Traffic island

It can also be a narrow strip of island between roads that intersect at an acute angle.

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.

[4] In certain areas of the United Kingdom, particularly in The Midlands, the term island is often used as a synonym for roundabout.
