Accessibility Equity Analysis

Accessibility equity analysis asks not just how much access to opportunities a place has, but how that access is distributed across people and social groups — who can reach jobs, healthcare, and education, and who is left behind. It pairs an accessibility measure, in the tradition formalized by Karst Geurs and Bert van Wee, with the distributional tools of inequality measurement: Lorenz curves, Gini and Palma indices, and comparisons between advantaged and disadvantaged groups. The result reframes accessibility as a question of fairness, revealing whether a transport or land-use arrangement concentrates reachable opportunity among the already privileged or spreads it equitably.
