N2 - Understanding and predicting urban vitality—the intensity and diversity
of human activities in urban spaces—is crucial for sustainable urban
development. However, existing studies often rely on discrete sampling
points and single metrics, limiting their ability to capture the
continuous spatial distribution of urban vibrancy. This study introduces
the UVPN (urban vitality prediction network), a novel deep-learning
architecture designed to generate high-resolution predictions of static
and dynamic vitality at regional scales. The architecture integrates two
key innovations: a SE (squeeze-and-excitation) block for adaptive
feature recalibration and an RCA (residual connection with coordinate
attention) bottleneck for position-aware feature learning. Applied to
New York City, UVPN leverages diverse urban morphological features such
as streetscape attributes and land use patterns to predict continuous
vitality distributions. The model outperforms existing architectures,
achieving reductions of 34.03% and 38.66% in mean squared error for
population density and pedestrian flow predictions, respectively.
Feature importance analysis reveals that road networks predominantly
influence population density, while streetscape features strongly affect
pedestrian flows, with built density and points of interest
contributing to both dimensions. By advancing urban vitality prediction,
UVPN provides a robust framework for evidence-based urban planning,
supporting the creation of more sustainable, functional, and livable
cities.
