Abstract
This paper presents a pilot experimental study carried out by
the Laboratory of Accidentology and Biomechanics PSA Peugeot
Citroën - RENAULT (LAB) and the European Center of Safety Studies
and Risk Analysis (CEESAR) on the RENAULT ESTER motionless driving
simulator. Sixty-eight drivers were exposed to a dangerous
situation in which another car failed to stop at an intersection.
Three distinct configurations were tested: vehicle coming from the
right either at a constant speed or decelerating, or stationary
vehicle moving-off from the left. Kinematic data and a video
presenting the driver''s face and the field of view were
recorded. After the driving session, drivers were interviewed by a
psychologist of in-depth accident investigation teams in order to
analyze their interpretation of the situation.
The analysis carried out is based on a comparison of the
behavior (perceptions, interpretations, actions) of drivers who
avoided the accident with the behavior of those who crashed. It
points out different kinds of difficulties according to the
configuration: problems of perception (angular limitations),
anticipation (no anticipation of the possible motion of the adverse
vehicle) or interpretation (incorrect estimation of the danger
level). It provides a basis for the determination of avoidance
strategies and the design of active crash avoidance systems
(intelligent collision avoidance systems as well as active braking
boosters) with the specification (triggering threshold) and
efficiency assessment of such systems. This study also provides
data for accident reconstruction (e.g., reaction time in accident
situations, motion perception threshold...).
