Each point is a city. x — land area (km²) from which the CBD is reachable within 60 minutes by car; y — the same by public transit. Diagonal guides mark where transit access would equal 100%, 10%, and 1% of car access. Use the search box (or click points) to highlight specific cities — everything else dims.
Accessibility-zone areas after Conwell, Eckert & Mobarak (NBER WP 30877): area reachable within 60 minutes of the CBD at Wednesday morning rush. Jan 2023 = paper's published values (8:30 AM arrival); Jul 2023 = independent re-pull (8:45 AM arrival). Hover any point for city values; on log axes, vertical distance to the 100% guide reads as each city's transit deficit in orders of magnitude.
