박수중(Soo Choong Park),김석호(Suk Ho Kim),김수진(Su Jin Kim) 한국철도학회 2016 한국철도학회 학술발표대회논문집 Vol.2016 No.10

최근 트램(Tram)은 경량전철보다 건설비용이 저렴하다는 이유로 여러 도시에서 도입을 검토 중에 있다. 하지만 트램의 도입자체에 집착한 나머지 “도시교통 전체에 미칠 영향과 어떤 목적에서 어떻게 운영할 것인가”에 대한 검토는 상대적으로 부족한 것이 사실이다. 본 논문에서는 도시 특성을 고려한 도시 전체적인 시각에서 트램이 가지고 있는 특성에 맞게 “어떠한 목적으로 활용될 것인가와 어떤 기능을 수행할 것인가”에 대한 운영 관점에서 트램 도입방안을 논하였다. 이를 위하여 해외 트램 운영사례를 기초하여 국내 지자체별 추진동향 분석 및 운영을 위한 법적, 제도적 검토를 하였다. Recently, a number of cities have been considering adopting trams because the construction cost of trams is cheaper than that of LRT lines. However, the effects that trams may cause in the entire city transport system of each city as well as the objectives and the way of tram operation are not relatively fully examined. This paper discusses tram adoption plans from an operator’s perspective, considering each city’s own characteristics, and focuses on how a tram’s unique characteristics can be applied to meeting the objectives of tram operation and the roles that trams may play in the entire city transport system. To clarify the discussion, examples of overseas tram operation and Korean cities’ current tram adoption plans along with tram-related legislation and systems are analyzed respectively.
