Résumé / Abstract
A Forward Collision Warning (FCW) could avoid a large number of rear-end collisions by informing distracted drivers of the danger. However, the FCW generates false and nuisance alarms, or cannot indicate some dangers. These critical situations could lead to unsuitable reactions and diminish acceptance if drivers have a poor understanding of the system's operations. This research aims at evaluating the benefit of familiarization with these situations. In a simulator study we compared drivers' behavior and their acceptance according to whether they used the system in a familiarization session. Results show that familiarization led to better understanding of the FCW, thus making driver/system interactions more effective and safer. However, familiarization had no effect on drivers' acceptance and even decreased their confidence in self-performance. We addressed practical applications for the deployment and rollout of FCW systems.
