Perceived lighting qualities and pedestrians’ performance

Johansson, Maria LU and Rahm, Johan LU (2015) In CIE 216:2015
Abstract
Street lighting is an essential feature of pedestrian paths that may increase the amount of walking. This study aimed to identify associations between perceived lighting qualities, and experience of the lit environment and performance of critical tasks. In a full-scale laboratory 89 participants walked along a pedestrian path with three different outdoor lighting applications (CDM and LEDs). After each walk they rated the perceived lighting qualities, perceived visibility and affective experience of walking in the lit environment. Walking speed was measured and obstacle detection, sign-reading and facial recognition were tested. Multiple regression analyses suggest that photometric measures are required to guarantee that pedestrians’ can... (More)

After each walk they rated the perceived lighting qualities, perceived visibility and affective experience of walking in the lit environment. Walking speed was measured and obstacle detection, sign-reading and facial recognition were tested. Multiple regression analyses suggest that photometric measures are required to guarantee that pedestrians’ can orientate and safely move after dark. Perceived lighting qualities may however account for individual differences in the assessment of one and the same lighting application with regard to perceived visibility and the affective experience of walking in the lit environment and may thereby affect walking.
