  • 이 연구는 도시철도 교통량 배정 알고리즘의 적합성 평가를 목적으로 수행되었다. 이 알고리즘의 정확도는 교통수요 예측뿐만 아니라 네트워크의 취약성 분석이나 철도 운영기관간 운임수입 정산 등의 응용분야에서도 중요한 요소이다. 그럼에도 불구하고 알고리즘의 적합성이나 발전방향에 대한 논의는 부족하였다. 이에 본 연구는 대표적 교통량 배정 알고리즘인 최적전략 알고리즘, 경로선택 알고리즘, Dial 알고리즘을 대상으로 수도권 도시철도 이용자의 통행행태 연구에 적합한 알고리즘의 특성에 대하여 논의하였다. 이를 위해 각 알고리즘의 이론적 가정을 검토하고, 수도권 도시철도 네트워크에 적용해 그 성능을 살펴보았다. 그 결과 Dial 알고리즘이 이론적 가정의 합리성과 분석단위에 따른 계산적 효율성 측면에서 도시철도 이용자의 통행행태 분석에 우수한 것으로 나타났다.

  • 도시철도 주요구간에서는 상습적인 지연 및 후행열차로의 지연파급확산으로 구간운행시분 증대 및 정시운행 불가, 나아가 혼잡증대로 인해 이용승객이 불편이 가중되고 있다. 운행계획은 승객과의 약속이자 타 자원운영계획과 연계하여 신뢰성이 확보되어야 한다. 고밀도 운행 도시철도의 경우 정차시분이 운행시격에 미치는 영향이 가장 크며, 효율적 서비스계획 수립 시 정차시분의 관리는 매우 중요하다. 본 논문에서는 도시철도 분야의 정차시분 관련 선행연구동향을 살펴보고, 국내 운영기관 환경에서 실용적으로 활용할 수 있는 최소소요 정차시분 추정모델과 실제 현장데이터를 활용하여 수치사례를 함께 제시한다.

  • Management of indoor air quality of underground subway station is an important issue since the limited natural ventilation, limited sunshine incoming, and highly moistured atmosphere. The improvement in IAQ of platform is expected because most stations were installed with platform screen door currently, however, the poor air quality in tunnel might be affecting subway cabin indoor. In this study, we developed the air quality assessment model based on computational fluid dynamics. The geometry of air ventilation unit, seat, LCD monitors, and passengers were modeled using commercial software (Design Modeler) and fluid pattern and pollutants trajectories were analyzed by using CFX. We predicted the thermal comfort by predicted mean vote (PMV), distribution of CO2 and PM10 concentration. It is expected that this model can be used for the performance test of air cleaners which are under development.

  • While the environment of usage of information and technology is getting stable and technology is being developed more deeply due to the globalization, making information, standardization, in order to make a fast response to the new industry strategy and business environment, mutual communication and management of correct and fast information are focused on as fundamental elements of keeping competitive power. Accordingly strategic development of urban transit operation organization, storage of information technology of urban railroad, and buildup of standard information infra are very important, so that computerized information system has been built up standardizing efficient maintenance framework of urban transit facilities. To maintain these facilities efficiently, storing the real-time information by standardizing the maintenance organization and building up computerized information system are very important with management of information history of existing maintenance work. Therefore, for the efficient maintenance of track system among urban transit facilities, standardized facilities classification and definition of management elements, and the plan of designing and building standardized database about track. system through standardizing technology resources are described in this paper.

  • Underground Subway station's air pollutants are introduced from the indoor or outdoor. And Radon is a major pollutant in the subway station. Radioactive substances Radon is occuring naturally in granite tunnel wall and underground water. Especially inert gas Radon that causes lung cancer in human is anywhere but 5678 S.M.R.T. tunnels deep and pass through the granite plaque have a lot of Radon. The Radon concentration is determined by the following reasons : radon content of soil and concrete, underground water, ventilation, pressure difference, building structure, temperature, etc. So Radon concentration is hard to predict. And we can't only ventilate owing to era of high oil prices. This study focuses on our efforts for the reduction of Radon concentration. And the purpose is to provide basically datas of specially managed 15 subway station's Radon concentration.
