A Diploma Thesis titled “Greek drivers’ attitudes towards aggressive driving” was recently presented by Aggeliki Stefatou. The objective of this Diploma Thesis is the investigation of the characteristics of driver aggressiveness in Greece via their perceptions on their own behavior and the behavior of other drivers. Specifically, within the framework of the SafeCulture survey, the answers of 302 car drivers and 201 two-wheeler drivers on 8 questions regarding speed, 6 questions regarding overtaking behavior and aggressiveness and 4 questions regarding alcohol consumption were analyzed. Results indicate that drivers do not perceive traditional crash factors as causes for their crash involvement. The only contributing factors perceived by drivers was found to be those involving driver overtaking behavior and aggressiveness. pdf5 ppt5
