Ive read back through this discussion and i really cant see an answer..
to my mind, traffic is a bit like water.. it will always find the path of least resistence...
dinas powys is right in the path of many hundreds, possibly thousands, of commuters heading in and out of cardiff.
Until recently i was lucky enough to have been able to work from home. i used to watch all the sheep going to work, sipping a cup of tea and replying to emails. but now, im one of the sheep. again.
from a selfish point of view i would love the old part of the village to be pedestrianised but in reality it would not solve a problem, just move it.
i think the only way is to improve public transport...i know i had a nightmare when i used it last. but it has to improve, it HAS to work!... most of the cars i follow to work have 1 person in it, just like me.
