Light Rail Transit (LRT) is optimized vehicle system for complex urban circumstance. LRT systems have many merits such as improved accuracy and safety. 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.

근래 지하철과 버스의 운영상 문제점이 대두되면서 신교통수단 도입이 요구되고 있다. 특히 여러 지자체들이 도입하고 있는 AGT방식의 경전철은 고가건설에 따른 도시미관 저해, 민원발생 등으로 건설이 지연되는 사례가 많아, 그에 대한 해결책으로 친환경적이고 접근이 편리한 노면전차가 대두되고 있다. 본 연구는 창원시를 친환경적인 대중교통지향형 도시로 탈바꿈 할 수 있도록 노면전차의 개요, 특징, 장 단점 등을 분석하고 이러한 시스템의 도입을 위해 기존의 대중교통수단간의 환승체계를 구축하기 위한 목적이다. 창원시 노면전차는 1단계 2018년, 2단계 2021년 개통을 목표로 추진 중에 있으며, 총 길이 33.9km 정거장 38개소를 건설할 계획이다. 2011년 예비타당성 조사에서는 B/C는 0.88로 경제성은 다소 떨어지나, 정책적 분석측면에서 AHP값이 0.502로 타당성이 있는 것으로 평가되었다. 다만 노면전차 도입 전에 선행되어야 할 과제로 첫 번째 노면전차의 도입시 버스를 포함한 대중교통 체계의 개편뿐만 아니라 자동차의 수요관리와 함께 이루어져야 하며, 국내 현실에 맞는 세심한 시스템 선정이 요구된다. 두 번째 철저한 시민공감대 형성 및 선진 시민의식이 제고되어야 하며, 노면전차의 도입에 필요한 법적인 제도가 확립되어져야 한다.

Urban railway signaling system is for train operation with safety in the urban crowded area, that has been increasing the demand of use of advanced train control systems with safe. European Commission is supporting the UGTMS(Urban Guided Transport Management System) project for the research and development. The main objective of UGTMS is to provide the European urban guided transport sector (comprising metro, tram and light rail systems) with a common Management System. A key topic is the extent to which the specifications for the successful ERTMS(European Rail Transport Management System) can be adapted to UGTMS needs. Beyond this, it is necessary to define the relevant functional and system requirements for all types of urban guided transport management systems in order to improve interoperability and intermodality. Also to be explored are the prospects for open system standards. In this article, we look into the trend of the standardization through the UGTMS project in Europe and consider any benefit to the project of the standardization for the urban railway signaling system in Korea.

A set of design factors that should be considered during rail transit system development in proposed. As the current trend in the rail transit development emphasizes its role as a medium through which the interaction between the city environment and people takes place, the factors of harmony, color, characteristics, identity, and communication should be considered in the railway-transit system design. It's important to ensure that there exist harmony between the design and the civic environment, the influence of color on people is properly considered, the car design possesses distinct characteristics, and that the sense of common identity as well as effective communication is fostered between the system and people it serves. Several cases from various countries are presented to illustrate the points raised in the paper.

Platform Screen Door, PSD, is a device that seeks to prevent accidents with regards to falling off the platform and getting trapped between the trains, achieve improvements on the cleanliness of the air, address the accessibility issue of the disabled and the elderly and provide fresher environment on the platform in general. This is achieved by preventing health hazards and accidents from occurring through installation of fixed and moving doors between rail, tram and subway platforms and the railway. Domestic firms have achieved domestic production to a large degree in various Control Units including the Overall Control Unit and RF devices through investments in technology. Despite this, full domestic production of the core of the PSD system, Door Control Unit, DCU, is not yet achieved, having to install PSDs in a relatively short period of time. Currently, controllers with DC motors are developed for installation or one is faced with having to import foreign produced controllers. In this research, the control unit prototype using the BLDC motor was domestically produced. The performance of the control unit was rigorously tested through installation on Eun-Ha Rail on Wol-Mi Island.

A number of variables and environment are concerned for the basic design of train. The design of train ran be optimized by the ruining simulation. And using the simulation result the consuming energy, regenerating power, adhesion coefficient, train traction control capacity are respectable. Considering these variables and for more information operating time, operating period, standard velocity and limit speed, the all factors of train are optimized. The light-tail tram is mainly divided into linear motor train, road surface train, iron wheel train and rubber tire train, and the most profitable one for adhesion coefficient is rubber tire train and the train will be designed.

Since adding design elements to train manufacturing technologies creates addition of high value, it is necessary to develop design for FRT with increased convenience of transportation by rail, which is a new paradigm. Therefore, an evaluation model for increasing convenience of the interior of FRT should draw the requirements of such design and their importance and supply logical basis for setting standards of establishing convenience of system and evaluating and measuring them. In order to evaluate design elements such as interior layout and arrangement of facilities, the model, of which commonness and subjectivity have been verified, should be presented. In consequence, this study going to more concretely focus on new values and sensitive technologies, application of availability and visual communication.

트램은 타 경전철과는 달리 도로에서 자동차와 혼용운행이 가능하다는 큰 특징을 가지고 있으며, 베를린, 뮌헨, 파리, 리스본 등 국외에서는 노선 버스와 일부 노선 및 정거장을 공유하는 사례도 존재한다. 현재 투자평가제도 상에서는 교통수요예측 및 편익산정 시 트램을 경전철 중 하나의 수단으로 구분하고, 도시철도의 분석방법론을 준용하고 있으나, 노선버스 특성과 유사한 트램사업 중 비수도권 사업의 경우 KTDB 배포자료에 노선버스의 O/D 및 Transit Line을 제공하지 않아 사업노선 주변 노선버스에서의 수단전환 등의 통행행태를 반영할 수 없는 구조적인 문제점이 존재한다. 본 연구는 현재 비수도권 사업에서 고려되지 않고 있는 노선버스가 트램사업에 미치는 영향을 검토하기 위하여, 현황 검토 및 문제점을 도출한 후, 노선버스 반영 여부에 따른 트램사업의 효과를 분석하여, 수요예측 및 편익산정 개선방안을 제시하였다. 본 연구를 통해 향후 투자평가체계 개선을 통한 트램사업 도입여건에 변화를 줄 수 있을 것으로 기대한다.

This study focuses on the effects of using open stator slots in an interior permanent magnet traction motor with a magnetic slot wedge design in order to increase the power density at its base speed. In addition, such a configuration reduces the torque ripple under field-weakening conditions. Five different wedge models were selected, each of which was evaluated using a finite element analysis (FEA). Based on the initial model, we designed magnetic slot wedges for maximum back-EMF and minimum cogging torque. In addition, the d-q axis inductance was slightly altered due to the magnetic slot wedges. Finally, we analyzed the performance of a traction machine under field weakening control. Moreover, we have outlined the requirements for an ideal magnetic slot wedge design.
