Occupied, Not Offered

A Four-Kind Occupancy Taxonomy of the Morning-Bus Priority Seat, Adopted as the Network's In-Use Rule

A research poster from the School of Emergent Priorities sorts occupied priority seats on the morning bus into four kinds --- offered, claimed, bagged, and filled-unoffered --- coded from 412 observations across 22 services. Filled-unoffered is the modal kind at 47 per cent, and standing instruction 2026/14 adopts it as the network's in-use category, so kneeling-bus allocation follows whichever routes keep those seats fullest.
