The application of spatial information has drawn significant attention from a wide range of industries. Railway spatial information facilitates the cooperation among related parties and improves the efficiency of asset management and operations. This study proposes the structure of Railway Object IDentifier(ROID) on railway spatial information. Current facility management and train operation are based on relative positioning system. Despite many advantages, relative positioning system causes serious problems such as the entire reconfiguration of positioning in the case of line change. Another major concern is the interface compatibility between individual facilities with different relative positioning. ROID based on absolute positioning addresses these issues, allowing the information exchange and convergence between independent parties. This study proposes ROID based on OID standard with object IDentifier and service object-oriented reference system. Our ROID employs the absolute positioning and the unique identifier, maintaining the compatibility with existing management system.

In this paper, I illustrate the situations and problems rail industry is faced with. The rail industry has been suffering deficiency in investment with low technical level. Lacks of strategic marketing plans and low competitiveness in the industry led to a small portion of modal share, estimated at 12.6% in 2001(person base). Recently, rail industry has caught up with the current flow of changes. For example, a prototype of Korea high speed train had been manufactured to be successfully tested on commercial track. And the amount of rail investment increased gradually. The rail industry of EU nations, America, Japan reveals good outcomes, which keeps the balance in the black thanks to growth of investment in rail and high technical level. I have come up with some ideas for improvement, which I believe will be helpful to lead the rail industry. First, I suggest the upbringing of rail industry and technology on a national level. Second, expanding the rail network with the rail modernization. Lastly, I think it is crucial to establish a law and institution before we advance into overseas markets.

철도는 1899년 9월18일(노량진∼제물포)개통된 우리나라 최초의 대량교통수단임. 우리나라철도부설은 일본에 의해 대륙진출의 수단으로 이용된 타율적인면이 강했음. 그러나 호남선부설등에서는 우리민족의 자력적인 철도건설노력도 보였음. 대부분의 철도망은 식민지시대에 완성되었고, 철도네트워크는 경부선과 호남선, 경원선, 경의선을 중심으로 X자형으로 이루어져 있으며, 전쟁이후 우리나라는 산업선의 발달, 도시철도의 탄생등 주요한 교통수단으로 발전을 거듭해 오고 있음. 1960년대 중반이후 철도의 분담율이 저하되었는데 이는 자동차의 발달에 기인했다고 할 수 있으며, 이와같은 추세는 세계적인 추세였음.

Development of a train wireless signal control system using LTE-R technology is expected to have a great ripple effect to the existing signal control market. To make inroads into the international market, it is an urgent issue to practicalize the train wireless signal control system. Because it will require a huge budget to commercialize the wireless signal control system, it is necessary to analyze the feasibility beforehand, with a consideration of the domestic and foreign marketability and the impact on related industries. This study investigated the effect of the practicalization of train control system on future railway and national industrial sectors. We suggested the establishment of a framework for economic feasibility analysis, one that can provide criteria for opportunistic valuation. We also verified this framework through case analysis.

This research suggests feasible means for domestic railway industries to actively enter overseas railway markets by thoroughly analyzed the business trends of the expanding international railway markets and their characteristics. The 983 independent cases of international railway orders introduced in domestic markets during the past five years were analysed. In order to enhance the efficiency and consistency of the series of analysis, one classification system was established, and proportions of each category were assessed after the analysis of each piece of business information in the classification. It can be concluded from the analysis that early entrance into new projects with system design similar to that used in Korea will enrich the chances for domestic industries to enter the expanding international railway market, because Korean business is likely face competition from other companies for low-price contracts if the entering timing to the market is too late.
