A Method for Evaluation System of Railway Driver Non-Technical Skills Construction

Abstract

The frequency of adverse events in rail traffic control system has been linked to the quality of teamwork and communication. With the automation developed, non-technical skills (NTS) underpin technical ability of railway drivers and are critical to the success of operations and the safety in the railway system. Developing suitable NTS evaluation system of railway drivers may play a role in reducing human errors in railway. In this study, four important NTS were selected to describe behaviors of railway driver in automation conditions: situation awareness, decision-making, communication and self-management. Consultation with experts and task analysis led to modifications reflecting the complexities of the railway drivers, particularly the coexistence of three post (driver, dispatcher and integrated controller). The scale was then developed using questionnaire and principle component analysis (PCA) method, and structural equation model (SEM) used to assess the reliability and validity of the NTS scale. The model can provide a certain basis for the evaluation, selection and training for railway drivers, enhance the NTS and ensure the safety of railway system.
