A Diploma Thesis titled ‘Macroscopic analysis of road accidents at junctions’  was presented by Konstantinos Kapetanakis in November 2011. Processed data were used, extracted from the database of the Department of Transportation Planning and Engineering of the National Technical University of Athens (N.T.U.A.) for the time period 1996 – 2007 in Greece. Analysis has led to a series of conclusions such as that the more usual accident type in junction is the collision at angle and that regardless of the area type, the accidents which occur out of junctions are at least double than those which occur at junctions.
