Washington State testing Astucia SolarLite road studs

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.”

    The UK government has suggested that driverless cars could be on the roads by 2021. But designers and engineers are grappling with a number of difficult issues, muses Chris Hayhurst of MathWorks Earlier this year, the UK government made the bold statement that by 2021, driverless cars will be on the UK’s roads. But is this an achievable reality? Driverless technology already has its use cases on our roads, with levels of autonomy ranked on a scale. At one end of the spectrum, level 1 is defined by th

    A common assumption, even amongst informed observers, is that there’s but a handful of urban charging schemes in operation around the world and scant prospect of that changing any time soon. Larger city-sized schemes such as Singapore, London and Stockholm come readily to mind but if we take a wider view and also consider urban access control and Low Emission Zones (LEZs) then the picture changes rather radically. There is a notable concentration of such schemes in Europe but worldwide the number is comfort

High-tech solutions like GPS guidance systems and low-tech products like potato juice are helping states to cut costs, improve efficiency, and minimise environmental impacts. The Alaska Department of Transportation and Public Facilities uses a variety of advanced technologies to combat extreme winter weather and
