The technical research centre of Finland has for many years used the traffic conflict method in evaluating the effects of traffic safety measures and devices. Effectively trained observers and video equipment are used at the field studies. In addition to conflicts also potential conflict situations, traffic violations and traffic flows are registered at the study locations. Following are some safety measures, the effects of which were studied with the traffic conflict method: (1) refuges on pedestrian crossings, (2) characteristics (signal control, refuges, location at junction or between junctions) of pedestrian crossings across a 20 m wide street, (3) acceleration lanes at grade-separated junctions, (4) the replacement of crawling lanes with overtaking lanes. A conflict simulation model for junctions has also been developed.(a) for the covering abstract of the conference see IRRD abstract no 264967.
