  • As a result of investment in railway safety since 2004, railway accidents have been reduced by half and we reached a high level of safety compared to other countries. But people are still worries about railway accident, and want safer railway. It is difficult to determine which level of safety must be achieved due to lack of comparative studies on railway safety among different countries and other transportation modes. In this study, a comparative study on railway accident statistics and various transportation modes is performed. The results of this research can be used for the determination of weak areas of railway safety and the level of safety to be achieved.

  • Since the opening of Seoul Subway Line #1 in 1974, the number of passengers has been increasing. The possibility for passenger's accidents in railway stations has also increased. In order to decrease these kind of accidents, railway operation systems have been automated. Nevertheless, the possibility of a casualty accident in railway stations remains. This study analyzed the type of casualty accidents, casualty accidents by age, sex, pedestrian facility, and passenger type based on the internal data of Seoul Metro. The causes of casualty accidents are also found out. Finally, the establishment of railway safety education program and railway safety experience center are suggested in order to prevent the urban railway casualty accident in advance at railway stations.

  • The government of South Korea has made great efforts in the area of railway safety management by means of a railway safety law and an integrated railway safety plan established in 2004 after the Daegu subway fire accident. However, after certain railway incidents, a reactive railway safety management system has been implemented that has led to fatal accidents caused by the collision, derailment, and fire every year. Hence, this study is intended to propose a framework that integrates data from distributed detection devices into a real-time railway safety monitoring and control system for proactive safety management. Furthermore, we will provide a future development direction for safety performance monitoring indicators to determine whether the railway safety monitoring and control system works effectively. The proposed framework is expected to be a cornerstone for the real-time railway safety monitoring and control system to be implemented in the future.

  • 철도안전법의 제정 및 시행에 즈음하여 철도안전관리에 대한 인식이 제고되고 있는 시점에서 인적요소를 고려한 전기철도안전관리기법을 제시한다. 이를 위해서는 인적신뢰성분석이 필요하나 현재로서는 세계적으로도 이에 관한 규격이 정비되어 가고 있는 실정으로서 국내에서는 규격 적합성 인증 제도가 아직 구축되어 있지 못하고 따라서 규격 정비의 진행에 따라 위험성정보교환에 관련된 대책의 필요성이 증가하고 안전성의 확률론적 정량적평가가 보다 중요시 될 것으로 예상된다. 본고에서는 시스템 위험도분석을 통한 안전공학적 절차를 준수함으로써 위험도를 정량적으로 평가하고 정량적으로 평가된 위험도를 적정 수준으로 관리함으로써 철도시스템 안전관리체계를 향상시킬 수 있는 기법으로서 최근 주목받고 있는 인적신뢰성분석기법과 위험도정보교환에 대한 기본 개념을 제시한다.

  • According to the national railway safety plan 1 billion US$ have been invested in railway industry every year. As a result, railway accident rate has been reduce to half recent 6 years. Currently, Korea has 3 kinds of national railway safety target, which are accident fatalities, train accident rate, and passenger fatality per passenger kilometer. Increase of railway passengers and train operating companies force to set up new safety target. Current safety target cannot reflect train operator's safety activities because they include suicide and trespass related accidents, which are hard to be controlled by the operators. In order to reflect to the national railway safety plan, new safety targets are proposed in this study.

  • In this paper, we review the regulations relating to railway safety and station workers interviewed, eight urban rail accidents decreased operating agencies through the prevention research currently being conducted into the (Seoul Metropolitan Rapid Transit Corporation City, Seoul Metro, Incheon traffic mortality, etc.) the root cause for the lack of aggressive prevention measures performed on the difficulties related regulations, organizational culture and work environment, prevention of negative operating authority derived in three improvements were obtained through this direction. First proposed urban railway safety ever buy Conduct production, utilization and operating agencies college safety assistant suggests directions for safety training, organizational culture and work environment improvements in senior management. Finally, active accident prevention campaigns, and provide direction to increase the educational participation of guests. Improvement for such accidents would decrease is thought to play a role in the prevention of future operating agency established when the guidelines.

  • This study propose a model for railway safety evaluation with which the safety of whole railway system can be evaluated. The evaluation model is to generate a safety index which quantitatively represent the degree of railway safety. Safety index is proposed a function of three indexes; an accident index, safety management index, and safety culture index. This paper describes the first result from the study on the safety target which will be a key starting point toward the development of safety evaluation model. It is recommended that the safety target be composed of several sub-targets that are apportioned to constituent components. It is coneluded that the classification of safety target influence on deciding components or attributes that constitute each sub-indexes; an accident index, safety management index, and safety culture index.

  • Using transportations like railway, aviations and roads have been increasing continuously. Traffic accidents have been increasing as well. To prevent or lessen these accidents become a big issue to solve. Therefore, more enforced safety levels are being required to meet. In railway field, continuous efforts of railway safety are being executed to prevent traffic accidents. In present, railway accidents have been decreasing since subway accident happened in Daegu Subway in 2003. However, safety levels in railway field have not yet achieved as much as in advanced countries. Basic concept for enforced safety level in railway system is to prevent or minimize accidents by managing systems like related facilities, management method, organization, education. This is the same concept to minimize error rate in six sigma theory. In this paper, we are to apply six sigma techniques used in manufacturing industry to railway safety and go through ways to make more efficient railway safety system.

  • The paper suggests risk management methodology for alleviating casuality accidents at urban railway stations. Risk management deals with countermeasures for reducing accident probability or consequences to reach at the certain level of risk. First of all, Economic evaluations using cost and benefit for all the alternatives are performed. The alternatives exceeding B/C ratio greater than 1, each alternative is applied in the order of higher B/C ratio. this process is repeated when the level of risk is reduced as low as reasonably practical (ALARP). In order to determine the level of ALARP, Level of Service (LOS) for casuality risk at urban railway stations is proposed. The ALARP level is set to the LOS "C". Finally, a case study is applied to the Jongno 3-ga station, which is a highest risky station among all the stations operated by Seoul Metro and Seoul Metropolitan Rapid Transit Cooperation (SMRT).
