As industry develop rapidly, a possibility of railway-disasters (fire), are growing in consideration of speedy railway and increasing long tunnels. In Korea, KTX consists $46\%$ of tunnels constructed since early 1990, prescribed prevention disasters standard, taking into account that the train accident occurred. On this provision which refers other country's a high-speed railway fire safety regulation and is synthetically reflected topographical circumstance and tunnel size in Korea, in order to minimizing valuable casuality and securing safety operation of train from rapid evacuation and rescue a passenger from accident in tunnel.

To establish the national railway safety system, the railway total safety technology development project has been promoted by Ministry of Construction and Transportation (MOCT) since August 2004. The project is mainly focused on the prevention of a critical railway accident and the reduction of accident/mortality rate. To achieve its goal effectively, the project is composed of 15 sub-projects each of which can be categorized into three different technological area. This work deals with the verification results for the outcomes of the sub-projects carried out at the 2nd year of the project. A new verification procedure is developed and applied to the project based on the system engineering. Three criterions - The suitability of the realization of a function, the suitability of a physical structure, the suitability of a design analysis report - are used for the verifications. The verification results are investigated by calculating standard deviations of scores of each results.

Railway System has been developed by applying the advanced technology so that it reduces accident of hardware failure. But human error has been founded as important cause in railway accidents and safety. Medical condition is one of railway accident causes. Failure to recognize potentially incapacitating medical conditions can have serious safety consequences for railroad employees, the railroads and the public[1]. In order to find potential danger, we collect domestic/ foreign case for the medical examination and analyse characteristic/difference. The purpose of this study is to suggest information of employees' medical examination through comparing the current medical standard in railway industries.

Passenger safety is a primary concern of railway system but, it has been urgent issue that dozens of people are killed every year when they are fallen from train platforms. In this paper, we propose a vision based monitoring system for railway station platform. The system immediately perceives dangerous factors of passengers on the platform by using image processing technology. To monitor almost entire length of the track line in the platform, we use several video cameras. Each camera conducts surveillance its own preset monitoring area whether human or dangerous object was fallen in the area. Moreover, to deal with the accident immediately, the system provides local station, central control room employees and train driver with the video information about the accident situation including alarm message. This paper introduces the system overview and detection process with experimental results. According to the results, we expect the proposed system will play a key role for establishing highly intelligent monitoring system in railway.

본 연구는 철도관제사의 인적오류를 유발하는 요인이 무엇인지를 AMOS 구조방정식 모형을 활용하여 탐색적으로 검증하려는 목적에서 시도되었다. 관제사와 관련된 문헌연구를 토대로 피로와 스트레스를 외생변인, 정보처리과정에서의 오류(인지, 기억, 저장 및 실행오류)를 내생변인, 그리고 종속변인으로 책임사고와 아차사고를 설정하였다. 여러 기관의 현직관제사 201명의 설문을 분석한 결과, '스트레스 ${\rightarrow}$ 기억오류 ${\rightarrow}$ 저장오류 ${\rightarrow}$ 아차사고 ${\rightarrow}$ 책임사고'의 인과관계 고리가 성립한다는 것을 발견하였다. 이 같은 연구결과는 인적오류와 관련하여 관제사의 사고 저감을 위해서는 그 선행요인인 스트레스를 효과적으로 관리하여 정보처리과정에서의 기억 및 실행오류를 저감시킬 필요가 있다는 것을 시사한다.

As the Public use part of the railway and the road, the railway crossing is important to work properly by two transportation means. Also, It is important to provide the good face of friction on the railway crossing in aspect of protecting the railway crossing accident. Lately, the material of railway crossing panel is the wood, the asphalt, and the steel. As they have a various fault, it was studied to analyze the structural action of the new material, rubber panel. This paper analyzed eigenvalue, stress and displacement by truck passing weight, thermal stress and train moving weight, using the FEM model.

There has been a significant decline in the number of rail accidents in Korea since system safety management activities were introduced. Nonetheless, analyzing and preventing human error-related accidents is still an important issue in railway industry. As a railway system is increasingly automated and intelligent, the mechanism and process of an accident occurrence are more and more complicated. It is now essential to consider a variety of factors and their intricate interactions in the analysis of rail accidents. However, it has proved that traditional accident models and methods based on a linear cause-effect relationship are inadequate to analyze and to assess accidents in complex systems such as railway systems. In order to supplement the limitations of traditional safety methods, recently some systemic safety models and methods have been developed. Of those, FRAM(Functional Resonance Analysis Method) has been recognized as one of the most useful methods for analyzing accidents in complex systems. It reflects the concepts of performance adjustment and performance variability in a system, which are fundamental to understanding the processes of an accident in complex systems. This study aims to apply FRAM to the analysis of a rail accident involving human errors, which occurred recently in South Korea. Through the application of FRAM, we found that it can be a useful alternative to traditional methods in the analysis and assessment of accidents in complex systems. In addition, it was also found that FRAM can help analysts understand the interactions between functional elements of a system in a systematic manner.

Korea's first tram (so called "tram"), which was commenced the operation on May 4, 1899 of late Joseon Dynasty and run until 1968, played a pivotal role of public transportation. However, tram as new transportation mean is being recognized as traffic congestion problem becomes issue due to geometric automobile increase and reckless urban plan after stoppage of tram service. Tram has an advantage of inexpensive construction cost and eco-friendly means compared to existing and city railway, carrying more passengers rather than existing bus, excellent connectivity of existing transportation because of easy accessible to destination in the city center. Therefore, tram, what is called "Green Rvolution of Public Transportation", has a dreaming of revival and in the process of pushing. We suggest the accident type which might break out in the early stage of tram introduction and preventive measures by surveying the accident cases of tram advanced country, and study the crossing control measures.

This paper examines the outcomes and tasks of U rail privatization especially focusing on the rail safety. Earlier research which focused on the rail safety had little knowledge of the explanations for recent changes of safety scheme. Moreover, they had difficulty making a direct comparison of safety between national rail and the privatized rail. Therefore we are left without a good explanation which has a comprehensive perspective. I attempt to show the outcomes of safety in the rail privatization process and its tasks focusing on the recent fatal accident. This paper argues that the UK's rail safety has a framework which is too complicated with overlapping responsibilities that brought about inefficiency, increasing costs. Especially infrastructure enterprise did not come to play an appropriate role. However, after 2000, the government took charge of setting the strategy for railway safety, and the Office of Rail Regulation covered safety, performance and cost. I explain that these changes present a good opportunity to solve the problem of passing the buck for rail accident. Through the analysis, I find that outcomes of rail privatization in safety are improved comparing the national rail. However, safety performance, for example the collision of structures of cars and looseness of rail should be improved. In future, the problems of fatal accident and a bit of duplicate safe system should be addressed.

THE DOMESTIC AND FOREIGN OF THE COUNTRY RAILROAD ACCIDENT ANALYSIS IT LED FROM THE PAPER WHICH IT SEES AND IT ANALYZED A TRAIN COLLISION/DERAILED ACCIDENT RISK FIXED QUANTITY. THE TRAIN ACCIDENT OCCURS DIRECT AND LATENT DAMAGE. IT CLASSIFIES THE ACCIDENT WHICH 5 YEAR FOR OCCURS RECENTLY DOMESTIC AND FOREIGN OF THE COUNTRY WITH A TYPE FROM THE RESEARCH WHICH IT SEES. IT TRIED TO ANALYZE THE DAMAGE SIZE AGAINST A TRAIN COLLISION/DERAILED ACCIDENT WITH DANGEROUS QUOTIENT.
