Driver's Working Memory and Stress Response Analysis Under Typical Accident Types
To examine the relationship between different working memory patterns in the accidents,drivers'stress response ability and visual behavior,this study carried out driving simulator experiments on 31 drivers under three typical accident types of side collision,rear-end collision and scraping pedestrians on urban roads.Based on the output video of the camera and eye tracker,dynamic clustering was used to divide the driver's gaze area into 7 categories.Meanwhile,the stress response ability and visual behavior of people with different accident types and different working memory capacities were analyzed based on one-way Analysis of variance(ANOVA),Mann-Whitney U test and Kruskal-Wallis test.The results show that there is a significant correlation between the accident type and the driver's stress response ability.The driver's reaction time in the emergency braking event of the front vehicle is the shortest,which is reduced by 25.46%compared with the side collision.Reaction time in the face of danger is affected by the driver's working memory capacity,that is,the driver with a high working memory capacity has a shorter reaction time than the driver with a low working memory capacity.In addition,the total duration of fixation,mean saccade time and pupil diameter were correlated with working memory capacity.The research results can provide theoretical support for targeted early warning of vehicle safety.
