The Painted Kerb Number as Courier Wayfinding Device

A paper from the School of Continuous Improvement allocates a painted kerb house number to 23 of 46 suburban streets by fixed rota and reads it against 11,461 courier scanner attempts over sixteen weeks, finding missed deliveries at 4.3% of attempts on numbered streets against 4.4% on unnumbered ones, and no difference in redirections, time to first knock or stencil digit height. The University's residence-delivery contract now fixes every kerb number as first painted, seventeen incorrect stencils included, with no correction permitted.
