Study On The Characteristics Of Driver Fatigue Of Male And Female Drivers

Driving fatigue refers to a decline in response level after a period of driving.This decline is manifested in distraction and severe drowsiness,resulting in driving failure or driving failure.A survey found that the death rate of road traffic accidents caused by drowsiness is 50% higher than that of other types of road traffic accidents.The literature of this system has not been found in China.This study explores the measurement of driving fatigue and the difference in driving fatigue between male and female drivers through experiments.Previous studies on driving fatigue mostly focused on driving fatigue and driving fatigue.However,there were few studies about gender differences in driver fatigue.Moreover,the measurement of driving fatigue mostly uses some traditional measuring instruments,such as EEG,heart rate,eye movement and so on.Although these instruments can measure drivers' driving fatigue in the laboratory environment,it is unrealistic to put them into a wide range of use.Therefore,the study on driving fatigue as the core,through the driver's eye blinking frequency and GSR value to verify the existence of driver fatigue point;and on this basis,and further driver fatigue and their differences in conversion of unknown and known task difference.In this paper,we use the driving simulator,physiological polymeter,eye and face detection system and other experimental instruments.The following three experiments are done based on man and number.In Experiment 1,the driver's driving fatigue was measured by physiological multidetector and eye face detection system,and the existence of fatigue point during driving was verified.It is proved that skin power can be used as a new index for driving fatigue measurement.On the basis of Experiment 1,experiment 2 further explored the difference of fatigue changes between male and female drivers during the continuous driving process.Experiment 3 takes Chinese characters and numbers as materials,and uses task transformation paradigm to study the differences between male and female drivers in predicting driving tasks and unknown tasks.From the above experiments,we can draw the following conclusions:(1)there are fatigue points in the driving process,and fatigue point is 74 minutes or so when the driver is driving continuously,that is,when the driver's subjective fatigue is 4.(2)there is a significant turning point in the relationship between blink frequency and fatigue level.This turning point is the driver's fatigue point,while the skin power value decreases with the increase of driving time.(3)male driver's anti fatigue ability is stronger than the female driver,the female driver's fatigue state with the driving time and increases slowly;male drivers may remain for a long excited state in the driving process,but when they feel tired,fatigue will be sharp and strong.(4)the ability to drive stress is actually a kind of ability to perform the task of conversion under unknown conditions.
