Abstract:

Safety is defined by the interactions and relationships between road-users, vehicles and the infrastructure. But what is it that determines whether a situation is critical or unsafe? Due to the many disadvantages of analyzing accident statistics, safety is often defined as its ‘output measures’, or proximal or behavioral safety indicators. Examples are speed, speed variability, time headway, SDLP, TLC and TTC. But where do we draw the line, what are good cut-off values for these behavioral indicators? In order to come up with international standards, more research is needed to fill in knowledge gaps. This article provides an overview of the link between behavioral indicators and traffic safety. It also discusses earlier attempts and new possibilities for setting cut-off values. The central research question in a new TNO project is how to link behavioral indicators to what can be qualified as safe or unsafe. This paper is a call to join forces and combine the existing data of naturalistic driving studies and field experiments with new research. There is a need to combine behavioral indicators into one risk factor, and add the link with behavior in specific surroundings. Cut-off values can be the end result of a large research proposal, combining data from alcohol studies, visual distraction data and driver drowsiness studies.
