the vehicle traveling toward the crosswalk to stop is very large. Even if you cross from, you face the risk of a traffic accident.
이에 따라, "|t4-(t1+t2)| > s"인 경우에는, 보행자 신호등(22)의 적색신호 점등을 연장시켜, 보행자가 횡단보도에 진입하는 시점을 늦춘다.Accordingly, in the case of "| t 4- (t 1 + t 2 ) |>s", the red signal lighting of the pedestrian traffic light 22 is extended to delay the time at which the pedestrian enters the crosswalk.
한편, S320단계에 의해 보행자 신호등(22)의 적색신호 점등이 연장되어 녹색신호가 지연 점등되더라도, 녹색신호의 소등 시점은 변함이 없다. S320단계에 의한 적색신호 점등 연장에 의해 길어진 적색신호의 점등 시간 만큼 녹색신호 점등 시간이 줄어들게 될 뿐이므로, S320단계에 의해 이후의 교통신호 체계가 흐트러지지 않는다.On the other hand, even if the red signal of the pedestrian traffic light 22 is turned on by the step S320 and the green signal is delayed lit, the time of turning off the green signal does not change. Since the green signal lighting time is reduced only by the lighting time of the red signal lengthened by the red signal lighting extended by the step S320, the subsequent traffic signal system is not disturbed by the step S320.
S320단계에 의한 점등 연장 시간은, 제어부(140)에 의해 결정된다. 적색 신호 점등 연장 시간을 결정함에 있어, 제어부(140)는 S280단계에서 산출된 '차량의 제동 소요 시간(t4)'을 참조할 수 있다.The lighting extension time by the step S320 is determined by the controller 140. In determining the red signal lighting extension time, the controller 140 may refer to the vehicle braking time t 4 calculated in operation S280.
구체적으로, 적색신호 점등 연장 시간은 '차량의 제동 소요 시간(t4)'에 비례하도록 할 수 있다. 즉, '차량의 제동 소요 시간(t4)'이 클수록(차량이 정차하는데 소요되는 시간이 길수록) 적색신호 점등 연장 시간은 많이 길어지고, '차량의 제동 소요 시간(t4)'이 작을수록(차량이 정차하는데 소요되는 시간이 작을수록) 적색신호 점등 연장 시간은 적게 길어지도록 구현가능하다.In detail, the red signal lighting extension time may be proportional to the vehicle braking time t 4 . That is, the larger the braking duration (t 4 ) of the vehicle (the longer the vehicle takes to stop), the longer the red signal lighting extension time is, and the smaller the braking duration (t 4 ) of the vehicle is. (The less time the vehicle takes to stop), the longer the red signal lighting extension time can be implemented.

Warning of danger to pedestrians through the sound output unit 152, it is possible to induce a safe driving to the driver through the electric sign 153 or the warning light 154.
한편, 제어부(140)는 횡단보도 교통 평온화 시스템의 구성 요소들에 대한 정상작동 유무를 상시 감시하고, 이상 발생이 발생한 것으로 판단되면 지역 중계기를 통하여 관제센터의 모니터링 시스템으로 상황을 통보하여, 신속한 현장 조치가 가능하도록 조치할 수 있다.On the other hand, the control unit 140 constantly monitors the normal operation of the components of the pedestrian crossing traffic calming system, and if it is determined that an abnormality has occurred, notify the situation to the monitoring system of the control center through the local repeater, promptly, Action may be taken to enable field action.
또한, 조명부(1151)는 다수의 광원 소자들을 구비하도록 구현하는데, 개별 광원소자 중 하나 또는 그 이상의 돌발적인 고장이 발생하더라도 전체 광출력의 감소율이 20%를 초과하지 않도록 구성함이 바람직하면, 만약 감소율이 20%를 초과하는 경우, 제어부(140)를 통해 관제센터의 모니터링 시스템으로 상황을 통보하여, 신속한 현장 조치가 가능하도록 조치할 수 있다.In addition, the lighting unit 1151 is implemented to include a plurality of light source elements, if it is preferable to configure such that the reduction rate of the total light output does not exceed 20% even if one or more accidental failures of the individual light source elements occurs, If the reduction rate exceeds 20%, the control unit 140 may be notified of the situation to the monitoring system of the control center, so that prompt on-site action may be possible.
