Quantification of Safe Driving

Assessing driving safety calls for the quantification of driving performance in relationship to safety. While traffic safety can be evaluated by measuring the number of fatalities, injuries and crashes in traffic, this is only possible after these crashes have happened. The challenge in measuring driving safety is to relate driving behaviour as measured to the likelihood of crashes occurring. This not only concerns the driving behaviour of one single driver and vehicle, but also the interactions of this driver with other road users. Consequently, not only driving behaviour but also traffic interactions need to be quantified and related to safety. In this report we provide a summary of the state of the art in qualitative and quantitative methods to reason about the safety of driving.
