The present invention relates to a signal control device of a variable traffic information sign using a traffic signal controller which comprises: a traffic signal control system; a traffic information collection device (40) including a camera installed at an intersection to obtain traffic information and road condition information, and a weather sensor for obtaining weather information on rainfall/snowfall/strong wind; a variable information sign operating server (50) having an algorithm for deriving an appropriate driving speed of a vehicle, determining variable display information in accordance with a traffic condition, a weather condition, and time-specific display information obtained by the traffic information collection device (40), and transmitting each display information through a communication network of a traffic signal control system operating server (20); an information linkage option module (60) for receiving a variable traffic display information signal and a safety message transmitted from a CPU (100) of a traffic signal controller (10) by being transmitted from the variable information sign operating server (50), and transmitting the same to a variable traffic information sign (70); and a variable traffic information sign (70) having a communication device for selectively controlling variable traffic signal display information in accordance with an intersection situation, receiving the variable traffic display information such as a speed limit and the safety message calculated by the variable information sign operating server (50) from a communication network of the traffic signal control system and the information linkage option module (60) to display the same in real time, and transmitting an operation status thereof to the variable information sign operating server (50) through the communication network of the traffic signal control system. Therefore, construction costs can be reduced.

    본 발명은 교통신호제어기를 이용한 가변형 교통정보 표지판의 신호제어장치로서, 교통신호제어시스템을 포함하여 교차로에 설치되어 교통정보, 노면 상태 정보를 취득하기 위한 카메라와, 강우/강설/강풍의 기상정보를 취득하는 기상검지센서를 포함하는 교통정보 수집장치(40)와; 차량의 적정운행속도를 도출하는 알고리즘을 구비하여 상기 교통정보 수집장치(40)에 의하여 취득되는 교통상황, 기후상태, 시간대별 표출정보에 따른 가변표출 정보를 결정하고, 각 표출정보들을 교통신호제어시스템 운영서버(20)의 통신망을 통해 전송하는 가변형 정보표지판 운영서버(50)와; 상기 가변형 정보표지판 운영서버(50)에서 전송되어 교통신호제어기(10)의 CPU(100)로부터 송출되는 가변 교통표출정보 신호와 안전메세지를 수신받아 가변형 교통정보 표지판(70)으로 전송하는 정보연계 옵션모듈(60)과; 교차로 상황에 따른 가변 교통신호 표출 정보의 선택 제어를 위한 통신장치를 구비하여 상기 가변형 정보표지판 운영서버(50)로부터 산출된 제한속도, 안전메시지와 같은 가변 교통표출정보를 교통신호제어시스템의 통신망 및 상기 정보연계 옵션모듈(60)로부터 전송받아 실시간으로 현시하고, 그 동작 상태를 정보연계 옵션모듈(70)과 교통신호제어시스템의 통신망을 통해 가변형 정보표지판 운영서버(50)에 전송하는 가변형 교통정보 표지판(70)을 포함하여 구성된다.
