Ease and Equity of Point of Interest Accessibility via Public Transit in the U.S

The tool developed as a result of this paper analyzes the ease and equity of access to major POI categories (e.g. vaccination centers, grocery stores, hospitals) using public transit in major U.S. cities. We built an interactive website that enables easy exploration of current access equity and allows performing scenario analysis by introducing/removing POIs. Accessibility indices were calculated using a 2SFCA (2-step floating catchment area) approach, and ML methods were utilized for exploratory statistical analysis of the results.
