According to Railway Safety Act, Korea Transportation Safety Authority (KOTSA) has been entrusted with 'Integrated Railway Safety Audit (IRSA) and has implemented the safety audit to the Railway operation agencies such as Korea Railway (KORAIL) and the Railway facility management organization such as the Korea Rail Network Authority (KR Network). The target of IRSA is to establish the effective rail safety management system and to raise the safety level of the Railway operation and facility agencies by checking synthetically their performance of safety duties with sincerity according to the Railway Safety Act. Even though newly introduced IRSA is conducted smoothly, it is necessary to study the methodology and criteria of the state's safety audit system. The purpose of this paper is to improve the efficiency of IRSA by the comparative research between IRSA and other similar safety audit system and to establish the consecutive improvement concept of IRSA. Second purpose is to confirm the effectiveness of IRSA by the analysis of the relationship between audit results and the safety level of the rail operation agencies.

The railway crossing is very dangerous because the track intersects with the road there. Thus, The laws were designed for safety of the railway crossing and they are classified as to the acts for the road and the railroad. For safety of the railway crossing, there are 'Road/Railroad Crossing Improvement Promotion Act', 'Enforcement Decree of Road/Railroad Crossing Improvement Promotion Act', 'Rules on Construction of Railroad', 'Rules on Safety Standards of Railroad Installations', and 'Enforcement Ordinance of Cable way/Railway Track Act' in the acts for the railroad and there are 'Road Traffic Act', 'Enforcement Ordinance of The Road Traffic Act', 'Ruled on Structure and Facility Standards of The Road', 'Rules on Structure And Facility Standards Of The Rural Road' and 'Rules on Structure and Facility Standards of The Installations for Bicycle' in the acts for the road. Both the acts for the road and the railroad have standards for the structure of the railway crossing. However, they have different standards. Besides, they don't have standards for new facilities which were recently installed for safety of the railway crossing. Therefore, we suggest new standards for safety of the railway crossing.

Infrastructure such as tracks, catenary, rolling stock and signaling systems, and close interface with the human factors of train drivers, shunting staff and maintenance staff are required for train operations. Safety management is the most essential part for the functioning of a train. In line with the safety management, each rail operator has a safety guidance system and the Ministry of Land, Infrastructure and Transport operates Railway Safety Inspector system. Safety Inspector System is to train employees working in the field to be aware of rules and regulations, and to improve identified risk factors. Hence, it is necessary to establish systematic training and inspection methods for safety guidance staff and make clear the roles and responsibilities of safety inspectors according to the Occupational Safety and Health Act, and safety instructors for several inspections according to the Railroad Safety Act.

Risk-based railway safety management has been mandatory in Korea as by relevant laws and regulations enacted since the Railway Safety Act 2004. In particular, the Railway Vehicle Safety Guidance came into effect on Jan 1, 2008 specifies the details of methodology for hazard analysis, risk assessment and safety verification and validation. Fundamentals for success of the risk-based safety management are systematic hazard identification and risk assessment by use of reasonable risk assessment criteria, but the principle of risk-based safety management has not been applied in an effective way to introduction and maintenance of railway vehicle systems because definite risk assessment criteria have not been set down for each railway system or railway network. The purpose of this study is to suggest a risk matrix development principle for risk assessment of domestic urban metro vehicles by analyses of relevant rules and railway operating environment of Korea.

In order to establish railway long-tenn safety policy, various railway safety indexes are required. But these indexes are not use efficiently due to the limitation of safety information. Recently m any safety related information have been obtained based on Railway Safety Act 2004. In this study, various safety index, which can be applied both preventive safety activities and safety measure development, are proposed. These safety indexes are based on common safety index in European Railway Agency, but also include special index in Korea. Proposed safety index include accident results, precursors to accident, infrastructure, accident cost and safety management system. These indexes will be applied in railway industry from 2009.

According to the Railroad Safety Act and section 42 of the Enforcement Ordinance, railway operators should conduct railway safety training regularly(6 or 3 hours per three months). But Overall Railroad Safety Audit conducted 2006 pointed out nonfulfillment of a regulations on railway worker's safety training to each of every 4 railway operators, which proved that the training management had not carried out properly. E-learning is used in various fields with development of Internet and IT technologies. It might be a good alternative tool for railway workers who is in shift working of the company 24 hours a day. Because it is difficult to collect those employees for training, e-learning could overcome obstacles of time and distance. In order to find out suitable e-learning model to railway sector, e-learning system for railway safety training has been researched through investigating e-learning technology and present railway safety training condition.

The railway safety in Koreaisthreatenedduetotherestructuring of the railway industries, introduction of the Korea Train eXpress (KTX) and electrification of the conventional lines. Many technical backgrounds are required to control railway accidents as low as reasonably practicable, such as a railway safety act, safety standards, and safety assessment infrastructures. Korean government and the Korea Railroad Research Institute (KRRI) are conducting an integrated R&D program for improvement of the railway safety, where the target is to reduce the accident fatalities by half. The program is composed of three parts; the safety system engineering and the program management, the establishment of a safety management system, and the development of techniques for assessing and preventing major railway accidents. Details of the research programs are explained in this paper, where risk is used as the major control measure.

Recently the assurance of railroad safety is very important issue in KOREA because there are lots of changes in the railroad industries. The Railway Safety Act was established in order to cope with these changes effectively and prevent the railroad transportation accidents. According to this law, Korea Transportation Safety Authority (KOTSA) has been entrusted with 'Integrated Railroad Safety Audit (IRSA)' and has implemented the safety audit to the railroad operation agencies such as Korea Railroad (KORAIL) and the railroad facility management organization such as the Korea Rail Network Authority (KR Network). The target of IRSA is to establish the effective rail safety management system and to raise the safety level of the railroad operation and facility agencies by checking synthetically their performance of safety duties with sincerity according to the Railway Safety Act. The purpose of this paper is to improve the efficiency of IRSA by the comparative research between IRSA and other similar safety audit system. To study the efficiency of IRSA, we investigated the rail safety audit systems of EU system specially France, England where the big changes have happened for the rail operation concepts and Japan where government entity control the railroad safety. The international standards of Occupational Health & Safety Assessment Series (OHSAS 18001), Quality Management System (ISO 9001) and Guidelines for Quality and/or Environmental Management Systems Auditing (ISO 19011) are investigated.

Around two years have passed since the beginning of aptitude test required by 2006 Rail Safety Act. At this point, it is necessary to evaluate the validity of the aptitude test. Through this study, the structural system for all the tests would be overviewed, which will show the correlation among each tests or its importance. Also, although it is rough, reliability and validity of the tests would be overviewed by their retest and education materials. This would contribute, in the future, to setting up for the standard of upgrading or integrating the tests.
