Assessment of Accessibility for Visually Impaired Users in Public Buildings

Abstract

Accessibility for visually impaired users is an important consideration in the design and management of public buildings because visual limitations can affect navigation, orientation, safety, and independent movement. Public buildings such as government offices, educational institutions, healthcare facilities, commercial centres, and transport facilities serve diverse users and should provide environments that can be accessed with minimal barriers. Inadequate consideration of visual accessibility may result in confusion, dependence on assistance, and increased risk of accidents. Assessing accessibility for visually impaired users is therefore essential for promoting inclusive and user-responsive public buildings. This study assesses the accessibility of public buildings for visually impaired users, focusing on architectural and environmental features that support independent navigation and safe use. It examines entrances, circulation routes, stairs, ramps, corridors, lifts, doors, sanitary facilities, signage, and major functional spaces. Particular attention is given to tactile indicators, visual contrast, lighting, audible information, surface changes, handrails, signage, and the clarity of spatial organization as factors influencing accessibility for people with different levels of visual impairment. Effective accessibility requires clear and predictable circulation systems that allow users to identify routes, spaces, and destinations with minimal difficulty. Tactile paving, contrasting surfaces, appropriately positioned handrails, audible signals, and tactile or raised-letter signage can support orientation and navigation. Adequate and well-distributed lighting can also improve visibility for users with partial sight, while minimizing excessive glare and confusing visual patterns. The study therefore considers how these design features can work together to create safer and more navigable public environments. Wayfinding is particularly important in large or complex public buildings where users may need to move between multiple functional areas. Logical spatial organization, consistent signage, identifiable landmarks, clear circulation routes, and appropriate information systems can reduce navigational difficulties. The study also considers the importance of unobstructed pathways and the proper positioning of furniture, fixtures, and other elements that may create unexpected hazards for visually impaired users. Despite the importance of visual accessibility, public buildings may contain barriers resulting from poor signage, inadequate lighting, inconsistent tactile information, obstructed circulation routes, inappropriate surface finishes, and limited awareness of inclusive design requirements. Existing buildings may also present challenges when accessibility features were not incorporated during their original design. Addressing these deficiencies requires systematic accessibility assessments, user-centred design, appropriate retrofitting, effective maintenance, and greater consideration of sensory accessibility in architectural planning and building management. The study concludes that accessibility for visually impaired users depends on the integration of physical, sensory, and informational features that support safe and independent navigation. Appropriate tactile elements, visual contrast, lighting, audible information, clear signage, and well-organized circulation systems can reduce barriers and improve user experience. The findings are expected to provide useful guidance for architects, engineers, facility managers, public authorities, and building owners in assessing existing facilities and developing more inclusive public buildings.
