| Abstract |
With the development of modern science and technology, the railway sector has also become more automated and advanced in systems, resulting in higher train speeds and mass transportation of passengers. While the probability of accidents has decreased compared to the past, the severity of damage is greatly increasing. With the recent enforcement of the Serious Accident Punishment Act, only one worker can be killed. If an accident caused by human error occurs as an industrial or civil disaster, it will cause great personal and social repercussions, so countermeasures are needed. According to the results of analysis of accidents and failures over the past five years after the integration of the Seoul Metro Rapid Corporation, the highest number of accidents caused by human error occurred in the crew sector (65.3 %), and human errors such as careless handling and negligent verification occurred during repetitive work performance. It appears
that it is doing so. Urban railway crew members board and drive moving trains, stopping at each station every 2 minutes and 30 seconds and performing repetitive tasks handling an unspecified number of passengers. Due to the nature of the work, human errors mostly occur during the work process. Work process risk management is necessary. This study is based on the human error analysis (HEA) technique and is a railway crew work process risk assessment measurement tool to identify the degree of accident risk due to human errors such as careless handling and neglect of confirmation for each task during the work process performance of railway crew members. It is a study on development. |
