After the establishment of 'Staggers' Rail Legislation' in 1980, which established an atmosphere of free competition in rail freight transportation market, freight railway in America became larger and the proportion of freight railway in the market increased. In 2008, it took up 43% of the transportation market based on tonne/mile unit and the productivity of freight rail increased. On the other hand, in the case of Korea, the competing atmosphere is being set up under the influences of the renovation of the rail transportation industry in 2004. However, to make the rail transportation market more active and become more advanced, a lot of efforts are required to build a stronger foundation of free competition atmosphere. In this paper, we have deducted the political implications on the establishment of strengthened competition in Korean rail transportation industry from reviewing what kind of changes the rail transportation market in America went through and how it was developed. In this case, we have focused on the changes in industrial trend towards the restriction policy. Also influences of the deregulation policy after 1980 on the enhanced market efficiency were reviews.

Lightning induced faults accounts for more than 66% at the transmission lines of KEPCO. The lightning causes damages to power system equipments including transmission line, the shut down of electricity and the electro-magnetic interference. Because of this reason. we need the real time lightning information for the optimal operation of power system. And, it is required to obtain and accumulate the lightning current parameters for the insulation design. A lightning detection system, LPATS, has been operated since 1995 in KEPCO. For the improved detection efficiency, we had in stalled the new lightning detection network named as KLDNet in 2005. Also, we had developed the new software for the lightning parameters analysis and real time information service on the WEB. In this paper. we would like to introduce about the new system.

인터모달리티(intermodality)는 문전운송(door-to-door transport service)에서 적어도 이종(異種)의 운송수단이 통합된 방식으로 사용될 수 있도록 하는 운송의 특성을 가리킨다. 인터모달리티의 추진은 운송 및 물류 시스템의 효율성 제고뿐만 아니라 운송으로 인한 외부비용의 감소에도 유효하게 작용함으로써 그 중요성이 국제적으로 인정받고 있다. 최근 국내에서도 환경부하를 줄이고 지속가능한 운송체계 구축을 위해 인터모달 운송시스템 구축을 위한 정책을 추진하고 있으나 여전히 개선의 조짐을 보이지 않고 있다. 특히 육상운송에서 도로운송의 대체수단으로서 그 역할을 수행해야 할 철도는 각종 제약으로 인해 화주가 원하는 서비스를 제공하지 못하고 있어 대책마련이 시급한 실정이다. 본 연구에서는 지속 가능하면서 효율적인 물류를 실현하기 위해 인터모달 운송시스템 정비에 노력해 오고 있으며 특히 정보통신기술 등의 활용을 통해 철도 인터모달 통합운영체계 구축에 선제적으로 대응해 오고 있는 미국의 사례를 살펴봄으로써 국내 철도 인터모달 운송 시스템의 정비와 추진을 위한 제반과제에 대하여 검토해 보았다. Purpose : In this study, we have been trying to improve the intermodal logistics system to realize sustainable and efficient logistics. Especially, we will look into the cases of U.S. which has been preemptively responding to the construction of a railway intermodal integrated operating system through the use of information communication technologies and examine the various tasks for the maintenance and promotion of the domestic railway intermodal transportation system. Research design, data, methodology : The paper used a qualitative research methodology through the literature review. Results : In the U.S., information technology such as cargo identification, information systems for vehicle position tracking and monitoring, sensors and ITS have been important projects to improve the efficiency of intermodal transportation. Test and demonstration project have been carried out to identify the ITS techniques applicable to intermodal cargoes. As a result, the ITS architecture and its criteria have been set up for cargo identification technology that considers interoperability and security control. In Korea, it is necessary to construct a railway intermodal transportation system in terms of environment and logistics efficiency. For this, it is necessary to construct a real-time response system using system architecture setting for railway intermodal users, development of intermodal information system, interface development with other traffic information system, ICT. Conclusions : In Korea, measures are urgently needed that can provide transportation system and logistics service to meet the demand of shippers and to guarantee for social and economic growth. For this purpose, it is necessary to secure the accessibility, mobility and service improvement of the railway by securing the connection with other transportation and traffic information system. It is also necessary to develop railway intermodal transportation facilities over a long period of time, and to access them through a nodal point of view, but this requires time and costly constraints. This disadvantage can be solved by securing the flow of railway cargo without interruption by utilizing information technology such as ITS and ICT. It also has the advantage of contributing to the improvement of the environment by increasing the use efficiency of railway freight stations, vehicles, and transportation infrastructure. This study of intermodal transport in the United States is important that provides opportunities to assess current information and communication technologies and to identify issues to be studied in the future, as well as to anticipate changes and trends in the operation of domestic intermodal transportation systems.

Big Data Creation Process and Measures for Utilization: Focusing on the Transportation Sector

우정욱(Jungwouk WOO) 제주대학교 관광과경영경제연구소 2021 産經論集 Vol.41 No.3

Transportation big data is not limited to the transportation sector, but is a useful resource that will bring innovation to all aspects of our lives in the future, and various R&D for its utilization is currently in progress. However, the current level of utilization of transportation big data is very limited under the existing legal system. In this study, we will investigate the meaning and problems of the use of big data in the transportation sector, and investigate the improvement tasks to expand the use of big data. Research Design, Data and Methodology: The paper used a qualitative research methodology through the literature review. In this study, first, the definition and creation process of big data were studied. Second, the significance and problems of applying big data in the transportation sector were studied. Finally, the current status of research in the transportation sector using big data was investigated, and the tasks to be improved in the process from collecting transportation big data to analysis were reviewed. Results: Big data means creating new value by fusing data collected from different purposes. In the case of using big data, the transportation sector can establish more accurate and detailed transportation policies in basic data investigation, identification of phenomena, and prediction. In order to expand the use of big data, it is important to consider who owns it, what it was collected for, what the format of the collected data is, and what should be done to use it. Conclusion: Big data is a derivative thing, but it is becoming important enough to determine the success or failure of a country depending on how it is used. However, problems such as data errors or invasion of privacy that may occur when using big data are expected. This is not just a problem in the transportation sector. When using big data, there are many problems to be solved, such as data ownership, Big Brother problems, and the implementation of smart mobility. If the advent of the big data era is taken for granted, the task from now on is how to solve these problems and share their values.
