Abstract

Spatial equality analysis is useful for urban designers and policy makers to produce and/or adapt urban services provision, while supporting the pursuit of the public interest in the urban design process. This research focuses on urban public facilities (UPFs), the most relevant physical elements serving the public interest, and proposes a multi-scale methodology from a practical perspective to understand and foster the spatial equality of UPFs. Using Shenzhen to test the approach, this research first investigates the density and aggregation of UPFs at the district level to recognize how developing differentiations and social context act on the spatial patterns in UPFs. Second, the accessibility of different types of UPF are measured at the sub-district level which emphasizes the spatial impedance between demand and supply and the availability of services. Then, we draw location-specific design strategies for better spatial equality at a site scale. The results show "cross-district impact" plays an important role in influencing overall spatial equality. Also, sufficient transportation networks, road configurations, and the diversity of UPFs could significantly improve service capacity and impact the achievement of spatial equality. This paper draws attention to the improvement of spatial equality and can contribute new insights to the interpretation and measurement of the spatial equality in urban design debates.
