Introduction speech and closing remarks at the preparatory ICTCT-Meeting for the Joint International Calibration Study of Traffic Conflict Techniques 1983, Copenhagen, 25-27 May 1983.

The lack of traffic safety is regarded as the whole of existing and potential critical combinations of circumstance, incidents (conflicts) and accidents in traffic and the individual and social consequences (damages) caused by them. A model for the accident process was developed and discussed here in relationship with the conflict technique.
