 • Aim
         – Investigate how addition of artificially generated sound
           affects blind pedestrians’ detectability of hybrid electric
           vehicles (HEVs).
 • Relevance
         – Potential impact of hybrid and battery electric vehicles on
           mobility of blind pedestrians topic of interest in popular
           media.
            • Assume quieter vehicles may be more dangerous to blind
              pedestrians, who often rely on hearing vehicles to
              navigate and travel safely.

 • 14 legally blind adults attempted to detect
   3 vehicles at 2 test sites:
         – Vehicles:
                • Midsize HEV sedan.
                • Same make and model HEV sedan with Vehicle Sound for
                  Pedestrians (VSP) system.
                • Same make and model internal combustion engine (ICE)
                  sedan.
         – Test Sites:
                • University parking lot.
                • Roadway near busy interstate and street.

 • Detection Distance:
         – Vehicle:
                 • VSP vehicle detected significantly further away than HEV
                   but not ICE.
         – Test Site:
                 • Despite sound level difference between parking lot and
                   roadway, no significant difference.
         – No vehicle x site interaction found.
 • Noteworthy:
         – Improved crossing margin (from –0.4 to 2.1 s)
           with forward VSP.

       • HEV with VSP was detected at significantly
         farther distance than same HEV without
         VSP.
       • Equipping hybrid and electric vehicles with
         sound system that emits an alerting sound
         in certain low-speed maneuver conditions
         may contribute to the safety of blind
         pedestrians.
