LRT (Light Rail Transit) is one of the transport modes to reduce heavy traffic in big cities and intercity. LRT line is considered to be easily linked with other transport system. The importance of new LRT lines has recently emerged as the problems solution in Korea. Thus, in this study, the turnout for AGT (Automated Guideway Transit) by computer system has been developed. And Guideway for AGT has also been developed for installation on the LRT line as well. In future, if the results of the feasibility study show the new LRT line project is viable, Kangwon Railtech shall propose design for LRT turnout, development, standardized design for guideway, and construction scheme

Recently, right rail transit (L.R.T.) systems become influential as a new traffic system in urban area to solve heavy traffic problems. However, there are little research results about the dynamic interaction problems between the vehicle and structural system, even though some studies far those static problems have been carried out. Therefore, first of ail, the dynamic equations of an interaction between vehicle system and surface roughness of the vehicle path are derived before developing the dynamic equations of vehicle-structure-surface roughness system, in this study. As a vehicle model, an automated guide-way transit (A.G.T.) system is adopted. Parametric study shows that the dynamic wheel loads of the vehicle system has a tendency to increase with vehicle speeds and stiffness of suspension system. However, those dynamic wheel loads have tendencies to decrease in according to loads of the vehicle system.

최근 일부 도시에서는 도시철도 건설 시 부정확한 수요예측에 따른 재정적 부담으로 많은 갈등을 겪은 바 있는데, 건설비용뿐만 아니라 운영비용을 잘못 예측할 경우에도 지자체 또는 정부에 막대한 예산 낭비를 초래할 우려가 있다. 특히 운영비용은 공공재인 도시철도의 요금정책에도 직접적인 영향을 줄 수 있으므로 도시철도의 현실적인 운영비용을 추정하는 모형 개발이 시급하다. 이에 본 연구에서는 도시철도의 특성을 가장 잘 설명하는 변수와 기존 연구에서 사용된 변수들보다 정확성과 신뢰성을 높일 수 있는 변수를 투입하여 운영비용의 추정모형을 개발하는 것을 목적으로 한다. 먼저 국내 도시철도를 대상으로 최근 5년의 도시철도 운영데이터를 수집하여 운영비용에 영향을 미치는 변수들을 종합적으로 검토하였고 평균 역간거리, 열차 운행 거리, 열차정원, 운전유형(유 무인), 사업유형(재정 민자)을 독립변수로 선정, 더미회귀모형을 구축하여 실질적인 운영비용을 추정하였다.

Light Rail Vehicle(LRT) is "New Transit System" that has transportation capacity as well as physical size of vehicle is in-between bus and subway. The demand of LRT system is increasing rapidly; both domestically and internationally. Reason being is that it is more economical and eco-friendly compare to existing heavy rail vehicle. Especially, Busan Subway Line 4 K-AGT (Rubber-tired LRT) being the first of its kind to start revenue service in Korea, it is very much likely that application of its demand will continue to increase. Considering its trend, study to reduce implementation cost of LRT is being pursued in many different aspects; reducing construction cost is one that aspect. In this study, on-site application of 'Up-Down Turnout System' implementation research has been carried out which can replace existing 'Left-Right Turnout System'. When safety of its type gets verified, application of this system to line which intends to use K-AGT, Shin-Lim Line and Dong-Book Line, expects to save its construction cost. This thesis paper reports ongoing research of AGT 'Up-Down Turnout System' development and main component design factors, fundamental principle, performance test result.

China's rapidly growing cities offer a unique opportunity to create highly sustainable communities. Architects and their clients, typically real estate developers, are highly focused on strategies that are effective at reducing energy and water usage at the scale of the individual building or within a master plan of multiple related buildings. However, a closer look at energy consumption reveals that transportation uses more energy worldwide than residential and commercial buildings combined. In light of this, it is appropriate that China is making massive investments in transportation infrastructure like heavy rail rapid transit and grade separated expressways, but the end result of these investments to date has been to enable people to live further from where they work and shop rather than closer - while simultaneously not creating walkable communities. Using positive and negative examples from Asia and the rest of the world, this article will investigate the specific urban design policies such as height limits, setbacks, land use restrictions, parking ratios, and parcel size which might change to enable the creation of truly sustainable communities for China's 21st century.
