運転技能の自己評価がリスクテイキングに及ぼす影響

抄録

Traffic psychology researchers have discussed the relation between the self-assessment of driving skills and risk-taking behaviour.　From previous work, it can be hypothesized that drivers who overestimate their　roadcraft take more risks.　In this study, two investigations were carried out.　First, respondents (N = 201) were required to rate their own driving skills and report the extent to which they drive safely.　In addition, we conducted a naturalistic observation at a T-shaped intersection to compare the risk-taking measures and the self-estimate of driving skills (N = 36).　The questionnaire study demonstrated that drivers with three to five years of experience after acquiring their licences overestimated their driving skill and reported not to drive very safely.　The observation revealed that high-confidence about driving skills accounted for the tendency not to pay much attention to either side of the road and to make tight right turns.　The results suggest that accurate self-evaluation of one's own driving skill is necessary for preventing risk-taking behaviour and driving offences.
