Abstract:This exploratory field study investigated the weak resilience signals of workload in a rail traffic control room.The goals of this research are to see whether real-time system information of a rail control post can be used to predict workload of a rail signaller in real-time (Siegel & Schraagen, 2014) and to further improve this method. In order to investigate this question, three workload measures were used. The first was the subjective Integrated Workload Scale, the second was a physiological measurement of electrodermal activity and the third was behavioural observation. For three cases, the subjective workload was compared to the system information algorithm and the two other workload measures. The results show that the system information of communication, manual actions and switch cost are discriminating for workload. The system information about monitoring and planning did not seem to discriminate between different levels of workload. This study validates that system information can be used to predict workload. With this information insight in functioning of the rail signaller could be enhanced, which can improve the resilience of the rail post.
