Public transport can look fairly shared out across a region and still leave particular places badly served. This map divides the Pearl River Delta into 4,531 cells of 3 km by 3 km across eight cities and compares, for each cell, its share of residents with its share of public transport service. Choose a view: the first classifies cells by whether service falls short of or exceeds demand and by how much service they have in absolute terms, so that cells with both a shortfall and little service stand out, and shows the gap score and service intensity behind that classification. The second shows where, locally, features of a place such as residential density, intersections, bus stops or distance to the metro go with a larger or smaller gap. Switch between all housing and indemnificatory housing, the paper’s low-income housing group, to see how the picture changes for the people with fewer alternatives, and highlight a city to read its equity indices from the paper.
This map accompanies the paper Zhu, Liu and Bao (2026), “A cross-level diagnostic framework for spatial equity of public transportation services: Supply-demand mismatch and influencing factors in the Pearl River Delta”, Cities, 179, 107714. It shows only grid-level results presented in the paper.
