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.

    The DRIVE C2X provides a comprehensive, Europe-wide assessment of cooperative systems through field operational tests, and is to present its results on 16 and 17 July in Berlin. The test results are the last step in the preparation for the roll-out of cooperative systems in Europe. During the three and a half years of the project, more than 750 drivers tested eight safety-related functions of cooperative functions all over Europe. The operational tests took place in seven test sites in Finland, France, G
