[Talk-scotland] Edinburgh 20mph Limits

[Donald Noble]

Thanks for the comments.

Having had a look at a few more roads in Morningside on a detoured route
back from uni tonight, I tend to agree with needing to survey this. There
are some differences with the online GIS, e.g. west end of Cluny Gardens,
and there is no signage on Merchiston Bank Avenue which joins onto a 30mph
road, despite it being shown blue. I would be surprised if anyone could do
30 on this dead end street though!

With that in mind, it would be nice if you could set up the task Chris, so
that we can co-ordinate efforts. As Robert says, this is more daunting than
the previous one! I have logged in to the task manager, but not done
anything yet.

As for copyright, I don't think there should be any issues with using the
council map as a list of streets to check. It might be possible to get this
from the council, or scrape the TROs, but that will delay things a lot.

Cheers, Donald
