aaa foundation for traffic safety drowsy driving

These crashes resulted in significant property damage, airbag deployment, rollover, injury, or substantial change in speed associated with the crash impact. According to the National Sleep Foundation’s Sleep in America poll, 60% of Americans have driven while feeling sleepy and 37% admit to actually having fallen asleep at the wheel in the past year. The National Sleep Foundation is raising awareness of the danger of driving while drowsy, and educating drivers on sleep safety in an effort to reduce the number of fatigue-related crashes and to ultimately save lives. It is the sum of all our fears. National Highway Traffic Safety Administration. Crashes in which the driver’s eyes were not visible for  at least 75% of the coding period (e.g., due to glare, dark sunglasses, or poor video quality) or in which the driver was not in the driver’s seat for the entire coding period were also excluded (n=204). Tefft, B. C. (2017). (2015). More than a quarter of those surveyed admitted they drove despite being so tired that they had difficulty keeping their eyes open in the previous month. Naturalistic Driving Study: Technical Coordination and Quality Control. Washington, D.C.: Transportation Research Board. The same study found that 109,000 of those drowsy driving crashes resulted in an injury and about 6,400 were fatal. The Traffic Safety Culture Index (TSCI) is a nationally representative survey that has been conducted annually since 2008 to identify American drivers’ perceptions, attitudes, and behaviors related to traffic safety issues. Aggressive driving has increasingly become a major cause of concern for many road users. (2015). Fatal Crashes Involving Drivers Recorded as Asleep or Fatigued 2013: Analysis Brief. With fall activities in full swing and the end of daylight saving time, there is a greater risk for drowsiness behind the wheel. Rates of Motor Vehicle Crashes, Injuries, and Deaths in Relation to Driver Age, United States, 2014-2015 (Research Brief). While the proportion of crashes that occurred in darkness in the current study was similar to the corresponding proportion among all police-reported crashes nationwide The AAA Foundation for Traffic Safety's report, Prevalence of Drowsy Driving Crashes: Estimates from a Large-Scale Naturalistic Driving Study, is based on the analysis of in-vehicle video footage of crashes that occurred during the Second Strategic Highway Research … View All Articles. Using this measure, drowsiness was identified in 8.8%–9.5% of all crashes examined and 10.6%–10.8% of crashes that resulted in significant property damage, airbag deployment, or injury. Missing one to two hours of sleep doubles a driver’s crash risk, while foregoing two or three hours increases the risk of a crash by 400 percent, according to the AAA Foundation for Traffic Safety study. Those who sleep for less than four hours … In extreme cases, all relevant information about the driver’s pre-crash state is lost if the driver is deceased and there are no passengers able to provide information about the driver’s pre-crash state. AAA Foundation. Download ». Other studies have attempted to estimate the proportion  of crashes that involve driver drowsiness by developing statistical models that distinguish between crashes that involved drowsiness versus those that did not, based on readily observable crash characteristics, in samples of crashes in which drowsiness was confirmed with some degree of confidence. The data analyzed for this study were collected as a part of the federally funded Second Strategic Highway Research Program Naturalistic Driving Study (SHRP 2 NDS). Results were similar in analyses limited to police-reportable crashes, with 10.6% involving drowsiness. Report DOT HS 808 247. (1998). “Drowsy driving is a bigger traffic safety issue than federal estimates show,” said Dr. David Yang, executive director for the AAA Foundation for Traffic Safety. Washington, D.C.: National Highway Traffic Safety Administration. Briefly, 3,593 drivers were recruited at various times from six sites around the U.S. to participate in a study in which their driving and in-vehicle behaviors were monitored continuously using in-vehicle cameras and other data collection equipment for a period of several months between October 2010 and December 2013 as they drove in t… DOT HS 812 384). People who are very sleepy behave in similar ways to people who are drunk. No fatal crashes occurred in the SHRP 2 NDS, so the results of the current study cannot be generalized directly to fatal crashes. References. Approximately 31% of crashes examined were classified as severe or moderately severe. Slow eyelid closure as a measure of driver drowsiness and its relationship to performance. The AAA Foundation for Traffic Safety says six to ten percent of all reported crashes across the U.S. involved drowsy driving. In fact, the AAA Foundation for Traffic Safety says that people who sleep 6-7 hours a night are twice as likely to be involved in a crash than are people who sleep 8 hours a night. Results were similar in analyses limited to police-reportable crashes, with 10.8% of these higher-severity crashes involving drowsiness. The Drowsy Driver Warning System Field Operational Test: Data Collection Methods. Journal of Clinical Sleep Medicine, 11(6): 591-592. Drowsy driving is a serious problem in the United States. The results of this study stand in stark contrast to official statistics published by the National Highway Traffic Safety Administration (NHTSA), which report that driver drowsiness was involved in an estimated 1.4% of all police-reported crashes nationwide, 2.0% of crashes that resulted in injuries and 2.4% of crashes that resulted in a death in years 2011–2015 (National Center for Statistics & Analysis, 2017). Masten, S. V., Stutts, J. C., Martell, C.A. (2017, October). Acute Sleep Deprivation and Risk of Motor Vehicle Crash Involvement. Drowsy Driving AAA Foundation for Traffic Safety. In the current study, drowsiness was assessed using the PERCLOS measure, which is the percentage of time that a person’s eyes are closed over a defined measurement interval (Wierwille et al., 1994). Report No. This is the National Sleep Foundation's Drowsy Driving Prevention Week, and the AAA Foundation for Traffic Safety has completed a new survey with data indicating that one in … These results suggest that driver drowsiness is a substantially larger problem than official government statistics indicate. Tamra Johnson That doesn’t stop many of us from driving drowsy, though. That's more than three times the police-reported number. Read our Privacy Policy. Traffic Injury Prevention, 17(3): 251-257. In an effort to reduce this alarming trend in traffic safety, AAA presents Fatigued Driving programs to motorists. A. Washington, D.C.: National Highway Traffic Safety Administration. (1994). Report No. (Dawson and Reid, 1997; Powell, 2001) The American Automobile Association (AAA) estimates that one out of every six (16.5%) deadly traffic accidents, and one out of eight (12.5%) crashes requiring hospitalization of car drivers or passengers is due to drowsy driving. Prevalence of Drowsy Driving Crashes: Estimates from a Large-Scale Naturalistic Driving Study; The Prevalence and Impact of Drowsy Driving; Federal Motor Carrier Safety Administration . Here are some suggestions for ways to avoid driving drowsy: Stop driving if you become sleepy. Previous research by the AAA Foundation for Traffic Safety has found that driving after having slept for less than seven hours in a 24-hour period is associated with measurably elevated crash rates (Tefft, 2016). Collectively, these results provide additional suggestive evidence that the proportion of fatal crashes that involve driver drowsiness is likely substantial. As in previous studies, the driver was classified as drowsy if the driver’s eyes were closed in 12% or more of the video frames in the three-minute or one-minute period preceding the crash (Wierwille et al., 1994; Hanowski et al., 2008). “Drowsy driving is a bigger traffic safety issue than federal estimates show,” said Dr. David Yang, executive director for the AAA Foundation for Traffic Safety. Overall, the driver was classified as drowsy in 9.5% of all crashes. Table 1 shows the breakdown of crashes examined in this study by age and sex of the driver involved, lighting conditions present and the severity of the crash. Hankey, J. M., Perez, M. A., McClafferty, J. Experts recommend that adults should sleep for least seven hours each night for optimal health (Watson et al., 2015). The AAA Foundation for Traffic Safety’s report, Prevalence of Drowsy Driving Crashes: Estimates from a Large-Scale Naturalistic Driving Study, is based on the analysis of in-vehicle video footage of crashes that occurred during the Second Strategic Highway Research Program’s Naturalistic Driving Study (SHRP 2 NDS). DOT HS 811 035. It is possible that these drivers and their behavior differed somewhat from the population at large; the extent to which they may be more or less likely than members of the general population to drive while drowsy is unknown. Thus, sources of data beyond standard police reports are necessary to develop accurate estimates of the proportion of crashes that involve driver drowsiness. Prevalence of motor vehicle crashes involving drowsy drivers, United States, 1999-2008. Washington, D.C.: National Highway Traffic Safety Administration. Drowsy driving is a prevalent and serious public health issue that deserves more attention, education, and policy initiatives so a substantial amount of lives can be saved and disability averted due to drowsy driving accidents. They then used those models to estimate the proportion of all crashes that involved drowsiness. In the case of a driver who was not actually asleep at the time of the crash but was operating at a reduced level of alertness, the driver may not even recognize that he or she was drowsy nor that drowsiness may have contributed to the crash. Although not all of these crashes were necessarily reported to the police, they were severe enough to have likely met the police-reporting thresholds in most jurisdictions (Hankey et al., 2016). National Highway Traffic Safety Administration. Dinges, D. F., Mallis, M. M., Maislin, G., Powell, J. W. IV. (26%), the proportion of fatal crashes that occur in darkness is much higher, at 48% (NHTSA, 2017). It is an extension of AAA's long history of public service and provides a look into important safety, consumer, automotive and travel issues. According to AAA Foundation for Traffic Safety research: Ninety-six percent of motorists view drowsy driving as very or extremely dangerous, but 24% admitted to driving when they were so tired that they had a hard time keeping their eyes open at least once in the previous 30 days before the survey (2019 Traffic Safety Culture Index). NCHRP Report 500. Research on Vehicle-Based Driver Status/Performance Monitoring; Development, Validation, and Refinement of Algorithms for Detection of Driver Drowsiness. By applying a validated measure of drowsiness to a sample of crashes captured on video in a large naturalistic driving study involving members of the general driving population, this study found that 8.8%–9.5% of all crashes and 10.6%–10.8% of crashes severe enough to be reported to the police involved driver drowsiness. Earlier this month, we recognized the dangers of driving while tired during National Drowsy Driving Prevention Week (Nov 3-10). Traffic Safety 11/3/2014 More than One-in-Five Fatal Crashes Involve Drowsy Drivers. The AAA Exchange was designed to foster communication between AAA and the 59 million members it represents. Washington, D.C.: Transportation Research Board. The impact that this has on traffic safety should not be underestimated. Ultimately, PERCLOS was coded for the full three minutes preceding each of 589 crashes and for one minute preceding each of an additional 112 crashes (701 total). Variation by age, sex, and crash severity was not statistically significant (all P > 0.20). 50th Annual Proceedings of the Association for the Advancement of Automotive Medicine; Chicago, IL; October 2006. One such study by Masten et al. Briefly, 3,593 drivers were recruited at various times from six sites around the U.S. to participate in a study in which their driving and in-vehicle behaviors were monitored continuously using in-vehicle cameras and other data collection equipment for a period of several months between October 2010 and December 2013 as they drove in their own vehicles. Table 2 shows the number and proportion of crashes in which the driver was found to be drowsy based on PERCLOS calculated over the three minutes immediately prior to the crash. Sleepiness slows your reaction time, decreases awareness and impairs your judgment, just like drugs or alcohol. Finally, it is possible that some drivers who did not meet the current study’s criteria for classification as drowsy (i.e., eyes closed for 12 percent or more of the one- or three-minute coding window) may have nonetheless been drowsy at the times of the crashes. SHRP 2 Report S2-S31-RW-1. Drowsy Driving – AAA Exchange “You cannot miss sleep and still expect to be able to safely function behind the wheel,” said Dr. David Yang, executive director for the AAA Foundation for Traffic Safety. Predicting daytime and nighttime drowsy driving crashes based on crash characteristic models. We urge motorists to get the full recommended amount of … Drivers under age 25 accounted for more than half of all crash-involved drivers in the current study, compared with 23% of all crashes nationwide (NHTSA, 2017). (2015). Wierwille, W. W., Wreggit, S. S., Kirn, C. L. Ellworth, L. A., & Fairbanks, R. J. In addition, the SHRP 2 NDS oversampled younger and older drivers. This time you were lucky; next time you could become the latest victim of the tragedy of drowsy driving. Driver Behavior & Performance. Experts have long regarded such statistics, derived from police reports based on post-crash investigations, as vast underestimates of the scope of the problem. In 2018, the questionnaire was revamped to include more measures such as perceived danger, risk of arrest, personal and perceived social approval of risky driving, support for laws and policies designed to curtail these be… Stutts, J., Knipling, R. R., Pfefer, R., Neuman, T. R., Slack,  K. L., Hardy, K. K. (2005). Report DOT HS 808 Tefft, B. C. (2016). Naturalistic Driving Study: Descriptive Comparison of the Study Sample with National Data. Stowe, L. (2015). It’s estimated that 300,000 crashes every year involve drowsy driving, which also contributes to up to 6,400 deaths per year, according to the AAA Foundation for Traffic Safety. Thus, the results of the current study corroborate the general conclusions of previous studies, namely that crashes involving driver drowsiness are much more prevalent than official statistics indicate. Results indicated that observable driver drowsiness, assessed on the basis of eyelid closures, was present in an estimated 8.8%–9.5% of all crashes and 10.6%–10.8% of those severe enough to be reportable to the police.

Recommended amount of sleep for a healthy adult: A joint consensus statement of the American Academy of Sleep Medicine and Sleep Research Society. 762. AAA began providing emergency roadside assistance in 1915, using a fleet of motorcycles to aid stranded motorists. Even so, almost 1 in 3 also admitted that, at some point in the previous month, they themselves had driven while having a hard time keeping their eyes open. “Drivers who don’t get enough sleep are putting everyone on the road at risk. This study has several limitations that should be noted. Watson, N. F., Badr, M. S., Belenky, G., et al. (2008). 2019 Traffic Safety Culture Index. DOT HS 812 446). Most motorists (96%) identify drowsy driving as very or extremely dangerous, according to the AAA Foundation for Traffic Safety 2018 Traffic Safety … Drowsiness was assessed using a validated measure that is based on the percentage of time that a person’s eyes are closed. Also of note, more than half of all crashes that involved drowsiness occurred in darkness. Sleepiness slows your reaction time, decreases awareness and impairs your judgment, just like drugs or alcohol. This study examines in-vehicle video captured in a large naturalistic driving study to estimate the proportion of motor vehicle crashes that involve drowsy driving. “Our new research shows that a driver who has slept for less than five hours has a crash risk comparable to someone driving drunk.” We can all use a reminder of the dangers of drowsy driving. TRJohnson@national.aaa.com. Washington, D.C.: Transportation Research Board. Here are some findings from a 2016 AAA Foundation for Traffic Safety study. Description of the SHRP 2 Naturalistic Database and the Crash, Near-Crash, and Baseline Data Sets. “This new research further confirms that drowsy driving is a serious traffic safety problem,” warned Peter Kissinger, President and CEO of the AAA Foundation for Traffic Safety. NHTSA Drowsy Driving Research and Program … Traffic Safety Programs & Materials A study by the AAA Foundation for Traffic Safety estimated that 328,000 drowsy driving crashes occur annually. Feeling sleepy is especially dangerous when you are driving.

Blacksburg, VA: Virginia Tech Transportation Institute. Washington, D.C.: National Highway Traffic Safety Administration. American Automobile Association Foundation for Traffic Safety, 2010. “Unfortunately, drivers often underestimate this risk and overestimate their ability to combat drowsiness behind the wheel.” The sample was generally representative of the driving public with the exception that younger and older drivers were deliberately oversampled. Starting a trip feels exciting, but the alertness wears off, letting boredom and drowsiness take over. This is the first study to use the validated PERCLOS measure to quantify the proportion of crashes in which the driver was drowsy using pre-crash video from a large sample of crashes that involved members of the U.S. general driving population. Traffic Safety Facts 2015. Founded in 1947, the AAA Foundation for Traffic Safety is dedicated to saving lives by preventing traffic crashes and reducing injuries when crashes occur. Volume 14: A Guide for Reducing Crashes Involving Drowsy and Distracted Drivers. Questions or comments? National Center for Statistics and Analysis. 1 in 3 drivers A total of 905 severe, moderate, and minor crashes that occurred during the SHRP 2 NDS were initially included in the current study; this number did not include 628 other crashes that were classified as “low-risk tire strikes.” (Hankey et al. Sleepiness can impair driving performance as much or more so than alcohol, studies show. A new study from AAA states that drivers who skimp on the seven hours of sleep experts recommend increase their risk of a crash exponentially. The final one minute of video preceding the crash was analyzed if three full minutes of usable data were not available. The impact that this has on … Traffic Safety 12/6/2016 Missing 1-2 Hours of Sleep Doubles Crash Risk. “Drivers who don’t get enough sleep are putting everyone on the road at risk. Stutts et al.

J., Blanco, M., Nakata, A., et al. Produced by the AAA Foundation for Traffic Safety, this brochure provides tips on how to avoid driving while sleepy. According to AAA Foundation for Traffic Safety’s 2019 data, nearly 80 percent of drivers expressed significant anger, aggression or road rage behind the wheel at least once in the previous 30 days. How to Pay for Roads, Bridges, and Transit. The operational definition of “closed” was that the eyelids were more than 80% closed or covering the pupil. Feeling sleepy is especially dangerous when you are driving. 202-942-2079 PERCLOS has been shown to be predictive of drowsiness, lapses in attention, and increased variability in lane position (Wierwille et al., 1994; Dinges et al., 1998; Jackson et al., 2016). The proportion of crashes that involved drowsiness varied significantly in relation to lighting conditions (P < 0.001); variation by age, sex, and crash severity again were not statistically significant (all P ≥ 0.17). Naturalistic driving data can provide a unique window into the state of the driver in the moments leading up to a crash. Unlike impairment by substances such as alcohol, there  is no test analogous to a breathalyzer that the police can administer at the roadside to assess a driver’s level of drowsiness at or shortly after the time of a crash. SHRP 2 Report S2-S06-RW-1. Driver drowsiness is an under-reported traffic safety problem, largely because its role in crashes is typically difficult to ascertain. Trained data reductionists viewed the final three minutes of video preceding each crash (recorded at 15 frames per second) frame-by-frame and coded whether the driver’s eyelids were open or closed in each frame. People who are very sleepy behave in similar ways to people who are drunk. The proportion of crashes that involved drowsiness varied significantly in relation to lighting conditions (P < 0.001; Fisher’s exact test), with drowsiness evident in over three times the proportion of crashes in darkness as in daylight. Jackson, M. L., Raj, S., Croft, R., J., Hayley, A. C., Downey, L. A., Kennedy, G. A., Howard, M. E. (2016). In a more subjective assessment of drowsiness not included in the current study, data reductionists viewed only the final six seconds of video prior to each crash and coded drowsiness based only on obvious signs (e.g., yawning, rubbing eyes, slack musculature, etc.). It also surveyed 228 million drivers this past year and says 4.6 million admit to regularly driving when they're so tired they have a hard time keeping their eyes open. Table 3 shows the number and proportion of crashes in which the driver was found to be drowsy based on PERCLOS calculated over only the final one minute prior to the crash, which enabled the inclusion of 112 additional crashes for which three full minutes of video were not available. Take a mid-afternoon nap and find a place to sleep between midnight and 6 a.m.; and. (2006) estimated that approximately 15% of all drivers involved in fatal crashes in the U.S. were drowsy. Drowsy Driving. People who are very sleepy behave in similar ways to people who are drunk. A high proportion of crashes involved drivers under age 25, a consequence of both their elevated crash rates (Tefft, 2017) and the deliberate oversampling of younger drivers in the SHRP 2 NDS (Antin et al., 2015). In addition, other studies such as Tefft (2012) have estimated that drowsiness is a factor in a much greater percentage of fatal crashes than in less severe crashes. In this more subjective assessment, a small number of additional drivers who did not meet  the objective PERCLOS-based criteria for drowsiness were judged to have been drowsy at the times of crashes.
