Transit-oriented development (TOD) aims to create pedestrian-friendly neighborhoods around transit hubs to improve urban mobility. However, it often overlooks the specific transportation needs of people with limited mobility. This study adopts Sen’s capabilities approach (CA) and the concept of conversion factors to analyze how ordinary pedestrians, the elderly, and wheelchair users transform planned catchment areas into functional capability spaces. Our focus is on understanding these conversion factors, which highlight both environmental and individual constraints when converting resources into capabilities. Our findings reveal significant disparities in walking environments between the initially planned and the realized catchment areas, as well as disparities between individuals with and without physical limitations. This study complements established quantitative methods, enhancing the application of the CA for evaluation. It provides a more precise assessment of pedestrian infrastructure and advocates for inclusive design improvements in the context of TOD cities and an aging population.

交通导向型开发（TOD）旨在在交通枢纽周围创建步行友好型社区，以改善城市交通。然而，它往往忽视了行动不便人士的具体交通需求。本研究采用森的能力方法（CA）和转换因子的概念来分析普通行人、老年人和轮椅使用者如何将规划的集水区域转变为功能能力空间。我们的重点是了解这些转换因素，它们突出了将资源转换为能力时的环境和个人限制。我们的研究结果揭示了最初规划的和已实现的集水区之间的步行环境存在显着差异，以及有身体限制和没有身体限制的个人之间的差异。这项研究补充了已建立的定量方法，增强了 CA 评估的应用。它对行人基础设施进行了更精确的评估，并倡导在 TOD 城市和人口老龄化的背景下改进包容性设计。
