The model: Maximum speeds per road type: the five-rung ladder

The ladder (Book p.117-118): woonerf 15 · 30 km-zone 30 · built-up area 50 · outside the built-up area (ordinary roads) 80 · autoweg 100. The autosnelweg sits above it at a standard 130 — see the sister atom maxima.daglimiet_100 for that number's day/night nuance.
