  • Studied was a strategy of technology development for railway system in terms of railway network. First, The successful launch of the Korean HST system has not only decreased logistics burden but also significantly transformed the Korean trunk-line railway network, revolutionizing the logistics and technology sectors and reinvigorating the Korean railway industry in one century. Korean railway industry sector is now investing to develop many different types of railway system(G7, Post G7, tilting train...) so that these kinds of various railway system development should be integrated with the National Inter-modal Transportation Network Plan. To secure sufficient capacity that is required by the National Railroad Plan, the railway industry needs to establish mid- and long-term train purchase and operation strategies in compliance with railway construction and operation policies. During a railway construction planning, train operators, based on their train operation strategies, should come up with measures to closely cooperate with project operators from the planning stage through to the opening of a railway system. To be more precise, train operators should establish long-term train procurement plans reflecting both long-term national railroad network plans and plans for each railway line in order to suggest appropriate roles and schedules for each line. Also, based on the long-term railway plan, directions should be decided concerning the research and development of trains in advance.

  • Recently with the rapid development in mobile communication, the mobile phone are utilized in many fields of railway system within country and abroad and its use tends to increase continuously. In the railway system, the applicable realm is spreaded to the fields of railway signal communication, railway operating, track maintenance, reservation and information service, also its role is expected to increase. In this thesis, we are surveying the usage application of home and abroad mobile phone in railway system. Studying the present condition of mobile communication in railway system, we are viewing the application plan and the direction of development.

  • Recently, fundamental innovation for the improvement of Korean railway industry is proceeding with the vertical separation into infrastructure and operation, and the privatization of railway operation. And also, with the advent of an era of high-speed railway, starting of Korea Train Express (KTX) will give a great change to circumstances of railway industry. It requires that a railway safety regulation policy and accident survey system cope effectively with this restructuring of railway system. Under these great changes, safety must have the first priority, and the function of management and supervision on railway safety will be ten to the governments responsibility; In this paper, according to changes of railway safety management system, foreign states railway accident system and direction of korea railroad accident survey system will be also introduced.

  • A Structure of a system is usually described as same as an architecture, but they are basically different. The architecture has a broader meaning than a system structure. In other words, an architecture can include many of system structures. So, to define the architecture, we need to consider how functions of a system are consisted and integrated. The architecture defined is applicable to railway safety management systems, and it can be made as a new model for railway safety systems, which is useful to systematize railway safety regulations. To establish the architecture as applicable to railway safety regulations, it is required to compare between regulation relations by analyzing roles before/after executing railway safety regulations. Therefore, in this research, we reviewed and classified different types of regulation conditions and safety requirements for railway systems and a variety of conditions before/after railway safety regulations changes are compared by defining system architectures subject to National railway safety.

  • Safety is important factor in railway system. Now most of the electric and electronic system which is applied in railway system is the embedded system which software is used. The constitution rate of software which is involved in railway system is gradually increasing. Most of the software which is used in railway system is implemented by the software developer. Thus the implemented code has different features according to the developer and this may cause the bad effect on the software's maintenance. International standard IEC 62279 requires an adoption the coding standard to developing the railway software. And it is plan to recommend complying with the coding standard in safety criteria for railway software which is noticed as the regulation of the Korean railway safety law. In this paper, we review the requirement of coding standards which is present in the software criteria for railway software and international standard. Also it investigates the coding standard which is in other safety related industry and presents the effective way to apply the software coding standard to domestic railway industry.

  • In this paper, we propose a pilot study to deploy the Railway Conflict Detection and Resolution System(RCDRS) in the context of Korean Railway(KORAIL). KORAIL plans to deploy in near future RCDRS, which is a decision support module placed on the top level of the Railway Traffic Management System(RTMS). This study entails the review of the state-of-art researches and projects in the field of the railway traffic management, as well as the analysis of the traffic characteristics of the major railroad lines in KORAIL. The analysis provides a basis to choose a solution approach for the railway conflict detection and resolution problem that each individual line faces. This study plays a role as a pilot study for a full systematic approach, in which interactions between lines require further advanced analysis to take the entire KORAIL lines into consideration rather than a myopic approach.
