A survey was carried out in Rome to investigate whether street luminance affects pedestrians’ comfort, visibility and perception. Forty people walked five roads and assessed on a questionnaire their walking comfort, visibility of people and background, perception of lighting intensity and uniformity. Results indicated that walking comfort was affected by mean luminance of whole scene, of sidewalk, of lateral wall and of human body; luminance also influenced the perception of street lighting intensity and uniformity and, to a lesser extent, the visibility of other people and of background.
