An NTUA Diploma Thesis titled “Road Safety Benchmarking in Greek Regions” was recently presented by Kostas Michailoglou. Data of road accidents and the main characteristics of each Region were used for the period 2010-2019 and two linear regression models were developed for all Regions of Greece, with and without Attica. THe models results indicate that the number deaths per 100.000 population depends on the income per inhabitant and the number of vehicles, the number of physicians (with Attica) and the density of each district (km²/inhabitant) and the unemployment (without Attica). Subsequently, Data Envelopment Analysis (DEA) was used for the benchmarking of the 12 Regions (except of Attica) based on their performance on road safety. According to this classification, Thessaly, Ionian islands and Central Macedonia appear to have the best road safety performances, while Peloponnese and South Aegean have the worst ones.
