  • 현재 각 도시철도 운영기관이 사용하고 있는 부품코드체계는 구 정부물품 분류체계 11자리를 수요한 코드체계로의 군, 급의 2단계 분류로 구성되어 있어, 분류단계의 제약이 존재할 뿐만 아니라 분류체계의 구조적 문제로 군, 급, 품명의 빈번한 통합, 삭제에 따른 코드 관리의 어려움이 존재하고 있다. 또한, 사용자가 원하는 물품을 해당 분류체계로 찾아가기 위한 그룹별 탐색과 통계적 분석이 불가능한 실정이다. 이러한 분류체계의 문제점과 향후 차종의 노후화로 발생될 관리품목의 증가로 업무능률 저하가 예상되기 때문에 새로운 체계의 표준화된 부품코드체계가 절실히 필요한 실정이다. 본 논문은 산업 발전에 따르는 확장성과 세분화에 대한 분류구조의 탄력성을 가지고 객관적으로 분류 추가 및 변경이 가능하도록 하고, 정부 및 국제기관 표준권고안과 호환성을 가질 수 있는 표준 부품코드체계를 제정하기 위한 연구결과이다.

  • 기존 국내의 간선 철도와 도시철도에서는 궤도회로에 기반한 고정폐색방식에 의한 열차제어시스템을 사용하고 있으나, 세계적인 추세가 유지보수 비용을 줄이고 선로 용량을 증가시킬 수 있는 무선통신을 이용한 이동폐색방식에 의한 새로운 통신기반 열차 제어 시스템(CBTC(Communication Based Train Control) system)에 대한 연구가 활발히 진행되고 있으며, 특히 도시철도의 경우 이에 대한 실용화가 이루어지고 있는 실정이다. 현재 국내에서도 한국철도공사에서는 분당선 구간에 CBTC 시스템의 시범적응을 진행하고 있으며, 또한 한국철도기술연구원에서도 건설교통부가 추진하고 있는 도시철도 표준화 사업의 한 분야로 도시철도 신호시스템에 대한 향후의 표준화 방향을 CBTC 시스템으로 선정하고, 이에 대한 표준화 및 국산화 연구개발이 진행되고 있다. 또한 유럽에서 진행되고 있는 ERTMS/ETCS 시스템의 레벨 2와 3에서는 앞의 방식하고는 다른 GSM-R의 무선방식을 사용하고 있지만 이 또한 무선통신에 의한 열차제어시스템을 적용하고 있다. 본 연구에서는 이러한 무선통신을 이용한 열차제어시스템에 있어서의 안전제동모델에 대해 연구하였으며 그 결과를 소개하고자 한다.

  • Accurate demand estimating process in the construction of urban railway is very important, and precise validation is required. Existing model formula in the 4 phase model is limited in the estimation of the demand the administrative boundary-based zone system reflects no spatial railway demand characteristics around railway stations. The purpose of this study is improving the accuracy of urban rail demand estimation through segmentations of station influence areas and modal split characteristics within the areas. According to the case analysis, it is possible to set up the ststion influence area with a radius of 500m in the urban region and 1,000m in the suburban. And eastablishing proper segmentations of the ststion influence area shows more accurate results to the real demand of railway stations.

  • The recent increase of light rail construction by the private sector in Korea has caused a new issue in forecasting rail demand. Integrated fare systems between several rail operators is convenient and brings cost savings to users, and therefore is also very effective in increasing demand. However, it causes some short-term revenue loss to operators so that the private sector often suggests a non-integrated fare system. The current rail demand forecasting model is based upon an integrated fare system. Thus this model cannot be used to forecast the demand with a non-integrated fare system. Some value of transfer fare should be estimated and applied to forecast the demand in a non-integrated fare system. This study conducted a stated preference (SP) survey on urban railway passengers and estimated the value of transfer fare. The estimated value is 2,609 Won/hr, which is about 52% of in-vehicle time. This shows railway users have a tendency to pay more for transfer fares to save time or distance. This value has some limitations since it is derived from the SP survey. If some non-integrated fare system is applied in the future and a RP survey is conducted and compared with these study results, a more clear value of the transfer fare will be derived.

  • Negligent accidents in urban railway station not only give damages to users but also cause avoidance of public transport usage. This study aims to identify design factors in designing urban railway station for reducing and preventing negligent accidents in the station. Especially this study identifies design factors from the perspectives of universal design concept which is for all persons. This study classified negligent accidents in urban railway stations, analysed degree of danger and identified the causes of accidents. Then this study identified universal design factors based on the results of analysis on the priority of accident factors relating to negligent accidents. The results of this study can be utilized as basic data in designing urban railway station for reducing and preventing negligent accident in urban railway station.

  • Users of metropolitan railroad is increased continuously because of its various advantage such as comfortableness, convenience and punctuality. Thus, several local government including Seoul considered new installation or extension of railroads and four railroad operators maintain seventeen lines at present. After public transportation reforms in 2004 and integrated discount fare system in 2007, public transportation become more convenient in many aspects. However, these trials gives much more complex allocating problems of revenues among public transportation operators. In this paper, we deal with revenue allocating problems among public transportation operators after integrated discount fare system in 2007. Specifically, this study focuses on allocating revenues to metropolitan railroad operators by using RF card data. This research roughly proposes the methodology of O/D extraction from RF card data, generalized cost estimation and allocating revenue algorithm. We use RF card data in order to draw out exact individual O/D data and try to compare our results with those of Korea Smart Card Company. In generalized cost estimation, survey study about transfer factors is conducted for accurate estimation of generalized cost function. Lastly, new allocating revenue algorithm using k-path and non-dominated path concept is suggested. It is expected that case study is also performed with real revenues and O/D data in order to check up the application. Preposed methodology in this research can contribute to solve present and future revenue allocating issues according to the introduction of LRT and private railroad.
