Investigating the spatiotemporal pattern between the built environment and urban vibrancy using big data in Shenzhen, China
Abstract Promoting urban vibrancy is one of the major objectives of urban planners and government officials, and it is linked to various benefits, such as urban prosperity and human well-being. There is ample evidence that built environment characteristics are associated with urban vibrancy; however, the spatiotemporal associations between built environment and urban vibrancy have not been fully investigated owing to the inherent limitations of traditional data. To address this gap, we measured spatiotemporal urban vibrancy in Shenzhen, China, using Tencent location-based big data, which is characterized by fine-grained population-level spatiotemporal granularity. Built environment characteristics were systematically measured using the 5D framework (density, diversity, design, destination accessibility, and distance to transit) with multi-source datasets. We investigated the spatiotemporal non-stationary associations using a geographically and temporally weighted regression (GTWR) model. The results indicated that the GTWR models achieved better goodness-of-fit than linear regression models. Built environment factors such as population density; point of interest (POI) mix; residential, commercial, company, and public service POI; and metro station were significantly associated with urban vibrancy. Time series clustering revealed spatiotemporal clustered patterns of the associations between built environment factors and urban vibrancy. To promote urban vibrancy with urban planning and design strategies, both the spatial and temporal associations between the built environment and urban vibrancy should be considered.
Highlights The spatiotemporal dynamics of urban vibrancy was measured in a high-density city. The spatiotemporal associations were investigated using GTWR models, and spatiotemporal clustering patterns were identified. Population density some POI factors, and metro station are associated with urban vibrancy. Building density, street intersection, urban greenery, and bus station are not associated with urban vibrancy. Urban planning should customize interventions for the spatiotemporal effects of the built environment on urban vibrancy.
