Understanding individual on-road behavior has been a key issue in traffic safety research. A deeper insight into the driving patterns has been so far restricted, due to limited availability of actual longitudinal data and exposure data. This paper presents an innovative approach in which actual driving data obtained by means of an in-vehicle data recorder (IVDR), are used to evaluate its safety implications. In particular, this paper analyses two major issues regarding the validity of such systems as safety promoters. The first is the correlation between the safety grade given by the IVDR system and the driver's history in collision involvement. Once this correlation is established, the second issue is the ability of drivers to change their behavior in the desired direction, namely to become safer drivers. The results obtained, based on 71 drivers, 7500 trips and more than 3500 hours driven, indicate that: (1) IVDRs' driver classification and safety scores are significantly correlated with collision history. (2) High impact on collision reduction once drivers are exposed to their data (over 50% reduction of collision rate). (3) Behavioral change is maintained for the duration of the experiment (so far – 7 months and continuing) (4) Significant reduction in speed events.
