  • 최근 전 세계적으로 문제가 되고 있는 지구온난화의 주범인 탄소 배출에 대한 규제 움직임과 더불어 미래도시철도는 저탄소 녹색교통수단으로 다시금 각광받기 시작하고 있다. 그러나 철도수단 자체의 태생적인 단점과 장기간에 걸쳐 건설되는 인프라와 막대한 투자비용은 철도 투자확대에 여전히 걸림돌로 작용하고 있어 미래도시철도 중심의 교통체계 구축을 위한 획기적인 대안이 절실한 상황이다. 이에 컴퓨터 시뮬레이션으로 배선 설계, 차량운행, 유지보수 등 건설하려는 미래도시철도 시스템을 모델링하고, 단기/중기/장기 예측 및 효율성 분석하여 막대한 투자비용을 절감할 수 있는 미래도시철도 시뮬레이션을 통한 비즈니스 모델을 제시하려고 한다. 본 논문의 구성은 서론에서는 연구 배경 및 필요성, 연구범위에 대해 살펴본 다음, 본론에서 미래도시철도 시뮬레이션, 녹색 성장 비즈니스 모델, 사례연구 결과에 대해 설명한다. 끝으로 미래도시철도 시뮬레이션을 통한 녹색 성장 비즈니스모델의 기대효과에 대해 설명한다.

  • 도시철도시스템은 차량, 전력, 신호, 선로구축물 등이 유기적으로 결합된 복합시스템으로 고장 또는 사고가 발생하면 원인규명이 어렵고 사고에 따른 영향이 매우 크기 때문에 시스템의 신뢰성과 안전성은 매우 중요하다. 본 논문에서는 철도에서 적용되고 있는 신뢰성관련 국제 규격을 분석하여 국내에서 개발하고 있는 무인운전 도시철도시스템에 이러한 규격들의 내용들을 충족하는 관리체계를 제시하고자 한다. 즉 기존에 적용하고 있는 신뢰성 관리체계인 IEC 60300, IEC 62278, MIL-STD-785B 등의 특성과 장점을 비교분석하여 도시철도시스템에 구체적으로 적용할 수 있는 신뢰성관리체계를 제시하고자 한다.

  • 도시철도 공사, 지하철 공사, 철도청 등 각각의 운영기관이 독자적으로 정보화를 추진함으로서 국가적으로 중복투자 및 예산이 낭비되고 각 시스템간 호환성이 부족하여 정보를 공유할 수 없어 비효율적인 시스템 구축이 이루어지고 있는 실정이며 표준화된 정보의 부재 및 부정확한 표준에 의한 업무의 비효율성이 가중되고 사고예방 및 신속한 복구지원을 통한 대국민 안전서비스 제공 및 열차운행의 안전성 확보에 미흡한 실정이다. 본 논문은 국내 도시철도분야를 세계적인 경쟁력을 가진 분야로 육성하고 수명주기비용(Life Cycle Cost)을 최소화 및 최적화하여 경제성을 극대화시킨 도시철도 정비유지체계 정보화 시스템의 개발 및 시범적용을 위해 정보전략계획 (ISP)을 수립하기 이전에 수행한 선행연구 결과이다.

  • With designing alignment of railway for urban rail transit, a greater attention is paid to the riding safety and the comfort of the passengers. Especially, cant, transition curve, minimum curve radius are considered as very important alignment factors for the curve. For the above alignment factors, in this study, comparative studies on the design criteria of foreign rail transit are conducted. And reasonable design criteria of the alignment for urban rail transit are proposed.

  • As the urban railroad durability period law has revised on march 19, 2009, the life cycle of urban railroad cars has lengthened to 40 years for the longest period. It seems to be attributed to the development of railroad car making technique along with their durability being longer thanks to the quality improvement of their materials and parts. As the stability of urban railroad cars is directly linked to the safety of passengers, safety should be considered first, and more precise examination is necessary for endurance extension. Hereupon, the rolling stocks with their durability near expiration should get precise diagnosis following the revised "RDG for urban railroad cars" This study aims to suggest a diagnosis method for the institute and the urban railroad operating body which enforce the revised diagnosis, through the case of Busan transportation corporation which firstly started the revised diagnosis after the durability related law has been revised.

  • Today, ever growing population density in Seoul or areas near Seoul is problematic. To overcome the problem, the government tries to construct so called, 'New-towns'near Seoul to spread out the population over larger areas. But building new-towns created another problem of traffic between Seoul and New-towns. It can be solved if more public transportation systems such as urban railroads are constructed. In order to succeed in urban railroad construction, we have to make a perfect plan through in depth research on characteristics of the urban train and the construction site. In this paper, we propose a method to design the Decision Support Systems(DSS) using Geographic Information Systems(GIS) and Spatial Analysis for the planning of urban railroad construction.

  • We may consider the inducement of demand to public transportation as a solution to relieve traffic congestion and pollution. Subway has merits as moving on schedule, transporting more people than bus. But subway is required a vast investment in the early stage of construction has a huge debt. So it runs into red figures, and on this account, services of subway are falling more and more. Development of subway's operation cost function is useful to understand structure of subway's operation and catch the relations of operation cost and actual results. In addition, we can present the policy that is a helpful to the operation as development of operation cost function. But there are short of studies about operation cost deal with a subway comparison with local train. Because local train has many lines and data, on the other hand, subway has one to four lines and less data. Most of previous studies sought the operation cost function of Seoul. So this study aimed to develop and apply the operation cost function of Seoul, Incheon, Busan and Daegu area using full allocation method. In this study, we considered the number of passengers, track-km, train-km, revenue as actual results. By appling the operation cost function, we compared the average cost of each city and confirmed the existence of economies of scale about the number of passengers, train-km.
