Effective delineation can deliver improved safety across our networks. From the centre or at the edges of carriageways to junctions, roundabouts, cycleways, footpaths and level crossings.
The use of active road studs can influence the way people drive by improving alignment awareness and understanding of road width – helping their driving position on the road – keeping them centred. TRL Research shows that both intelligent and active road studs have a significant positive effect on driver confidence where installed. This increase in confidence appears to be mainly due to an improved preview time of the road ahead, combined with assisting mitigation of the detrimental effects of glare from oncoming vehicles. Some believe that with confidence comes higher speeds, however the TRL research has also shown this not to be the case, the road studs themselves give a feeling of traveling faster when this is not actually the case.
More recently, studies have been carried out to look at using road studs as an alternative to street lighting. The study, Active Road Studs as an Alternative to Lighting on Rural Roads: Driver Safety Perception by Transport Research Institute at Edinburgh Napier University found that whilst demand for street lighting may remain, active road studs have a significant positive effect on driver confidence where installed, especially at night. Active road studs can prove extremely useful in rural areas, where power is a challenge and the environmental impacts to flora and fauna must be considered.
Use of our intelligent road studs has proven to be useful on bends in the road network and at junctions to help drivers gain more appreciation for what was in front of them as they emerge, for example. These road studs are hardwired, and mains powered, meaning they can be switched on or off and configured to suit your needs.
One project example is Sheriffhall Roundabout on the A720 in Scotland. Here, actively controlled road studs are synchronised in coordination with the A720 traffic signals on the roundabout. With this system in place, as soon as the traffic signal on the entrance to the roundabout turns green, the studs immediately illuminate and guide drivers onto the appropriate lanes of the roundabout (see case study below for more details).
Road accidents are more common after dark – allowing drivers to see further ahead gives them more time to respond to potential hazards such as sharp bends or junctions.
Intelligent Road Studs
Everyone’s aim should be to reduce road accidents over the coming years. We know that road accidents are more common after dark. There are many reasons for this, but most can be overcome through enhanced delineation. Allowing drivers to see further ahead, means they have longer to respond to potential hazards such as sharp bends or junctions.
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.
