Wang, Liao, Lyckvi, and Chen studied the different implications of using visual and auditory alarms.  They determined via “data from two simulator studies . . . where the visual vs. the auditory modality was used to present the same type of advisory traffic information under the same driving scenarios. . . . that modality influences the drivers' behaviour patterns significantly. Visual information helps drivers to drive more accurately and efficiently, whereas auditory information supports quicker responses. This suggests that there are potential benefits in applying both modalities in tandem, as they complement each other.”
