Individual Differences of Driver Distraction Characteristics during Real Driving
To explore the individual differences in visual distraction characteristics when drivers perform secondary tasks,a real-car experimental platform was constructed,and visual distraction data were collected from 30 participants.Four indicators,including total duration of visual distraction,number of visual distractions,average duration of a single visual distraction,and maximum duration of a single visual distraction,were selected for characteristic analysis of the collected data.The spectral clustering algorithm was employed to cluster drivers'distraction styles into cautious,normal,and aggressive types.The results indicate that increased complexity of secondary tasks significantly increases total duration,number of visual distractions,and maximum duration of a single visual distraction.Increased vehicle speed significantly decreases total duration of visual distraction,average duration of a single visual distraction,and maximum duration of a single visual distraction,with the impact on total duration of visual distraction and average duration of a single visual distraction becoming more pronounced with increased task complexity.Significant differences are found in visual distraction characteristics among the three distraction styles of drivers,with cautious and aggressive drivers tending towards multiple short-duration and fewer long-duration operation modes,respectively,during secondary task execution.
