Effects Of Personality And Music Preference On Driver's Risk Perception

Traffic accidents are closely related to driver's risk perception.Driver's ow n characteristics and situational characteristics will have an impact on driving b ehavior.In today's increasingly popular car music culture,the impact of music on driver's risk perception can not be ignored.Previous studies have not select ed drivers' preferred music.This paper explores drivers' risk perception based o n drivers' preferred mainstream music and personality characteristics.Study 1 u sed questionnaire survey to investigate drivers' preference for listening to music in their cars,and to explore the relationship between personality,music prefer ence and risk perception.Study 2 used reaction time measurement and Study 3used eye movement measurement to systematically explore the mechanism of music preference on drivers' risk perception from the aspects of risk identificati on,reaction speed and visual search mode.Research results: In the first study,it was found that driver's risk perception skills score of self-assessment had g ender differences;rigor,agreeableness,openness and extroversion were positivel y correlated with driver's risk perception skills score,while neuroticism was ne gatively correlated with driver's risk perception skills score;regression analysis found that the main effects of driver's driving age,gender,rigor,openness and extroversion could explain 37.4% variation of driver's risk perception.The sec ond study found that the braking times in obvious dangerous situations were gr eater than those in potential dangerous situations,and the reaction time was lo nger and the difference was significant.The third study found that the pupil di ameter of pop music was larger than that of light music;the first gaze time o f light music was longer than that of pop music;the number of gaze times of pop music was higher than that of light music,and the difference was signifi cant.No interaction between music preference type and risk type was found.C onclusion: There is a certain relationship between personality and driver's risk perception skills.Drivers with different personalities have different advantages a nd disadvantages in identifying dangerous information.Although music preferen ce types have no effect on driver's reaction time and braking times,eye move ment results show that pop music arouses better.The dangerous types of traffic situations have a greater impact on driver's risk perception.The ability of dri vers to identify potential dangerous information is poor.
