Page "Pedestrian crossing" Paragraph 12

Pedestrian refuges or small islands in the middle of a street may be added when a street is very wide, as these crossings can be too long for some individuals to cross in one cycle.

In places where there is very high pedestrian traffic, pedestrian scrambles ( also known as Barnes Dances ) may be used, which stop vehicular traffic in all directions at the same time.

Another relatively widespread variation is the Curb ( or kerb ) extension ( also known as a bulb-out ) which narrows the width of the street and is used in combination with crosswalk markings.
