The Effects of Truncated Dome Detectable Warnings on Travelers Negotiating Curb Ramps in Wheelchairs

Abstract

Truncated domes on curb ramps benefit travelers with visual impairments. However, concerns associated with the safety and negotiability of such detectable warnings for other travelers have resulted in much controversy. The findings of the study presented here indicate that detectable warnings did not adversely affect the negotiability of ramps by the 21 participants who ambulated by wheelchairs.
