These data show the alarming impact of alcohol and marijuana use on the choices drivers make when they get behind the wheel, said Jake Nelson, AAAs director of traffic safety advocacy and research. Because of this, seatbelt use is one of eight behaviors we proactively issue in-cab alerts for, helping drivers to self-correct in real-time.. Recent studies suggest that human-like According to government data, alcohol and marijuana are the most widely used drugs in the United States 139.8 million people aged 12 or older reported drinking alcohol in the past month, and 43.5 million reported using marijuana in the past year. 2672, no. The correlation coefficients of the corresponding elements of each comparison sequence and the reference sequence are calculated, respectively, as follows: Calculate the grey correlation degree. In order to analyze the stability of drivers visual information processing in different driving states and evaluate the negative impact of different driving states on driving safety based on microscopic visual characteristics indicators, the comprehensive scores of drivers visual characteristics indicators in different driving states under two traffic conditions were calculated, respectively, based on the objective weighting results of the improved CRITIC method, which were defined as the visual stability coefficient (VSC) of drivers. 4, pp. Dropdown to filter by a specific type of media, Speeding on residential streets (55%) vs. alcohol-only (35%), Aggressive driving (52%) vs. alcohol-only (28%), Intentional red-light running (48%) vs alcohol-only (32%), Texting while driving (40%) vs. alcohol-only (21%). Copyright Lytx, Inc, 2023. In the comprehensive evaluation of multiple indicators, different weighting methods will cause differences in the evaluation results, so it is necessary to choose the weighting methods scientifically and reasonably in combination based on the characteristics of the indicator and the research object [34]. Deliver value to your customers by offering smart and simple video dash cam technology.. There were 697 drowsy-driving-related crashes in 2019. In automated driving, risk describes potential harm to passengers of an autonomous vehicle (AV) and other road users. There were 697 drowsy-driving-related crashes in 2019, according to the NHTSA. The road length was 20km, the lane width was 3.5m, and the speed limit was 80km/h. Webrisky driving episode. Using the worlds largest driving database of its kind, along with proprietary machine vision and artificial intelligence technology, we help protect and connect thousands of fleets and more than 1.3 million drivers worldwide. Recent studies suggest that human-like driving behavior emerges from embedding risk in AV motion planning algorithms. Nowadays, many countries regulate the use of cell phones while driving and most explicitly prohibit hand-held calls, but there are no clear requirements for other cell phone call methods [27, 28]. ORIGIN, SPSS, and Begaze software were used to process and analyze the collected eye movement data. The decision matrix is constructed as follows: Determine the reference sequence and comparison sequence. One-way analysis of variance (ANOVA) was adopted on the data using statistical methods to investigate the differences in IEFA of drivers in different driving states under two traffic conditions. One-way ANOVA of the influence of driving state on PARSV. She most recently worked in the public sector for the Nevada Department of Transportation. The distracted driving test platform was built based on driving simulation technology, and the developed simulation scenarios were imported into the driving simulator, with the operation control platform for scenario fusion and system debugging work to complete the platform construction, combined with the eye tracker and the supporting Begaze analysis software for driving simulation tests. Compared with the normal driving state, most drivers were in a state of cognitive distraction during the hands-free call, narrowing their field of view and reducing the breadth and depth of their search for information about the surrounding road conditions. 1, p. 5262, 2022. Lytx clients coached 3 million risky driving events this summer. 22, p. 15354, 2022. Alcohol impairment is scientifically shown to reduce driver response times and reaction times, thereby greatly increasing the potential for a crash, says Sam Morrissey, former executive director of Urban Movement Labs, a nonprofit working to design and deploy transportation technology. (2)Determine the reference sequence and comparison sequence. Some behaviours that contribute to severe and even fatal injuries in RTCs include failing to wear a seatbelt and being distracted. The two-way ANOVA was adopted, as shown in Table 11, in which both traffic conditions and driving states significantly influenced the drivers RCPA, but their interaction had no significant influence on RCPA. Information entropy is an indicator to quantify the amount of information in information theory, borrowed from thermodynamics and measures the ordering degree of a system. Young drivers, who lack the experience and judgment to break for a rest, are the most likely to have fallen asleep at the wheel, according to the AAA Foundation for Traffic Safety. That adds up to one person every 52 minutes dying in preventable crashes. J. L. Harbluk, Y. I. Noy, P. L. Trbovich, and M. Eizenman, An on-road assessment of cognitive distraction: impacts on drivers visual behavior and braking performance, Accident Analysis & Prevention, vol. 132142, 2017. Alcohol, marijuana, and other drugs slow coordination, judgment and reaction times. Our customizable services and programs span driver safety, risk detection, fleet tracking, compliance, and fuel management. 3: Distracted driving, Risky driving behavior No. At this time, the mutual interference between vehicles was obvious, showing the speed adaptation characteristics, and the road was continuously congested. Cell phone call operations during driving can lead to distraction and cause potential safety hazards. 430443, 2018. Webphones sometimes or often while driving are more likely to drive 10 mph over the limit on local roads than people who rarely or never use the cell phone while driving. While drivers consistently acknowledge that certain risky behaviors behind the wheel, such as speeding and driving impaired, are not safe, many still engage in In the process of driving, the drivers need to perceive various road traffic information in real-time, and the visual system is the main way to obtain the information [1012]. Distracted driving is another risky behavior. Peak-to-average power ratio (PAPR) is a common indicator in the field of communication technology, used to describe the dynamic variation range of the signal envelope as the ratio of the peak power to the average power of a time-domain signal [49]. The sampling frequency of the eye tracker was set to 200Hz, and the supporting software Begaze2.4 was used to export the video and corresponding visual behavior text data for analysis and preliminary processing. Lets pinpoint new behaviors you want to do, so you can see And, yes, police interactions can be risky, but the people driving these vehicles are choosing to experience a police interaction when they brazenly break the law with their anti-social behavior and modified vehicles. Therefore, the test recruited 18 nonprofessional drivers as subjects, aged from 24 to 51years (mean value is 33.2, and the standard deviation is 9.8). Finally, the grey correlation analysis method was introduced to verify the assessment effect of VSC. The subjects had relatively free operation rights such as acceleration, deceleration, and braking, but were not allowed to overtake the LV. From 2010 to 2012, our commercial vehicles have a total of 742 cases of death more than 3 people traffic accident, which killed 3476 people and caused bad influence [ 1 ]. Of 3 million events coached this summer, the following five A. Fernandez, R. Usamentiaga, J. L. Carus, and R. Casado, Driver distraction using visual-based sensors and algorithms, Sensors, vol. During driving, drivers constantly search and process external environmental information through the vision to ensure driving safety. WebAffecting Risky Driver Behavior. However, this doesnt influence our editorial judgment or recommendations. Some prescription and OTC medicines can cause extreme drowsiness and dizziness. The data Lytx captures on a daily basis empowers drivers and fleets with the information necessary to help take their safety and productivity to new levels. Recent studies suggest that human-like driving behavior emerges from embedding risk in AV motion planning algorithms. * Subject to available cellular network coverage. G. M. Fitch, S. A. Soccolich, F. Guo et al., The impact of hand-held and hands-free cell phone use on driving performance and safety-critical event risk, in National Highway Traffic Safety Administration, Washington, DC, USA, 2013. 13, no. The IEFA of the drivers in different driving states under two traffic conditions was calculated, as shown in Figure 4. In contrast, the distribution of IEFA was more discrete in free flow, indicating that IEFA was more sensitive to the influence of the driving state in this traffic condition, and the value fluctuated more. Driving when so tired, it was hard to keep your eyes open (96%) Driving while typing or sending a text message or an email (96%) Yet these same drivers text 2020, Article ID 8878265, 14 pages, 2020. During driving, the main fixation area for drivers to obtain traffic information was the road ahead, so the clustering center of the road area ahead was taken as the centroid of the whole fixation area, and the distance of each fixation point from the centroid was divided into different intervals with a step size of 100px to reflect the offset degree of drivers fixation points.

The eye movement data of drivers during normal driving, hands-free call, and video call under two typical traffic conditions of free flow and congested flow on the urban expressway were collected. Comparison of drivers RCPA for each driving state in different traffic conditions. P. Papantoniou, Structural equation model analysis for the evaluation of overall driving performance: a driving simulator study focusing on driver distraction, Traffic Injury Prevention, vol. M. Wang and J. Zeng, Hierarchical clustering nodes collaborative scheduling in wireless sensor network, IEEE Sensors Journal, vol. Lytx technology is validated and backed by the largest and fastest-growing driving database of its kind. Throughout June, July and August, Lytx processed more than 15 million driving events captured by its best-in-class, MV+AI-powered DriveCamEvent Recorders. The analysis of the impact of cell phone call operations on driving safety was combined with the demand for driving attention due to the complexity of traffic conditions and also provided scenario modeling experience for studies related to distracted driving behavior. Therefore, driving distraction is a major factor affecting the safety of the road traffic system [1416]. 454468, 2012. In addition, the correlation coefficient between indicators may be negative, resulting in errors in the evaluation results. If you receive a ticket for texting and driving, its likely to drive up your auto insurance rates. One-way ANOVA of the influence of driving state on IEFA. Comparison of drivers VSC for each driving state in different traffic conditions. Comparison of drivers PARSV for each driving state in different traffic conditions. He et al., ID-YOLO: real-time salient object detection based on the drivers fixation region, IEEE Transactions on Intelligent Transportation Systems, vol. 7, pp. Confirmatory factor analysis showed that the questionnaire fitted properly in two correlated factors, labeled as Risky Driving and Aggressive Driving. A. Moustafa, Pupil dilation as an indicator of future thinking, Neurological Sciences, vol. Evaluation results of grey correlation analysis method. 1, pp. The smartphones used in the driving missions were equipped with the WeChat chat application. John is the editorial director for CarInsurance.com, Insurance.com and Insure.com. 575588, 2018. Wearing a seat belt reduces the risk of serious injury or death in a crash by up to 50 percent. WebKulendranM,PatelK,DarziA,VlaevI.Diagnosticvalidityofbehaviouralandpsychometricimpulsivitymeasures:Anassessmentinadolescentandadultpopulations.PersonalityandIndividualDifferences.2016;90:347352 But because driving comes so easily, we often forget how dangerous it can be. 55, pp. The specific region division is shown in Figure 2. The subjects wore and calibrated the eye tracker with the help of the staff, followed by a 10min pretest to get used to the wearing of the eye tracker and the control of the vehicle. 63, pp. K. Tahkoubit, H. Shaiek, D. Roviras, S. Faci, and A. Ali-Pacha, Generalized iterative dichotomy PAPR reduction method for multicarrier waveforms, IEEE Access, vol. In two traffic conditions, compared to the normal driving state, the VSC generally decreased when drivers were distracted, and the decrease in VSC during video calls was significantly higher than that of hands-free calls, indicating that the video call had a greater negative impact on drivers driving safety. The American Automobile Association (AAA) also found that those who drove more during the early pandemic were more likely than average to report recent risky driving behaviors, such as driving without a seat belt or speeding. Therefore, the hierarchical clustering method combined with the mechanical division method was used to divide the drivers fixation area. Weblap/shoulder seat belts are used properly, they reduce the risk of fatal injury to front-seat passenger car occupants by 45 percent and the risk of moderate-to-critical injury by 50 Most states 47 states plus the District of Columbia have laws against texting. In 2019, 10,142 people died in drunken-driving crashes. The saccade amplitude was mainly distributed from 6.67 to 24.76 in the free flow scenario and from 3.47 to 21.27 in the congested flow scenario. But it goes beyond texting and handheld cell phone usage it can be talking to people in your vehicle, eating and drinking or using your vehicles entertainment or navigation system. The specific steps of the grey correlation analysis method in this study are as follows:(1)The decision matrix is constructed as follows:where , denotes the visual evaluation indicator data of the th driver in the th driving state, , . Risky driving behavior was measured the Behavior of Young Novice Drivers Scale (BYNDS), developed by Scott-Parker et al. 20, no. Drivers must maintain the same attention to speed, control and alertness as driving on any urban roadway or highway. And 55% of those killed during nighttime in 2019 were unrestrained. In addition to environmental brightness, pupil size is also influenced by emotion, mental effort, perception, and attention, so pupil change is often regarded as an indicator of the psychological and physiological load on human [5355]. It seems as if this practice has become epidemic. The RCPA of the drivers in different driving states under two traffic conditions was calculated, as shown in Figure 8. Our Best Fleet Forward newsletter delivers monthly insights on fleet management.

The saccade amplitude is the range covered by the line of sight from the beginning to the end of a saccade, usually expressed in degrees of view [48]. According to the evaluation criteria of visual stability based on the cluster analysis, the percentage of drivers VSC in each interval for different traffic conditions and driving states is shown in Figure 9. About 28 people in the United States die in drunk-driving crashes every day. Limited time offer. In two traffic conditions, compared with the normal driving state, the percentage of the VSC in the stable interval (>0.63) decreased sharply and the percentage of VSC in the extremely unstable interval (<0.33) generally increased when the drivers were distracted by operating the cell phone, and the change of percentage in the video call state was more significant. We help protect more than 4,800 clients and 1.6 million drivers across the globe. T. M. Rudisill, H. Chu, and M. T. Zhu, Cell phone use while driving laws and motor vehicle driver fatalities: differences in population subgroups and location, Annals of Epidemiology, vol. 47, pp. Learn about the latest in fleet and compliance management through our comprehensive Resource Hub. In order to quantitatively characterize the influence of cell phone The VSC calculation equation is as follows:where denotes the VSC, is the weight coefficient of the th visual characteristics indicator, and is the data of the th visual characteristics indicator of the th driver after standardized processing. We as humans behave the way we do for one reason: to get what we need and want. Therefore, based on the calculation principle of the traditional CRITIC method, the standard deviation is replaced by the coefficient of variation, which eliminates the influence of different magnitude and indicator means on the indicator variability, while the correlation coefficient is taken as the absolute value in indicator conflict calculation, and the establishment process of the indicator weights by using the improved CRITIC method as follows:(1)Construction of original data matrix.
