2: Drug-impaired driving Risky driving behavior No. Among them, the negative influence of video calls on driving safety was significantly higher than that of hands-free calls, with a significant decrease in VSC, and the drivers VSC in the free flow scenario was more sensitive to the impact of cell phone call operation, and the driving risk increased significantly during distracted driving. In contrast, the distribution of VSC was more discrete in free flow, indicating that VSC was more sensitive to the influence of the driving state in this traffic condition, and the value fluctuation interval was larger. Compared to alcohol-only users, drivers who admitted to using both were more likely to report such behaviors as: Unsurprisingly, the study found drivers who neither drink alcohol nor use marijuana were considerably less likely to engage in the sorts of risky driving behaviors examined. In automated driving, risk describes potential harm to passengers of an autonomous vehicle (AV) and other road users. Alcohol creates a sense of false confidence which can lead to risk-taking behaviour behind the wheel. Risky driving behaviors increase as common sleep disorder worsens Diagnosing, treating sleep apnea may make driving safer for older adults by Tamara Bhandari April 14, 2022 Getty Images Up to half of older adults may have sleep apnea, a condition in which breathing and sleep are briefly interrupted many times a night. 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). 16831706, 2020. In this article, we investigated the influence of the combined effect of traffic conditions and driving states on drivers visual behavior by constructing four visual characteristics indicators, IEFA, saccade amplitude, PARSV, and RCPA, combined with descriptive statistics and ANOVA methods. Therefore, the division of visual field areas and the accurate representation of the distribution characteristics of drivers fixation areas are the basis for studying drivers visual characteristics. Drivers must maintain the same attention to speed, control and alertness as driving on any urban roadway or highway. After risky driving behavior was added, the sensitivity of the model for traffic crash detection was 93.00%, and the false alarm rate was 12.99% in the XGBoost algorithm, which had an increased accuracy of 8% and a nearly 5% reduction in the false alarm rate. Lytx MV+AI distraction detection and alerting technology is designed to respect driver privacy because it does not collect, store or use any biometric identifiers or biometric information (i.e., scans of facial geometry) to detect distracted driving behaviors. 372379, 2007. (3)Calculate the grey correlation coefficient. 8, pp. 1589815908, 2022. More than 50% of drivers involved in serious injury and fatal crashes tested positive for at least one drug. 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]. Then, according to the data statistics and ANOVA results, the sensitive indicators for measuring visual stability under different traffic conditions were selected. Risky driving behavior was measured the Behavior of Young Novice Drivers Scale (BYNDS), developed by Scott-Parker et al. Euclidean distance was used to establish the distance matrix of the dataset, and the UPGMA algorithm was used to calculate the distance between the two clusters to complete the hierarchical aggregation process. Compared with the normal driving state, the correlation coefficients of drivers in cell phone calls showed different degrees of decrease, and the correlation coefficients in the video call state decreased sharply, and the values fluctuated significantly. API integrations. Drivers and passengers who fail to buckle up when they get into a car face high risks in the event of a crash 47% of passenger vehicle occupants who were killed in 2019 in crashes were not wearing seat belts. At this time, the mutual interference between vehicles was obvious, showing the speed adaptation characteristics, and the road was continuously congested. 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, , . Throughout June, July and August, Lytx processed more than 15 million driving events captured by its best-in-class, MV+AI-powered DriveCamEvent Recorders. 22, p. 15354, 2022. We have an advertising relationship with some of the offers included on this page. In different traffic flow scenarios, the mean saccade amplitude of drivers in the cell phone operation state generally increased compared with the normal driving state, and the growth rates of the hands-free call state were relatively low, 4.91% and 8.53% in free flow and congested flow, respectively, while the mean saccade amplitude of video call state increased dramatically, with growth rates of 50.29% and 91.26%, respectively. 3, pp. Drivers should never wait for a warning before taking measures to avoid an accident. Distracted driving refers to the behavior of drivers who voluntarily or involuntarily allocate their attention to other secondary tasks unrelated to the main driving task during driving [1], causing drivers visual and cognitive resources to be occupied to varying degrees, reducing drivers environmental perception, decision-making ability, and 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.. However, the distribution of fixation data collected by the eye tracker is discrete, and the pattern is not obvious. Studies have also shown that hands-free calls have no less negative impact on driving performance than hand-held calls [26]. 128, no. (5)Calculation of indicator information quantity. If you are convicted of a DUI, you may lose your driving privileges and your auto insurance policy could be canceled. risky behavior *Carinsurance.com is not affiliated with any state or government agency. 430443, 2018. Lytx clients coached 3 million risky driving events this summer. 2, pp. 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.

Zeng, Hierarchical clustering nodes collaborative scheduling in wireless sensor network, IEEE Sensors Journal, vol. This is due to the increased complexity of the driving environment in the congested flow scenario, where drivers need to pay attention to the changes in the traffic flow in front of them at all times, which makes it more challenging to extract information, reducing the saccade range. Drowsy driving is another risky driving behavior and can lead to impaired cognition and performance and motor vehicle crashes. Currently, the design of distracted driving scenarios for cell phone operation focuses on basic test scenarios such as highways, rural roads, and urban roads, which usually control single traffic conditions for test studies [32]. In addition, the existing research results focus on the visual recognition characteristics of drivers distracted by operating cell phones in a single traffic condition of the same road type, with few studies carried out under different traffic conditions. During driving, drivers constantly search and process external environmental information through the vision to ensure driving safety. But because driving comes so easily, we often forget how dangerous it can be. 2022, Article ID 7213814, 15 pages, 2022. 2020, Article ID 8878265, 14 pages, 2020. In the two traffic conditions, the mean RCPA in the cell phone operating state was generally higher than that in the normal driving state, and the growth rates of RCPA in the hands-free call were low, 2.79% and 12.33% in free flow and congested flow, respectively, and the change in RCPA was mainly caused by the increased psychological and physiological load of the drivers. 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. According to the U.S. Department of Transportations National Highway Traffic Safety Administration, which recently released its latest projections for 2022 traffic fatalities, an estimated 31,785 people were killed in traffic crashes in the first nine months of last year just a slight decrease from the 31,850 estimated deaths that occurred during the same period in 2021. a Percentages include responses of a few times, fairly often, or regularly., b Percentages include responses of just once, a few times, fairly often, or regularly., About AAA: AAA provides more than 62 million members with automotive, travel, insurance, and financial services through its federation of 30 motor clubs and more than 1,000 branch offices across North America. If you receive a ticket for texting and driving, its likely to drive up your auto insurance rates. During the test, the SV in the congested traffic flow needed to maintain a low-speed driving state, allowing overtaking and lane change. Considering the actual speed of the urban expressway and the ability to follow the vehicle in the simulated driving environment, the speed of the LV was designed to be 65km/h. In the two traffic conditions, the mean VSC of drivers in the cell phone operation state generally decreased compared to the normal driving state, with a lower decrease rate in the hands-free call state, 4.80% and 2.86% in free flow and congested flow, respectively, while the decrease rates of the mean VSC in video call state reached 28.46% and 25.05%, respectively, further indicating that the impact of video call operation on drivers driving safety is significantly higher than that of hands-free call. The most common distraction research is on cell phone call operations, which is a continuous and cumulative distraction process, and the research usually focuses on hand-held and hands-free calls. 2672, no. 17861798, 2022. Combined with the mechanical division method, the fixation area was divided into six parts, in which: A is the left rear view mirror; B is the road ahead, which is the main focus area during driving; C is the distant areas of the road ahead; D is the vehicle dashboard area; E is the cell phone placement area of the central console; and F is the right rear view mirror. Set. 28, no. Since there are often differences in the scale and order of magnitude of visual characteristics indicators, the use of standard deviation cannot accurately reflect the degree of variation of the indicators.

The factors causing the change were the brightness difference between the cell phone screen and the scenario display equipment, and the increased psychological and physiological load of the drivers during distracted driving, so the RCPA changed significantly under the coupling effect of the two factors. Therefore, driving distraction is a major factor affecting the safety of the road traffic system [1416]. The significance level is set to 0.1, then =1.25, and the value range of is between 0.25 and 0.5. In order to quantitatively characterize the influence of cell phone call mode on the drivers visual behavior in different traffic conditions and to analyze the risk level of distracted driving from the visual level, a distracted driving simulation test was Risky 3: Distracted driving, Risky driving behavior No. 100103, 2019. Machine Vision and Artificial Intelligence, Do Not Sell or Share My Personal Information. The coordinates of fixation points of the 18 drivers were hierarchical clustering, and the intercluster distance decreased with the increase of the number of clusters and finally stabilized gradually with six clusters as the cut-off point. Comparison of drivers VSC for each driving state in different traffic conditions. 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. In contrast, the drivers pupil area in the congested flow scenario increased sharply due to the complex driving environment in the congested flow scenario, which required the drivers to observe the road information all the time and invest more visual cognitive resources to adjust the driving state to ensure safe driving.
