A Diploma Thesis titled ‘Comparative multilevel road safety analysis in European capitals‘ was presented by Marianthi Mermygka in May 2014. Data on the number and the characteristics of road fatalities, the population and other indicators of the nine selected European capital cities for the period 2007 – 2011 were exploited. Multilevel Poisson statistical models were developed, allowing for a clearer hierarchical data structure and the road safety performance ranking in these cities. Factors found with a statistically significant impact concerned city characteristics (road network length, population density, public transport use) and accident characteristics (road user and vehicle type). The comparison between the European capital cities showed that the larger the city’s road network is, the higher the level of road safety is in this city.
