A Study Of The Effect Of Driving Experience And Personality On Driver's Risk Perception

Based on analyzing of traffic accident, we know that, most traffic accidents were analyzed that some drivers are lack of risk perception, they can't find traffic risk, especially in novice drivers. Therefore, we selected some novice and experienced drivers as subjects, in order to study the effect of driving experience and personality on driver's risk perception, included obvious risk perception and potential risk perception.By the cognition and assessment of the risky pictures, it could reflect driver's risk perception. We showed two groups of traffic pictures by the computer, one were obvious risky pictures, the other were risky pictures. By using the technology of eye movements, we tracked record drivers eye movements data when they were looking at the pictures, furthermore, we also had driver's assessments on the pictures. The experiment consists of two experiments which are all 2(driving experience :experienced and novice )×2(personality: field independent and field dependent) between-subjects designs. Experiment 1 was to find the effect of driving experience and personality on driver's obvious risk perception. Experiment 2 was to find the effect of driving experience and personality on driver's potential risk perception.The results are as follows:(1) when looking at the obvious risky pictures, field independent drivers had longer Total Fixation Duration,Pupil Diameter and Number of Fixations than field dependent drivers.(2) when looking at the potential risky pictures, experienced drivers had longer Total Fixation Duration,Pupil Diameter,Number of Fixations and Number of Gaze Points than novice drivers ; field independent drivers had longer Total Fixation Duration,Pupil Diameter,Number of Fixations and Number of Gaze Points than Field dependent drivers ; field independent novice drivers had longer Total Fixation Duration,Pupil Diameter,Number of Fixations than Field dependent drivers.From the analysis of the results , the conclusion were :(1) driving experience didn't influence on driver's obvious risk perception.(2)driving experience influenced on driver's potential risk perception, experienced driver had higher potential risk perception than novice drivers.(3) personality influenced on driver's obvious risk perception, field independent drivers had higher obvious perception than field dependent drivers.(4) personality influenced on driver's potential risk perception, field independent drivers had higher potential risk perception than field dependent drivers.(5)field independent novice drivers had higher potential risk perception than field dependent novice drivers.
