  • As well as to operate a high-speed rail, our country with capability to produce high-speed train has developed a number of techniques, such as for a riding comfort improvement, automatic diagnosis for major electrical or mechanical parts, on board measurement for catenary systems and noise reduction of running rolling-stocks are still under development. In this paper, we describe the current status of operation technologies not only traditional railway wireless communication systems but also Long Term Evolution systems which would be deployed as soon as possible, like as in Europe, China and the United States. In addition, we produced the domestic wireless communication networks for railway which KORAIL Corp. has been operating and the schemes and the plans of HSR field test for the fourth generation mobile communication which should be enforced by national research and development.

  • 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.

  • 열차경합의 사전검지 및 해소 시스템(Railway Conflict Detection and Resolution System, RDCRS)은 열차운행관리 시스템(Railway Traffic Management System, RTMS)의 최상위 의사결정지원 모듈이다. 본 논문에서는 한국철도에서 RCDRS의 필요성과 국외 적용현황 및 기존 연구현황을 분석한다. 또 RCDRS를 한국철도에 적용하기 위한 전반적인 방안을 한국철도 주요 노선별 열차운영 여건을 고려하여 제시한다. 또, 철도청에서 실시하는 '사령실 통합 신호설비 시설' 사업에 관한 RCDRS의 1단계 적용방안을 제시한다.
