Planning Artificial Light at Night for Pedestrian Visual Diversity in Public Spaces

This article makes the case for addressing pedestrian visual diversity when planning artificial light for public spaces at night, by drawing upon original findings from an exploratory study where twenty-one open-ended interviews were conducted with experts in the fields of artificial lighting, urban planning and health studies. Specifically, this article provides (1) the introduction of the concept of pedestrian visual diversity, defined as the condition, capabilities and needs of visually impaired pedestrians, (2) a systematization of overlooked issues in the planning of artificial light for visual diverse pedestrians in public spaces and (3) the proposition of a participatory framework for the application of lightwalks as an experiential method for involving visual diverse pedestrians in the data collection on and analysis of artificial lighting in public spaces at night. In conclusion, it identifies five strands for further research at the nexus of pedestrian visual diversity, public space and night studies for inclusive light planning.
