Many transit agencies publish open access feeds of real-time fleet locations for use by application developers to deliver mobile navigation services. However, by collecting a transit data feed over time, we demonstrate how to recreate retrospective, routable transit networks that are useful in answering network performance and accessibility research questions. In this research we develop an end-to-end GIS toolchain for 1) downloading and storing a transit data feed, 2) coercing the collected spatiotemporal database into a retrospective transit schedule adhering to the General Transit Feed Specification (GTFS) data standard, and 3) creating a routable transit network with time-dependent travel times in Esri ArcMap. We further demonstrate how this toolchain can be used to identify discrepancies between scheduled and actual travel times on the network and motivate the usefulness of this approach through an accessibility analysis.
