A Diploma Thesis titled ‘Time series analysis of basic road safety parameters in selected groups of European Countries’   was presented by Anastasia Pnevmatikou in July 2004. For this analysis a detailed database was developed containing disaggregate road accident data from 15 EU Member States, while another data base was developed containing aggregate accident data for the 25 EU Member States for the period 1991-2001. The results lead to the conclusion that the increased traffic participation of two-wheel motor vehicles and pedestrians in southern countries of Europe as well as the passenger car motorization increases in the east countries, have a negative impact on road safety level of these countries.
