Solar-powered LED road markers could light future roadways
Night-time travel is a necessary part of the busy world in which we live, but due to decreased visibility, traveling in the dark can be dangerous. The British have shed some light on night driving with the invention of the Astucia SolarLite flush road stud. The stud emits LED light, which is powered by small solar panels. The new stud tech is present on 120 British roads, and night-time accidents are down a dramatic 70% since the devices were installed. Amazingly, the SolarLite road stud gives drivers 900 meters of visibility, which increases reaction times to over 30 seconds. Reaction time with standard reflector studs is just 3.2 seconds.
With thousands of Americans dying on night roads every year, any incremental price vs. reflector studs would likely be a drop in the bucket when compared to the incredible savings in insurance claims alone. The government mandates billions of dollars in safety equipment on our cars and trucks, and both the automakers and customers foot the bill in the name of safety. If the SolarLite road stud is nearly as effective as it claims, the governments incorporating them could effectively reduce the likelihood that many automotive safety features would never need to be deployed.

BRITISH INVENTION SHOWS WAY AHEAD IN NIGHT-TIME DRIVING
Astucia SolarLite flush road stud uses stored solar power to give a ten-fold improvement in night time road visibility.
Shorter days and longer hours of darkness, along with inclement winter weather place particular emphasis on the need for road delineation, to show the driver where the road goes next. The latest generation of a British-designed "smart" road-stud has just been certified by the Department for Transport and is making a significant improvement to driving safety, with a big boost in visibility compared with the traditional reflective "cats-eye."
The Astucia SolarLite™ stud stores solar energy during the day, then built-in Light Emitting Diodes automatically illuminate from dusk to dawn, providing drivers with up to 900 metres of visibility. This is ten times greater than the traditional, retro-reflective, passive road stud which relies on being illuminated by the headlight beam of the approaching vehicle. At best it has a useful range of 90 metres.
The increased visibility given by the SolarLite road stud extends driver reaction times from 3.2 to over 30 seconds, when driving at 60mph. The studs are now in use in approximately 120 locations across the UK and a number of Local Authorities have reported reductions in night time accidents of well over 70% since the installation of the SolarLite "smart" road studs.
Research carried out by the Transport Research Laboratory also shows that when the smart studs are used, drivers also significantly less likely to cross the white line in the centre of a road or move out of lane on a dual carriageway. They also brake earlier and more consistently.
The greater number of visual references also means that drivers tend not to speed into the corners. In addition, the flush fitting studs are also safer for cyclist and motorcyclists. All make their contribution to added driving safety.
The latest generation of the SolarLite F Series intelligent road stud has taken advantage of improved solar panel and Light Emitting Diode (LED) technology, along with internal design developments, to allow costs to be dramatically reduced in comparison with earlier units.
The latest Astucia stud reduces casualties on the road and has a projected life of eight to ten years, compared with just one to two years for a conventional retro-reflective stud. Over its lifespan an Astucia "smart" stud will therefore cost no more than a traditional cat's eye. The units' efficiency can also allow a reduction in the use of energy- and maintenance-intensive, carbon-inefficient, streetlights.
In comparison with the cost and trauma of a fatal road accident of course, the price of any road stud fades into insignificance. According to the latest UK Department for Transport annual statistics, there are on average more than 8 fatal accidents every day, each one costing the country £1.69 million pounds. While only one third of all journeys occur at night, almost half of the serious or fatal accidents occur during the hours of darkness.
In the UK, Astucia road studs are currently installed on roads in Lothian in Scotland, the Vale of Glamorgan in Wales, in Buckinghamshire, Norfolk and Oxfordshire. They are also used in more specialised applications such as demarking cycle lanes in Cambridgeshire and Fast Track bus lanes in Essex.
The smart, safe and sustainable concept that created the Astucia SolarLite studs was conceived in 1989 by Martin Dicks. A former member of the London Fire Brigade, he formed Astucia to develop and market his invention in 1992..
Martin is recognised within the industry as one of the true visionaries in this vital field of road safety, building on the legacy of Percy Shaw, the inventor of the original "cats-eye" in the 1930s. Dicks is the inventor of an entire product range covering solar and hardwired studs, including studs that can warn of impending hazards such as fog, ice and surface water, or stationary traffic ahead
In 2003, Astucia made a significant step forward when John Madejski OBE DL, best known for his ownership of Reading Football Club and, more recently for his charitable work in the arts field supporting the Royal Academy and the V&A museum, acquired a controlling interest in the business. He made further investments to fund the R&D program and has supported the development of the company as a part of the Clearview Traffic Group, which also includes Golden River Traffic, a leader in the field of automated traffic counting and classifying, and Count On Us, the largest UK provider of transportation data collection and analysis services.
"Astucia is shaping the future of traffic safety by providing superior information to drivers about potential hazards direct from the road in their natural field of vision" says Martin Rodgers, sales and marketing director for Clearview Traffic. "The advance information on the road ahead provided to drivers by the Astucia studs is clearly proven to reduce incidents, so we're delighted to be able to bring to the market this next generation of flush stud, which is also easier and therefore cheaper to install, further justifying a unique British product which is continuing to prevent accidents and save lives."
