Résumé / Abstract
Drivers' needs in safety functions must be defined from a human-centered point of view, going beyond technical offers. This paper presents a study conducted in the frame of the European TRACE1 project, focusing on the diagnosis of such needs from a detailed analysis of the real difficulties met by drivers in accident-generating situations. This study is based on a sample of 432 car drivers involved in a road accident. The sample was extracted from INRETS (France) in-depth accident studies database (EDA). The analysis relied upon a human error production model (Van Elslande, 2003; Van Elslande & Fouquet, 2007) delineating the different perceptive, cognitive and motor functional failures leading drivers to have an accident. Drivers' safety needs were deduced from these failures of the functions that usually make the driver able to compensate for driving system malfunctions. Drivers' difficulties in accident production show an important need in: 1) detecting other users, 2) diagnosing driver's condition, and 3) controlling the vehicle. Drivers needs in safety functions were defined from attested safety problems as they are expressed in accident. A complement of such an approach is to be found in naturalistic driving studies. The definition of needs relies upon an ultra in-depth analysis of accident cases with detailed interviews of people involved and cinematic reconstruction of the events.
