What a sleep zone is
A sleep zone is a point marking where people sleep or where quiet is expected — a bedroom side of a building, a care room, a nursery. Each point shows a small quiet zone around it on the map.
- It marks a place to be quiet near, not a place to avoid entirely.
- Typical cases are bedroom façades, care homes, hospitals, and hotels.
- Like parking, a sleep zone stands on its own and needs no entrance first.
