Cats eyes road markers?
A long time ago I thought this was a good idea, with no budget or inclination to action it practically I put it up here for comment/critique
In the UK and many other countries the centre and edge of the road is marked with reflective dots. In the UK we call these cats eyes as the inventor was supposedly inspired by the way a cats eyes shine in the dark.
However good though they are they only reflect as far as your light beam reaches. On dipped beam this may not be that for ahead and with the sort of traffic we get in the UK you hardly every get to use the main beam.
My suggestion is to cut a slot down the middle of the road and lay in it a fibre optic cable linking every cats eye in groups of say 50 or 100.
The ides is as the diagram shows the Fibre optic carries your dipped head light far further then it would normally shine without the risk of dazzling other road users.
I think that this would significantly improve road safety at little cost if done when road refurbishment was carried out anyway as at this time the cats eyes are often removed and replaced. The cats eyes could be simpler, lower profile and possibly cheaper to makeas they would only need to be a plastic holder for the fibre.
