A One-seat Ride Coverage Ratio using Administrative Origin Destination Data

Much remains to be known about the geographic areas in regions that are well (or poorly) served by one-seat transit – direct service where users do not need to conduct transfers. We describe geographic access to one-seat service, by advancing the framework of a spatial coverage ratio for transit when accounting for commuter flows as reflected in administrative origin-destination data. Our methodology integrates relatively simple spatial approaches with open data, allowing transit providers to modulate thresholds for one-seat service. In doing so, operators can develop new priority areas for intervention and line adaptation.
