Joint International Study for the Calibration of Traffic Conflict Techniques

Abstract

Traffic unsafety can be regarded as the whole of existing and potential critical combinations of circumstances, incidents (conflicts) and accidents in traffic and the individual and social consequences (damages) caused by them. The main feature of incidents and accidents is that they are always preceded by a critical combination of circumstances in traffic. Such critical combination of circumstances for example in a situation can be described as a situation wherein, with unchanged traffic behaviour and/or unchanged traffic situation, the interaction between man, vehicle, road traffic and environment leads to accidents (see Figure 1).
