This paper was presented at session 35 - drivers, vehicles and geometrics 2. Further development of a 'paper and pencil' analogue of intersection and overtaking decision problems suggested by a human factors evaluation of the Melbourne intersection control program (metcon) has resulted in a 'driver decision questionnaire' that incorporates control sequence, en route traffic, centreline marking, and security of the road ahead as well as number to be overtaken, immediate control environment, and threat from the side roads in its design. A trial administration of this questionnaire has shown significant discrimination of cognitive responses on all of these dimensions except centreline marking. Effective differentiation of anticipatory response dispositions, or cognitive stereotypes, with implications for ability to adapt to changes in the control environment also was demonstrated. It is argued that continued development and validation of this technique is warranted. The number of the covering abstract of the conference is IRRD no. 239340.
