Public lighting specifications for visually impaired people: results from an experiment
Visually impaired people face important difficulties walking at night in cities. This led the city of Lyon to wonder about possible public lighting solutions better adapted to the expectation of this specific population. A group composed of multi-disciplinary experts in the field of lighting was formed to launch a field experimentation involving 62 visually impaired people and 11 well-seeing people. These observers were asked to assess the quality of various lighting schemes, which were proposed on a 400 m long itinerary. Many aspects were explored such as the role of public lighting installations, the urban street furnishing, the road markings, the readability of street name panels, the road surface photometry, the quality of light sources, and the light coming from the stores. This study led to the establishment of some suggestions of recommendations, dealing with the illuminance level and uniformity, the luminaire photometry, the spectrum of light sources, the lighting contribution from the ground or from stores, the contrast to detect the obstacles, the detection of crosswalks and bus station, the readability of street panels, the luminous road marking, the publicity.
