The scope of this diploma thesis is to investigate the benefits of eco-driving in urban roads and highways. For this purpose, an experiment was conducted in a driving simulator, and 39 young people participated to collect road data. Additionally in order to gather their stated characteristics, a questionnaire was distributed during the experiment. At first, participants had to drive as usually, and after an eco-driving briefing, they drove ecological. The results were analyzed using statistical models. Linear regression models were deployed, as well as binomial logistic regression models. The developed statistical models were related to carbon dioxide emission, carbon monoxide emission, nitrogen oxide emission and the accident probability. It was shown that eco-driving contributes to reducing the emission of carbon dioxide, carbon monoxide, nitrogen oxide and the probability of the driver being involved in an accident. Finally, it was observed that of the two types of roads examined, the emission of pollutants reduced in urban environment compared to highways, in contrast to the possibility of an accident, which is higher.
