Kiwi Lights Go Global
Airliners pulling up to the terminal at Vancouver International Airport could soon be guided to their parking spots by a
road lighting system developed in New Zealand. Harding Electronic Systems, of Lower Hutt, is trialling its SmartStud
road marker guides in several parts of the world, project manager Michael Hunt says. "The trial at Vancouver could be
the springboard to having the system installed at 19 other airports," Mr Hunt says. "Flashing lights in the studs,
instead of controllers with coloured wands waving their arms, guide the aircraft to their park on the apron." The
project to develop the stud was supported funding from Technology New Zealand, the Government agency that invests in
businesses to undertake research into new products, processes or services. The hardened plastic saucer-shaped studs were
designed to improve safety on roads, pedestrian and railway crossings by keeping drivers' attention on the road. The new
SmartStud is an advance on earlier versions. "The chief difference from the earlier stud is that they are powered
inductively - they're not wired up to a power cable," Mr Hunt says. "Power is supplied across the air and is picked up
by electronics inside the stud." The inductive technology was developed and patented some years ago by Uniservices, the
University of Auckland's commercial research arm. Mr Hunt says the new dome shape is a marketing point to make it
distinctive and practical. "I designed it so that a tyre hitting it would have minimal impact." The stud is made of a
new polycarbonate plastic shell developed by Bayer Plastics, which, he says, is tougher than the materials used on older
versions of stud road markers. They can be glued to bitumen roads such as in New Zealand, or the concrete highways of
North America. He says the benefits of the studs to road and airport authorities, motorists and pedestrians include ease
of installation. A small groove is cut in the road, meaning the road doesn't have to be dug up for cable to be laid. The
stud has a small generator that can be battery or solar-powered, and the bright LED lights can be seen up to 500 metres
away and from two directions. The mouldings are made in Wanganui and the electronics in Upper Hutt. Mr Hunt says that
CalTrans, the California highway authority, is conducting trials with the studs to see if they can withstand up to
220,000 impacts a day. As well, Transport Canada is set to test the studs in five kilometres of tunnels for luminosity.
Hardings has had interest shown from Malaysian toll-road authorities in Kuala Lumpur, and from Australia and China, and
has signed partnerships for distribution in Europe. -ends-
