Study on the Subjective and Objective State of Young Students Facing Traffic Accident Videos
The occurrence of road traffic accidents is usually unpredictable and accompanied by sudden characteristics.The state of drivers in this process is of a significant impact on traffic safety.In this paper,young students are taken as the research object.According to four different types of traffic accident scene videos,the characteristics of EEG signals are analyzed by time-frequency analysis and frequency domain analysis methods,and the subjects'subjective feelings are evaluated by using Likert 5 scale.Quantitative analysis and modeling were carried out based on the subjects'personal information and EEG changes in each rhythm in the questionnaire.The results showed that young males showed greater psychological fitness and emotional stability relative to females.Young students were less prone to anger but generally anxious about the occurrence of accidents.Driving mileage was significant for both θ and β waves.In the face of rear end collision and pedestrian scratching accidents,θ wave changes in the prefrontal region of the brain were more obvious,and θ wave can be used as an evaluation index for safe driving.
