Beware! Cats in the road

Smart cats' eyes to make roads safer

The humble cat's eye, invented in 1934, is to undergo a major high-tech overhaul.
First introduced on Britain's roads by Jim Callaghan in 1947 when he was a junior transport minister, the cat's eye is to become an "intelligent road stud" that will do a lot more than just help motorists follow the road at night.
The studs get brighter as visibility worsens and can be made to flash at the flick of a switch.
They can alert drivers to ice by turning blue when the road temperature drops below freezing and warn them of delays ahead by being switched to red or flashing amber.
The test studs on the M8 are connected to the national grid, but trials of solar-powered studs, which are not as bright, have been taking place in other areas, including Peterborough and the Vale of Glamorgan.
