The substructure of Light Rail Transit is mainly built on elevated structure that is composed of pier, girder and bridge deck. The bridge deck mostly has been made by field formed reinforced concrete so far. The objectives of the study are to find a method for design and construction of the new bridge deck. I-beam is fabricated to make grid and concrete is poured on it at factory. This type can be used for maintenance of duty line by advantages such as good quality control and short construction time.

Since PSD(Platform Screen Door) is set up at many subway stations, its design related to a safety becomes gradually important. Especially the intereference check with a running railway vehicle is the most important of performance indices. This study proposes a dynamic analysis models for the railway vehicle and rail. Some design parameters are considered in the models to find a correlation to the performance.

Nowadays, Short headway is a requirement of Signaling System applied to subway and Light Rail Transit (LRT) being constructed in Korea. To satisfy this Systematic Requirement, the accuracy of train position information on the line is one of the main element to improve ATC system safety and performance. On-board ATC system performs feasibility of Train Position as comparing data from balise installed along the track with data from tachometer installed at both axles of train.

In 2004, railway safety law was established since intimidatory factors have increased for railway industry, such as high speed rail, urban transit extension, induction of new transportations. The projects for safety system establishment and guidelines are performed including the safety guidelines for station and platform. Therefore, in this study the safety rules are examined through investigation for stations

The interests of the government and civil business owner against the Light rail transit are increasing, it may be caused by the enterprise conception which does not consider a city circumstance that the construction plan is insensitively performed. This article present the forecast method of minimum transportation demand which secures a profitability. If It is in advance investigated the number of passenger using the existing traffic system of the area, it will be possible that the LRT project is planned on a realistic basis.

Sound absorbing materials are applied to the exposed surfaces of curved subway tunnel for the reduction of curving noise level. Before the treatment, acoustical engineering simulation is performed to predict the noise level reduction for different kinds and amounts of absorbing material. The principle of geometrical acoustics is utilized to Peform the simulation efficiently and accurately. The noise levels of the inside and outside of running car body are measured to find the noise level reduction. The average noise level reduction of 8 ㏈ has been attained. It has been shown that the simulated results are comparable to the measured ones.

The vibration resulting from track-train interaction is transmitted through the tunnel structure and the surrounding ground to adjacent buildings. This paper provides a review of the ground vibration propagation mechanism and the theoretical isolation effectiveness of each transit systems. Moreover, predictive vibration values estimated from various models are compared with measured results performed in Seoul Metropolitan Subways and evaluate the applicability of those models.

우리사회는 교통시설부족으로 인하여 많은 사회적 비용을 지불하고 있다. 이에 따라 꾸준한 지하철, 도로등 교통시설을 확대하고 있으나 지하철과 도로망 확대 모두 재원 문제로 많은 어려움을 겪고 있다. 따라서 지하철보다는 수송용량은 떨어지나 건설비 및 운영비를 절감 할 수 있고, 도로건설에 따른 도시에서의 용지 확보문제를 동시해결 할 수 있는 경량전철이 계속 심도있게 부각되고 있다. 본 글은 우리 철도학회 회원들에게 경량전철의 개황과 현재 운영 또는 개발되어 있는 각종 시스템을 소개함으로서 경량전철을 이해하는데 도움을 주고자하여 이글을 기고합니다.
