INTENSIVE OBSERVATIONS VIA VIDEO RECORDING AND ANALYSIS WERE MADE OF DRIVER BEHAVIOUR ON SEGMENTS OF MAIN ROADS ON RADIAL VERSUS CROSS-TOWN AXES OF THE ROAD GRID IN AN INNER MELBOURNE SUBURB. THE ROADS SELECTED WERE SCHEDULED FOR TRANSITION TO FULL PRIORITY STATUS IN THE VICTORIAN GOVERNMENT'S PRIORITY ROAD PROGRAMME (METCON). THEIR STATUS DURING THE PRE-METCON PERIOD CONCERNED WAS THAT OF MIXED PRIORITY ROADS WITH ISOLATED CONTROLLED INTERSECTIONS. A PROFILE OF DRIVER BEHAVIOUR BASED ON OBSERVED PATTERNS OF CONFLICT RESOLUTION AND OVERTAKING EVENTS WAS CONSTRUCTED THAT WILL ALLOW COMPARISON WITH A SIMILAR PROFILE OBTAINED DURING A POST-METCON PERIOD. THIS PROFILE IS ALSO COMPARED WITH A COGNITIVE RESPONSE PROFILE DERIVED FROM A QUESTIONNAIRE SURVEY WITH RESPECT TO SYSTEM PARAMETERS SUCH AS INTERSECTION PRIORITY ALLOCATIONS AND MEASURES OF SYSTEM CONFIDENCE. THE OUTCOME OF THIS COMPARISON SUGGESTS THAT THE DRIVING POPULATION WAS ALREADY AWARE OF THE APPLICABLE PRINCIPLE OF PRIORITY ALLOCATION, ALTHOUGH IMPERFECTLY, AND SOMEWHAT INCONSISTENT IN BEHAVIOUR WHEN ASSESSED BY INDICES OF SYSTEM COMPLIANCE AND CONFIDENCE.
