Over 80% of Korea's cargo transport relies on public roads. Such over-reliance has created a range of social problems including environmental damage. Korea thus faces an urgent need to establish an alternative mode of cargo transportation. In view of the changing international logistics environment, railway is clearly a superior mode of transport. The prerequisite task today for Korea is to enhance the competitiveness of inland railway by switching to railway and spurring new demand for cargo. This study examines inland railway cargo transport from the demand perspective. Specifically, through the use of a survey, the study identifies key factors influencing the decisions of container shippers regarding the use of railway for cargo transport. The survey responses were statistically tested using Smart PLS structural equation modeling. The results indicate that attitude toward railway use had the strongest influence on choice, while the key variable affecting attitude formation was cost.

The cost of domestic container transportation is higher than international sea transportation and it cannot meet the needs of customers either. However, domestic carriers try hardly nothing to improve the carriage system. Especially, the inland transportation connecting Busan port is not receiving a careful study in spite of the importance and urgency now. This paper reviews intention of forwarders, shipping companies, and transport companies conducting a questionnaire and analyse the preferences of transportation modes amongst existing highway, railway, coastal shipping and inland waterway. Its aim is to analyse which factors affect freight agents to choose particular mode.

This study analyzes the basic characteristics needed for motivating modal shift from truck to rail. The object of the study is to consider the resistance factor for container transported inland and the object point is the transfer node where modal shift occurs. The main contents of the study are as follows. First, the study looks at what shippers, engaged in inland transport of container, think of current transfer node environment. From this, the study analyzes what resistance factors are attributable to the lack of motivation in modal shift from truck to rail. Second, the study estimates mode choice models in which the resistance factors at transfer node are applied. Also by using this, the study draws out elasticities, and analyzes characteristics of resistantance factors in modal shift. Third, as its result, the study suggests methods to promote modal-shifting container transport from truck to rail.

This study assesses the appropriate amounts and applicable ranges of travel time values for freight transport modes in Korea. The findings suggest that it is possible to determine appropriate sizes and applicable ranges of travel time values of goods set for road transport mode (i.e. truck), whereas those for railway, inland waterway, marine, and air transport modes are not as easily estimated. The adequate travel time value for trucks is 20,000won/vehicle hour, and the application range of travel time value of trucks is 17,000~23,000won/vehicle hour considering other variables. The most adequate estimation method of determining the travel time value for road transport is the wage rate method, whereas the marginal rate of substitution method is more rational for railway, inland waterway, marine, and air transport modes considering the application purpose and characteristics of the goods transported.

우리나라의 '국토 종합 물류 네트워크' 구축에 기존의 항만, 도로, 철도 중심의 물류 체계에, 국토의 삼면이 바다로 둘러싸여 있으므로 주요 항만과 연계하는 국토 내륙은 물류 수송체계와 주요 강(江)이 수로(水路)유역의 광역권 및 주요 도시가 연결되어 있기 때문에 수로를 이용한 물류수송체계와 통합한 종합적인 국토 물류 수송체계에 대한 연구가 필요하다. 이 연구에서는 파워심시뮬레이션 기법을 이용하여 우리나라의 수로운송을 통한 국토종합물류체계망 구성방향을 도출하였다.

Since ports play a role of gateway to the sea and hinterlands, it is essential to analyse the networks of shipping and inland when evaluating the function and development of a port. The container port of Gwangyang, starting to operate its facilities in 1998, has developed itself as a hub port. Using the data of shipping schedules of Korean ports and the measurement of centrality in sociology, this study analyses the process of world-wide shipping network expansion in Gwangyang and concludes some implications including earlier development of shipping networks due to incentives to shipping companies. Although Gwangyang port also has been expanding its inland network through developing trucking, railway transport, and coastal shipping, it has weakness in inland network as in the cases of interruption in 2004, resumption in 2009 and re-interruption in 2012 at coastal shipping. In 2000s the expansion of shipping and inland networks at the newly built container ports such as Pyungtaek, Ulsan, and Gunsan has enticed the competition among Korean ports at each hinterland. Nevertheless, the operation of Gwangyang container port is considered to affect indirectly the relocation of some manufacturers including Samsung Electronics. Studies on interrelation between development of container port and geographical demography of manufacturers are needed to assess the effects of container port on regional economy.

The inland logistics center is a large scale of logistics facility that enables roads, rails, ports, and airports to carry out chained-transports and combined-transports, and the logistics center are established at the main logistics posts in order to reduce the cost of transport by mass transportation. However, it is expected that the capacity of Euiwang ICD, the only inland logistics centers in the capital area, will reach its limit before 2015, so it is required to establish another stations or to improve the existing facility. Especially, in case of Euiwang ICD, the expansion of the center is not possible because of its position, so it is required to establish new logistics centers in other places in order to raise the capacity of transport. Therefore, this study suggests to establish new metropolitan logistics centers on the western coast line in order to solve the problem of shortage of tract capacity that is brought on by the newly established inland logistics centers on the axis of the western coastline (Song-san Station and An-jung Station), and analyzes how the new logistics center will distribute railroad cargoes. By these, this study contributes to reduce the cost of transport by providing smooth railroad transport service.

With development of port industry, inland transportation was also the developed. Connecting port with inland becomes more and more important. So studies about cargo flow from ports to regions are actively in progress. But freight statistics from regional to national has a problem that do not comprehend exactly with freight flow. Also these statistics don't reflect characteristics of multimodal transportation system. The objective of this paper is to analyze freight flow of container with the introduction of P/C and rebuilding freight statistics from regional to national scale.

It is estimated that the potential of Chinese market is infinite. The success of Chinese economic reformation is generating the high economic growth in China. China is a rising logistics market as its growing throughput and port expansion but China's railway transportation system is not well-linked with ports. China built TCR(Trans-China Railway) which is across the Chinese territory and connected to as far as Europe. With this mode, it is possible to place more overseas freight and meet more customers' needs. Lian yun gang is a city on the East coast of China where the commencing station of TCR is located. This paper reviews the present conditions of Lianyungang and presents the development direction of the city to become a logistics point.

China has experienced rapid economic growth and burgeoning trade since it began economic reforms and an opening policy. With this the amount of marine cargoes between Korea and China had been increased Recently this increasing rate of cargoes, the development of the Yellow Sea Sub-Region and the change of the Northeast Asian logistics network have acted as important factors of Korea's strategy to be the Northeast Asian logistics hub. This paper analyzes China's inland transport network to offer basic understanding on transport and logistics network in China. Therefore, the outcomes of this paper could be used as basic materials to further transport and logistics cooperation between China and Korea and to developing a more realistic plan to complete Korea's Northeast Asia logistics hub strategy.
