可达性指标越来越多地被用作探索交通系统和政策的社会影响的工具。然而，很少有关于无障碍环境的实证研究涉及不同发展水平国家的城市之间的比较，特别是在全球南方和北方。本文试图弥合这一差距，专注于两个非常不同的，但类似的规模，大都市地区：圣保罗和伦敦，我们开发的比较metrs.These指标被用来识别不同的职业群体的模式（用作代理社会经济群体），并讨论公交可达性的不平等。对具有特殊特征的城市区域的比较研究所提出的问题进行了讨论。本研究将大都市区的结果与其他大都市区的结果进行对比，探讨各大都市区的公共交通系统特征和居住地与工作地点之间的空间不匹配与不平等之间的关系，并将群体的状况用Lorenz曲线表示，同时也揭示了不平等的可比性研究所应采取的新策略。洛伦兹曲线和基尼系数的结果显示，圣保罗的交通可达性不平等程度大于伦敦。拟议的群体代表性丰富了作为支持交通规划工具的可比性视角。
Accessibility metrics have been increasingly employed as a tool to explore the social impacts of transport systems and policies. However, few empirical studies of accessibility involve comparisons between cities from countries with different levels of development, in particular, across the Global South and North. This paper attempts to bridge this gap by focusing on two very distinct, but similarly sized, large metropolitan regions: Sao Paulo and London, for which we develop comparative metrics.These metrics are used to identify patterns for different occupational groups (used as a proxy to socioeconomic groups) and discuss transit accessibility inequalities. The issues imposed by a comparative study of urban regions with particular characteristics are discussed. The study applies the results of one metropolitan region to contrast with the other and explore how characteristics of each region's public transport system and spatial mismatch between residential and workplace locations are related to inequalities.Group's condition was represented in the Lorenz curve, also revealing a new strategy to be adopted by comparability studies on inequalities. The results from Lorenz curve and Gini coefficient reveal larger transit accessibility inequalities in Sao Paulo than London. The proposed group representation enriched the comparability perspective as a tool to support transport planning.
