This research aims to construct an equity assessment framework for perceived accessibility: using the Gini index and Comparison index to measure calculated transport equity; measuring perceived transport equity based on people’s perception of public transportation services, affordability, and accessibility distribution. Through an empirical study of affordable housing and commercial housing residents in Nanjing, it is found that there is no significant difference in the Gini index between the two types of residents. However, the Comparison index results show that the accessibility inequality between the two types of residents in the central urban area is more significant. Moreover, there is a certain correlation between the calculated and the perceived transport equity measurement results. Therefore, this study believes that adding perceived transport equity to existing frameworks is important because it can more comprehensively consider personal life experiences.</div></div>","PeriodicalId":23277,"journal":{"name":"Transportation Research Part D-transport and Environment","volume":"146 ","pages":"Article 104908"},"PeriodicalIF":7.3,"publicationDate":"2025-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144605067","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
