Determining whether a public transit network provides equitable accessibility to different population segments is an ongoing challenge. The purpose of this work is to inform the development of more robust transit equity analyses than are currently conducted. To this end, the authors develop and demonstrate the utility of a highly spatially and temporally resolved accessibility indicator with an application to the Phoenix, Arizona metropolitan area’s multimodal transit system. The indicator is calculated using publicly available data, including the US Census Bureau’s Longitudinal Employer-Household Dynamics dataset and transit route and schedule information in the General Transit Feed Specification (GTFS) format. This measure has clear application to the service equity analyses required of the Federal Transit Administration’s (FTA) fund recipients. Previous academic work on accessibility has not translated well to practice in part because the calculation of accessibility relied upon regional travel demand model outputs that were difficult to obtain. This work thus fills an important gap in the literature and practice by tying advances in the academic literature to FTA-mandated analysis with publicly available data.
