SR-i19 solar stud: visible up to 1km away

Sernis has launched two solar road studs: SR-i19 and SR-i25.

They use microcontroller technology, and only rise 9mm and 10mm respectively from the road surface: the company says they are "ideal for road delineation, bends/curves, and crosswalks among other applications".

They have constant brightness during all functioning periods and can be seen up to 1km away.

SR-i19 has a high light output due to its 3 LEDs for each side, with an aluminum base giving it strong mechanical resistance.

SR-i25 has a stainless-steel cap that makes it ready for snowploughs, while built-in GPS technology allows flashing synchronisation. It is also available in aluminum.

Sernis highlights its high-performance photovoltaic solar module, with silicone-free junction sealing technology allowing better, faster, and cleaner maintenance.

The technology applied to both models "increases the performance of solar power studs with energy storage by battery or capacitors and protects the road stud against the deep discharge of the batteries/capacitors", Sernis insists. 

'Sleep' mode prevents discharge during storage or transport, and the manufacturer points to their ease of installation and the fact that the studs require "virtually no maintenance".

    Solar-powered traffic detection improves communication
    Pete Goldin reports on a new wireless, solar-powered traffic detection system being used by Caltrans District 12. As more and more traffic data is necessary to satisfy the needs of traffic management centres and traveller information systems, and as traffic detection technology becomes more ubiquitous, transportation authorities are pressured to find more economical ways of expanding their detection systems. Caltrans District 12 is leading this push by deploying the latest detection system from Case Global

    Rethink required to reduce road transport’s environmental impact
    Against a background of a renewed focus on limiting the rise in average temperatures, Colin Sowman looks at a project that is taking a holistic approach to the environmental impact and safety of road transport. At the COP21 meeting in Paris last December, almost 200 nations agreed to reduce greenhouse gas emissions in an effort to keep the rise in global temperatures to 2°C) compared with pre-industrial levels. The transportation sector is a major contributor to the production of CO2, one of the main green
