An examination into the efforts of the Americans with disabilities act towards curb ramps and their usability
Keith Paul Touchet, Fall 2004
Brief:
Curb ramp construction standards are a relatively new technical area. Current standards have not been effective in the performance of curb ramps. However, the majority of ramp requirements that deal with sidewalks and streets are pre-Americans with Disabilities Act requirements. Because of conditions that include sidewalk height and width, current curb and gutter construction, reverse street slope, and obstructions such as lights, signs, and other traffic requirements, the value of existing curb ramp standards is questionable. A ramp can meet standards and yet be nonperforming for user access. The increase in effectiveness of current curb ramps in relation compared to past curb ramps has not been overwhelmingly successful. Further complicating the use of curb ramps is the difficulty of understanding performance for the user with a disability, the economic impact of ramp performance, and the construction quality of the ramps. As in other construction areas, the potential solutions require alternative designs and improved construction techniques. One important aspect in dealing with curb ramp performance is communication and collaboration among designers, contractors, and users. The author has studied the macro problem of maximizing design and construction and of minimizing the risk issues that increase the performance of the curb ramp access. The data acquired shows a need for a significant change in both curb ramp design and construction techniques.
