An interactive web application for multi-modal accessibility analysis. Pick an origin on the map and see what's reachable by transit, walk, or car within a chosen time budget, with a 6-category POI accessibility score (healthcare, education, grocery, parks, public services, employment). The Full Map tab colors every populated hex in the city by what's reachable from it — transit reach, car reach, or the signed gap between them on a diverging palette. The Graphs tab summarises inequality of reach with a Lorenz curve and Gini coefficient. Built from public GTFS feeds, OpenStreetMap, and WorldPop population data.
