@cmconseils That's "desire lines".
There was a University a while ago that build some new buildings on Campus and left the ground in between untreated for a while. Later they paved ways, where the desire lines showed up.
Might be the more natural and better way to treat human needs.
@thorsten4future @cmconseils That is my life's philosophy. I think about this comic every time I take a shortcut. If you find your park having a two lane shortcut over the grass, you have done a bad job planning that park for the actual users.
I would try to plan out where people will be walking/biking and do those as roads. Then I would wait a year to see where the grass disappears and make that into gravel roads at least. I have seen a few places where that has happened around here.
