Some cases of lit=yes are clear (direct lighting of street/footway by lamps)
Some cases of lit=no are clear (no lighting whatsoever)
But in cities there is also often strong or weak ambient light, for example:
- carriageway is directly lit with so powerful light that spillover light
makes footway well lit - clearly lit=yes
- spillover light is quite dim but enough to comfortably walk - also lit=yes
- there is some ambient light, but not enough to walk without own
source of light - lit=no
- there is an ambient light, one can carefully walk, but only slowly,
people with poor eyesight needs their own source of light - lit=no (?)
Overall, I am considering adding to https://wiki.openstreetmap.org/wiki/Key:lit <https://wiki.openstreetmap.org/wiki/Key:lit>
recommendation to consider "is it necessary to bring your own light source to see it properly"
as recommended threshold for footways/paths.
Any problems with that or ideas for a better threshold between lit=yes and lit=no?
disclaimer: I am trying to make lit=yes/no definition more precise as part of my grant
