论文摘要
公平获取基本兴趣点（POI），例如医疗机构和杂货店通过公共交通是一个关键的城市规划挑战。本文介绍了一种互动工具，可以分析美国主要城市此类访问权限的便利性和公平性。使用2步浮动集水区（2SFCA）方法，我们计算颗粒状可访问性指数，并在基于网络的交互式平台上展示它们。这项工作的一个关键贡献是场景分析功能，该功能使用户可以模拟添加或删除POI的影响并可视化可访问权益的变化。我们的分析揭示了人群群体之间的显着差异，我们进一步利用机器学习模型来证明可访问性得分与邻里种族组成之间的牢固，可量化的联系，从而突出了系统性的不平等。该工具为决策者提供了一个实用的框架，以制定更明智和公平的基础设施决策。
Equitable access to essential Points of Interest (POIs) such as healthcare facilities and grocery stores via public transit is a critical urban planning challenge. This paper introduces an interactive tool that analyzes the ease and equity of such access in major U.S. cities. Using a 2-step floating catchment area (2SFCA) approach, we calculate granular accessibility indices and present them on an interactive, web-based platform. A key contribution of this work is a scenario analysis feature that allows users to simulate the impact of adding or removing POIs and visualize the resulting changes in accessibility equity. Our analysis reveals significant disparities across demographic groups, and we further utilize machine learning models to demonstrate a strong, quantifiable link between accessibility scores and neighborhood racial composition, highlighting systemic inequities. The tool provides a practical framework for policymakers to make more informed and equitable infrastructure decisions.
