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.”
