Zebra crossings are so named because their stripes resemble those of a zebra, though the origins of the link are disputed. The origin of the zebra title is debated. [4] It is generally attributed to British MP James Callaghan who, in 1948, visited the country's Transport and Road Research Laboratory which was working on a new idea for safe pedestrian crossings.
A zebra crossing in Antrim. Zebra crossings are a type of controlled crossing indicated by white longitudinal bars across the carriageway and upright flashing globes, known as 'belisha' beacons. Zebra crossings can be used on roads where the 85th percentile speed is not above 35mph. The minimum width for a crossing is 2.4 m. [4]: 125
The other method involves the use of the more easily visible "continental stripes" (like the UK's zebra crossings), which are sets of multiple bars across the crosswalk itself that are perpendicular to the direction of crossing. These bars are typically 12 to 24 inches (300 to 610 mm) wide and are set 12 to 24 inches (300 to 610 mm) apart.
A Belisha beacon atop its striped pole. This example also features a spot lamp to illuminate the crossing at night. A Belisha beacon (/ b ə ˈ l iː ʃ ə /) is a yellow-coloured globe lamp atop a tall black and white striped pole, marking pedestrian crossings of roads in the United Kingdom, [1] Ireland, and other countries historically influenced by Britain, such as Hong Kong, Cyprus, Malta ...

[citation needed] In the United Kingdom and elsewhere, raised markers are used to mark pedestrian crossings to assist the blind in crossing streets. In colder climates, reflective markers may be installed below ground using an elongated narrow triangle, cut into the road surface that allows the device to be installed below the road surface.
