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.”

    A study has shown the extent and ramifications of wrong way driving and proposed cost-effective countermeasures. Wrong way driving collisions occur relatively infrequently but the results can be devastating. Statistics from the US National Transportation Safety Board, an independent, federal all-modes agency, reveal that wrong way (WW) driving, account for only about 3% of accidents on high-speed divided highways but are much more likely to result in fatal and serious injuries.

    A US pooled fund study group has developed a system of software aimed at taking the concept of winter maintenance decision support to a new level – a scientific ‘one-stop-shop’ of weather and service performance data. This report is by Charles Chambers and Benjamin Hershey. With advancements in environmental technology come new systems that assist agencies with better management of winter roadway maintenance resources. In the late 1990s the US Federal Highway Administration (FHWA) began work developing a pr

    The technical programme of this year’s ITS World Congress in Vienna includes a special session on the image of enforcement. ITS International examines the scale of the problem and what can be done about it. Debate on the merits and difficulties of enforcing speed limits appears centred on a conflict of principles. Put very simply, local communities, people living close to busy or hazardous roads, want to see traffic speeds calmed. Drivers on those roads, on the whole, want their principle of freedom to be m
