VTT launches AV for snow and ice conditions, Finland

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 in which 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. They will be available in spring 2018.

    The RAINVISION project, co-financed by the European Commission, recently held its final meeting. Over the past three years, the project has researched the impact of road markings on driver behaviour under different night weather conditions (dry, wet and wet and rainy) and has assessed how different age groups and gender groups adapt their driving based on the above mentioned conditions. The results of the project were presented and in particular, the outcomes of three different trials conducted over the pro
