Effect of Forward Collision Warning Systems on information processing: An electrophysiological study

Résumé

Rear-end collisions represent approximately 30% of all car crashes and has a large economic impact on society. Driver inattention has been identified as the most important contributing factor in rear-end collisions. In this context, Forward Collision Warning Systems (FCWS) have been developed specifically to warn drivers of potential collisions. The main objective of this work is to evaluate the impact of a surrogate FCWS according to its reliability and the attentional state of the driver. Participants were required to avoid collisions with a lead motorcycle in a simplified simulator across three different conditions: driving with a perfect FCWS, with an imperfect FCWS or without a FCWS. In half of the scenarios they simultaneously performed a secondary cognitive task (i.e. dual task). Driving performance measures were recorded along with electrophysiological measures. Results at behavioural level found 1) slower drivers’ reaction times when in a dual-task condition; and 2) a benefit of the FCWS in the primary task (i.e. driving). Electrophysiological results revealed 1) a disruption of the target processing by the secondary task at sensory and at higher cognitive neural levels; and 2) a compensatory effect of the alert in dual task. In conclusion, these data shed new light on how an alert can affect the processing of the visual scene.
