But what if there are no crossings marked? Do we have to invent
crossings then ? (e.g. near each junction)
It is not uncommon to have such a network of sidewalks without
People are allowed to cross everywhere then.
There isn't even always a lowered kerb for people in wheelchairs. If
the are lucky, they can use the connection of a driveway with the
street, as those usually have a lowered kerb.
