This Diploma Thesis aims to investigate the impact of weather conditions on young drivers’ behavior and safety in urban areas. In order to achieve this objective, an experimental process on a driving simulator was carried out, in which all participants drove in different driving scenarios. Regression statistical models were developed to investigate the impact of weather conditions on the mean speed, the lateral position of the vehicle from the right borderline (lognormal) and the accident probability (logistic). The models’ application shows that driving in the rain contributes to a small reduction in speed, but also to a significant increase in the probability of an accident. When driving in fog, drivers seem to be more cautious, as the lateral position of the vehicle from the right borderlines reduced and the probability of an accident decreased.
