This weekend, 451 Washington State Department of Transportation (WSDOT) maintenance crews plan to install 1875 Astucia SolarLite solar-powered road studs as part of a test project on the centerline of a stretch of SR 530 which has a history of run-off-the-road collisions. Depending on the results of the tests and available funding, WSDOT says it will consider investing in additional test areas on other roadway surfaces or situations.

The solar-powered LED road reflectors, from UK-headquartered Astucia, part of the 557 Clearview Traffic Group, automatically illuminate from dusk to dawn to provide ten times greater visibility for drivers than traditional retro-reflective studs which are limited by the vehicle’s headlight beam.

“We often hear from drivers who are concerned about visibility in rain and snow,” said Dave McCormick, WSDOT assistant regional administrator for maintenance and operations. “We’re excited to test this cutting-edge technology to see whether it helps improve visibility and safety for drivers. If we get good results, we will look into using the reflectors on future safety projects.”

    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.

    Solar studs receive DfT approval
    Rennicks UK has achieved full Department for Transport (DfT) Type Approval for their SR-15 active road studs, which use LED and solar technology to create highly effective highway delineation said to be far more effective than traditional retro-reflective studs. The DfT authorisation, which follows a year-long trial, is likely to have far-reaching implications in both Britain and further afield, opening the door for local authorities and management contractors searching for cost-effective and sustainable
