Abstract

Foreign object encroachment is the presence of persons or items in the contact network and railroad track area, which can result in accidents, electrical failures, and train damage on the railroad. By keeping an eye on the lookout, seeing the intrusion of a foreign object, and braking quickly, train drivers can lessen the risks brought on by foreign object invasion. The question of how to maintain and monitor the continuous attention level of train drivers has been a hot issue, because of the monotonous environment of railroad operating makes the alertness decline during threat perception. Based on the theory of situational awareness, this study posits that training drivers in foreign object encroachment experience schemas can enhance their sustained attention levels, leading to improved hazard perception sensitivity. The hypothesis is subsequently verified in different route types and road types. We utilized a set of 24 videos depicting railroad traffic scenarios, generated by a driving simulator, to examine the sustained attention levels and hazard perception capabilities of train drivers. The participants in our study were divided into two groups: one group consisted of train drivers with recent experience of foreign object intrusion (n = 37), and the other group comprised train drivers without such recent experience (n = 35). The study's findings suggest that schemas have an impact on hazard sensitivity by influencing the extent of sustained attention. This effect is further moderated by the pseudoneglect effect and prioritization of task goals. The results provide confirmation that the situational awareness theory holds valuable insights for enhancing the training of train drivers in hazard perception and sustaining attention. And it also addresses a previously existing gap in the literature regarding the factors affecting train drivers' hazard perception. These findings can be instrumental in shaping training programs aimed at safety awareness, as well as the design and implementation of alertness monitoring systems for train drivers.
