Correlations among self-reported driving characteristics and simulated driving performance measures

摘要

Following a driving simulator experiment investigating anticipatory competence in driving, participantswere asked to rate themselves on driving characteristics that are potentially relevant to anticipatorycompetence. Significant correlations were found among multiple of these characteristics. Furthermore, allparticipants also completed the Manchester Driving Behaviour Questionnaire (DBQ), so that correlationsbetween these subjective driving characteristics and DBQ categories could also be investigated. Findingsshowed that both subjective measures were generally aligned in that the DBQ categories correlated with thesubjective characteristics describing them. However, no evidence could be found that participants judgingthemselves as safe drivers kept longer headways and larger times to collision, and no significantcorrelations were observed between subjective ratings of fuel-efficiency and fuel-consumption observed inthe simulated drive. These findings suggest that caution should be taken when using self-reported drivingcharacteristics to predict actual performance, and future research should further investigate the relationbetween self-reported measures and simulator performance measures.
