Cats Eye Cameras
Its True, and this is what they look like.
It sounds like the speeder's nightmare. A speed camera accurate
up to 150mph which can be concealed in a road stud as small as
a cat's eye.
It's being trailed in Scotland
The camera is just 130mm in diameter, and can protrude
from the surface by just 5mm; and it is linked to a computer that
can read and decode number plates written in both italic and cursive
The idea is that you would use it in the approach
to somewhere with a lower speed limit. The camera will look at
each oncoming vehicle and measure its speed. Then you'll have
illuminated road studs that will light up on the approach to a
pedestrian crossing, say, and a sign that could light up with
the number plate telling people to slow down.
The camera is a logical follow-on from Astucia's
self-lighting road studs, now being trailed in Hampshire. These
are intended to give motorists advance warning about traffic lights
they might be unable to see due to fog or high-sided vehicles
ahead. When the lights ahead were green, the studs would remain
dark. But as the lights turned amber, so do the studs, flashing
twice a second until the lights turn red. The studs marking the
lanes would also flash.
Used in the US, the studs are claimed to have reduced
accidents by 80 per cent. The tiny speed cameras would be the
next step on the road to safety, and the Scottish Office is testing
them in Motherwell.
The cats eyes are marked, look closely enough
and you can see the IR Glow from some. Even though the arrows
I have drawn don't go round the bend the cats eyes do.
