THE FINNISH TRAFFIC CONFLICT TECHNIQUE .INTERNATIONAL CALIBRATION STUDY OF TRAFFIC CONFLICTS. PROCEEDINGS OF THE NATO ADVANCED RESEARCH WORKSHOP

According to the Finnish method, situations where braking or weaving begins 1.5 second or less before a potential collision are defined to be conflicts in urban traffic conditions, where the speed limit is 50 km/h. The time-to-collision value that defines conflicts varies with the speed limit or level at the study location. Also potential conflict situations are recorded in the Finnish method. Conflict observations are made by 2-4 persons. Video equipment is always used in order to check observations and to gather exposure and behaviour data. The method has been used in short-term evaluation of safety measures and safety analyses of junctions. The studies have been commissioned by Finnish towns, the Ministry of Transportation and the roads and waterways administration.(a) for the covering abstract of the conference see IRRD 279243.
