A Diploma Thesis titled “Spatial analysis of driver safety behavior using data from smartphones” was recently presented by Ilias Parmaksizoglou. Smartphone driver behaviour data were processed in a GIS computer environment, resulting to the development of new tables describing the phenomena observed on the map of a major road axis in Athens, in nodes and links. Analytic maps were developed aiming to indicate patterns of the accumulation and ranking of the harsh events in the selected road axis. Finally, four linear regression models were developed, which demonstrated speed as the most statistically significant factor in predicting harsh events per day on a region basispdf5 ppt5
