The Catchment After Midnight

Afterglow Isochrones on Phosphorescent Shared Paths Under Part-Night Lighting

A research poster from the School of Underlying Conditions follows the photoluminescent shared paths of a suburban precinct that switches its streetlights off from 00:30 to 05:00, logging afterglow on 212 segments across 38 spring nights and redrawing each local centre's 800 m walkable catchment at half-hour cross-sections. By 03:00 the three catchments hold 58%, 43% and 20% of their lit-hours area, and the segments under heavy street-tree canopy go dark first, among them 71% of the planning scheme's green links by 02:30.
