That more accurately was able to define this program in an ongoing manner, what would that look like . Ideally, if every vehicle on the road or at least a large sample on an ongoing basis were equipped with sophisticated Data Collection equipment, including cameras, that would give us a great deal of insight into many of the intervening factors of crashes, including drowsiness. Short of that, i would really like to see in the National Data , which i believe is the only ongoing data system that has the means to make a reasonable determination of andher a driver was drowsy whether fatigue contributed to the crash, not in the same way but much better than simple investigation of police reports. Collection system and to be beefed up in size a number of investigations were to be done each year and of ,ittle more depth were added analogous perhaps to the Motor Vehicle Crash Causation survey, which was a one time ever done to 2007, with not only the drivers but their families, their employees
Driver. If we do not have a concerted effort to teach children, adolescents, who are at risk in this area, shift workers, and average people who push themselves very hard and does not get adequate sleep, if we do not make a concerted effort to make sleep a priority, in addition to all of the other things we can do to protect drivers, we are, in effect, not dealing with the core source of the problem, and that is inadequate sleep and operating a motor vehicle. You spoke about banking sleep or recovery sleep. If a person is either chronically or acutely sleep deprived, how much time does it take to pay back sleep . If they have enough sleep, are they then safe to perform after . Thank you for the question. It is not as easy to answer as i would like it to be. The estimates we have been studying this for the National Institutes of health and other agencies. It appears that the old belief that you can make it all up in one night is not supported by the evidence. That belief came about by o
Officialed attributed to fatigue underestimated. There is no roadway test. Fatiguedness. We do not have a fatiguealyzer as we do a breathalyzer. State reporting practices are inconsistent and theres little or no Police Training in identifying drowsiness as a crash factor. Self reporting is unreliable. Do know. We any resulting loss of life is tragic, needless and preventible. A drowsy driver can be a deadly driver. Even one night losing two hours of sleep is sufficient to significantly impair our a little bit attention, reaction time, Decision Making can all be significantly reduced by 20 to 50 , and driving in this condition, that could mean not brake lights in front of us or not seeing the traffic light turning red. Fatigue alone can be deadly. It also multiplies the adverse effects of other forms of pairment that lead to crashes such as drugs, alcohol and distraction. Every other form of impairment may be exacerbated when the basic requirement for sleep is disrupted. Weve identified
For commercial and bus drivers. Most people drive cars. They operate personal vehicles. For most of us, there are no hours of service or rest rules. We have to rely on our own experience for knowledge of fatigue and its affects. Unfortunately, our personal experience especially as it relates to selfdiagnosing fatigue is typically inaccurate. In january 2013, the ntsb investigated a collision involving three passenger vehicles. The collision happened at about 8 30 in the morning. A nurse was driving home after more than 13 hours on duty. She depart her lane, crossed over the median and entered a northbound lane traveling against the flow of traffic. Her car then struck another vehicle, pushing it into one lane over. This vehicle was struck again from behind by another car. One driver was fatally injured and the 234urs was transported to a hospital where she was treated for her injuries. She had fallen asleep.

I would note that, in recent the raw number of crashes and deaths nationwide has decreased and that is a good thing. There is anyeve evidence based on the best the problemta that is increasing or decreasing as a share of all crashes. If we look or use conservative estimates that we have across of of the more solid studies the proportion of crashes that involved drowsy drivers and wely that to 2012 data, estimate over 5000 were killed in crashes that involved a drowsy driver. You mentioned multiple you look atnd alcoholimpaired driving. I am wondering if you can use the same technique on that data to look at fatiguerelated crashes. If so, or if not, what would your opinion be . I believe it could be done. I would only do that with a couple of the data from studies that i referred to in my presentation. The National Motor vehicle Crash Causation survey and automotive sampling system. Researchers,ies, independent of the police, make the determination of whether a driver is drowsy. They di
