As technologies are developed and systems are complicated, hazards embedded in the system are also increasing. proving safety and managing the safetyis more scientific and organizational domain so that safety management system is pursuing to be activeformation detecting the factors of hazard and managing them beyond passiveway. In the future, in order to establish and manage national safety management system, it is important to have effective system and manage it and also more important that all the people related to target system has to change their recognition and to playroles in it. Many railway safety measures reduce railway fatalities into half for last 10 years. But more improvement in railway safety is required to meet the social need after railway fire accident in Daegue. After the Daegue subway train fire accident, the Korean government has been trying to prepare a nation-wide railway safety program, a safety organization, and a Safety Act. To construct a nation-wide railway safety management program, system architecture was established.

Railway signal system is responsible for the safety operation of railway and performs vital functions as safe space control, route control and etc. These functions prevent collision accidents between trains and derailment accidents of trains. However, these accidents are occurred by some causes. It is necessary to analysis hazards, hazard frequency and risk contribution. And railway signal system must make practical application of the analysis results. This paper includes analysis results of railway accident data by FTA(Fault Tree Analysis) and hazards. Railway signal system must consider these hazards. This paper used the railway accident data of RSSB(Railway Safety & Standard Board) of UK. We will use the FTA result to set up a draft of safety criteria of railway signal system.

안전관리를 위해 정량화된 데이터를 바탕으로 통계기법을 통해 분석, 해석, 관리하는 기법은 제조업에서 수행하고 있는 6시그마 혁신운동과 거의 유사한 절차를 통해 수행되므로 철도안전관리에 있어서도 이러한 기법을 도입 하여 정량화된 관리기법이 도입되어야 한다. 본 연구에서는 경영혁신운동인 6시그마와 철도안전관리의 차이점에도 불구하고 제조업에서 성공적으로 활용하고 있는 6시그마 기법들을 철도안전에 적용할 수 있는 방안을 모색함으로써 일부 안전관리 과정에서 해결하지 못하거나 많은 어려움이 존재하고 있는 부분에 대한 해결책을 찾아 효율적이고 체계적인 철도안전관리에 일조하고자 한다.

It is important to safety culture in railway industry because they variously refer to the safety-related values, attitudes, beliefs, risk perceptions and behaviours of railway employees. So this study tried to figure out the assessment criteria for safety culture at Korean National Railway. For the achieve the goal, we have the literature review, some assessment criteria have been founded by intensively comparing safety culture questionnaires in other industries to establish domestic railway safety. This study expects Korean railways to become a well-organized that as assessing safety culture with reasonable criteria or requirements.

According to the computerization of railway signalling systems, the safety demonstration and assessment of railway signalling system is very important. For this reason, railway signalling systems reflect the needs of methodology to assessment the safety. Then many studies of safety assessment methodology for railway signalling systems centering on the Europe, have been made continuously, and the requirements for safety acceptance are currently standardized by IEC. To develop and establish the safety assessment technology for railway signalling system in Korea, we are reviews the safety assessment activities for signalling system through the reviews of related std., case study and consulting by experts.

System safety management to secure complicated system safety such as railway and nuclear includes various factors. Those are prevention of accidents, faults management, human factor, men-machine relation, organization factor, safety culture, quality/quantity safety performance goal, and safety regulations. To manage them, it is required that database which is based on most analysis is established. Therefore system safety could be controlled. This research defines data required to safety management, and that is aimed at deriving plans in order to establish them as database. To accomplish that, safety information management of other systems such as aviation and marine is reviewed. Also, the present conditions of available data in the filed of domestic railway are analysed, and then it provides plans for. establishing database to build up advanced railway system safety information management systems.

Purpose - This thesis is to develop a management plan and checklist by analyzing the prevention of accidents in advance by presenting the management plan for the major causes of railway accidents. Research design, data and methodology - In recent 5 years, we have analyzed the cases of railway accident, presented the management plan for the accident, and made a practical safety checklist focusing on the main measures according to the management plan. Results - The analysis of the cases of near-railway accidents suggests more concrete and practical safety management measures because the similar accidents are continuously occurring due to formal safety management. Conclusions - It is more valuable to apply to the adjacent construction of the railway line by creating a detailed checklist based on cases rather than the existing checklist. This study is written only as a human factor. For future real - time safety management, it is necessary to study more precisely cause analysis and safety equipment as a big data - based safety control system for more systematic safety management.

A systematic methodology to determine safety requirements for railway signalling system and safety requirement allocation into system are presented. THR concept is used for as an interface between Risk Analysis to be performed by railway operator and System Design Analysis by the supplier. This approach is based on Signalling Safety Standard EN50129 by CENELEC.

Railway safety management information systems are now being developed by various railway related organizations. A large number of railway safety related data were gathered from railway operators, railway infrastructure manager and railway intendance, etc. The meaning of these data can easily be defined by each organization or developer with little regard for reusing of data by others. Until the present, the main efforts for data management focused on classifying the railway safety data by subject for the developer's convenience and how to combine these data each other is not interested in. In this study, data integration is considered from the viewpoint of combining them semantically in order to get more useful information from partially informed data of multi agencies.

As far as recent investment in railway, disused railway yards is increased in each line and region. As a result, the interest of the related local government and agencies has increased on utilizing disused railway yards. In this study, we investigated the status of the disused railway yards and conducted legal review on the use of disused railway yards. In addition, we analyzed the disused railway yards use practices through case analysis and also suggested plans to diversify the ways of their usage.
