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
A zebra crossing in Singapore. Two flashing Belisha Beacon are positioned, one on each side of the road, at a zebra crossing, which flashes from 7 pm to 7 am daily, indicating to an approaching motorist of a zebra crossing. Older crossings display the blue square zebra crossing signs on both sides (see above), which are synonymous to the ...
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 British zebra crossing. The British Government's Road Research Laboratory's (RRL) Traffic and Safety Division was established at Langley, near Slough in 1946. [1]: 2 The division was soon tasked with developing a new type of pedestrian crossing that would be visible in all weather conditions. [2]
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 ...
Research undertaken in New Zealand showed that a zebra crossing without other safety features on average increases pedestrian crashes by 28% compared to a location without crossings. However, if combined with (placed on top of) a speed table, zebra crossings were found to reduce pedestrian crashes by 80%. [110]
One of the world's most heavily used pedestrian scrambles, the Shibuya Crossing at Hachikō Square in Tokyo. A pedestrian scramble (or exclusive pedestrian interval) is a type of traffic signal movement that temporarily stops all vehicular traffic, thereby allowing pedestrians to cross an intersection in every direction, including diagonally, at the same time.
