Abstract: A fundamental ethical and practical problem facing road safety professionals around the world is that in order to analyze safety and identify hazardous locations, an excess number of collisions, usually requiring a long observation period, need to be observed which safety engineers will subsequently strive to prevent. As well, collision data suffers from considerable quality and quantity issues and the data does not offer a complete understanding of the collision mechanism and how safety treatments work. This presentation describes novel automated road safety analysis techniques developed at UBC which are based on advanced video analysis technology which offer a solution that can change how traffic safety is managed by enabling the detection of collision risk without the need for collisions to occur. Furthermore, this approach should offer a better understanding of collision failure mechanisms, particularly the collision-avoidance behaviour of road users which should help our diagnosis of the safety problems and the selection of safety countermeasures. With all recognized limitations to the state-of-practice, many safety practitioners believe that within this research lies the future of road safety analysis. Case studies from projects in several countries worldwide for various safety applications are presented.
