Transportation cost takes a major portion on logistics cost. The reduction of transportation cost is a key issue to achieve national competitiveness and logistics cost reduction. And railway must play a important role to shift from road freight transport to environment-friendly transport. There are many idle freight cars in railway freight transportation and they give rise to inefficient operation of freight car. It is well known that the main reason of idle freight cars is unbalanced demand according to direction. In this study, we analysed the current status on idle freight cars in railway at the level of daily data. This results help follow-up research to cut down idle freight cars in railway.

Travel time reduction is a benefit in economic analysis. Freight transportation time reduction benefits influence the logistics industry. The objectives of this paper are to estimate the Value of Time (VOT) for transportation time reduction with logit methodology. The data of Gyeonggi-do's domestic road freight transport in 2007 are used. VOT was estimated for five commodities. An average VOT of 19,946 won/vehicle-hr was calculated; transport of electronic parts had the highest VOT. This study will help provide direction for improving Korea's road infrastructure for freight.

The efficiency and effectiveness of freight transportation within and across Northeast Asia playa key role to achieve competitive advantages against other competing hubs in this area. However, the majority of local freight has been carried by ground transportation and the share of costal shipping has been decreasing for its transportational complexity and poor cargo works. In this paper, we discuss the prerequisites of efficient cargo linkage system from the perspectives of road, rail, ocean, and the service providers. Specifically, we identify that the balanced capacity of road/rail transportation system with costal freight system is a crucial component for facilitating coastal shipping. Other requirements such as the efficient on-dock container yard (ODCY), dedicated ports and ships, and the service provider of door-to-door transportation for short sea shipping are highlighted in order to secure the serviceability and availability of streamlined costal shipping. Further, we elaborate these requirements to facilitate costal cargo shipping in Korea.

Road freight transport industry in Korea contains many and complicate problems such as over supply of the vehicle caused by rapid policy changes, illegal multilevel transactions, poor truck drivers working environment, lack of road freight transport related statistics and so on. Korean government has developed various logistics industrial policy trying to solve these problems in various ways. However, the relationship among the problems and action plans has been more and more entangled since the part of suggested policies have made another perverted problems. These complex structure of the toad freight transport industry in Korea makes difficult to identify and to solve the problems. Causal map method helps to give a clean picture to understand the complex industry at a glance. This study contributes for visualization of the causal relationships among the existing problems and related policy issues in the road freight transport industry in Korea by causal map. This study could be helpful to develop the actual road freight transport industrial policies including the illogical multilevel and unfair transaction in Korea.

Global warming has become one of the most important social responsibilities. After Kyoto protocol for greenhouse gas reduction by climatic change convention came into effect, developed countries are presenting various policies to reduce greenhouse gas that is produced in transport field. One of those policies is modal shift that change from road freight to sea, inland waterway and railway transportation that is eco-friendly. Because increase of road freight brings about road congestion and accident, logistics cost, air pollution and green house gases. Railways are superior to all other modes of transport in mass transportability, high speed, timeliness, safety and environmental-friendliness, but the railway industry has been pushed behind in competition. In developed country's government actively promoted relevant legislation, policies, and countermeasures known as modal shift policies to shift freight transport from road to large volume mode such as railway and ship. In this paper, we discuss the current situation in modal shift, compare it with cases in other countries EU and Japan, identify problems in Korea, and propose the following ways to enhance competitiveness of rail freight.

Railroad is considered as an eco-friendly transportation mode because it emits lower greenhouse gases and air pollutants and consumes less energy compared to trucking. To promote rail freight, many countries have implemented various policies, while South Korea has implemented few substantial policies. This study aims to compare and analyze rail freight policies of various countries in order to suggest policy implications to South Korea. We analyze relevant policies of 9 countries; these are classified into 5 categories, and we provide policy implications for facilitating rail freight infrastructure and equipments, grants for the transportation cost using freight rail, and road freight restriction policy.

With increasing global concerns for environmental impacts, efforts have been made to encourage a modal shift from road freight to an eco-friendly transport system such as rail freight. In Korea, the government has set master plans for a green transport system but has not taken any substantial action to promote rail freight transport. In developing policies and actions to promote rail freight, quantitative studies on environmental impacts among transportation means are essential. This study examined the air pollutant emissions and greenhouse gas (GHG) emissions per unit freight transported by road and rail, respectively. To improve the accuracy, we analyzed emission data and freight transport mileage of rail freight considering diesel locomotives and electric locomotives separately. The results show that unit air pollutant emissions (except SO2) from road freight are about 7~15 times more than those from rail freight. In addition, the GHG emission unit of road freight is about 4 times higher than that of rail freight.

This study aims to assess the potential competition among road, rail, and coastal transport under various scenarios concerning the future inland container transport systems in Pusan-KyungIn corridor. For this SP approaches are adopted to collect data from shippers and carriers, and multinomial logit models are estimated at disaggragate level. The results of the analysis indicate that the SP data are reliable, and that the mode choice models estimated are valid. The results also indicate that the most effective policy to divert the freight volume from road to other modes is to reduce freight rates for the railway, and is to transport time for the coastal water with improved reliability.

Due to the fact that high speed railroad will be opened to traffic and TSR and TCR will be connected to Korean railroad network in near future, the efficient operation methods of Railroad freight transportation have been embossed as a matter of concern. But, it is true that the present level of our railway infrastructures and operation systems are still low. This study examines the freight transportation system and introduces new logistic service systems including network strategies and terminals which are haying developed overseas to increase the efficiency of existing railroad transportation system. In case of giving careful consideration to the new methods, it is expected that the high developed freight transportation systems will be applicable to our country.
