Engineering:Traffic island
A traffic island is a solid or painted object in a road that channels traffic. It can also be a narrow strip of island between roads that intersect at an acute angle. If the island uses road markings only, without raised curbs or other physical obstructions, it is called a painted island or (especially in the UK) ghost island. Traffic islands can be used to reduce the speed of cars driving through,[1] or to provide a central refuge to pedestrians crossing the road.
When traffic islands are longer, they are instead called traffic medians, a strip in the middle of a road, serving the divider function over a much longer distance.[2]

Some traffic islands may serve as refuge islands for pedestrians.[3] Traffic islands are often used at partially blind intersections on back-streets to prevent cars from cutting a corner with potentially dangerous results, or to prevent some movements totally, for traffic safety or traffic calming reasons.[4]
In certain areas of the United Kingdom , particularly in The Midlands, the term island is often used as a synonym for roundabout.[5]
