In this study, the tram signal priority strategies was developed and the effectiveness evaluation was performed using the tram test-track. As active tram signal priority algorithms, Early Green and Green Extension techniques were developed. We built a tram test-track of 1.5 kilometer-long and four virtual signal intersections. The case study showed that the tram delay has been improved by an average of 76% and the person delay considering the number of occupants of trams and general vehicles has been reduced by an average of 23%.

본 연구에서는 트램 우선신호의 평가를 위한 시뮬레이션 평가시스템 HILS(Hardware-Inthe-Loop-Simulation)를 개발하였다. 능동식 트램 우선신호 알고리즘으로 Early Green, Green Extension 기법을 교통신호제어기에 탑재하였으며, 실제 교통신호제어기를 미시적 교통시뮬레이터 VISSIM과 연계하여 트램의 실제 신호제어 환경을 기반으로 우선신호의 시뮬레이션 평가를 수행할 수 있도록 하였다. 사례분석을 위해 수원시의 트램 도입예정지역 4개 교차로를 대상으로 HILS 시스템을 적용하였으며, 트램 배차간격을 3분, 5분, 10분으로 차등 적용하여 트램의 지체는 우선신호 미적용시 37 대/초, 우선신호 적용시 24 대/초로 35% 이상 감소함을 확인하였다. In this study, the simulation evaluation system HILS(Hardware-In-the-Loop- Simulation) for tram signal priority evaluation system was developed. Early Green and Green Extension techniques as active tram signal priority algorithm are implemented in the signal controller. We developed a simulation evaluation system of tram signal priority algorithm by linking traffic signal controller and microscopic simulator VISSIM. The case analysis showed that the tram delay could be improved by more than 35%.

본 연구에서는 트램의 도시부 신호교차로 연동운영을 위해 도로교통 및 트램의 통합 신호시간 최적화 전략으로 통합연동모형을 개발하였다. 트램은 도로교통의 자동차 대비 가감속 능력의 제약으로 인해 신호교차로에서 불필요한 정차를 최소화하는 신호운영전략이 요구되며, 이때 통합연동모형을 사용하여 트램은 정류장에서만 정차하는 신호교차로 연동계획을 작성할 수 있다. 또한 통합연동모형에서는 도로교통의 연동폭을 최대화하는 전략을 동시에 적용하여 승용차와 트램이 함께 연동되는 신호시간 최적화가 가능하다. This research proposes a new tram progression model, Integrated Progression Model, which is a tram signal priority strategy on median tram lane. Integrated progression model was formulated for tram progression model which is capable of identifying the maximized auto bandwidth in the context of a fixed tram bandwidth. A tram that leaves a station during a green band can arrive at next station without unnecessary intersection delays and stops using the tram own green band. In order to guarantee a desired green time for other road users and minor streets, this integrated progression model determines the traffic signal timings for tram signal priority using only an offset.

In this study, the transit waiting time at signalized intersection for the active transit signal priority was modeled depending on the detector location, and this model can determine the detector location for the minimum transit delay in median exclusive tram or bus lane. With the application of the various transit speed and detector location, this study analyzed the change of transit delay. In addition, this study analyzed the active transit signal priority using a microscopic simulation under the same conditions with the analysis of transit waiting time. The result of microscopic simulation using VISSIM also showed the similar trend with the results from the waiting time model. This research made sure that the transit delay can be changed according to the detector location only, even if the delay of passenger car had a slight change.

본 연구에서는 트램과 일반차량의 통합신호운영을 위한 트램 우선신호 알고리즘의 개발과 시험선을 이용한 효과평가를 수행하였다. 도시부 간선도로에 중앙트램 전용궤도가 설치되는 상황을 고려하여 트램 우선신호로 조기 녹색시간(Early Green), 녹색시간 연장(Green Extension) 알고리즘을 수립하였다. 이와 함께 1.5km 규모의 트램 시험선에 4개 신호교차로를 구축하여 트램 우선신호의 운영 효과를 평가하였다. 트램 우선신호 운영에 따라 트램 지체는 미운영시 대비해 평균 76% 까지 개선된 결과를 나타내었으며, 일반차량 지체는 평균 9% 증가한 결과를 나타내었다. 하지만, 트램과 일반차량의 재차인원을 고려한 사람당 지체는 23% 감소하였으며, 우선신호 운영으로 트램과 일반차량의 개별 탑승자 관점에서의 지체는 개선될 수 있음을 확인하였다. In this study, a tram signal priority algorithm for the integrated operation of trams and general vehicles was developed, and the effectiveness of this algorithm was determined using a tram testrail. Active tram signal priority algorithms for the median tram rail of the urban arterial, early green, and green extension techniques were developed. We built a tram testrail with a length of 1.5 km and four virtual signal intersections. The case study showed that tram delay was improved by an average of 76%, and person delay, considering the number of tram and general vehicle occupants, was reduced by an average of 23%.
