A Diploma Thesis titled “Relation of the performance of road safety to medical, economic and social indicators to countries in the European Union” was presented by Myrto Damianou in July 2018. The purpose of this diploma thesis is to identify potential relationships between road accidents and road behavior, as far as the health sector is concerned. Its aim is to relate the performance of road safety to medical, economic and social indicators related to countries in the European Union. Thus, the 27 European Union Member States are studied for an indicative time frame, from 2008 to 2014. After determining the correlation between road fatalities and the aforementioned indicators, the statistical models were defined, according to the application of the theory of linear regression and the linear mixed model. pdf5 ppt5
