This paper suggests to reclassify railroad accident types and to standardize them as the standardized code for the railroad safety management system. The existing railroad accident types in both domestic and foreign cases have been carefully analyzed in the beginning. Based on the case studies, the new railroad accident types are classified into 9 classes which are not overlapped one another and 9 classes have been subdivided into 40 different accident patterns. All these patterns are linked with 9 different accident objects and 6 accident locations. Therefore, this study suggested the combination of 4 distinct code factors: accident class, accident pattern, accident object, and accident location to standardize them. In addition, inter-operation between the proposed codes and the existing accident types is suggested. This code will play a major role in the railroad safety management system composed of accident prevention, accident preparedness, accident response, and accident recovery.

This paper suggests to standardize railway accident restoration types as the code and standard operation system for efficient railway accident management. First of all, the damage types of have been carefully analyzed and reclassified. This study suggested the combination of 3 distinct code factors: restoration class, restoration object, and restoration location to standardize them. In addition, this study suggested procedures to make the standard operation system of emergency restoration, defined the worst case of emergency restoration and the important events. Therefore, the standard operation system of emergency restoration is developed. It shall play a major role as the database system for railway accident management, minimum of damage and rapid control of accident.

The paper suggests to reclassify the casuality accidents types and causes at urban rail stations in the standardized code manner. In order to make standardized codes, 4,086 casuality accidents for Seoul Metro and Seoul Metropolitan Rapid Transit Cooperation (SMRT) are analysed. The standardized code for casuality accident types includes 4 distinct factors; casuality object, casuality location and casuality pattern. Also, the standardized code for casuality accident causes includes 4 distinct factors: casuality trigger, drinking or not, first cause and second cause. This code is deemed to play a big role to link the same casuality accident types or causes which can be used in the process of railroad safety management and emergency response system.

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.

We have identified which causes have influenced to accidents, case by case through a relational analysis on data of accidental case, root case, accident cause and hazard. The data on the accident of railway operation and system have been analyzed and the root cause, accident cause and hazard have been classified. This research has developed accident cause analysis system to build efficient railway safety policy which will be used to prevent railway accidents by government and railway operator.

The theory of risk is applied frequently in analysis of railway accidents. The aim of risk analysis is to search potential causes and contribution factors of accidents by checking the total system of construction field. This paper analyze a pattern and a cause of accident occupied in construction field, calculate risk index considering accident frequency and severity, and then provide the relative risk assessment. Based on this, this paper will provide the methodology of qualitative risk assessment guiding to reach a consistency of risk index with risk assessment.

Most railroad accidents are due to human errors. In particular, most of the causes of these accidents are faults of an engine driver, such as lack of signal confirmation, insecure braking, driving by guess or force of habit. This paper identifies a problem(s) by analyzing accidents for the past 10 years and also seeks a solution to train good engine drivers in order to prevent railroad accidents. In summary, what is needed are: 1) proper placement of various manpower, 2) proper training of engine drivers, 3) proper legislation for a 2-man on board system, and 4) proper reformation of personnel management.

Negligent accidents in urban railway station not only give damages to users but also cause avoidance of public transport usage. This study aims to identify design factors in designing urban railway station for reducing and preventing negligent accidents in the station. Especially this study identifies design factors from the perspectives of universal design concept which is for all persons. This study classified negligent accidents in urban railway stations, analysed degree of danger and identified the causes of accidents. Then this study identified universal design factors based on the results of analysis on the priority of accident factors relating to negligent accidents. The results of this study can be utilized as basic data in designing urban railway station for reducing and preventing negligent accident in urban railway station.
