Zebra print engines are the work horses that power your print and apply applications. Designed to be integrated into a high speed, high throughput packaging or shipping solution, these barcode label printers set the standard for reliable operation in any environment.
Connecting the cranks to the motor is a fairly standard-issue at this price point mixed Shimano 7-speed drivetrain made of a Tourney shifter and Altus rear derailleur. While the shifting performance is good, one of our major gripes about the Zebra lies in its drivetrain.
To get a feel for how the Zebra performs in each of its five PAS levels, we did put it to the test on our Electric Bike Report test circuit, where it performed well. We saw an average top speed around our one mile circuit of 21.8 mph and each of the five PAS levels yielded a nice and consistent change of speed ranging from 2 mph to 2.5 mph. This is in contrast to the Himiway Cobra we reviewed not long ago, which had almost no discernable difference in PAS levels.
In the PAS 5 test, the Zebra cleared the top of Hell Hole in a scorching 1:08.00 with an average speed of 16 mph, a time good enough for seventh place on the leaderboard. Using just the throttle, the Zebra powered up the hill in 1:19.00 with an average speed of 13.7 mph, which was good for eighth place on the throttle only leaderboard.
A zebra crossing (British English) or a marked crosswalk (American English) is a pedestrian crossing marked with white stripes (zebra markings). Normally, pedestrians are afforded precedence over vehicular traffic, although the significance of the markings may vary by jurisdiction. They are known as "zebra" crossings as the stripes resemble the coat of a zebra.
The first zebra crossing was installed in Slough, United Kingdom in 1951 to enhance pedestrian safety at new and already existing crossing points. Since then, zebra markings have been used at crossing points internationally to denote pedestrian crossings. Many have been replaced by various types of signalled crossing due to safety concerns.
Terminology and usage of the markings varies by country. In the UK and other Commonwealth countries, they are usually called zebra crossings, as the stripes resemble the striped coat of a zebra. In the UK, zebra markings are only found at unsignalised, standalone zebra crossings and must be accompanied with upright belisha beacons. In the US, they can be found at any type of crossing.
The origin of the zebra title is debated. 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. On being shown a black and white design, Callaghan is said to have remarked that it resembled a zebra. Callaghan did not himself claim authorship of the term.
The first zebra crossing was introduced on Slough High Street in the United Kingdom on 31 October 1951. Pedestrian crossings with Belisha beacons had been in use in the UK since the 1930s, originally introduced under Section 18 of the Road Traffic Act, 1934. The Belisha beacon is an upright crossing marking, still required by zebra and parallel crossings in the UK, named after the Minister of Transport in 1934, Leslie Hore-Belisha.
However, with an increase of car traffic, the effectiveness of the beacons was waning; both pedestrians and drivers were ignoring the crossing. From 1949 to 1951, the then-named Ministry of Transport experimented with designs to improve visibility and increase usage, until the familiar black and white stripes were introduced. The zebra crossing was then trialed at 1,000 experimental sites across the UK at this time. The zebra markings are credited to physicist and traffic engineer George Charlesworth, who was the first head of the traffic section at the Road Research Laboratory.
Sometimes, zebra crossings are placed on a speed bump, meaning the zebra crossing is level with the pavement. This is done to make it safer for pedestrians to cross, since drivers need to slow down to go over the speed bump. However, this is more expensive than a traditional zebra crossing, and can impede the flow of traffic and response times for emergency vehicles, especially on roads with higher speed limits.
The lines of a zebra crossing are commonly laid down by a road marking machine. Because the width of crossing lines is wider than other traffic lines, the marking shoe of a zebra cross marking machine is accordingly wider. The machine is hand pushed.
In the United Kingdom, it is the law that all road users, including motorists, give way to pedestrians who have set foot on a zebra crossing. A fine of £100 and three licence penalty points is given to those failing to give way at the crossings. This penalty has attracted criticisms of leniency when compared to other countries which enforce fines of up to £2,000. For failing to give way at a zebra crossing patrolled by a school crossing patrol ("lollipop man/lady" as they are commonly called), however, the penalty rises to £1,000 and a minimum of three licence points, with the possibility even of disqualification. In the United Kingdom, motorists have to stop for a crossing patrol, even when it is not on a pedestrian crossing.
In the United Kingdom, lollipop men or women (school crossing patrols) frequently attend zebra crossings near schools, at the hours when schoolchildren arrive and leave. Their widely used nickname arose because of the warning sign they hold up as they stop traffic: the sign is a large round disc on a long pole and thus resembles a giant lollipop, although they were originally of a square design.
Although zebra crossings exist in the US, the term is used to describe a type of diagonal crosswalk with two parallel lines painted over the stripes, similar but not identical to the ladder style. Instead, zebra crossings are called "continental crosswalks" and are the preferred style in many states because of its enhanced visibility compared to the other marking styles. In most areas of Canada, standard parallel lines markings are the preferred crosswalk style, except in Toronto where zebra markings are widely used.
In New Zealand, motorists are required to give way to pedestrians. Pedestrians wishing to cross the road within 20 m (66 ft) of a crossing facility (which includes zebra crossings) must use a crossing facility.
A 1998 Swedish study by A Várhelyi at Lund University found that the frequency of giving way at zebra crossings was 5% and drivers typically did not observe the law concerning speed behaviour at the zebra crossing. Speed behaviour in encounters (148 observations), non-encounters with pedestrian presence (642 observations) and situations without pedestrian presence (690 observations) were compared.
Three out of four drivers maintained the same speed or accelerated and only one out of four slowed down or braked. The study concluded that encounters between cars and pedestrians at the zebra crossing were critical situations in which the driver had to be influenced before he reached the decision zone at 50 to 80 m (160 to 260 ft) before the zebra crossing, in order to prevent "signalling by speed" behaviour.
The city of A Coruña in Galicia, Spain, has opted for spots rather than stripes at a pedestrian crossing, resembling a cow instead of a zebra. The reason for this option is to recognise the importance of the animal for the region's farming.
A number of countries have experimented with "three-dimensional" zebra crossings based on an optical illusion. The white stripes of the crossing appear to hover above the ground as though they were a physical barrier. Although intended to improve pedestrian safety on the crossings, they have also been popular with tourists who like to be photographed crossing them, appearing to hover above the ground. Such crossings can be found in Australia, Iceland, Malaysia, India, New Zealand and the United States.
A zebra crossing immediately outside the Russian Embassy in Helsinki was painted in summer 2013 with the colours of the rainbow to protest the Russian government's policy towards lesbian and gay people, the rainbow being one symbol of the LGBT culture.
A zebra crossing appears on the cover of The Beatles' Abbey Road album. The cover made the crossing a tourist attraction, and it has been incorporated into the Abbey Road Studios logo. Since the Abbey Road photo was taken, zigzag lines at the kerb and in the centre of the road have been added to all zebra crossings. English Heritage has given this crossing Grade II listed building status.
There is also a tongue-in-cheek reference to zebra crossings in the science-fiction comedy The Hitchhiker's Guide to the Galaxy by English author Douglas Adams, in reference to Man using the improbable creature called the Babel fish as proof of the non-existence of God; the novel says, "Man then goes on to prove that black is white and gets himself killed at the next zebra crossing."
As for class 3 e-bike, in addition to higher physical requirements for riders, compared to class 1 and 2, their price is certain to be higher. And the government has more rules for class 3 e-bike, many regular bicycle lanes and sidewalks are off-limits. If you are pursuing a higher speed and have a sufficient budget, an electric bicycle in class 3 will be more suitable for you.
A Spanish-style pedestrian crossing, also called a zebra crossing, dissected the route within the closing kilometer after the bunch roared toward the line carrying top speed. The safety feature designed to allow pedestrians to cross a roadway in a marked location is raised about six to eight inches above the pavement and are usually about five to six feet across.
There was a safety marshal waving a warning flag to warn the peloton, but speeds were nearing 60kph as the bunch barreled toward the finish line in what will likely be the only pure bunch sprint in the five-day race across northern Spain. 2b1af7f3a8
