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.

    Traffex snapshot reveals enforcement advances
    An indication of just how far beyond spot speed and red light the enforcement sector has progressed was evident in the range of new and improved equipment on display at the recent Traffex event in Birmingham. One of the key trends, particularly in the UK but also evident elsewhere, is the increase in average speed enforcement, according to RedSpeed’s managing director Robert Ryan, who predicts a big increase in installations this year. “The price point has reached a level authorities can afford,” he says, a
