In light of the growing traffic congestion problem and congestion cost, the container transport by railway has to be increased. The freight transport by railway can have decided advantages over trucks in terms of energy efficiency, emissions and cost for certain freight movements, just as transportation in the metropolitan region can have great advantages over driving truck. But the freight transport by truck should gain significant mobility benefits from a freight railway system. Thus, the DMT(Dual Mode Trailer) transport system which is coupled railway transport advantages with load transport advantages has been developed and used in the european countries. The DMT transport will therefore serve the areas required by transport organizers. The purpose of this paper is to estimate economical feasibility analysis for development of DMT transport system. Consequently, this study analyzed the characteristics of the DMT system. The horizontal load.unload system is being considered as an adoptable DMT system in consideration of the situation in Korea.

The article suggests criteria of dividing transport systems into systems of limited and open access. Possibilities of implementing principles of the open access in conjunction with the adaptive control at the railway transport have been analyzed. The author makes a grounded conclusion that the development of transport systems based on the open access and adaptive control can play a positive role in overcoming the global instability of the economy and form prerequisites of its stable grows.

The objective of this paper is to measure the relative technical efficiency of Korean railway transport service. Previous studies on the efficiency in Korean railway service have carried out before the structural reform of Korean railway industry in 2004, whereas this study used the latest data which reflected the impact of reform. We analyzed the efficiency in Korean railway transport by means of measuring the technical efficiencies of other countries, these were estimated with data envelopment analysis. DEA has gained great popularity in measuring efficiency in transport industry, school, government, hospital and so on in recent years. This analysis could serve as peer to help improve performance of the railway management and operation.

Recently study on passenger' activities found that many passengers were ride in kinds of transport, e.g. car and railway while business trip. Usually choice of transport is determined by the transportation of passengers, depending on the purpose of travel. A study was therefore set up to study how efficient influence the transports about business trip. The study involved 4 subjects (4m) which divided into four groups during two day. We evaluate about the transport productivity by each day by using the car and railway. The transport productivity of car and railway was valued in HRV and Stroop Color Word Interference Test. The results showed significant differences between the car and railway. The subjects reported that use of railway is greater transport productivity than the car.

The integration of nanoparticles into various industries has spurred interest in understanding their impact on logistics and transportation systems. In this study, we investigate the effect of nanoparticles on the economic aspects of railway logistics transport using a mathematical model. By incorporating factors such as transportation costs, time efficiency, and environmental considerations, we aim to assess the overall economic feasibility of integrating nanoparticles into railway logistics operations. Through mathematical modeling and analysis, we explore how the introduction of nanoparticles affects cost-benefit analyses, resource allocation, and decision-making processes within railway logistics. Our findings provide valuable insights into the economic implications of nanoparticle integration in railway transport, offering potential strategies for optimizing logistics operations and enhancing overall efficiency and sustainability.

본 연구는 우리나라 무역항으로 유출입하는 벌크화물의 철도운송특성을 분석하였다. 무역항 배후에 입지한 화물역의 벌크화물 운송을 실적자료를 이용하여 분석하고 시사점을 도출하였다. 연구 결과 무역항 배후 철도역의 벌크화물 처리량은 감소추세이며 공로운송에 대한 경쟁력도 확보하지 못하는 것으로 나타났다. 원인은 철도운송의 경쟁력 저하와 더불어 항만인입선이 건설되지 않은 새로운 무역항의 영향이 크게 작용하는 것으로 파악되었다. 따라서 새로운 무역항과의 철도연계 강화 노력이 요구된다.

본 연구의 목적은 우리나라 철도수송의 효율성을 측정하는 것이다. 우리나라 철도수송의 효율성에 관한 기존 연구들은 2004년의 철도산업 구조개혁 이전에 수행되었지만, 본 연구는 이의 영향을 반영하는 최신의 자료까지 포함하여 효율성을 측정하였다. 측정기법은 다른 국가 운영회사들과 비교하여 상대적인 효율성 수치를 산출해주는 자료 포락분석(DEA) 기법을 이용하였다. 분석대상은 2000년${\sim}$2006년 동안 22개 국가 철도운영회사가 제공한 철도수송 서비스이다. 분석 결과 우리나라 철도수송은 타 국가와 비교하여 그동안 효율적으로 운영되고 있고, 2004년 이후 생산성이 증가하고 있는 것으로 나타났다.

There are a close relationship between natural disasters and train safety. So it is very important to guaranty train safety using reasonable rail-transport operation control against disasters. Therefore, based on the past record of rainfall at failure, rail-transport operation control for railway embankment under rainfall was set up. After slope check list at home and abroad had been analyzed, new slope check list was suggested and site investigations were carried out using this check list. In order to evaluate the stability of railway slopes under rainfall, explanatory variables and subordinate variables were selected for multi-variate analysis and critical rainfall was defined by statistical process. Rail-transport operation control including regional and geological properties was suggested by analyzing the critical rainfall and rail-transport operation control in other country, and this will be a good tool to control train speed under rainfall and to secure train safety.

국내 화물운송의 80% 이상을 분담하고 있는 공로중심의 내륙운송체계는 환경문제를 비롯한 다양한 사회적 비용을 야기시키고 있어 다른 운송수단으로의 화물전환이 요구되고 있다. 특히 변화하는 국제 물류환경을 고려해볼 때, 철도는 지속가능한 대안적 운송수단임에 분명하며, 도로화물을 철도로 전환시키고 새로운 수요를 창출하여 내륙철도의 경쟁력을 확보하는 일은 미래를 예측하고 대비하기 위한 필수적 선행과제가 되었다. 따라서 본 연구는 내륙철도 이용 확대를 위하여 컨테이너화주를 대상으로 컨테이너 화물을 철도로 유인하기 위한 핵심 요인을 밝히고자 설문조사를 실시하고 SmartPLS구조방정식모델링 분석기법을 통하여 결과를 도출하였다.
