Built environment and autism: towards a set of spatial requirements for autism friendly cities

Abstract

Abstract Background The opportunity for people functioning in an atypical way to autonomously and fully interact with the city is often compromised or denied, due to the gap between their specific spatial needs and the physical and functional organization of the urban environment. The need to reconsider the living environments taking into account the vast diversity of people gained an increasing importance in the overall debate and specifically in the field of urban planning and design. The research aims at investigating the relationship between the urban environment and people with Autism Spectrum Disorder (ASD). Methods A scoping review of current available original studies research exploring the relationship between autism and built environment was conducted. PubMed, Scopus, PsychInfo and Web Of Science where searched. Studies included provided spatial requirements for designing autism friendly environment. Results In total, 801 studies were identified and 22 were included. Current researches and applications investigating the role of spatial configuration as a means for improving the autonomy of people with ASD almost exclusively focus on closed and dedicated spaces (residences, schools, care facilities, healing gardens) mostly devoted to children. Starting from this and the data collected, a first set of enabling urban spatial requirements addressing the atypical urban functioning of people with ASD - the reduction of sensory overload and the use of visual supports - in order to promote their possibility to walk autonomously and safely across the everyday city is proposed. Conclusions Despite the wide variability of the spectrum which makes it very difficult to define effective design criteria for all people with ASD, it's possible to identify a set of recurrent spatial needs. Furthermore, designing cities for people with ASD can also contribute to healthier and more inclusive urban environments for other groups of vulnerable inhabitants.
