Effects
Driver Behaviour Patterns
reflexive head nod after checking the side mirrors
less frequent of head motions
times of touching chin, face, head, ears, eyes, and legs increased
turn their head to the left to relieve muscular tension in the neck
Eye-blinking activity radically increased
frequent of yawning
more relaxed hand positions on the steering wheel
Other Physiological Responses
Low frequency EEG
Driving Performance
lower frequency of steering reversals
a deterioration of steering
decrease in the steering-wheel reversing rate
no steering correction for a prolonged period of time
low-velocity steering
large amplitude steering-wheel movements
large standard deviations in the steering-wheel angle
