Reflective studs on motorway are safety devices used on roads. These devices are usually made of plastics, ceramics, thermoplastic coatings or occasionally metal, and come in a variety of shapes and colors. Reflective studs on motorway include lenses or reflective sheets, which enhance visibility by reflecting automobile headlights. Some other names for specific types of reflective studs include convex vibration lines, Botts' dots, contour lines, cat's eyes, road studs or road turtles. Sometimes they are simply referred to as "reflectors".

Red studs mark the left edge of the road. Amber studs mark the central reservation of a dual carriageway or motorway. Green studs mark the edge of the main carriageway at lay-bys and slip roads. Green/yellow studs indicate temporary adjustments to lane layouts, e.g. where road works are taking place.
Offering over 1,000m of sharp, defined delineation during the day and after dark, the IRS2 intelligent road studs are customisable, highly visible in-road lighting systems that increase lane discipline, reducing accidents and collisions at roundabouts, road intersections, crossings, crosswalks, bus interchanges, railway crossings and tunnels.
“The Intelligent Road Studs are a product we have used before, but not at a motorway to motorway junction and not in the north west region. Connecting the studs to the traffic signals is a first for Highways England and we’ve found this innovative use of them to be a very effective way of guiding drivers, helping them stay in the correct lane and so avoiding the risk of a collision.”
Sep 20, 2004 · Cables under the road surface connect them to traffic lights through a nearby automatic controller unit. The studs can be visible up to 1,000 metres away – far greater than traditional reflective road studs – and have been proven to help stop drivers drifting between lanes, reducing the risk of collisions.”
An intelligent transportation system (ITS) is an advanced application which aims to provide innovative services relating to different modes of transport and traffic management and enable users to be better informed and make safer, more coordinated, and ‘smarter’ use of transport networks.
The ‘Intelligent LED Road Stud’ is the evolution of the cat’s eye taking it from the simple reflective lane indicator to a powered light visible from a kilometre away, which can also be connected to other traffic systems and turned on and off to help direct traffic flow.
The aim of this project was the development of an intelligent LED road stud, with integrated communication and sensor systems, that is compatible with existing traffic management infrastructure
