Retroreflective sheeting is flexible retroreflective material primarily used to increase the nighttime conspicuity of traffic signs , high-visibility clothing , and other items so they are safely and effectively visible in the light of an approaching driver's headlamps . They are also used as a material to increase the scanning range of barcodes in factory settings. The sheeting consists of retroreflective glass beads, microprisms, or encapsulated lenses sealed onto a fabric or plastic substrate. Many different colors and degrees of reflection intensity are provided by numerous manufacturers for various applications. As with any retroreflector, sheeting glows brightly when there is a small angle between the observer's eye and the light source directed toward the sheeting but appears nonreflective when viewed from other directions.
44-633: Retroreflective sheeting is widely used in a variety of applications today, after early widespread use on road signs in the 1960s. High-visibility clothing frequently combines retroreflective sheeting with fluorescent fabrics in order to significantly increase the wearer's visibility from a distance, which in turn reduces the risk of traffic-related accidents. Such clothing is commonly worn as (often mandatory) PPE by professionals who work near road traffic or heavy machinery , often at night or in low-visibility weather conditions, such as construction workers , road workers and emergency service personnel. It

In 1999, the European Commission conducted the MAIDS report , comparable in scale to the Hurt Report, following Organisation for Economic Co-operation and Development (OECD) standards, and studying 921 accidents as well as exposure data on an additional 923 cases from five locations in France, Germany, Netherlands, Spain and Italy. In 2005, Congress passed

As a result, it is often worn in occupations where hazardous situations are created by moving vehicles or low lighting conditions. These occupations include railway and road workers, airport workers and emergency services. Cyclists and motorcyclists may also use high-visibility clothing to increase their visibility when operating amongst motor traffic. Hunters may be required to wear designated high-visibility clothing to prevent accidental shooting. The Hurt Report in

Hunting laws in each state or province may require hunters to wear designated garments in blaze orange to prevent misidentification of humans as game animals, and resulting shooting accidents. The required total visible area and times of use vary by jurisdiction and by
220-463: A significant improvement on black clothing at night and that retro-reflective strips were more effective when attached to knees and ankles than on a more or less static jacket. A 2012 British case-control study showed a non-significant increase in the odds of a crash for users of reflective conspicuity aids whilst cycling. In 2014, a further case-control study conducted in Canada reported a decrease in
264-403: A similar effect on driver perceptions. At that time there were no studies published that had actually demonstrated a reduction in collision crashes for bicyclists wearing fluorescent or retroreflective clothing whilst on public roads. A 2009 Australian study of drivers trying to see stationary cyclists on a closed circuit found that fluorescent vests (without retro-reflective stripes) were not

At the time, the funding was still about $ 2 million short. The National Transportation Safety Board originally had recommended a scope of 900 to 1,200 case studies. In 2009, the Federal Highway Administration and Oklahoma State University 's Oklahoma Transportation Center began conducting an 'abbreviated' Motorcycle Crash Causation Study with 300 case studies "to help identify common factors – including road configurations, environmental conditions and rider experience" and "how these factors may be affected by countermeasures that, if effectively implemented, will prevent motorcycle crashes or lessen

#1732790712761968-714: The current state of motorcycle safety: The more time goes by, the less things look different. Riders today have the same sort of accidents as riders in the 1970s, except that today they crash much more expensive bikes. Between 1997 and 2008, motorcycle rider annual fatalities increased from 2,116 to 5,290 – a 150 percent jump, according to U.S. Department of Transportation's Fatality Analysis Reporting System. In 2008 alone, deaths due to motorcycle crashes rose by an estimated 2.2 percent while all other vehicle classes saw reductions in fatalities. — Oklahoma State University, Transportation Center , 2009 In David Hough 's book Proficient Motorcycling , Dr. Hurt said he had always assumed
1012-430: The effectiveness of visibility aids (fluorescent and retroreflective clothing and equipment) was carried out by Kwan and Mapstone in 2006. The authors found 42 studies which collectively suggested that fluorescent clothing could increase the distance at which drivers could detect and then recognise cyclists in daylight conditions. The same review found evidence that retro-reflective materials worn by cyclists at night had

Consistent with its stated provisions, the Motorcycle Safety Foundation withdrew support of the abbreviated study, saying such a study would be "unlikely to either validate the findings of prior studies or establish, to any statistical significant level, any new causative factors. The abbreviated study would be unlikely to accomplish either of these goals because the sample size
1100-414: The motorcycle and rider." A New Zealand case-control study found that the population attributable risks were 33% for wearing no reflective or fluorescent clothing; one third of motorbike accidents might have been prevented by wearing high-visibility clothing. Conspicuous behaviors, such as the wearing of high-visibility clothing, the use of headlights in the daytime, and the use of a white helmet, reduced

The study took place throughout the City of Los Angeles including urban as well as rural conditions, e.g., incidents of motorcycles striking animals. Each accident was studied individually with approximately 1,000 data elements, collected for each of the 900 accident scenes, including measuring and photographing vehicle damage, skid marks, scrape marks, people marks, and interviewing survivors. Hundreds of accident-involved riders donated their helmet to

1408-639: The risk of a rider facing a collision. Traffic risks to the cyclist are similar to those faced by motorcyclists, with the main differences being that cyclist speeds are typically lower, and the cyclist wears less protective gear. In a 2009 study, most UK cyclists and almost all motorists believed that high-visibility clothing would increase cyclists' visibility. Almost all drivers agreed that cyclists need to wear reflective clothing in low lighting environments, whereas less than three-quarters of cyclists (72%) agreed, and less than half claimed that they always did so. A Cochrane Systematic Review of research evidence for
