Driver fatigue
Studies conducted by the European Transport Safety Council highlight that fatigue contributes to approximately 10% to 20% of road crashes (Zheng Wang,). Similarly Horne and Reyner (1995) report that approximately 20% of worldwide motor vehicle accidents on motor-ways and other monotonous roads are caused by drivers falling asleep behind the wheel due to fatigue. However significant awareness must focus on the fact that fatigue causes problems for driving performance well before the driver actually falls asleep meaning that “one of the major challenges in addressing the impact of driving fatigue is the difficulty in detecting fatigue and issuing a warning, particularly when fatigue is likely to increase the incidence of crashes”

Zheng Wang (####) demonstrates that driver fatigue can be subcategorized into sleep-related and task-related fatigue. Such subdivision is dependent on various factors which significantly contribute to the driver’s fatigue state.
Task-related fatigue is caused be external factors which are not controlled by the operator. Both of these factors correlate to the driving task and the driving environment. Furthermore, task-related fatigue is subcategorized into active and passive fatigue. Active fatigue is dependent on an overload state of driving conditions, whereas passive fatigue is induced by under load conditions. Overload states may be caused by severe traffic conditions, extreme weather conditions as well as performing multiple tasks while driving. Under load conditions are the result of a monotony state such as an empty straight freeway as well as a plain and flat driving environment.

Kimura et al. (2008) conducted a statistical analysis on the Japan National railway correlating the quality of the trains with vibrations. The study was conducted over a variety of trains and journeys investigating the correlation between vertical vibration and the Ratio of Sleeping Passengers (RSP). Results highlighted that low frequency vibration between 0 and 2 Hz had a positive effect on sleepiness whereas vibrations between 10 and 20 Hz significantly reduce the RSP ratio descending train ride quality. Also the research supports the hypothesis that sleep induction technology may be used to cure insomnia patients or to aid sleepless parents of newborn babies. Yet such research lacks in providing an analysis on the effect of the amplitude of the vibration on a state of sleepiness or
Roads today can be very unsafe. A major cause of this is thr truckers that are fatigue and still working. Karen Levy goes into explaining how we can help eleviate this issue in her piece, "To Fight Trucker Fatigue, Focus on Economics, Not Electronics". Throughout her article she uses different strategies to persuade the reader on how we can go about eleviating the truckers of being so exhausted. Levy uses different tractics such as pathos, acknowledeges the unsafness of truckers working while fatigue and reasoning for truck drivers being excessively fatigued.
So what can happen if drivers are not totally focused? According to the National Highway Transportation and Safety Administration (NHTSA), almost 6,000 deaths, over 500,000
What is distracted driving? Distracted driving is any activity that could divert a person's attention away from the primary task of driving. All distractions endanger the driver, passengers, and bystander safety. I believe that it is extremely important to emphasize the dangers of distracted driving among all drivers, but most especially teenagers—in this age of new technology. I do think that many drivers are aware of the dangers of driving distracted, but it is also possible that they simply decide not to follow the rules.
Sleepless in American is a National Geographic documentary on the lack of sleep Americans are receiving each night. The film starts with the statistic that “40% of American adults are sleep deprived” and followed with different effects of sleep deprivation such as: weight gain, delayed reaction time, depression, anxiety, speeds the growth of cancer, and has been linked to Alzheimer’s disease. Although, there is no scientific evidence to support the need for sleep, it is an important process that allows our bodies to function properly. Several sleep studies have been performed to understand the effects sleep deprivation has on a person. The participants of the sleep trial only received four hours of sleep per night.
To prevent the danger of tired driving, drivers should get the sleep needed at night. Some people only sleep for six hours which is not enough, even for a grown adult. Studies have shown that a healthy adult requires seven to nine hours of sleep every day. People underestimate the dangers of fatigued driving, so a solution to this is that the government could address this dangerous activity to the public by educating them by using advertisements, or even a catchy billboard to remind drivers not to drive while tired. This could lessen many injuries and even deaths as people would not be falling asleep while driving so they would not
In a 2007 study " of 895 hospital staff nurses, 596 (66.6%) reported having driven while drowsy at least once during the 28-day study period, and 30 (3.4%) said they drove while drowsy following every shift they worked" (Eanes,
“Slow response time, loss of clarity in vision and hearing, loss of muscle strength and flexibility, drowsiness due to medications, and a reduction in the ability to focus or concentrate” are all effects of aging identified in Westport News’s March 2010 article “Should elderly drivers be retested?” 2. Although some older drivers try to make up for these disabilities by driving more cautious, driving below the speed limit can cause more dangers. B. Cause 2: The trend of increases in fatal accidents involving elderly people is partially due to an increased susceptibility to injury and medical complications within this age group. Transition 3: While car accidents involving the elderly is a widespread issue, there are multiple solutions that can be implemented to reduce the likelihood of this occurring.
Fatigue is also a major precondition for unsafe acts. In the case at hand, there was no recorded evidence from the CVR that either of the crew members was exhausted. However, from the yawn recorded, it appeared that either the captain or the first officer was fatigued. While it was not readily available to determine whether they were fatigued, through the post-accident interviews, it was mentioned that self-evaluation of fatigue or of another person by a fatigued person was not dependable.
The amount of students getting less than 7 hours of sleep every night went down by 97.4% from the time of the first survey to the second. Those who were receiving 8 or more hours a night increased all the way from 16.4% to 54.7% (Burke 37). Although the number of students reporting bad quality of sleep and short sleep duration decreased significantly from the first survey to the next, students still had difficulty falling asleep several times a week (Burke 37). The second survey also reported a decrease in fatigue, sleepiness during the day, and symptoms of depression. Most health-related issues and complaints such as class attendance and visits to the school 's nurse’s office also decreased from the first survey to the other (Burke
Introduction Attention Getter: Sleep is essential, especially around us college students who spend each night staying awake to do projects we should of started weeks ago. Purpose: Well, now you can have a good rested night with these new tips and tricks!
Nurses fatigue is growing problem nurse face each day in the healthcare environment, and he can be caused by long hours, sleep deprivation, and possibly by accepting extra assignments can be dangerous for both nurses and patient. These inadequacies can result in major implications for the health and safety of registered nurses and can compromise patient care which can lead to fatalities. (American Nurses Association, 2014). In my experience, being fatigued from working much 12-hour shifts consecutively was very difficult as I felt extremely tired, resulting in lack of focus, missing important details during the handing over the process with impaired cognitive functioning. This I found was detrimental to the patients and myself as it impedes quality and has a deleterious effect on patient safety.
Introduction Good morning everyone. I’m Nur Atiqah binti maznan and today I will deliver a speech title ‘People should care more about sleep’ Most of us in this class will say that we not get enough sleep because of all assignments, lab reports and so on like just now. So, we called this situation as sleep deprivation which means a condition where people not get enough sleep. We are in the same shoes, so no worries. A research from Brown University stated that, from a survey they conducted to a group of college student, 11% student have a good sleep but the rest which is 73% from the same study were found to have a sleep problem.
As it is apparent from this example, sleep is not my strong suit. However, this situation is not limited to just me. In fact, millions from across the nation go through the exact same process of tossing and turning to no avail every night. In consequence of this, the effects of such habits can be seen through society and our lives. It does not have
Not only are the long hours of sitting hard on truck drivers’ backs, but so are all their other tasks. It is easy to overlook the heavy toll that securing loads, stacking hand trucks, or handling freight can have on the body. In fact, truck driving is always at or near the top of OSHA’s list of professions for lost work due to injury. In this case study we have gone through the various types of possible risk and injuries as well as ways to prevent injuries from occurring. The ergonomics of truck drivers has been applied and we know how truck drivers can work
THE IMPORTANCE OF SLEEPING WELL Hello everybody, I’m going to speak about the most time-consuming activity in our lives: sleeping. As a matter of fact, we usually don’t pay much attention to the quality of our sleep, in spite of influencing a big deal our performance during the day, our health and well-being, in other words, our quality of life. That’s the reason why I would like to introduce some interesting material to understand better this important though disregarded necessity.
