Description

횡단보도 보행자의 안전 관리 시스템Crosswalk Pedestrian Safety Management System
본 발명의 횡단보도 영역을 횡단하는 보행자의 안전한 보행을 유도하고, 횡단보도 영역으로 진입하는 차량 운전자에게 횡단보도의 보행자 보행 상황을 진입 전 미리 인지될 수 있도록 하여 횡단보도에서 보행자의 안전사고를 예방할 수 있도록 한 횡단보도 보행자의 안전 관리 시스템에 과한 것이다.Inducing safe walking of pedestrians crossing the crosswalk area of the present invention, and allowing the driver of a vehicle entering the crosswalk area to be aware of the pedestrian walking situation of the crosswalk before entering the crosswalk to prevent safety accidents of pedestrians It is an overstatement to the pedestrian safety management system that allowed pedestrians to crosswalk.
횡단보도 지역은 보행자의 경로상 횡단을 위해 보행자가 대기하거나, 보행자가 보행자 신호의 지시에 따라 횡단하게 되는 공간 등을 의미한다.A crosswalk area refers to a space where pedestrians wait to cross on a pedestrian path or where pedestrians cross according to the instructions of pedestrian signals.
일반적으로 횡단보도의 보행자 신호는 차량신호와 연동되고, 차량신호가 적색으로 지시할 경우 보행자 신호는 녹색 현시를 점등하여 차량의 흐름을 정지로 유도한 후 보행자가 안전하게 횡단할 수 있도록 한다.In general, the pedestrian signal of the crosswalk is linked with the vehicle signal, and when the vehicle signal indicates in red, the pedestrian signal turns on the green indicator to induce the flow of the vehicle to stop and then allows the pedestrian to cross safely.
이러한 횡단보도 지역은 보행자와 차량간의 사고가 발생되어 교통약자인 보행자가 부상을 입거나 사망하게 되는 등의 인적 피해가 큰 지역으로서, 보행자와 차량은 각각의 신호를 준수해야 한다.Such a crosswalk area is an area where an accident between a pedestrian and a vehicle occurs, resulting in injury or death of a pedestrian who is weak in traffic, and the pedestrian and vehicle must obey their respective signals.
횡단보도 지역의 사고는 차량이 신호를 위반하는 경우, 보행자 신호가 적색임에도 불구하고 보행자가 신호를 무시하고 횡단하는 경우, 보행자 신호가 녹색이지만 잔여 보행자 녹색시간에 비해 보행자가 안전하게 횡단할 수 있는 시간이 짧아서 사고가 발생하는 경우 등 여러 가지 가능성이 존재한다.Accidents in the crosswalk area occur when a vehicle violates a signal, when a pedestrian ignores the signal even though the pedestrian signal is red, and crosses the pedestrian safely, the time the pedestrian can safely cross compared to the remaining pedestrian green time although the pedestrian signal is green. Since this is short, there are several possibilities, such as when an accident occurs.
보행자 신호가 적색일 경우 보행자가 횡단보도에서 대기하는 시간이 길어지거나, 보행자 신호가 녹색일 경우 보행자가 잔여 보행자 녹색시간을 무시하고 횡단을 시도하는 경우 혹은 고령자, 어린이 및 장애인과 같은 교통약자의 느린 보행속도에 따라 횡단보도 녹색시간이 충분하지 않은 경우 등에서의 교통사고는 횡단보도 시스템이 잘 구비되어 있다 하더라도 흔히 발생할 수 있는 문제점이라 할 수 있다.If the pedestrian signal is red, pedestrians wait longer at the crosswalk, if the pedestrian signal is green, pedestrians ignore the remaining green time for pedestrians and attempt to cross, or Traffic accidents, such as when the green time for crosswalks is not sufficient depending on the walking speed, is a problem that can occur frequently even if the crosswalk system is well equipped.
한편, 최근 널리 도입되고 있는 보행자의 압버튼 스위치 정보를 이용하여 보행자가 대기하고 있음을 알려주거나, 보행자 신호 시간을 연장할 수 있도록 하는 가변형 시스템 등을 통하여 보행자의 편의성과 안전성을 높이려는 시도들이 진행되고 있다.Meanwhile, attempts are being made to improve pedestrian convenience and safety through a variable system that informs pedestrians that pedestrians are waiting by using the pressure button switch information of pedestrians, which has been widely introduced recently, or extends the pedestrian signal time. is becoming
선행기술로는, 보행자가 횡단보도를 횡단하고 있거나 횡단보도에 접근하는 차량이 감지될 때에는 횡단보도로 진입하는 진입도로 측에 전광판을 이용한 영상에 의해 횡단보도의 상황을 알려져 줌과 동시에 차량신호등을 적색으로 점등시키고, 보행자가 횡단보도를 완전히 건너면 보행자신호를 적색으로 점등시키고 동시에 차량신호등을 녹색으로 전환시켜 자동차가 횡단보도를 통과하도록 하며, 횡단보도를 통과한 자동차가 진출차도를 통과할 때에 이를 감지하여 차량신호등을 노란색으로 점멸시켜 연동하도록 하는 내용이, 대한민국 공개특허 제10-2012-0095538호(교통신호등과 연계되는 횡단보도의 교통신호 방법)에 개시되었다.In the prior art, when a pedestrian is crossing a crosswalk or a vehicle approaching the crosswalk is detected, the situation of the crosswalk is notified by an image using an electric signage on the side of the approach road entering the crosswalk, and the vehicle traffic lights are displayed at the same time. When a pedestrian completely crosses the crosswalk, the pedestrian signal is turned on red, and the vehicle traffic light is turned green at the same time to allow the vehicle to pass through the crosswalk. The content of detecting and interlocking the vehicle traffic light by flashing yellow was disclosed in Korean Patent Application Laid-Open No. 10-2012-0095538 (traffic signal method of a crosswalk linked to a traffic light).
다른 선행기술로는, 전체 신호주기는 일정하게 유지되도록 하여 신호등의 연동제어 체계를 유지하면서 보행약자의 보행신호를 연장할 수 있는 내용이, 대한민국 등록특허 제0797577호(보행신호 시간 연장 가변형 시스템)에 개시되었다.As another prior art, Korean Patent Registration No. 0797577 (Variable walking signal time extension system) is a content that can extend the walking signal of the weak walking while maintaining the interlocking control system of the traffic light by maintaining the entire signal cycle constant. was initiated in

일 예로 상기 객체분석부(20)는 수신한 영상신호를 분석하여 복수의 보행자에 대한 시선을 감지하고, 시선이 설정된 기준보다 낮은 위치를 향하는 보행자를 검출하며, 검출된 보행자를 이상 행동 대상자로 판단 및 지정할 수 있다.For example, the object analysis unit 20 analyzes the received image signal to detect gazes on a plurality of pedestrians, detects a pedestrian whose gaze is lower than a set reference, and determines the detected pedestrian as a target for abnormal behavior and can be specified.

It is possible to detect one or more pedestrians entering the crosswalk area (a) while it is in progress, and to determine and designate the detected pedestrian as a target for abnormal behavior.
이는 횡단보도의 적색 신호 시 보행자가 횡단보도 영역(a)으로 진입하거나 또는 횡단보도를 횡단하는 보행자를 감지하고, 해당 보행자를 이상 행동 대상자로 지정하는 것이다. This is to detect a pedestrian entering the crosswalk area (a) or crossing the crosswalk when the red signal of the crosswalk is received, and designate the pedestrian as a target for abnormal behavior.
또 다른 예로 상기 객체분석부(20)는 횡단보도에 기설치된 신호제어기(1)와 연결되어 신호제어기(1)로부터 보행자 신호를 전달받고, 수신한 영상신호를 분석하여 복수의 보행자에 대한 횡단보도 영역(a) 진입 시점 및 보행속도를 개별 감지하고, 보행자 신호의 녹색등 신호의 잔여 시간과 보행자의 진입 시점 및 보행속도를 근거로 각 보행자의 횡단 가능 여부를 판단하여 횡단이 불가능하다고 판단되는 하나 이상의 보행자를 검출하며, 검출된 보행자를 이상 행동 대상자로 판단 및 지정할 수 있다.As another example, the object analysis unit 20 is connected to the signal controller 1 installed in the crosswalk, receives the pedestrian signal from the signal controller 1, and analyzes the received image signal to cross the crosswalk for a plurality of pedestrians.

즉 상기 신호등제어모듈(400)은 신호제어기(1)와 연동되어 기존 횡단보도용 보행자 신호등과 동일한 기능을 수행하는 것으로, 횡단보도의 설치 폭에 따른 적색신호등과 녹색신호등의 교대 주기와 지속 시간 등을 설정할 수 있으며, 잔여 시간에 따라 깜박임 표현을 위하여 각 신호등의 점멸 구동을 제어할 수 있다.That is, the traffic light control module 400 is linked with the signal controller 1 to perform the same function as the existing pedestrian traffic lights for crosswalks, and the alternating cycle and duration of red and green traffic lights according to the installation width of the crosswalk, etc. can be set, and the blinking operation of each traffic light can be controlled for blinking expression according to the remaining time.
상기 광조사모듈(410)은 상기 안전관리부(30)로부터 출력되는 제 1위험신호를 전달받고 횡단보도 영역(a)으로 상기 제 1위험신호에 대응하는 보행자 주의를 표시할 수 있다.The light irradiation module 410 may receive the first danger signal output from the safety management unit 30 and display a pedestrian caution corresponding to the first danger signal in the crosswalk area (a).
일 예로 상기 광조사모듈(410)은 상기 횡단보도를 향하는 전방 위치에 적어도 하나 이상의 레이저빔 조사기기가 마련되며, 상기 안전관리부(30)로부터 전달된 제 1위험신호에 응답하여 상기 레이저빔 조사기기를 작동시켜 횡단보도 영역(a)으로 레이저빔을 조사함으로써, 이어폰 사용 보행자에게 시각적으로 주의를 표시하게 된다.For example, the light irradiation module 410 is provided with at least one laser beam irradiation device at a front position facing the crosswalk, and in response to the first danger signal transmitted from the safety management unit 30, the laser beam irradiation device By irradiating the laser beam into the crosswalk area (a) by operating the device, attention is visually displayed to pedestrians using earphones.
이때 상기 객체분석부(20)는 수신한 영상신호를 분석하여 이상 행동 대상자로 지정된 보행자에 대한 횡단보도 영역(a) 내에서의 이동 방향과 위치 정보를 출력하여 상기 볼라드(40)로 송신할 수 있다.At this time, the object analysis unit 20 analyzes the received image signal, outputs the movement direction and location information in the crosswalk area (a) for the pedestrian designated as the target of abnormal behavior, and transmits it to the bollard 40. have.
그리고 상기 광조사모듈(410)은 이상 행동 대상자로 지정된 보행자에 대한 이동 방향과 위치 정보 상기 객체분석부(20)로부터 수신하여 횡단보도 영역(a) 내에서 볼라드(40)와 지정된 보행자 간의 실시간 거리 정보를 산출하며, 산출된 거리 정보에 기반하여 상기 레이저빔의 조사 각도가 조정되도록 제어함으로써 보행자의 이동을 따라 조사되도록 하여 보행자가 보다 용이하게 주의 표시를 식별 가능하게 할 수 있다.And the light irradiation module 410 receives the movement direction and location information for the pedestrian designated as the target of abnormal behavior from the object analysis unit 20, and the real-time distance between the bollard 40 and the designated pedestrian within the crosswalk area (a) Information is calculated, and by controlling the irradiation angle of the laser beam to be adjusted based on the calculated distance information, it is irradiated along the movement of the pedestrian so that the pedestrian can more easily identify the attention mark.
상기 광조사모듈(410)에 의한 레이저빔의 조사 높이와 각도는 신장이 작은 어린이의 눈높이를 고려하여 그보다 상대적으로 낮은 높이로 설정하는 것이 바람직하다. The height and angle of the laser beam irradiation by the light irradiation module 410 is preferably set to a relatively lower height than that in consideration of the eye height of a small child.
상기 음향출력모듈(420)은 상기 광조사모듈(410)과 마찬가지로 상기 안전관리부(30)로부터 출력되는 제 1위험신호를 전달받고, 전달된 제 1위험신호에 응답하여 경고 음향을 출력하여 전방을 주시하지 않은 스마트폰 등의 사용 보행자에게 청각적으로 주의를 표시하게 된다.The sound output module 420 receives the first danger signal output from the safety management unit 30 like the light irradiation module 410, and outputs a warning sound in response to the transmitted first danger signal to move forward. Pedestrians using smartphones, etc. that are not looking at them are audibly alerted.
이때 상기 경고 음향은 경고를 안내하는 음성이거나, 통상의 경고 기계음 중 하나 일 수 있으며, 상기 음향출력모듈(420)은 상기 경고 음향의 불륨을 선택적으로 조정할 수 있다.At this time, the warning sound may be a voice for guiding a warning or one of a general warning mechanical sound, and the sound output module 420 may selectively adjust the volume of the warning sound.
한편 본 발명의 또 다른 실시 예로써, 상기 안전관리부(30)의 제 1위험신호를 전달받아 표출하는 보조시설물은 횡단보도 영역(a) 내부에 설치되는 구조물일 수 있다.Meanwhile, as another embodiment of the present invention, the auxiliary facility for receiving and expressing the first danger signal from the safety management unit 30 may be a structure installed inside the crosswalk area (a).
도 4를 참조하여 본 실시 예를 설명하자면, 상기 보조시설물은 상기 횡단보도 영역(a) 내에서 횡단 방향을 따라 일정 간격으로 설치되는 복수의 지면경고등(60)과, 상기 안전관리부(30)로부터 출력되는 제 1위험신호를 전달받고 전달된 제 1위험신호에 응답하여 상기 복수의 지면경고등(60)을 점멸 구동시키는 점멸제어기(50)를 더 포함할 수 있다.To explain this embodiment with reference to FIG. 4 , the auxiliary facilities include a plurality of ground warning lights 60 installed at regular intervals along the cross direction within the crosswalk area a, and the safety management unit 30 from the It may further include a blinking controller 50 for receiving the output first danger signal and blinking and driving the plurality of ground warning lights 60 in response to the transmitted first danger signal.
여기서, 본 실시 예의 객체분석부(20)에서는 수신한 영상신호를 분석하여 이상 행동 대상자로 지정된 보행자에 대한 횡단보도 영역(a) 내에서의 이동 방향과 위치 정보를 출력하여 상기 점멸제어기(50)로 송신한다.Here, the object analysis unit 20 of the present embodiment analyzes the received image signal and outputs movement direction and location information in the crosswalk area (a) for a pedestrian designated as a target for abnormal behavior to output the blinking controller (50) send to
그리고 상기 점멸제어기(50)의 경우 이상 행동 대상자로 지정된 보행자에 대한 이동 방향과 위치 정보 상기 객체분석부(20)로부터 수신하여 횡단보도 영역(a) 내에서 지정된 보행자의 실시간 위치를 추정하고, 추정된 실시간 위치에 대응하여 상기 복수의 지면경고등(60)을 선택적으로 점멸 구동시킴으로써 보행자가 보다 용이하게 주의 표시를 식별 가능하게 할 수 있다.And in the case of the blinking controller 50, the movement direction and location information for the pedestrian designated as the target of abnormal behavior is received from the object analysis unit 20 to estimate the real-time location of the designated pedestrian in the crosswalk area (a), and estimate By selectively flickering and driving the plurality of ground warning lights 60 in response to the real-time location, it is possible for a pedestrian to more easily identify a caution sign.
여기서 상기 지면경고등(60)은 횡단보도 상에 매립형으로 설치되는 LED모듈일 수 있다.Here, the ground warning light 60 may be an LED module installed in a buried type on a crosswalk.
한편 본 발명의 시스템에서는 횡단보도 영역(a)으로 진입하는 우회전 차량으로부터 보행자의 안전이 확보될 수 있도록 차량의 진입 전 보행자의 보행 여부를 차량의 운전자에게 식별되도록 하는 안전 수단을 더 포함할 수 있다.On the other hand, the system of the present invention may further include a safety means for allowing the driver of the vehicle to identify whether the pedestrian is walking before the vehicle enters so that the safety of the pedestrian can be secured from the right-turning vehicle entering the crosswalk area (a). .
도 5 및 도 6을 참조하면, 상기 안전관리부(30)는 상기 객체분석부(20)로부터 신호제어기(1)의 보행자 신호와 객체 분석 결과를 전달받고 보행자 신호의 녹색등 신호가 유지되는 동안 또는 적색등 신호 시 횡단보도 영역(a) 내에 보행자가 존재하는 경우, 다른 차도로부터 횡단보도 영역(a) 내로 진입하는 우회전 차량에게 인지되도록 하는 제 2위험신호를 출력하여 송신할 수 있다.5 and 6 , the safety management unit 30 receives the pedestrian signal and the object analysis result of the signal controller 1 from the object analysis unit 20 and while the green light signal of the pedestrian signal is maintained or When a pedestrian is present in the crosswalk area (a) at the time of the red light signal, a second danger signal to be recognized by a right-turning vehicle entering into the crosswalk area (a) from another roadway may be output and transmitted.
즉 본 실시 예에 따른 상기 안전관리부(30)는 횡단보도에서 보행자가 보행 중이라고 판단하게 되면, 우회전 차량의 진입 전 해당 차량의 운전자에게 주의를 주도록 하는 제 2위험신호를 출력하게 되는 것이다.That is, when the safety management unit 30 according to the present embodiment determines that the pedestrian is walking in the crosswalk, the second danger signal is output to give attention to the driver of the vehicle before the right-turning vehicle enters.
이와 같은 안전관리부(30)의 제 2위험신호는 앞서 설명한 횡단보도의 보조시설물을 통해 표출될 수 있는 바, 예를 들면, 상기 복수의 볼라드(40) 중 다른 차도에서 차량이 우회전으로 횡단보도 영역(a)에 진입함에 있어 가장 인접하는 하나의 볼라드(40)를 통해 상기 제 2위험신호가 시각적 또는 청각적으로 표시되게 할 수 있다.Such a second danger signal of the safety management unit 30 may be expressed through the auxiliary facilities of the crosswalk described above, for example, the vehicle turns right in the crosswalk area in another roadway among the plurality of bollards 40 . When entering (a), the second danger signal may be displayed visually or audibly through one of the most adjacent bollards 40.
구체적으로 복수의 볼라드(40) 중 다른 차도에서 차량이 우회전으로 횡단보도 영역(a)에 진입함에 있어 가장 인접하는 하나의 볼라드(40)는, 상기 안전관리부(30)에서 송신하는 제 2위험신호를 수신하고, 다른 차도로부터 차량의 우회전이 시작되는 위치부터 상기 횡단보도 영역(a)에 진입 전 위치까지의 회전영역(b)을 향하여 하나 이상의 레이저빔을 조사하는 주의표시모듈(430)을 더 포함할 수 있다.Specifically, when the vehicle enters the crosswalk area (a) with a right turn on the other roadway among the plurality of bollards 40, the most adjacent one bollard 40 is a second danger signal transmitted from the safety management unit 30 A caution display module 430 for receiving and irradiating one or more laser beams toward the rotation area (b) from the position where the right turn of the vehicle starts from the other roadway to the position before entering the crosswalk area (a) may include
이때 상기 레이저빔은 모든 회전영역(b)을 대상으로 조사될 수 있으며, 선택된 한 곳에 집중 조사될 수 있다. 바람직하게 상기 레이저빔은 다른 차도로부터 차량의 우회전이 시작되는 위치에 근접하는 위치에 조사되게 함으로써 차량의 운전자가 진입 이전부터 횡단보도를 보행하는 보행자의 존재가 사전 인지되도록 한다.In this case, the laser beam may be irradiated to all the rotational regions b, and may be irradiated to a selected one. Preferably, the laser beam is irradiated to a position close to a position where the right turn of the vehicle starts from another roadway, so that the driver of the vehicle is pre-recognized of the presence of a pedestrian walking in the crosswalk before entering.

It may further include one or more detection modules 440 for detecting a vehicle in the rotation area (b) up to the position before entering the sidewalk area (a) and outputting and transmitting a detection signal.
그리고 상기 주의표시모듈(430)은 상기 감지모듈(440)에서 송신하는 감지신호를 수신하고 감지신호가 유지되는 동안 상기 하나 이상의 레이저빔이 조사되도록 제어하여 우회전 차량이 횡단보도로 진입하지 않을 경우에는 불필요하게 상기 회전영역(b)으로 레이저빔이 조사되는 것을 방지하도록 한다.And the caution display module 430 receives the detection signal transmitted from the detection module 440 and controls the one or more laser beams to be irradiated while the detection signal is maintained. The laser beam is prevented from being unnecessarily irradiated to the rotation region (b).
이처럼 본 발명의 시스템에서는 횡단보도 영역(a)으로 진입하는 차량의 운전자에게 보행자 유무가 사전 인지되게 하여, 사고 비율이 다소 높은 우회전 차량으로 인한 보행자의 인사 사고가 최소화될 수 있도록 한다.As such, in the system of the present invention, the presence or absence of a pedestrian is recognized in advance by the driver of the vehicle entering the crosswalk area (a), so that the personnel accident of the pedestrian due to the right-turning vehicle having a rather high accident rate can be minimized.
