Clearview releases new solar stud to improve highway safety

Clearview Intelligence, Zeta Specialist Lighting and AEV have produced a solar-powered road stud designed to reduce night-time road accidents by improving guidance and hazard warnings to night-time drivers. Called SolarLite 2 (SL2) the stud is said to provide visibility of the road geometry up to 900m ahead - a 10 fold increase over reflective studs - and to decrease night- time accidents by over 70%. It uses solar powered high intensity LEDs, which do not rely on vehicle headlights to perform effectively.

Clearview Intelligence, Zeta Specialist Lighting and AEV have produced a solar-powered road stud designed to reduce night-time road accidents by improving guidance and hazard warnings to night-time drivers.

Called SolarLite 2 (SL2) the stud is said to  provide visibility of the road geometry up to 900m ahead - a 10 fold increase over reflective studs - and to decrease night- time accidents by over 70%. It uses solar powered high intensity LEDs, which do not rely on vehicle headlights to perform effectively.

The increased distance visibility allows drivers additional reaction time to respond to road layouts ahead. At a vehicle speed of 100km/h (62 mph), this can increase the time a driver has to react from 3.2 seconds to over 30 seconds.

SL2’s road studs use patented solar energy harvesting and storage electronics to power high-intensity LEDs. The robust housing of the embedded road stud has a profile of less than 4mm above the road surface, making them unobtrusive to road users, and able to withstand passing traffic and snowplough use. It will be available in Spring 2018.

    Refurbishing old dynamic message signs can save money and increase technical capabilities as David Crawford discovers. Evidence is growing on both sides of the Atlantic of the scope for retrofitting old or technically out-of-date dynamic message signs (DMS) with new electronic equipment, to save on the costs of installing full-scale replacements. In the last four months of 2014, a number of US states progressed programmes that achieved savings of more than US$1.75 million (€1.56million).

    Colin Sowman looks at some enforcement case studies from around the world. It is a sad fact of life that unenforced laws are not adhered to by a sometimes sizable proportion of the public and once enforcement is seen to be lacking, some drivers can take this to extremes and authorities must decide how to regain control.

The extent and quality of the visibility available to drivers is crucial in preventing and avoiding incidents. Conventionally, they have had to rely on fairly basic equipment - essentially the human
