Safety is an essential requirement for public transportation, especially for railway. Railway are more safety than other means of transportation, but railway accident that is mass transportation result catastrophic result if an accident occurred. Railway operators and government are many prior efforts to prevent accident, but it is impossible to eliminate accidents. Therefore, various measures to reduce accidents as possible, and they have taken, this paper will review incident report system and safety culture which are most important factors for preventing accident. In addition, incident reporting system and an independent accident investigation and accident prevention and safety systems would be needed to improve train operating companies and related agencies for the safety of the railway is a cultural ritual. Indeed, the settlement of avalid railway safety culture will most certainly prevent railway accidents. Therefore, in the railway company and the correct understanding of railway safety culture and against the settlement plan would be reviewed in this paper.

The newly updated Rail Safety Act is required to build a comprehensive railway safety management system with corresponding accreditation regulations for the purpose of safe railway operations. However, such efforts would not be enough to achieve a successful safety-performance solely without being in place of an appropriate level of safety cultures in an organization. No research was taken place to propose a safety culture maturity model and its estimate procedures in Korean railway industries. The research reviews a variety of safety maturity models applied in many other industries and the process of conducting surveys in order to propose a framework of railway safety maturity estimates, with a set of railway safety elements. This research is expected to contribute in diagnosing weak areas and finding their appropriate treatment, along with in placing the railway safety certificate program from 2014.

The study of safety culture estimate has received a wide attentions in many other industries, rather in the contexture of railroad stands at an initial phase. A factor analysis and internal reliability test were conducted to check if the survey results are reliable by looking at how the factors are dimensioned and how the questionnaires are sub-grouped in accordance with such factors, and further if there are any other common attributes being extracted as a new factor. The designed 5 factors were expanded to 7 through the test, and they were renamed accordingly. The questionnaires are reorganized according to the new 7 factors. It implicates that thorough investigation of the common attributes is important in reducing the gaps between interviewers' and interviewees' understanding. Moreover, the results of internal reliability test represent the new design of questionnaire is reasonably acceptable with the high reliable values. We expect such approaches can be applied for the railway culture survey study to be more reliable and applicable.

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.

Railroad construction requires a lot of budget, manpower, and equipment, and as a result, many accidents occur. Although efforts are being made at the national level to reduce the accidents at railway construction sites, the occupational accident rate is not showing a downward trend. Various efforts are needed to reduce accidents, the application of smart construction safety technology will be effective. However, if smart construction safety technology is introduced indiscriminately without analysis, duplicate investment may occur, which may lead to a waste of budget for railway construction. In this regard, this study analyzes accident cases at railroad construction sites through a survey of stakeholders and proposes smart construction safety technologies to be effective for those accident types.

This study analyzed the relationship between major parameters and numerical analysis results according to various excavations conducted around the urban railway, application of machine learning techniques and verified the scope of influence of the adjacent excavation on the existing urban railway box structure and the appropriateness of the safety area. This study targeted the actual negotiated adjacent excavation works and box structures around the urban railway, and the analysis was conducted on the most representative two-line box structures. The analysis confirmed that the difference in depth of urban railway, excavation depth of adjacent excavation, and depth of underground water level are important parameters, and the difference in excavation depth of adjacent excavation is the parameter that affects the behavior of underground box structures and is an important requirement for setting safety areas. In particular, the deeper the depth of the adjacent excavation work, the greater the effect on the deflection of the underground box structure, and the horizontal separation distance, one of the important requirements for determining the management grade of the existing adjacent excavation work, is relatively small.

The three-dimensional precision numerical analysis was performed using the finite element model applied with the railway track model consisting of rails, sleepers, and track elastic springs(ballast, rail pad). As a result of analyzing the track deformation level of the existing tracks due to the excavation work adjacent to the railway facilities, it was found that the track irregularity evaluation criteria (allowed values) of both conventional and high-speed railways lines were satisfied. Based on the numerical analysis using the track model, it was analyzed that the results of the prediction of the track irregularity due to the excavation work and the level of the track deformation occurring at the actual site could be approximated as closely as possible.

In case of damaged timber sleepers, maintenance is carried out according to the track inspection standard. However, it is difficult to detect the extent of damage on the bridge, and maintenance is depended on inspector's judgment. In this study, we propose to improve the evaluation criterion of timber sleepers for the ballast-less tracks on serviced urban railway bridge. The timber sleepers on railway bridge was classified according to degree of damage, and damage scores were calculated for each damage grade. Also we have improved the maintenance system of the timber sleepers through the history management system of the individual timber sleepers on railway bridge. As a results, it was judged that systematic management of timber sleepers could be possible during maintenance.

The purpose of this study is to investigate the cause of rail corrugation and the track force for concrete track (STEDEF) in the urban transit. From the field measurements, the dynamic wheel load, vertical displacement of sleeper and rail bending stress were measured and it was evaluated by regarding to the rail corrugation. As a result of the study, the causes of rail corrugation was experimentally proved by frequency analysis using measured dynamic wheel load data. The influence of corrugation on dynamic wheel load, rail bending stress and sleeper displacement was evaluated that the periodic irregularities of rail corrugation on the rail surface amplified the dynamic track force such as the dynamic wheel load, and thus the rail bending stress and the vertical displacement of sleeper could be increased by a maximum of 1.7 times.
