The book sets forth Illinois environmental accessibility standards for disabled persons based on observation and interview data. Photographs, drawings, and detailed floor plans are included in sections dealing with human data (including space requirements for maneuvering wheelchairs, color blindness, incontinence, and severe auditory or visual impairment); site development (including curb ramps, parking, and landscaping); building elements (such as entrances and doorways, elevators, communication and identification systems, and ground and floor surfaces); and building products (including supports and plumbing fixtures). Additional requirements for such specific building types as hotels, educational buildings, transportation terminals, and restaurants are considered. (CL)
