Busan transport hub development for trans-korean railway transportation

The integration of the railways of South and North Korea will make it possible to form an international Eurasian transport corridor and ensure the transportation of goods produced in the Republic of Korea by rail. Today, South Korean cargo owners, due to the island situation, use mainly sea transport. The organization of transportation on the Trans-Korean Railway with access to the Trans-Siberian Railway and the railways of China and Mongolia will give advantages to shippers in terms of cost and time of cargo delivery. The implementation of the project on the reunification of the Trans-Korean Railway will lead to an increase in the volume of cargo and container transportation, including in rail-sea communication. In the Republic of Korea, the main transport hub is the port of Busan, which is served by rail and road transport. The Busan transport hub includes two seaports - the new and old Busan ports, railway stations serving the container terminals of the port, as well as rear terminals to which container delivery is carried out by road. Every year, the share of rail transport for the import and export of containers to the terminals of the port of Busan is less than 7 % and continues to decrease. This dynamic is associated with the presence of infrastructure, economic and technological problems of interaction between rail and sea transport in the port of Busan. The subject of this study is the analysis of the processes of interaction between different modes of transport in the new port of Busan. The purpose of the work is to develop measures to increase the capacity of the railway component of the Busan transport hub for the organization of trans-Korean transport within the framework of the Eurasian transport system. In this paper we used theoretical methods of research, including a systematic analysis and synthesis of information. As a result of the analysis of the technical equipment, operating technology and the existing railway infrastructure of the New Port of Busan, the presence of «bottlenecks» in the functioning of the «railway - seaport» system was revealed, which hinder the effective process of container transportation. The paper considers infrastructure, technological and organizational measures to increase the processing capacity of Busan transport hub facilities. The implementation of the measures under consideration will require time to change and restructure the system of interaction of transport in the process of container transshipment. It is necessary to determine the stages of infrastructure changes based on the forecast of future traffic volumes, including using simulation modeling.
