Abstract : The aim of the project ROADSENSE ANR-10-VPTT-010-01 is to define a driver assistance that prevents involuntary out of traffic lanes. A rumble strip producing a vibratory and sound alarm provides this help to get back on the road. Based on an objective measurement using simple reaction time, the perceptual influence of the vibratory component on the audio component of alarms produced by rumple strips was studied. Two situations were compared: the first one with sound only and the second one with sound and vibration. During this experiment, participants were placed in a semi-realistic driving situation and were asked to press a pedal as soon as possible when they perceived an alarm. Audio-vibration alarms were synthesized by extracting a signal pattern from real recordings of sound and vibrations produced by rumple strips. This pattern vibration and sound was repeated using three different inter onset intervals IOI. Values of reaction times show neither an effect nor an interaction of the vibration component on the audio component of the alarm. However, the influence of the IOI is important; shorter is the IOI better is the reaction time. This result is in agreement with previous results from the literature.
