Accessible design ramps are specifically designed structures that provide safe and easy passage for individuals with disabilities, elderly people, and those using wheelchairs. These ramps are crucial for ensuring equal access to buildings, public spaces, and transportation. They typically follow guidelines such as the Americans with Disabilities Act (ADA) or the European Standard EN 16538 to ensure compliance with accessibility requirements. Key features include a gradual slope, non-slip surfaces, and proper width to accommodate wheelchairs and other mobility aids.
