Panel-to-Service Agreement at 246 Suburban Bus Shelters Under Two Verification Regimes, 30 to 90 Days After a Network-Wide Timetable Change

A research poster from the School of Emergent Priorities audits the paper timetable panels at 246 suburban bus shelters across three depots at 30, 60 and 90 days after a network-wide service change, comparing the panel in each frame against the timetable actually in force. Agreement runs from 58.1 per cent at the first sweep to 68.1 per cent at the last, while the transport authority's information-currency indicator, assembled from crews' date-stamped installation photographs, records better than 99 per cent of shelters as current throughout. Adding a panel-content field to the crews' verification record produces a pooled difference of 2.4 percentage points, with a confidence interval spanning zero.
