Pedestrian cognition affected by the Distribution of night lighting morphology against the spatial layout of the street

指導教員: 埼玉大学大学院理工学研究科教授 窪田陽一This research intends to clarify optimum illumination patterns of urban nightscape. For this purpose the lighting distribution and its related effect were classified, while giving parallel consideration to the spatial layout of the street. The experimental work was carried out by choosing 33 road segments, lying between the East Exit of Omiya Station and the Hikawa shrine as a model space. Spatial layouts of the streets were classified considering street depth(d), building height(h), (d/h) ratio and the number of shops. Using photographic images, the illumination condition of area was surveyed for the characteristics of the lighting apparatus. Influential factors related to the lighting distribution and it’s effect were identified by classifying the foresaid images based on the similarity of street characteristics. In the next stage, real experience in an illuminated space was investigated by focusing on the ease of eye catching of the lighting and the lighting effect on the potential places of attraction. Finally, impact of lighting distribution was evaluated by rating the images on seven psychological parameters. Results confirmed that the experience of the illuminated space would differ as the spatial layout changes
