  • 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.

  • The main objective of this paper is to analyze university students' modal shift for commuting trip due to the introduction of new urban rail transit in a satellite city of metropolitan area. The paper uses SP(2011)/RP(2013) data collected from Yeungnam University in Gyeongsan City, which is a satellite city of Deagu Metropolitan City. So far few researches, especially using before-and-after individual SP/RP travel survey, have been conducted on analyzing university students' modal shift due to the introduction of new urban rail transit. For this research, some descriptive statistical analyses were conducted. Furthermore, some empirical logit models were estimated for analyzing factors affecting the modal shift. Finally, some important findings and policy implications are discussed. The significant findings from this research are summarized as follows. From the descriptive statistical analyses of SP and RP data, it is found that the rate of modal shift to rail transit is relatively high especially for bus travellers. Furthermore, from the empirical SP model estimation, it is found that time saving is the most important factor affecting the modal shift to urban rail transit. On the other hand, from the empirical RP model estimation, it is found that residential location is the most important factor affecting the modal shift to urban rail transit.

  • 최근들어, 도시철도 전력설비에는 온라인 상태진단이 가능한 센서를 설치하여 각 기기의 상태를 상시 감시하는 시스템이 도입되고 있다. 이러한 기술이 적용됨으로써 전력설비의 교체 주기를 판단하고, 사고를 미연에 방지 하는 등의 최적의 관리를 할 수 있게 되었다. 그러나 운영기관에 따라 다양한 방법의 진단설비가 설치되어 있어 유지보수가 어려워, 도시철도에 적합한 진단시스템의 개발이 요구되어 지고 있다. 도시철도 주요 전기설비로는 변압기, 단로기, 차단기, 정류기 등이 있다. 현재 이를 진단하기 위한 방법으로는 각 장치에 따라 부분방전시험, 유전정접시험, 절연유분석시험, 차단기동작시험 등이 있다. 본 연구에서는 현재 국내 외에서 제시되고 있는 전기설비의 온라인 상태진단 기술을 조사하고, 상용화된 온라인 상태진단 시스템을 분석하여 도시철도 전기설비에 적용 가능한 상태진단 항목과 상태진단 기법을 조사, 분석하였다.

  • This study is to retest of seoul traffic, all sorts of statistical data, the present condition of urban railway that local government and all sorts of research institution had researched. Even though, or something else with population and regional industrial distribution of seoul with worker and the present condition of the registrated cars and the change of increase, we have predicted the medium term and long-range solution. we have proposed the alternative plan about both of the problem that is the developmental construction direction of seoul urban railway and the resource insurance for urban railway construction.
