In 2017 Highways England commissioned upgrade works to be undertaken on the A38, an ageing dual carriageway providing a major transport route through the Midlands. The condition of the road was poor; an ageing highway and localised surface defects had caused potholes, deep ruts and the white lining was heavily degraded. The geometry, lack of street lighting and short on-and-off slip roads contributed to poor visibility of the road layout ahead.
The challenge facing Highways England was to bring an older road up to modern standards without the ability to amend the layout, whilst minimising disruption to road users. The objective was to deliver a lasting, 20-year solution that would improve the road users’ experience, increase visibility for drivers and require minimal future maintenance to avoid disrupting the 23,000 motorists who use the road daily.
When compared to more modern road designs, the slip roads on the A38 had a smaller entrance point and were shorter in length whilst some of the bends were sharper. Unable to reconfigure the layout, Highways England had to find a solution that would provide enhanced delineation to give drivers the best view of the layout ahead without using street lighting.
Previously, retro-reflective road studs had been used for carriageway and slip road delineation. However, the performance of these had tended to degrade quickly, requiring regular upgrades and replacements. For Highways England, this meant visibility for drivers was often sub-standard, and the costs associated with replacing the degraded studs, combined with the disruption to the travelling public during the replacement work, was becoming a significant issue.
Highways England chose to upgrade from retro reflective road studs and install more than 5,000 of Clearview’s SolarLite Active Road Studs on both carriageways along a 10 kilometre stretch of the road. With an operational lifespan of up to eight years, the studs require less maintenance than retro-reflective road studs, reducing the frequency for future repairs and road closures and subsequently minimising disruption to drivers.
Red, amber and green studs were used to highlight the edge of carriageways and slip road entry/ exit points. White studs were installed along the centre of the road.
The SolarLite Active Road Studs store solar energy during the day and illuminate as darkness falls to provide effective year-round performance that does not deteriorate over time. Using powerful LED lights, the studs provide a view of the road ahead ten times further than that provided by traditional retro-reflective studs. This gives drivers ten times longer to react to changes in the topography.
The studs have a low profile of less than 4mm so do not present a hazard to motorcyclists and have been proved to reduce night-time accidents by more than 70 percent.
Combined with other improvements including some of the latest high visibility lane markings (that can be seen at night and in adverse weather conditions), delineation along the A38 has been enhanced.
We’re always looking for new ways to further improve journeys and safety for drivers and this is a great example of that. This section of carriageway has no street lighting, so the solar road studs and improved lane markings make a real difference. At the same time the new technology is more durable, meaning less disruption for motorists in the long term thanks to fewer roadworks.
Smart, safe and sustainable solar powered road studs, proven to increase night time road safety. Providing a view of the road layout ahead in the driver's natural line of vision and well beyond the headlight beam of a vehicle.
Three major 1st class routes were identified for route safety solutions by our local partner in Slovakia.
Cambridgeshire County Council, in partnership with Milestone Infrastructure decided that all studs should be fully renewed.
With SolarLite Road Studs installed for the illumination of stretches on the M25 Motorway and also between the M2 and M20, Clearview Intelligence installed a quantity of 7,000 Road Studs between junctions 3, 4, 5 and 6 on the M40 Motorway providing ultrabright guidance to motorists around the clock.
Intelligent Hardwired Bi-Directional Road Studs installed at Blackwall Tunnel in Kent to create a contra-flow from the southern boar to the northern boar.
SolarLite Active Road Studs trialled in Sweden to see if they can withstand impact from snow ploughs and cope in extreme cold weather

The Shoreham Road forms a U-shaped link road providing access to air-freight warehousing associated with the Airport. In context, the top of the ‘U’ is in the north, the east and west outer sides are warehouses which are used to transfer freight between ‘airside’ (cargo planes) and ‘landside’ (HGVs).
The A50 is a strategic east to west connection between the M6 and M1
The Stoneferry Corridor is a primary route originating north of Hull, with strategic connections to the Port of Hull, City Centre, and Eastern areas of Hull. It is heavily dominated by industry, HGV activity and businesses, with pockets of residential, retail, and educational buildings.
