초록

기존 간선급행버스체계(BRT)의 신속성 및 정시성 저해 문제를 해결하기 위해 도시철도의 이점을 BRT에 적용한 고급 간선급행버스체계(S-BRT)가 등장하였다. 국내 지침에서는 S-BRT 주행로를 기존 BRT 주행로와 동일한 전용차로와 전용도로로 분류하였다. 그러나 S-BRT와 BRT는 상이한 운행 목표와 특성을 지님으로 서로 다른 체계적인 S-BRT 주행로 구분이 필요하다. 이에 본 연구는 국내 여건을 바탕으로 S-BRT 주행로를 전용차로, 혼용차로, 일반차로로 분류하였다. 이후 목표 서비스 수준 달성을 위해 각 주행로별 특성을 바탕으로 대중교통 우선 신호 제어 전략을 제시하였다. 대부분의 분석 시나리오에서 S-BRT 목표 서비스 수준을 달성했으며 전용차로, 혼용차로, 일반차로 순으로 높은 운행 속도를 보였다. 본 결과는 S-BRT 운행시 각 주행로별 특성을 고려한 대중교통 우선신호 운영이 필요함을 시사한다. 본 연구의 결과는 향후 각 지자체에서 S-BRT 도입 시 주행로 설계와 우선신호 운영을 위한 자료로 활용 가능할 것으로 기대된다.

Super - Bus Rapid Transit (S-BRT), adding the advantages of urban railroads to BRT, has emerged to solve the problem of low speed and reliability of the existing BRT. Notably, the S-BRT driveway is classified into exclusive lanes and roads, as BRT, in the domestic guidelines. However, S-BRT and BRT have different operating goals and characteristics, so it is necessary to systematize the S-BRT driveway. Therefore, this study classified an S-BRT driveway into exclusive lane, shared lane with overtaking lane, and shared lane without overtaking lane based on domestic conditions. Subsequently, a control strategy for transit signal priority in each driveway was presented by the study based on the characteristics of the driveway to achieve the S-BRT target service level. Finally, the S-BRT target service level was almost achieved, and the travel speed was high and increased in the order respectively in the exclusive lane, shared lane with overtaking lane, and shared lane without overtaking lane in the study. Hence, it is important to operate a transit signal priority considering the characteristics of each driveway when operating the S-BRT. In essence, this study is expected to be used as a reference for driveway design and transit signal priority operation when introducing S-BRT in each local government in the future.
