Urban Mobility Index
An ML experiment predicting walkability from bus-stop and intersection densities across 774 neighborhoods in nine cities - and an honest account of where it works (the cities it trained on) and where it doesn't (the ones it hasn't seen).
Quality of Life of NYC Children
Most quality-of-life indices don't really account for kids. We built one that does - a 0–10 score for children across all 55 NYC PUMAs that combines infrastructure access, economic pressure, and environmental quality, framed by who actually lives in each district.
