When surveying in Brum all the route refs are on the bus stop signs. So
thats why we put them on the stop (ie adding what it says on the ground).
It's also a lot easier to add the routes if you know which stops they go to
:-)

Forcing the shelter to be yes of no I find a useful check for situations
where I added data some time ago and need to go back and wrap up
verification. But I agree, its not something that needs to be "required"

I guess Christoph is going to need to deal with the West mids folks who have
the data imported without the bus_stop attribute and everyone else that
does.

Yep, there are lots of customary stops in the NaPTAN data in housing estates
which dont have any physical presence.
