60th anniversary of the Zebra Crossing

The first Zebra Crossing was opened in Slough, Berkshire, on 31st October 1951

The sources below suggest that the Zebra may be phased out in favour of other more expensive signalised crossings.

Research by the New Zealand Transport Agency in 2007 suggested that a zebra without any traffic slowing measures could actually increase pedestrian accidents by 28%. Combined with a speed bump, however, it reduced them by 80%.
