Abstract:
Vigilance decrement has become one of the main risk factors for train accidents. lt is of great signifi-.cance to evaluate high-speed train drivers' vigilance in real time during long-duration driving. In thisstudy, a driving simulation experiment was conducted to collect multimodal physiological informationand the vigilance index was defined by principal component analysis (PCA) to identify its evolution.Furthermore, the effects of sound and vibration stimuli on arousing vigilance were analyzed, and visualcharacteristics during vigilance decrements were examined. The results indicate a significant vigilancedecrease after 30 min of driving, more pronounced at 45 and 65 min. During vigilance decrementsfixation points decrease, vision narrows and key visual information is more likely to be ignored. Bothvibration and sound stimuli arouse vigilance, with vibration acting more rapidly while sound increasesgradually. These findings provide a theoretical basis for real-time monitoring vigilance and ensuringdriving safety.
