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.”

    A planned Washington Department of Transportation (WSDOT) study could make tolling on interstate-90 bridges over Lake Washington and across Mercer Island all but inevitable. Tolling on the state route 520 floating bridge began about a year ago and transportation officials have been closely monitoring two factors: the routes that drivers are now using and the cost to replace the aging 520 bridge. In response, the state legislature last session asked for a new environmental study to review the affects of toll

    Sernis lights the way with road studs for harsh conditions
    Portuguese manufacturer Sernis has introduced the SR-40, a reflective road stud that is very much at home in harsh conditions and is snowplough-resistant. Its design includes a solar panel of less than 1W in power, making it perfect for countries with low sun exposure. The stud also has RF low power 868MHz mesh network communication and has microcontroller technology inside each stud. Features include a wake up and sleep function, automatic brightness control and night-level contraction.
