Physiological and Behavioral Changes of Passive Fatigue on Drivers during On-Road Driving

Driver fatigue can be further categorized into passive and active based on the task-induced perspective, with its categorization necessary from a theoretical basis practical needs. Passive is caused by mental underload inactive task engagement, which considered more hazardous. To facilitate construction of driver monitoring system (DMS), current study aims to investigate physiological behavioral changes fatigue. A total thirty-six participants completed 90 min driving monotonous highway, during subjective level, eye tracking indicators, dynamics were recorded using Stanford Sleepiness Scale, Smart Eye Pro, CAN Bus system. Results showed that drivers reported higher levels as duration increased. An increase in pupil diameters gaze dispersions observed task. Drivers gradually reduced control vehicle, faster speed lower compliance witnessed. In addition, compensatory process was found tended their standards maintain lateral position but recovered when they lost car speed. The emphasizes importance investigating independently, unique accompanied should designing systems.
