The logistics industry is changing with the diversification of demand and related technology development. Thus, the transportation system is also changing to social problems and environmental damage, and the importance of rail freight is increasing with changes in the international logistics environment. This study analyzes railway freight competition structure using freight volume and suggests improving the competitiveness of railroad freight. To achieve the research purpose, this study was conducted using the Hirshmann-Herfindahl Index(HHI) and Location Quotients(LQ) method. As a result, the concentration trend of railway trends has increased from 0.213 to 0.238 during the last 9 years, and LQ analysis has enabled the identification of local competition lines by item. The study result confirmed that policy measures on railway freight system, railway infrastructure construction and railway operation are necessary to enhance railway competitiveness.

Successful market adoption of rail freight transport innovations that might offer opportunities for market share increase is the focus of this paper. Firstly, seen from a theoretical point of view, it is not incremental innovations but radical organizational and transformation innovations that are likely to increase the market share of rail freight transport. Secondly, the particular inovations that offer some success potential for market adoption are: dedicated infrastructure, the fixed timetable, locomotive upgrades, and INTERFACE. Thirdly, unfortunately, the opportunities to increase the market share of rail freight transport appear to be limited.

This study tried to suggest a new direction of rail freight pricing in Korea. Determinant factors of rail freight fare are collected and pricing principles are introduced. Marginal social costs are to be fare of rail freight in theory and those costs should be estimated in the near future. From the market pricing of North American rail freight carriers we can find a direction of future pricing and from the EU efforts to estimate social marginal costs we can also find research agenda.

Urban areas face congestion problems that diminish personal mobility and freight-transportation productivity. An increasing number of experts suggest that separating freight traffic from passenger traffic makes sense in terms of economics, the environment, and safety. Some experts suggest that underground freight transportation are the solution. The objective of this paper is to review the potential benefits and limitations of freight pipelines as a viable mode of cargo transport that can alleviate congestion on urban highways.

Recently, freight cars for diverse purposes were developed to increase the speed of freight car in conventional line. The welded type bogies are applied to these vehicles like container car, gondola car, hopper car, etc. This study was focused on the dynamic characteristics and the stability of freight car to guarantee the running safety. We have conducted the running tests of freight cars in conventional line and described the test results in this paper.

Freight Forwarders is very important of logistics industry but it still has a lot of problems which have to be improved. The purposes of this study are realizing the current state of freight forwarders and suggesting the developing strategies. It is necessary to make proper size, develop of human resource and construct of information system for development of freight forwarders. Furthermore, it requires more efforts of company and government such as support of tax, support of investment in freight forwarders.

전 세계적으로 환경에 대한 관심이 높아짐에 따라 세계 각국은 도로중심의 운송체계를 철도 등 친환경 교통체계로 전환하고자 하는 움직임이 증가하고 있다. 우리나라도 도로화물수송의 철도전환을 도모하고자 하고 있으나 실질적인 노력은 부족한 상황이다. 화물철도와 같은 친환경 수송수단에 대한 지원정책 마련을 위해 무엇보다 필요한 것이 바로 도로대비 철도의 친환경성에 대한 정량적 자료이나 이에 대한 연구는 부족한 상황이다. 따라서 본 연구에서는 철도와 도로의 화물수송시 배출되는 환경오염물질 및 온실가스 배출 원단위를 산정하고 이의 비교검토를 진행함으로써 철도화물의 친환경성을 제시하였다. 특히 디젤기관차와 전기기관차의 대기오염물질 및 온실가스 배출량이 상이하므로 이를 구분하여 산정함으로써 보다 현실적인 친환경성 비교분석을 수행하였다. 분석결과 도로화물의 단위수송 당 대기오염물질 배출량이 SO2를 제외하고는 철도보다 7~15배 가량 높은 것을 확인할 수 있었다. 또한 온실가스의 경우 도로화물이 철도대비 약 4배 수준의 온실가스를 배출하는 것을 확인할 수 있었다.

The core decisions of bulk shipping businesses can be summarized as the timing and the choice of period for which carrying capacity is traded. In particular, frequent decisions to trade freight either with repeated spot transactions or with a one-off long-term deal critically impact business performance. Even though a variety of freight trading strategies can be employed to facilitate the decisions, chartering practitioners have not been active in utilizing these strategies, and academic research has rarely proposed applicable solutions. The specific properties of freight as a tradable commodity are not properly reflected in existing studies, and limitations have been reported in their application to the real world. This research focused on the establishment of applicable freight trading strategies by taking into account two properties of freight: time perishability and term-dependant pricing. In addition to traditional trading strategies, artificial neural networks were applied for the first time to the test of freight trading strategies. The performances of the trading strategies were measured and compared to produce a remarkable outperformance of the ANN. This research is expected to make a significant contribution to chartering practices by enhancing the quality of chartering decisions and eventually enabling the effective management of freight rate risk. In addition to methodological expansion, the result will propose a way to approach the controversial issue of freight market efficiency.

Recently, in order to improve the efficiency of freight transportation on existing lines, a new freight train model is needed to develop urgently. The weight balance of the cargo for the freight vehicle is very important for the stability of the running train and the safe transportation of the cargo. For achieving the cargo weight balance, we proposed a Cargo Balancing Control(CBC) system on the Freight vehicle equipped in between under frame of car body and bogie system. The Cargo Safety Monitoring(CSM) system was designed to supervise status of the Cargo on freight train. The monitoring system can display real time status data from sensors and various signals effectively. We suggested that this paper is a very useful approach for keeping the safety of running freight trains on existing lines.

최근 친환경운송수단인 철도의 역할증대 필요성이 제기되고 있으나, 국내의 경우 화물운송에 있어 철도의 역할이 오히려 감소하고 있는 실정이다. 본 논문은 국내 철도화물운송증대를 위한 지원제도 개선방안을 제시하는 것을 목적으로 한다. 우선 국내 철도화물운송의 현황 및 지원여건을 살펴보고, 철도화물운송에 대한 국가의 지원논리를 제시한다. 또한 영국과 스위스 등 유럽의 철도화물운송정책의 검토 및 국내 관련 기관/업체 인터뷰를 통하여 철도화물운송 증대를 위한 제도개선방안을 도출하고 이를 평가한다. 궁극적으로는 철도화물운송증대를 위하여 가장 합리적인 방안으로 판단되는 철도물류시설 및 장비확충 시 지원을 위한 구체적인 정책방안을 제시한다.
