Provided is a method to operate a tram traffic light, installed at a tramp crossroad including a tram-only lane and a general lane to detect a signal conflict, which causes a collision between a vehicle and a tram, from traffic light information of the crossroad, so as to ensure safety when the conflict occurs. According to the present invention, a tram signal device generates tram traffic light output information by each access road of a corresponding crossroad in accordance with approach information of a tram and a priority signal result of the tram to transmit the same to a traffic light controller. As traffic light feedback information by each access line is received from the traffic light controller, the signal conflict is determined when output of the tram traffic light is a tram passing signal and a vehicle traffic light of an upper lane is activated. According to the present invention, provided is an effect of preventing a collision accident caused by a traffic light conflict between a tram and a general vehicle at a tram crossroad, where the tram and the general vehicle are operated at the same time.

    트램 전용차로와 일반 차로가 포함된 트램 교차로에 설치되어 교차로의 교통신호등 정보로부터 차량과 트램과의 충돌을 야기할 수 있는 신호모순을 검지하고, 모순 발생시에 안전을 담보할 수 있도록 트램 신호등을 구동하는 방법이 제공된다. 트램신호장치는 트램의 접근정보와 우선신호 결과에 따라서 해당 교차로의 접근로별 트램신호등 출력정보를 생성하여 교통신호제어기로 전송한다. 접근로별 신호등 궤환정보를 교통신호제어기로부터 수신하여, 트램 신호등의 출력이 트램통과신호이고 상충 진로의 차량 신호등이 활성화되어 있는 경우에 신호모순이라고 판정한다. 본 발명에 따르면, 트램과 일반 차량이 혼용되어 운용되는 트램 교차로에서 신호등 모순에 의한 트램과 일반 차량의 충돌 사고를 방지할 수 있다.
