Effects of Different Emotional Music on Driving Fatigue and Arousal Experiment

Abstract

With the rapid growth of the number of motor vehicles, road traffic accidents are becoming more and more serious. Fatigue driving has become one of the main causes of traffic accidents. It is particularly critical to find effective solutions to fatigue driving. At present, the academic community believes that the phenomenon of fatigue driving can be controlled by means of prevention and intervention. In terms of intervention countermeasures, using sound stimulation as a wake-up method has the advantages of easy implementation and significant effect, which has become the research focus in the driving fatigue mitigation scheme. Through the establishment of a simulation driving platform, driving fatigue detection system and driving fatigue wake-up system in the laboratory, the experimental research is carried out to study the fatigue generation of drivers in different emotional types of music environment and the effectiveness of wake-up countermeasures. Three sound environments were constructed in the experiment, which were driving noise environment, positive emotional music mixed with driving noise environment and negative emotional music mixed with driving noise environment. The subjects were tested in three sound environments in turn. When entering fatigue, they were given no stimulation, positive emotional music stimulation or negative emotional music stimulation according to the experimental design. The experimental results were obtained after considering the subjective evaluation questionnaire and the experimental data analysis based on pupil diameter variation coefficient, average blink rate and other indicators. The experimental results show that when driving for a long time, the driver will enter the fatigue state regardless of whether the driving background has different emotional music. The driver's fatigue depth in the positive emotional music environment is shallower than that in the negative emotional music environment and the music-free environment; there is no significant difference in the degree of fatigue between the driver 's fatigue in the negative emotional music environment and the fatigue in the absence of music environment. In the comparison of music arousal stimuli with different emotions, the introduction of positive emotional music as arousal stimulus has the best effect.
