摘要： 选取来自国际学术期刊的论文，以概述形式对城市交通理论方法、实证分析等学术研究成果进 行总结性介绍，旨在增强城市交通业界和学界对国际学术动向和研究热点的关注，促进学术交流。本 期精选的论文聚焦交通公平及可达性。该研究对传统的交通公平研究方法进行了深入探讨并提出质 疑。以往的研究往往基于群体的平均可达性，掩盖了群体内部的异质性。同时，仅仅比较不同群体间 的可达性水平差异，并未深入探讨其可达性是否足够——即可达性水平是否足以支持人们参与日常生 活中的各类活动。为此，提出一种新的分析方法——可达性的足够性分析，这种方法通过设定一个明 确的足够可达性阈值来解决上述问题。通过对美国49个主要都市区进行的实证研究，该研究展示了 传统差异性分析的局限性，并通过足够性分析揭示了交通不公平现象。

Discussion on Equity in Accessibility: Moving from Disparity to Insufficiency Analyses

Abstract： A literature review of selected articles from international academic journals is presented to summarize research findings, theoretical approaches, and empirical analysis of urban transportation. The aim is to enhance the communication between industrial and academic fields, highlight international research focuses, and promote academic exchange in urban transportation. The selected paper in this issue concentrates on transportation equity and accessibility. This paper thoroughly examines and questions the traditional methods employed in transportation equity. Previous studies often relied on the average accessibility of groups, thereby concealing the heterogeneity within these groups. They only compared the differences in accessibility levels among different groups without delving into whether the accessibility is sufficient—i. e., whether the accessibility levels are adequate to support the participation of people in various daily activities. To address these issues, a new analytical approach is proposed—the analysis of accessibility deficiency, which can address the aforementioned issues by establishing a clear threshold for sufficient accessibility. Through empirical research conducted on 49 major urban areas in the United States, the study demonstrates the limitations of traditional disparity analysis and presents instances of transportation inequity through sufficiency analysis.
