Where the numbers come from
Stedsvalg uses open data only. I publish derived area values and not the downloaded raw datasets.

What is not settled
The city’s map layer for basic statistical units gives no licence in its metadata. I use it only to link cells to districts.
Bane NOR’s noise data has no explicit standard Norwegian licence. It is therefore used only as supporting evidence and not as the sole basis for the noise measure.
This overview is technical documentation and not legal advice.
Research behind the trade offs
The weight on transfers and walking draws on work from the Victoria Transport Policy Institute and peer reviewed studies of transfer penalties. The public transport curves follow the Norwegian Public Roads Administration guide N-V123 and TØI report 858. The nature measure draws on Natural England’s Accessible Greenspace Standard.
