This Diploma Thesis aims to correlate driver’s characteristics with its safety performance. In order to achieve this objective, two sets of assessments were
used where 12 drivers participated on an expert assessment using on-road driving together with a self-evaluation questionnaire. The analysis of the drivers’ behaviour was carried out using the statistical methods of factor analysis and linear regression analysis. Three groups that characterise drivers’ perception of careless, aggressive and cautious driving behavior were derived from factor analysis. Moreover, linear regression analysis revealed that driving experience, headways, self-reported driving skill and defensive driving positively affect the overall on-road driving performance score. More precisely, it was ascertained that driving experience leads to statistically significant increase in overall on-road driving performance score.
