An NTUA Diploma Thesis titled “Comparative analysis of road safety between EU and USA” was recently presented by Charie Tsoukalas. This Diploma Thesis revealed that that an increase in speed limit leads to an increase in lives lost in road crashes. At the same time, an increase in GDP per capita leads effectively to a decrease in fatal accidents and that all US States and EU countries were ranked in order of road safety effectiveness, demonstrating that countries of the EU countries have more effective (safer) road systems than those of the USA, possibly because of the higher vehilcle fleet and lower public transport modal share in the US. pdf5 ppt5
