Three-dimensional Spatial Network Analysis and Its Application in a High Density City Area, Central Hong Kong

Zhang Lingzhu, Alain Chiaradia

Keywords: Three-dimensional Built Environment; Spatial Design Network Analysis (sDNA); Human-centred; High Density; Pedestrian Network; Urban Design; Hong Kong


This paper proposes a new GIS based spatial design network analysis (sDNA+) that can be used in three-dimensional built environment. Spatial configuration and its relation to pedestrian movement are quantitatively analysed in the case of Hong Kong Central area. The comparison between outdoor only and indoor + outdoor 3D pedestrian networks shows that it is unrealistic to study the multilevel pedestrian network in high density built environments by only considering the outdoor pedestrian network. Indoor + outdoor 3D pedestrian network helps designers and researchers to decode human-centred spatial configuration and pedestrian activity patterns.
