Pertinence of the behavioural activities in the assessment of the attention at the wheel versus neurophysiological parameters (résumé)

Résumé / Abstract
During long journey on motorways the driver-s impairment detection would be of great importance to avoid numerous fatal crashes. The aim of several research laboratories and cars manufacturers is to detect low vigilance at the wheel: the choice of combined parameters seems to be necessary to characterise the state of the driver. The objective is to continuously monitor the driver attention. Without to modify the attention capacities, at least during the research phasis: this is 3 very classical problem in psychology to observe the behaviour without influence of the observation methods on this behaviour. The paper shall briefly describe several categories of the assessment methods of the driver's attention and begin by the sleepiness scales and their high sensitivity, in actual driving situation and in simulator, before and after the work. The behavioural activities in the car, body, head and members movements could help to establish the degree of fatigue. Alone or associated to classical psychometric tests, like reaction time. Characteristics of driving behaviour, assessed through dynamical car's parameters are changing when the process of falling asleep at the wheel is beginning. The validity of these categories of methods is discussed at the light of association with eeg, slow eye movements (eye rollings), blinks, in order to propose a set of combined parameters which probably has the better efficiency to detect low vigilance.
