Recent Highways News coverage ‘visibility concerns’ – Highways News of RSMA research highlights a clear and growing challenge across the UK road network: over 20% of drivers avoid roads at night due to visibility concerns, with even higher figures among younger motorists.
While often framed as a behavioural trend, the implications extend further than route choice alone. When visibility is reduced, driver confidence changes and so does how the network is used. This includes reduced night-time travel, increased avoidance of rural routes, and wider impacts on accessibility and local connectivity.
Visibility is shaping behaviour
The RSMA findings reinforce a long-standing reality in highway safety: perception of the road is as important as the physical condition of the road itself.
Where edge definition, alignment cues and forward visibility are unclear, drivers adapt their behaviour accordingly, often by reducing speed or avoiding those environments entirely. In rural areas, this effect is amplified by lower lighting levels and longer stretches of unlit carriageway.
Beyond conventional delineation
Traditional road markings remain essential, but their performance is inherently dependent on external conditions such as lighting, weather, and wear.
In many rural environments, this challenge is further compounded by less frequent maintenance cycles and sections of carriageway where markings may be faded, intermittent, or in some cases absent altogether. This creates a natural variability in visibility that directly influences driver confidence and decision-making.
In low-light rural environments, this combination of environmental conditions and infrastructure variability creates a visibility gap, one that can lead to hesitation, reduced travel at night, or avoidance of certain routes altogether.
A role for enhanced delineation
This is where solar-powered, active visibility delineation systems such as SolarLite have been developed to support the network.
SolarLite road studs provide active, ground-level illumination to enhance edge definition and forward guidance in environments where conventional lighting is not practical or cost-effective. Unlike passive systems, they generate their own light, helping maintain consistent visibility in low-light and unlit conditions.
By operating independently of mains infrastructure, SolarLite is particularly suited to rural roads, junctions, bends, and remote stretches where maintaining reliable visual guidance is most challenging and where driver confidence is often most affected.
The result is improved road readability at night, stronger delineation of carriageway edges, and enhanced perception of alignment, supporting earlier, more confident driving decisions.
The intent is not to replace traditional markings, but to reinforce them – extending the visual clarity of the road in conditions where perception is most compromised.
