A Diploma Thesis titled “Combined impact of road and traffic characteristics on driver behavior using data from smartphones” was recently presented by Virginia Petraki. High resolution driving behavior data were collected through the OSeven smartphone application which were combined with traffic and road geometry characteristics and subsequently were depicted spatially using GIS. From the application of these models it is observed that in road segments there is an increase in the number of harsh events if average traffic volume per lane increases in the respective segments. Furthermore, in junctions as the average occupancy increases, there is an increase in harsh accelerations, and as average speed increases more harsh decelerations occur.
