15-Minute City Accessibility and Facility Location Using OSM and ML

Can people in Zone 13 Adyar, Chennai, reach a school, clinic, pharmacy, grocery, park and bus stop on foot in 15 minutes? On the OpenStreetMap walking network, 59.3 % of the modelled 905,973 people reach all six mapped types, against 86.0 % by straight-line buffers. A check with Overture places moves the same number to 85.4 %: a gap on the map means no facility is mapped, not that none exists. Greedy, a genetic algorithm and exact solvers choose new clinic sites; with Overture clinics added, the same five sites newly reach no one, so the sites need field checks before anything else.
