Study On Influence Of Music On Recovery From Brain Fatigue Of Prairie Highway Drivers

With the rapid economic development and the increase of travel demand in Inner Mongolia,the density of prairie highway network increases gradually.Due to the single landscape ring and special road alignment of Prairie highway the formation and deepening process of fatigue of drivers on Prairie highway is different from that on other roads.If fatigue cannot be alleviated and eliminated in time,it will directly affect the driving ability of drivers and it will directly affect the driving ability of the driver,thus causing traffic accidents.Music adjustment,as a new means of fatigue recovery,is widely used by scholars in the field of sports fatigue recovery.As a fatigue recovery method,it can have a positive impact on people's psychology and physiology.In this study,the listen music was introduced as a fatigue recovery method to alleviate the fatigue of drivers on prairie highway.Taking EEG signals as evaluation indexes,through the prairie highway driving simulation experiment,the EEG signals of drivers under the condition of music adjustment and natural recovery during different degrees of fatigue recovery were collected.Analyzed the influence of music on the driver EEG signals.The research results provide theoretical support for enriching the driving fatigue recovery means and the driving fatigue recovery time of grassland highway.The specific conclusions are as follows:(1)In the recovery period of mild fatigue,the degree of fatigue of drivers is low.Both natural recovery and music adjustment can effectively eliminate the state of brain fatigue of drivers.The recovery time of music adjustment is 4?6 minutes,and the natural recovery time is 8?10 minutes.There was no significant difference between the two methods in the recovery time.(2)In the recovery period of moderate fatigue,drivers' fatigue level was deepened,music can adjust quickly eliminate the drivers' brain fatigue state,natural recovery will take a long time to recover their brain can effectively relieve fatigue,including music adjust the recovery time is 8?10 minutes,natural recovery time of 20?22 minutes.Music regulation was significantly ahead of natural recovery in terms of time,and there was a significant difference in the recovery effect between the two methods in the whole recovery period.(3)In the recovery period of severe fatigue,the driver's fatigue degree is seriously deepened.In the natural recovery group,drivers' ? wave and ? wave power values reached the stasis level after 26 minutes,but their own power values of 0 waves did not reach the stasis level,indicating that the natural recovery method had no obvious effect on brain fatigue recovery.The brain fatigue state of drivers in the music regulation group showed a trend from declining to rising,indicating that the music regulation time should not be too long,and the effect was the best around 10?12 minutes.(4)According to the increasing trend of the power values of,??? and 0 waves in drivers' EEG signals in different fatigue recovery periods,it can be seen that the indexes in the early fatigue recovery period of the music adjustment group changed significantly,indicating that the instantaneous recovery effect of music adjustment in the fatigue recovery period was the best.
