Résumé / Abstract
Decision making is one of the major processes involved in drivers' cognitive activity; generally this is seen as a more or less conscious trade off between the objective and subjective risk of a situation. Our approach concerns the effect of time pressure when drivers must decide in ambiguous situations, and more specifically the way they notice relevant information. Twenty-eight subjects completed a route in a real driving situation where they had to cope with confusing traffic intersections. Our first results show relationships between the experience of the scene and driver behaviour in crossing the intersections. This also gave us the opportunity to identify some elements for classification of each scene as a function scene complexity. These results will be used to formulate additional hypotheses which will be tested in an experiment carried in a driving simulator.
