- Abstract
- In Belgian artificially lighted urban environments like city centres and urban streets, the lighting conditions are mostly mesopic at night. In order to study the pedestrian's perception, his/her whole visual field has to be analysed. The Esterman grid has been chosen to draw luminance and attention maps. The luminance maps are provided by a per-pixel analysis of high dynamic range images whereas the attention maps are generated by a mouse-tracking test. The comparison of both maps reveals the luminance level impact on pedestrians’ attention. Fifty-eight observers tested twelve urban scenes from the patrimonial city of Mons, Belgium. Considering the spectrum of the light source and the typology and materials of the urban environment, this work demonstrates the importance of the mesopic range of luminance in the visual field of a pedestrian. Moreover, it presents new ways of selecting efficient lighting solutions that involve the study of the human retina and the environment materials.
