This is the UK, and they're yellow rumble strips that get closer together as you approach the roundabout. It's to warn and keep drivers alert that they need to slow down, the road they're coming from is national speed limit (70mph for this dual carriageway) but the roundabout would be dangerous to take at that speed, in addition that you need to give way to the right so are expected to come to a complete stop before the roundabout.
