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.

    David Crawford welcomes new US guidance on public-private partnerships in the public transit sector. Public-private partnerships (P3s) are becoming increasingly favoured as a means of cost-effectively delivering much-needed public transit projects across the US. Previously, researched examples have tended to be on the large-scale while information on the potential for smaller, more localised schemes has been comparatively sparse. In a bid to fill that gap, the ‘Public Transportation Guidebook for Small

Just over a year after switch-on and with two global awards under its belt, the longest solar-powered toll road in the US is generating heightened interest in highway applications of alternative energy. The E-407, which loops around the eastern perimeter of the Denver metropolitan area in Colorado, won the International Bridge, Tunnel and Turnpike Association (IBTTA) President’s Overall Award for Excellence at its September 2013 Annual Meeting in
