The effect of visual, haptic, and auditory signals perceived from rumble strips during inclement weather

Rumble strips (RS) offer ideal conditions for multimodality research. Designed to reduce crashes and alert drowsy or inattentive drivers, their effectiveness in crash reduction is not questioned but little is known regarding how information from tactile vibrations and auditory rumbling is integrated during low-vision driving conditions. In this paper, we report descriptive data related to participants' perceptual experience while driving on a RS road during a snow storm, as well as data collected from participants driving in a simulated snow storm environment, and suggest future research perspectives.
