Overtaking and passing under adverse visibility conditions. Volume II: driver judgment and decision-making in accelerative passing situations on two-lane rural highways.

The overall goals of this research were to broaden the understanding of driver judgment and decision-making in accelerative passing situation and to study the effects of adverse visibility conditions on driver passing behaviour. The conceptual approach was to determine the ability of drivers to judge the speed and distance variables and to establish the actual relation between these variables and the passing decisions.
