Zitek melts barriers to North American market

South Korean company Zitek is launching its heated LED traffic signal solution in the US and Canadian markets—meeting with distributors and DoTs while waiting for its ITE certification. It’s just in time, as climate change is creating more dangerous wintery weather across North America.


As state DoTs have switched from incandescent bulbs to LED traffic lights to save energy and maintenance costs, an unintended consequence has been that the low-wattage bulbs do not get hot enough to melt snow that accumulates on the signals.

Enter Zitek and its new LED traffic signal. Called MeltSmart, the signal includes an automatic heating element that kicks on as a photo-electric sensor detects coverage while a thermal sensor ensures the blockage isn’t caused by some other obstruction like pollen, litter or plant matter. The heating element raises the surface temperature of the lens in seconds and then automatically turns off when the snow melts.

“By providing drivers and pedestrians with clear visibility of the signals, MeltSmart greatly contributes to avoid traffic accidents and possible loss of life in snowy weather conditions,” said Soyoung Lee, the company’s CEO. “With the unique patented technology, Zitek strives to help protect lives and build safer roads worldwide.”

While DoTs will need to rip out and replace existing traffic signals with Zitek’s MeltSmart signals, Lee said that the additional cost—which runs about 15% more than existing signals—can be recouped through a reduction in traffic accidents, their response and fewer complaints. And with replacement cycles turning over every several years, she doesn’t see deployment as a major roadblock.

    The UK government has suggested that driverless cars could be on the roads by 2021. But designers and engineers are grappling with a number of difficult issues, muses Chris Hayhurst of MathWorks Earlier this year, the UK government made the bold statement that by 2021, driverless cars will be on the UK’s roads. But is this an achievable reality? Driverless technology already has its use cases on our roads, with levels of autonomy ranked on a scale. At one end of the spectrum, level 1 is defined by th

Respiratory and other potential health problems which stem from pollution in the world’s increasingly urbanised environments have been well publicised and governments are
