I have sometimes wondered whether harvesting GPS traces would help with this
task. If every trace shows turning left at the junction, flag a warning for
somebody to check whether a turn restriction needs to be added. But to do that
we would need a bigger collection of traces, appropriately tagged to show which
are from motor vehicles.
In theory, Mapdust (Skobbler users' feedback) ought to be able to help
here. In practice it isn't quite there yet - sorting the wheat from the
chaff can be a challenge.
For example with this one:

it really isn't obvious which is the wrong turn that wasn't allowed, or
whether the problem is actaully entirely different.
Cheers,
