Assessing spatial configuration of barrier-free facilities from the perspective of age-friendliness: A case Study of Beijing, China

Enhancing urban inclusivity is a crucial task for sustainable urban development. One key challenge is to create seamless and accessible urban space that caters to the mobility needs of people, especially the elderly. Addressing this pressing challenge requires a comprehensive overview of barrier-free facilities (BFFs) configuration within cities. In this study, we propose an integrated framework for assessing the BFFs in Beijing by leveraging open BFFs data and mobile phone data. The proposed framework encompasses considerations of spatial distribution, accessibility, and supply-demand patterns of BFFs. Our findings reveal the significant agglomeration and heterogeneity of BFFs in Beijing, as well as serious spatial and social inequalities. Furthermore, the supply-demand relationship of BBFs in Beijing is relatively good, with 77.8% of supply-demand balanced areas. Overall, our study provides a holistic understanding of the BFFs within Beijing, offering valuable insights for informed decision-making in inclusive city planning and development.
