Résumé / Abstract
Driving a car is often more a difficult activity than usually thought, relying on perceptive, cognitive and operational skills acquired through practice. These driver's regulating functions are sometimes over requested and their adaptation capacities pushed to their limits. Road accidents are the most evident symptoms of this capacity exceeding in compensating for driving demands. Nearly each accident goes through a Human Functional Failure (HFF), i.e. a failure in one or another function (from perception to action) that usually enable road users to compensate for the difficulties they diarly meet at the wheel. Intelligent Transport Systems are one of the means potentially able at helping car drivers to carry out their driving task more safely. But in order to be appropriately defined, drivers' needs in safety functions must be characterized from a human-centered point of view, going beyond technical offers, and considering the real difficulties met by drivers in the purpose of conteracting HFF. Moreover, the parameters characterizing the contexts of accident production are also to be taken into account as the constaints to integrate order to fulfill these needs efficiently. This paper presents a study conducted in the frame of TRACE (Traffic Accident Causation in Europe) European project, focusing on the diagnosis of such needs and constraints from a detailed analysis of accident-generating situations.
