Honam area is one of the under-industrial areas in Korea and because of this it has low weight in the total container transportation in Korea. Also the railway distance from honam area to the main container ports like Busan port and Gwangyang port is so short that the portion of rail container transportation occupies about 10 percent in total container transportation amount in Honam area. But on the contrary of those situations, 1st step Jangsung inland container depot (ICD) was finished as one of the main logistics facilities in Korea and 2nd Jangsung inland container depot is under construction. To promote rail container transportation in Honam area which has shortage of container transportation demand, it is necessary to give adequate transport service to the client. So, this research studied some methods for promoting rail container transportation in Honam area. The subject of survey is freight agent and survey items are selected to find the present situation of rail container transportation in Honam area. And from the survey results various strategies will be suggested to promote rail container transportation in Honam area.

In these days, rail container service is being more important because it has relatively simple network. In addition, small lot sizes of shipment, frequent shipment, and demand for flexible service are important characteristics in rail container transportation. Efficient container operation at terminals is important in reducing transportation costs and load/unload time. This paper describes the assigning track of freight trains in the railway freight terminal. The paper addresses the operational requirements and facility restrictions to construct a mathematical model for track assignment. In addition, it suggests several types of objectives for the model.

철도-공로 복합화물운송은 최초출발지에서 최종목적지까지 화물을 수송함에 있어 철도와 화물자동차를 연계하는 운송시스템이다. 철도-공로 복합화물운송에서 공로(화물자동차)의 역할은 집배송 기능으로 전체 운송과정의 경쟁력에 중요한 영향을 미친다. 본 연구는 철도-공로 복합화물운송의 대표적 화물인 컨테이너를 대상으로 집배송 부분의 효율성을 제고시키기 위한 운송전략을 개발하고 평가하는 데 목적이 있다. 이를 위해 컨테이너트럭의 운송거리 최소화를 지향하는 전략과 고객에서의 대기시간 최소화를 주목적으로 하는 전략 등 2개의 집배송 개선전략이 개발되었다. 개발된 전략들은 파리수도권의 실제 집배송망에 적용되어 그 효율성이 비교, 평가되었다. 기존 집배송방식과의 시뮬레이션 비교결과 제안된 전략들이 다양한 성과지표에서 상당히 효율적임이 입증되었다.

In 1991, Korean government decided to establish the Inland Container Depot for activating transportation of rail freight container and encourage the effectiveness of intermodal transport system. Therefore, the Ui-Wang ICD has been built in Kyonggi province and began to operate in 1993. However, Despite of original purpose of the Inland Container Depot, rail freight volume at public CY(Container Yard) in Ui-Wang ICD has been recorded very low. This paper deals with the promotion strategy for rail transport in Ui-Wang ICD. The relationship of conflicts between the rail-oriented transporters and road-oriented transporters in Ui-Wang ICD have been found through the TOC thinking process and some solutions are suggested. Some undesirable effects in operation of Ui-Wang ICD are listed and current reality tree(CRT) has been established and future reality tree(FRT) which includes some injections to active the rail transport in ICD has been recommended based on CRT. In order to make good solutions the situation in Busan-jin station ICD known as similar to Ui-Wang ICD has been analyzed.

본 연구는 공로에서 철도로의 모달 쉬프트를 활성화 하는데 필요한 기본 특성을 조사하고 분석하였다. 연구의 대상 화물은 국내에서 내륙으로 운송되는 컨테이너이며, 연구의 대상 지점은 모달 쉬프트가 이루어지는 환적노드를 중심으로 하였다. 연구에서 수행한 주요 내용은 다음과 같다. 첫째, 컨테이너 육상운송을 하는 화주가 생각하는 환적노드의 운송환경에 대한 인식을 조사하였다. 그리고 이로부터 공로에서 철도로 모달 쉬프트가 활성화되지 않는 저항요인을 분석하였다. 둘째, 환적노드의 저항요인을 반영한 운송수단 선택모형을 추정하였다. 그리고 이를 활용하여 탄력성을 도출하고 모달 쉬프트 저항 요인별 특성을 분석하였다. 셋째, 연구에서 도출된 결과로부터 컨테이너 운송수단을 공로에서 철도로 모달 쉬프트 시키는 방안을 제시하였다.

Rail transportation terminals play an important role in inland transportation systems, because the operation productivity in the terminals significantly influences the efficiency of the whole transportation systems. This paper addresses a design method of a real rail terminal that satisfies a pre-specified throughput capacity. In order to construct high performance rail terminal, it is shown how design parameters can be estimated systematically. Examples of the design parameters are the number of transshipment tracks, the number of rail cranes, and the number of internal trucks. These design parameters are estimated by using simple equations and the validity of the values of these parameters are tested by using simulation. Furthermore, some iterative correction procedure, which uses the simulation technique and the equations alternately, are proposed.

항만구역에 있는 철도시설 중에서 비교적 규모화 된 항만철송장은 현재 부산항지역과 광양항지역에 배치되어 있다. 항만철송장은 철도물류의 시종 역할을 하는 주요한 기능이나 현재는 선로 배선 규모, 하치장 면적 등에 있어서 철도의 특성을 반영하지 못하여 비교적 활성화 되지 못한 상황이다. 또한, 활성화 되어 있더라도 이미 처리용량이 포화상태에 이르러 더 이상 철도수송물량을 증대하기는 어려운 상황으로 철도컨테이너 수송사업 활성화를 위해선 근본적으로 항만철송장 시설규모에 대한 재산정이 매우 필요한 상황이다. 본 연구에서는 이러한 철송장의 시설배치 상 문제점 해결을 위해서 최근 개장한 부산신항의 철송장을 중심으로 문제점을 분석하고 해결할 수 있는 방안에 대해 살펴보았다.

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.

The Port of Pusan, the largest port in Korea, handled 23% of total sea borne cargo movement, 14% of imported cargo, 58% of exported cargo and 95% of container cargo in 1989. Also the port of Pusan has been played a key role in handing container cargo throughout the last 10 years. The paper is aimed to survey the effect of sea borne cargo movement to urban transportation, that is, to find traffic volume arising by general/bulk cargoes through the port and to estimate vehicle rated of container tractor tailer on the roads between terminal including conventional piers and ODCY, and finally the following results are obtained. (1) AADV of truck to transport general/bulk cargoes are 6,322 units in 1989,and routes penetrate into the center of city and pass through the most of urban arterials. (2) In the container transport, if HVEF is adopted to 3 of tractor trailer, AVR in each transport freeway 13.7%. (3) IF HVEF is adopted to 6 of tractor trailer. AVR are as follows: BooDoo-Ro 44.1%, WooAm-Ro 39.3%, SooYoung-Ro 17.8%, Urban freeway 20.3%. Based upon these results, the following suggestions were drawn : o ODCY scattered around the city should be unified in a few groups to raise port productivity. o Rail service for inland container transportation should be escalated to relieve urban traffic congestion. o Coastal feeder service between terminal and hinterland should be studied to restrict the penetration of container tractor trailer into the central parts in the urban areas. o Exclusive freeway system for effective container transportation should be implemented to reduce urban traffic delay.

This paper introduces some of the developments related to the handling equipment in container terminals and various new conceptual handling systems that have been proposed during the last several decades. The basic ideas behind the previous equipment improvements are analyzed to identify future directions that can be used for devising new handling systems. The handling systems in the container terminals include a quayside handling system, transport system, and yard system. In response to the deployment of mega-sized vessels for container transportation systems, productivity improvement has become one of the most urgent issues in the container terminals. This paper analyzes the previous improvements made for achieving higher productivity in the three subsystems of container handling. Some conceptual handling systems are introduced including the linear motor conveyance system (LMCS), automated storage and retrieval systems (AR/RS), overhead grid rail (GRAIL), SPEEDPORT, SuperDock, the automated container system by ZPMC (ACS-ZPMC), and AUTOCON.
