Arc width is apportioned
dwellings in the catchment, not measured trips — no origin-destination
data exists here. Arc height is drawing, not data: it scales with the
hub's distance so the flat line to it reads as a reach. A hollow hub had
no residential street inside the ring, so it falls back to its SA2
centroid.
Gold and purple mark the busier
links only — normalised volume 0.55 and over, near 1,200 vehicles or 320
pedestrians a day, the local-street / collector boundary. Quieter links
inside the ring stay road- or foot-coloured. Gold is drawn converging on
the site to show which links feed it; that direction is illustrative — the
volumes are real, the inward direction is not measured.
