Light-rail transit system has many characteristics of better accessibility. frequency service, low construction cost, reduced air pollution and medium-capacity public transport etc. Light rail transit system as a urban transportation system has been growing worldwide since the late 20th century. More than 300 cities around the world have light railway systems. Many medium-size cities in domestic site is planning the construction of light railway. This paper describes the development strategies for the light rail transit industry.

There has been fast progress in economy in Korea derived by a consecutive five-year plan program for economic development started in the early 1960's. In the field of transportation, rapid changes in the technological environment of transportation and communication have brought a revolution of the transport system, of which inter-modal transportation through containerisation is typical. Because of the rapidly growing traffic volumes of cargo, especially container traffic, and lack of investment into transport infrastructure in the past, both road and railway are beyond their capacity. As a result, the public-road network has suffered a serious congestion problem. For instance, in relation to the corridor between Seoul and Pusan, today, it takes about 14 hours for the journey of container trailer through Kyongbu Expressway, for which it used to take only 7 hours in 1986. For the railway, though the congestion problem is not very serious compared with the road sector, a shortage of capacity on certain main lines has emerged as a problem as railway traffic has increased. Furthermore, the further expansion of the system in near future is difficult due to burden of higher construction the cost. Unlike these two modes, coastal shipping, which has been paid relatively less attention for commodity transport in Korea, shows no constraint in this respect. In addition, it is the most cost efficient mode of transport. This work therefore aims to make a proposal for the alternative inland transportation mode, which is to promote the coastal transport of container. Three obstructing factors for the promotion of the coastal transport are investigated and some solutions for those are suggested as follows : First, it appears to be essential to provide exclusive ports for the coastal shipping, that comply with simplification, specialization and rationalization. The optimum size of berths on the exclusive ports in Pusan port is estimated as 16-20. We found that it needs periodical study and publicity on the advantages from the adoption of the coastal mode. Inducing competition in the coastal shipping market is also necessary. For the supply of the fleet in the coastal shipping, chartering of the surplus ships in the oversea shipping is found to be more desirable than new shipbuilding. Second, to solve the fragmentation of the companies which wish to participate in the coastal transport, government has to implement the subsidy policy. The encouragement of participation of the shipping lines engaging in Korea-Japan run and Korea-East South Asia run, into coastal shipping also needs to be considered cautiously. Third, simplification of the document for entry in ports is needed for rational coastal shipping management. We can use B/L (Bill of Lading) for coastal shipping as a prerequisite to get the indemnity by P & I Club. The reduction of the government controls on entering and leaving the ports also needs.

본 연구는 중앙선의 여객수송수요를 효율적으로 예측하기 위한 방법으로 계절성 요인을 고려한 ARIMA 모형을 제안하였다. 특히, 최근의 관광수요를 반영하기 위하여 2013년 4월 개통되어 운행되고 있는 중부내륙권 관광전용열차(O-train, V-train)의 수요를 포함하여 예측모형을 구축하였다. 이를 위하여 2005년 1월부터 2013년 7월까지의 월별 시계열 데이터(103개)를 사용하여 최적의 모형을 선정하였으며 예측결과 중앙선의 여객 수송수요는 지속적으로 증가할 것으로 나타났다. 구축된 모형은 중앙선의 단기수요를 예측하는데 활용이 가능하다.

The development of structural solutions for high-speed or very high-speed tracks that minimize total life cycle costs of the system is a key issue to improve the operational profitability of new investments. In opposition to conventional ballasted tracks, slab track solutions can be a cost-effective solution, but only in the cases where the benefits due to the increase in track availability and the reduction of track maintenance offsets its much higher construction costs. In the cases where such investment is not feasible, it is worth to evaluate possible structural improvements to ballasted track that allow reducing its maintenance needs without increasing too much its construction costs. This paper evaluates the design requirements and the impact of improving conventional high-speed ballasted tracks by using a bituminous subballast layer. It is divided into two main parts: first the design requirements of the structural solutions with bituminous subballast and its possible benefits on high-speed track deterioration, and secondly the evaluation of the economic impact, in terms of construction costs, of using this structural solution material in future Spanish high-speed lines.

현재 우리나라의 수도권 전철역이 499개가 있지만 철도역과 연계수단간의 연계영향권에 대한 연구가 많지 않다. 대부분 진행된 연구들은 연계영향권보다는 접근영향권에 대한 연구가 주를 이루고 있다. 또한 연계영향권의 연구들은 설문조사와 기초통계자료를 이용하여 연계영향권의 설정에 대한 이론적기반과 분석기법에 한계를 가지고 있다. 본 논문에서는 새로운 연계영향권을 설정 방법론을 정립하고 이를 빅데이터인 교통카드 이용자들의 철도역 이용 공간자료와 GIS 기반 연계영향권 분석 기법을 접목하여 수단별 네트워크 통행시간기반 연계영향권 설정 연구를 수행 하였다. 연구결과 마을버스 15분이내, 지선버스 20분이내, 간선버스 25분 이상 등의 연계영향권이 네트워크 접근시간의 차이에 따라 명확히 구분됨을 확인하였다.

우리나라 철도운영회사인 한국철도공사의 물류부문 영업계수는 2010년 190.7로서 2009년의 197.4에 비해서 소폭 개선되기는 하였으나 여전히 수익에 비해서 비용이 매우 높은 구조이다. 물류 효율화를 위한 활동들을 도출하고 그 효과를 정량적으로 파악할 수 있기 위해서는 각종 통계자료로부터 추출할 수 있는 다양한 지표의 분석이 매우 중요하다. 철도물류에 있어 가장 기본이 되는 것은 화차이며, 본 연구에서는 화차의 효율성을 판단할 수 있는 여러 가지 지표를 분석함으로써 향후 화차와 관련된 철도물류의 효율화를 위한 활동들을 평가하는 데에 활용할 수 있도록 하였다. 화차의 효율성을 파악할 수 있는 지표로서 량당 수송횟수, 량당 수송거리, 량당 수송수입을 제시하였으며, 화차의 효율성을 평가할 때 본 연구에서 제시한 각 지표의 특성 분석자료를 활용할 수 있을 것이다.

In order to promote economic cooperation and future reunification in Korean peninsula, this study is conducted to initiate a reconnecting plan for north and south Korean railways. When practical works to interconnect two counties' railway systems begin, the differences of railway systems such as rail track, railway facilities, communication systems, electrical power systems would be emerged as barrier. In this paper, to solve this problems, plan for the secure system-operational technology is presented. It also could be used for shaping the national transport network and constructing railway operating systems.

The primary objective of this paper is to investigate the corridor of Eurasia High-Speed Railway Network from the governmental view of the Republic of Korea, whose High-Speed Train has been recently operated. The country is also expected to figure out the changes of Eurasia infrastructure system under the assumption that Trans-Korean Railway is connected to the Continent. As a result of research, the corridor connecting the TKR to TSR seems to be more attractive to the Republic of Korea than that of the TKR-TCR under the current economic and operational environments. However, even in a case, the railway linkage through the TSR between Europe and Asia should remain a supplementary means of the sea transportation route. Lastly, TSR may need a program of structural reforms, in order to continuously provide preferable services like the Pan-European Transport Network (PETN) which is currently initiated by the European Union, such as to improve outdated infrastructure (railway, bridges, signal systems, etc.), to simplify and to standardize the process of custom clearance and internal tariffs, and ultimately to construct a uniform management system for the corridor linking the TKR to TSR.

Compared with other transport means, safety and timeliness are the merits of railways. Unexpectedly when accident happens, much time and human strength are required to cope with the accident. And for swift recovery, systematic rehabilitation is needed. Recently using MTS(Moving picture Transmission System), we can perform accident rehabilitation and recording work efficiently. MTS is the device that transmits continuous picture information from accident field to control center. e are developing the appropriate system to railway situation to make use of the existing information communication technology, processing technology of video-tex, super high speed transmission technology through fiber-optic, copper cable and network description of information Technology, etc. If these communication-based can technologies are applied to railway system, railway managers can control the accident by inspecting the picture of accident field and can contribute to the safe train operation and the improvement of railway management. In this paper, we investigate the connecting methods when optical fiber is used for moving picture data transmission of train accidents, and its problems. And, we validate MTS's performance through about 28km section of field test.
