Effects of Sleep Quality and Hazard Type on Simulated Driving Performance of Young Novice Drivers
Objective This study investigated the effects of sleep quality and hazard type on the driving perform-ance of young novice drivers.Methods mixed experimental design of 2(sleep quality:insufficient sleep,adequate sleep)x and 2(hazard type:active hazard,passive hazard)was used to finish the simulated driving task of 26 drivers with insufficient sleep and 26 drivers with adequate sleep.Results Drivers perform worse in the face of positive haz-ard,with higher average speeds,smaller lane offsets,higher steering wheel corners and lower headway.The sleep-in-sufficient group has more dangerous driving performance than the sleep-adequate group,with more lane offsets and lower headway.However,in active hazard,sleep-insufficient drivers show smaller lane offsets and higher headway.Conclusion Active hazards lead to more dangerous driving tendencies(speeding)in drivers,and that sleep-insuffi-cient drivers respond to passive hazards worse than sleep-adequate drivers.
