Access to Public Transport
summary
Project measures how many people live within 500 m walk of a frequent public transport stop, using cleaned GTFS schedules, OpenStreetMap walking networks and Statistics New Zealand population meshblocks. Code uses GTFS kit to identify frequent stops, calls Mapbox Valhalla isochrones via routingpy for 500 m walking catchments, dissolves polygons and intersects meshblocks to count people. Result: automated pipeline outputs a headline number (Wellington ~78,411 people with frequent access) and maps; tooling works but OSM edits and threshold choices change results.
