THE EFFECT ON DRIVING BEHAVIOUR OF REACTION TO AN UNEXPECTED AUDITORY STIMULUS IN A SIMULATOR ENVIRONMENT

Vehicle safety technologies are becoming more advanced, and now include driver warning systems. An auditory warning is thought to be preferable to a visual warning for two reasons: no failure and no time-lag in its perception by the driver. In this study, how an unrelated auditory stimulus and driver response (switching) affected driver reaction time (RT) were examined in comparison with a visual stimulus in a simulator environment. The onset-asynchrony of sounds accompanied by a visual stimulus was varied between -0.5 s to +0.5 s. Reaction times to visual stimuli accompanied by a sound were compared with reaction times to a silent visual stimulus. The results can be categorized by type of asynchrony into three cases. It is expected that this warning system will reduce driver reaction delay in a traffic environment. For the covering abstract see IRRD E102946.
