Hi, this is a complicated question and we didn't know which part to post it. The board seems well used by experts so we hope someone could give us thoughts or information.
We noticed on t.v. that the olympic area pavements seem to be laid with something like a cycle strip running along the centre. It is bright yellow.
We thought this looked like a good idea, better than the red bobbles or deep corderoy tactile surface in u.k.
We find that partly blind cannot see red blobs as easily as a yellow line
Also, those with walking and balance problems can be endangered by the red bobbles.
Wheelchair users with damaged spines find the bumpy ride over the bobbles cause pain.
So, does anyone know anything about this yellow groove system?
Is cycle ridge lower profile than bobble?
Is it available in a single or double ridge, rather than a wide multiridge band?
Is it available in a curve?
Could it be used to direct blind people to crossing points, but without endangering other disabled people?
Or, is the chinese system a completely different product?
In that case, does anyone have any detail?
At first, we thought it might be a single or double groove rather than a raised ridge. If so, would that work better?
We are thinking of
a) groove gets blocked with junk or ice but doesn't throw wobbly walkers off balance, nor hurt bad back people in wheelchairs
b) raised ridge is a problem for both groups, (though not as bad as those red bobbles,) but would it, too, collect junk and ice?
c) that bright yellow line looked good because for people with very little sight, it would guide them along the centre of the pavement, which would be safer than the outside edge, which is where blind and part blind people walk in uk. It would also show clearly where the route down the pavement reached a point to cross, with no need for bobbles there either.
