Abstract

It has been subject to question whether a conventional traffic signal controller can support efficient operation at grade intersections in which vehicles and tram lines cross concurrently. This study proposes a list of functional requirements for a traffic signal controller to support effective operation of trams at such an intersection. The considered details includes the combinations of geometric conditions at which vehicle, bus, and tram lines are aligned, the types of exclusive tram signals, and the combinations of various signal phases, including exclusive tram phases, which are currently undefined in the nation. The results suggest that the controller should be capable of dealing with the NEMA standard overlap relays and a quadruple-ring phase representation scheme.

일반도로와 노면전차가 교차하는 신호교차로에서 준비되어야 하는 교통신호제어 운영조건을 검토하고 이를 토대로 노면전차 교통신호와 일반차량 교통신호의 효율적 통합 운영을 지원하기 위해 현재의 교통신호제어기가 추가 확보하여야 하는 기능적 및 기술적 요구사항을 진단한다. 본 연구의 검토 내용은 도로 현장에서 발생 가능한 일반차량과 노면전차의 다양한 교차상황, 노면전차 전용신호등의 등기단자 최소 구성, 교통신호현시 순서 운영상황 조합 및 이를 기반으로 한 현시표출방안을 포함한다. 분석결과 우회전 중첩현시 표출을 위한 중첩현시 등기장치 및 노면전차와 일반차량 복합 현시운영을 위한 사중고리현시표출체계 기능을 포함하는 교통신호제어기 도입이 필요함을 제안한다.
