PoI-accessibility ranking and its spatial patterns for the six representative cities.

(a) Cities world-wide sorted in descending order of average PoI-accessibility weighted by population, with . (b-g) Heatmaps of values for the six representative cities at the intersection level. Points heatmaps are color coded by population-weighted (scale shown on the right): darker areas indicate better access to services, white areas have no (or a negligible number of) residents, and red areas represent nodes with no access to services. Maps contain information from OpenStreetMap and OpenStreetMap Foundation, which is made available under the Open Database License.
