Junhao Wang's research dataset proposes the Activation-Impedance Decay Model (AIDM) for analyzing intra-urban population spatial interactions. The 8.9 MB collection includes model code, data, and results, last updated in April 2026. It provides a framework for modeling non-monotonic distance-decay patterns by integrating urban functional heterogeneity and distance friction.
Primary content appears to be a research model and its outputs; users should expect a mix of code, figures, and likely derived data tables rather than a single large raw dataset.
