The investigation described in this report has been directed toward the identification and description of the behavioural rules applied by traffic participants in a priority situation. Behaviour was observed by video registration on two locations, one having a special priority regulation (with signs and pavement markings), the other without specific regulation (so that the general regime of priority-to-the right applied). The interest in the registration was in auto-auto and auto-bicycle encounters, where one of the participants would approach on the minor road and the other on the major road of the location. Head movements of those involved in encounters were also observed, and these were used as a gross indicator of where attention was directed during an approach. The study led to the following conclusions: (1) the special priority regulation led to outcomes of encounters-in terms of who went first -that were more often formally correct than for the general rule, (2) auto-auto encounters more often lead to a formally correct outcome than auto-bicyle encounters, (3) the outcome of an encounter is also determined by the initial configuration, i.e., which partner had the initial advantage in terms of time to get to the intersection, (4) an interaction exists between the priority rule prevailing, the type of encounter, and the initial configuration, (5) motorists approaching over the minor road follow a pattern of head movement activity that only depends on the prevailing priority rule, (6) participants in an encounter approaching over the major road devote more attention (in terms of head movement activity) to partners on the minor road when these are formally entitled to have priority.
