In general, a third rail current collecting shoegear is widely used in the light rail transit system since it is more efficient and economical than an overhead pantograph. Therefore, its specification is prescribed in the Korean standard specifications for the light rail transit for its applications. This paper describes the development of the third rail current collecting shoegears which is suitable to Korean situation and satisfactory to the Korean standard specifications. Two types are developed for the steel wheel and the rubber tyred AGT system, and various experiments are executed. It is found that performance of the third rail current collecting shoegear developed is proved acceptable.

최근 경량전철 건설이 정부 및 지자체의 정책과 민간자본의 투자에 힘입어 다양한 노선들이 추진되는 등 SOC 분야에 민간투자사업 형태의 참여가 증가하고 있다. 이러한 민자유치사업은 지자체를 포함한 정부뿐 아니라 민간건설업체의 입장에서도 면밀한 사업 경제성 분석을 통한 타당성 검토가 이루어져야 한다. 즉 공사비 등의 초기 투자비용 뿐 아니라 유지관리비용, 해당 시설물 운영을 통한 수익창출, 해체비용 등 생애주기측면에서의 정확한 비용 분석이 필요하다 하겠다. 그러나 불확실성 인자들의 분석과 이를 활률론적 기법에 의해 경제성을 평가할 수 있는 여건은 미흡한 실정이다. 대표적으로 경량전철 건설사업의 경우 유지관리비용에 관한 실적자료가 아직 미비하므로 정확한 비용산출 및 경제성 분석이 어려운 실정이다. 이에 본 연구에서는 최근 민자투자가 많은 경량전철사업 중 토목구조물 경제성평가를 위한 불확실성을 분석하였다. 이를 위해 먼저 경량전철 비용분류체계를 토대로 교량구조물을 대상으로 생애주기비용 측면에서 고려되어야 할 불확실성 인자를 분석하는 순으로 연구를 수행하였다. 경량전철 건설사업에 있어 시설물에 대한 유지관리 실적자료가 거의 전무한 상황임을 가정할 때, 본 연구를 통해 제시된 비용분류체계와 불확실성 인자 분석은 향후 이 분양의 LCC분석 및 경제성 평가의 자룔로 활용될 수 있으리라 기대한다.

The rubber type AGT system is operated by driverless that signaling is CBTC type. The system function is acomplished exactly to obtain the safety and reliability of system and the system is designed to minimize risk. In order to design the system, the functional analysis is performed. Recently functional analysis is performed by RDD-100 which is used and verified by aerospace, military, etc. Therefore, The design tool RDD-100 is used to perform functional analysis in AGT system development project.

LRT(Light Rail Transit System) is devided into steel-wheel train, LIM and rubber tired AGT(Automated Guide-way Transit System) The main features of LRT are low construction cost, low space, low noise, Environment-friendly, fastly, low maintenance cost. it's a civil transit transfer system of new generation became popular advanced nation. In this study, the beginning designed manufactureing rubber tired AGT turnout and guide-way system for the field application. We hope reliability for the system shall home production of turnout and guide-way

As the AGT system has never operated in Korea, the construction of test track is essential to the acquisition of safety for the passengers. However, the test track is a synthetic system including vehicle, power system, signalling, track etc, several factors must be considered. In this paper, we suggest the general guideline for the test track of AGT system and test items on test track through the investigation of leading test facilities in the world. Through continuous study and investigation, we finally will build the test track to verify the reliability requirements between the train and infrastructures

Light rail vehicle is optimized vehicle system for complex urban circumstance. LRT systems have many merits such as improve accuracy, speediness and safety. There are many LRT systems such as monorail, tram, automated guideway transit, linear induction motor propulsion and so on. These systems have operated in Japan and other advanced countries. In Korea, local government has many projects to apply the advanced LRT system. But there are no standardized specification, performance test specification, construction specification for monorail system, linear induction motor propulsion system, tram in Korea up to now. So, we need to establish of standardized to economical construction and safety. The linear induction motor system has been usually applied in Japan subway and ART(Advanced Rapid Transit) of Canada. In Korea, the linear induction motor system has been adopted for Yongin LRT and currently under construction. This paper covers the contents and technical base for main items of rolling stock, performance standard, carbody structure, bogie, electronic unit and brake equipment in order to implement linear induction motor LRT system according to local conditions.

There are many LRT systems such as monorail, tram, automated guideway transit, linear induction motor propulsion and so on. These systems have been operated in Japan and other advanced countries. In Korea, local government has many projects to apply the advanced LRT system. But there are no standards regulation, performance test regulation and construction regulation for monorail system, linear induction motor system and tram in Korea. We expect that standardization brings economical construction and safety. The linear induction motor system has been usually applied to subway in Japan and ART(Advanced Rapid Transit) in Canada. In Korea, the linear induction motor system has been adopted for Yong-In LRT and currently under construction. This paper presents signalling system and TCMS(train control and monitoring system) of linear induction motor system.
