Zusammenfassung	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.	A walkability index measures how well a neighbourhood's built environment supports walking, by combining a small set of land-use and street-design variables into a single score. The influential index developed by Lawrence Frank and colleagues sums standardized measures of residential density, land-use mix, street connectivity, and retail floor-area ratio, giving extra weight to intersection density because connected street grids most strongly enable walking. Consumer tools such as Walk Score popularized the same idea by scoring an address on the proximity and variety of nearby destinations, making walkability a routine input to planning, public health, and real-estate analysis.
