Therefore, it is of great significance to explore the visual behavior characteristics of drivers in the process of distracted driving to evaluate the risk of distracted behavior. When drivers are in different degrees of distraction, visual behavioral indicators change correspondingly [32]. Finally, we constructed VSC as a new indicator for visual characteristics evaluation based on the weight calculation theory and established the evaluation criteria for visual stability, which can help to accurately quantify the stability of drivers visual attention and information processing under the coupling effect of traffic conditions and driving states, and comprehensively assess the risk bias of drivers states from the visual level, in order to provide the theoretical basis for the correction of drivers visual behaviors and driving safety. He, and Z. Zhang, Structural multi-objective topology optimization and application based on the criteria importance through intercriteria correlation method, Engineering Optimization, vol. The two-way ANOVA was adopted, as shown in Table 8, which indicated that the driving states had a significant influence on PARSV, while traffic conditions and their interaction with driving states had no significant influence on PARSV. The design content of the test is described in detail below. Before joining QuinStreet, John was a deputy editor at The Wall Street Journal and had been an editor and reporter at a number of other media outlets where he covered insurance, personal finance, and technology. Alcohol creates a sense of false confidence which can lead to risk-taking behaviour behind the wheel. A. Kalinov, R. Bychkov, A. Ivanov, A. Osinsky, and D. Yarotsky, Machine learning-assisted PAPR reduction in massive MIMO, IEEE Wireless Communications Letters, vol. Editorial Integrity - Why you should trust us? The two-way ANOVA was adopted, as shown in Table 6, in which both traffic conditions and driving states significantly influenced the drivers saccade amplitude, but there was no interactive influence between traffic conditions and driving states on saccade amplitude. By calculating the correlation coefficient between evaluation indicators and taking the absolute value, the conflict between indicators is measured. The correlation degrees of different driving states were consistent with the variation rule of mean VSC, which further verified the validity of the assessment results of VSC. According to the NHTSA, about 28 people in the United States die in drunk-driving crashes daily. Alcohol creates a sense of false confidence which can lead to risk-taking behaviour behind the wheel. Risky driving behavior does not have to result in a crash or collision to have serious negative consequences. (a) FFS. The larger is, the more information the indicator contains, the greater the importance in the evaluation system, and the higher the weight assigned. Therefore, driving distraction is a major factor affecting the safety of the road traffic system [1416]. We have an advertising relationship with some of the offers included on this page. WebChronic fatigue symptoms of jobs are risk factors that may cause errors and lead to occupational accidents. 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. While there are usually point systems assigned to state drivers licenses, the structure and frequency of penalties almost guarantee that only the most egregious drivers would face the stiffest penalties. 679687, 2022. The report on the economic impact of crashes also touched on the risky driving behaviors that lead to crashes, fatalities, serious injuries and property damage. The mean value of the correlation coefficient of the corresponding elements of the comparison sequence and the reference sequence is calculated to reflect its association with the reference sequence, which is called the correlation degree, as shown in the following equation: The larger the , the lower sensitive the th driving state is to the influence of the evaluation indicator. 7, pp. 5, no. Compensation may impact where the Sponsors appear on this website (including the order in which they appear). 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 operational response, which directly lead to increased driving risks [24]. 13, no. 2672, no. Comparison of drivers PARSV for each driving state in different traffic conditions. 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%). 5, pp. Hierarchical clustering results of fixation points. News. This indicator is used to quantitatively characterize the drivers visual stability in different driving states and comprehensively assess the safety level of the drivers state. This report drives home just how devastating traffic crashes are for families and the economic burden they place on society, Ann Carlson, NHTSAs acting administrator, said in a statement. 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. 4, pp. The grey correlation coefficient of different driving states in FFS and CFS. Further normalizing this behavior, 18 states and Washington, D.C., have legalized marijuana for recreational use. 19, no. (2)Determine the reference sequence and comparison sequence. And distracted driving is dangerous, resulting in the deaths of 3,142 people in 2020, according to the NHTSA. 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. 1589815908, 2022. 54, no.

Recent studies suggest that human-like driving behavior emerges from embedding risk in AV motion planning algorithms. The drivers fixation area is divided into six categories of AOIs. While millennials clearly make up the largest percentage of risky drivers, not everyone agrees that bad driving is a millennial problem. Data standardization processing. Percent of Events in which Behavior was Present, Seatbelt use continues to stand out as both a top behavior fleets are actively looking to address and one that drivers continue to struggle with, despite the inherent dangers and risk of policy violations and citations, said Del Lisk, Lytxs vice president of safety services. Driving is a seemingly innocuous part of modern life and, for many, has become second nature. The saccade amplitude of all drivers was counted, as shown in Figure 5. 16, no. 9, pp. 132142, 2017. 28 Apr 2023 20:14:07 We help protect more than 4,800 clients and 1.6 million drivers across the globe. Risky driving behavior No. 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. Throughout June, July and August, Lytx processed more than 15 million driving events captured by its best-in-class, MV+AI-powered DriveCamEvent Recorders. Normalize the information quantity , and the weight of the th evaluation indicator is calculated as follows: Grey correlation analysis is an important part of grey system theory. See www.lytx.com/driver-information. In automated driving, risk describes potential harm to passengers of an autonomous vehicle (AV) and other road users. 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. All Rights Reserved. 9, pp. Follow Lytx in the news and around the world at events and trade shows. According to the grey system theory, the 18 drivers were regarded as a grey system, and the three driving states were taken as the correlation objects, with the VSC as the correlation indicator.

Ali Sharifi, Discrete hartley matrix transform precoding-based OFDM system to reduce the high PAPR, ICT Express, vol. 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. Here, 3D-MAX software was used to build the test scenario to simulate the driving conditions of drivers on urban expressways in clear weather. Advertised example rates are returned based on the driver's self-reported data, by comparing their current reported premium against their new policy premium, and the driver meeting certain criteria. 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. 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. However, the distribution of fixation data collected by the eye tracker is discrete, and the pattern is not obvious. - Lytx advances fleet safety with 15 million event clips captured and processed over a three-month period, - Data reveals drivers not wearing seatbelts and following the vehicle ahead too closely together represent 54% of all coachable incidents captured this summer, SAN DIEGO Sept. 16, 2020 Lytx, a leading global provider of machine vision and artificial intelligence (MV+AI)-powered video telematics safety and productivity solutions for commercial, public sector, and service fleets, experienced a record-breaking summer in terms of the video data it captured, processed and delivered to empower drivers and clients. At this time, the mutual interference between vehicles was obvious, showing the speed adaptation characteristics, and the road was continuously congested. How high-risk drivers can get lower car insurance rates, Speeding can affect your auto insurance rates, Do Not Sell or Share My Personal Information. Change of VSC and grey correlation degree in different traffic conditions and driving states. Meanwhile, speed-related crashes continue, and fatality rates on our roadways continue to increase.. Cell phone call operations during driving can lead to distraction and cause potential safety hazards. The pupil area data of each driver in normal driving under two traffic conditions were averaged, and the pupil area distribution of each driver in the absence of the secondary distraction task is shown in Figure 7. The drivers VSC in the free flow scenario was more sensitive to the impact of cell phone call operation, and the increase in driving risk was greater when driving distracted. There are many factors that induce individual pupil changes. 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]. 166, Article ID 106540, 2022.

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. Learn about the latest in fleet and compliance management through our comprehensive Resource Hub. During the test, the subjects were required to drive the SV to follow the LV in front and keep a certain following distance. Cell phone call operations during driving can lead to distraction and cause potential safety hazards. 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. 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.. But because driving comes so easily, we often forget how dangerous it can be. Drivers can request roadside assistance, identify nearby gas prices, locate discounts, book a hotel or map a route via the AAA Mobile app. 3855, 2021. A recent study found this to be the case, Figure 7 shows that the size and distribution of pupil area varied from person to person. Join a collaborative team dedicated to building technology that helps save lives. 4, pp. According to the calculation results of VSC, the K-means clustering method was used to classify drivers VSC into four categories and determine the interval range of four visual stability types [57]. 124, Article ID 103187, 2022. The captured clips span Lytxs entire client base, including thousands of trucking, distribution, waste, public sector, construction, transit and service fleets. In automated driving, risk describes potential harm to passengers of an autonomous vehicle (AV) and other road users. 366376, 2019. These motorists identified as someone who consumed alcohol and used marijuana in the past 30 days, and in some cases, they may have used both at the same time. 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 83, pp. In the free flow, different types of cell phone call operations had the opposite influence on the IEFA, while the saccade amplitude, PARSV, and RCPA all showed an increasing trend compared to the normal driving state, and the above four types of indicators in congested flow all showed an increasing trend compared to normal driving. AAA encourages drivers to maintain a cool head and focus on reaching their destination safely. Studies have also shown that hands-free calls have no less negative impact on driving performance than hand-held calls [26]. Overall design framework of simulated driving test. Subsequent The results showed that there was statistically significant when divided into four categories (=563.469, =3.8261064), and the results of the cluster analysis are shown in Table 13. 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. 372379, 2007. 45, pp. Some of the major stressors reported included: Watching the behaviours of other drivers, including distracted driving (78 per cent).

WebAvoid the Six Most Unsafe Driving Behaviors unsafe Driving behavior #1: improper speed Remember: For every 10 mph (16 kph) over 50 mph (80 kph), the risk of death in a 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. WebThe purpose of this chapter is to review and critique the literature on risky drinking, driving, and sexual behaviors. 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. The lighter the color, the lower the VSC, the worse the drivers visual stability, and the greater the driving risk. The analysis shows that all kinds of cell phone call operations caused a general decrease in drivers VSC, among which the negative impact of the video call on driving safety was more significant, and the decrease in VSC was significantly higher than that of the hands-free call. Ages 75+: 69.1 percent. The calculation results of the grey correlation degree are shown in Table 14, and the change in the relationship between VSC and correlation degree was drawn in combination with the mean VSC of the drivers, as shown in Figure 13. In summary, most of the current distracted driving research on cell phone operations focuses on traditional call methods. (See abstract). Percentage of VSC in each interval for different traffic conditions and driving states. Here are the NHTSAs consequences of speeding: Speeding can affect your auto insurance rates as well drivers will pay rates of 22% to 30% higher premiums on average following a speeding ticket and these rates could be in effect for three years. There have been many years of evolving policies to reduce the instances of this behavior, and it is a combination of stricter enforcement and serious penalties.. 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. 14, no. 98105, 2019. Considering the indicator variability and conflict, the information quantity of the th evaluation indicator can be calculated by equation (7). K. Tahkoubit, H. Shaiek, D. Roviras, S. Faci, and A.

The specific region division is shown in Figure 2. Since 1902, the not-for-profit, fully tax-paying AAA has been a leader and advocate for safe mobility. A high PAPR of the system is likely to cause signal distortion, which will lead to an increase in the bit error rate (BER) of the system and result in hardware loss and system performance degradation, so it must be suppressed [5052]. The RCPA was mainly distributed from 0.839 to 2.489 in the free flow, and the RCPA was mainly distributed from 0.706 to 1.962 in the congested flow. Prevalence of Self-Reported Impaired Driving Behaviors in Relation to Alcohol and Marijuana Use in a Sample of 2,710 U.S. 2, pp. This value can be used as one of the indicators to measure the stability of the communication system. 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. This results in drivers taking greater accountability over improving their safety and compliance, while immediately reducing risk. Automotive, Travel, and Traffic Safety Information. Anything that takes a driver's attention from the road, including dialing, texting, and adjusting cell phones and other electronic devices, increases the risk of car Some prescription and OTC medicines can cause extreme drowsiness and dizziness. Our mission is to help you make educated insurance decisions with confidence. 112, 2018. Then, based on the improved CRITIC method, the visual stability coefficient (VSC) was constructed as a new indicator to comprehensively assess the risk level of the driving state, and the assessment criteria were divided. Through AAA Foundation research, AAA is working to improve understanding of the topic and work collaboratively with safety stakeholders to reduce the impact of substance-impaired driving-related crashes. With 4/20 approaching, its worth noting that marijuana use can inhibit concentration, slow reaction times, and cloud judgment. The PARSV of all drivers was calculated, as shown in Figure 6, which was mainly distributed from 2.726 to 3.316dB in free flow and 2.851 to 3.352dB in congested flow. About 28 people in the United States die in drunk-driving crashes every day. During the test, the SV in the congested traffic flow needed to maintain a low-speed driving state, allowing overtaking and lane change. Y. Yao, X. Zhao, X. Feng, and J. Rong, Assessment of secondary tasks based on drivers' eye-movement features, IEEE Access, vol. About Lytx From choosing to drive while impaired, and speeding, to driving distracted or running red lights, using these two drugs leads to poor decision-making with potentially fatal consequences.. The distribution of PARSV was similar in the two traffic conditions, and the mean PARSV of drivers in the cell phone operation state was generally increased compared with the normal driving state, and the growth rates of the hands-free call state were relatively low, 2.64% and 0.77% in free flow and congested flow, respectively, while the mean PARSV in video call state increased more, with growth rates of 8.52% and 5.64%, respectively, indicating that the saccade velocity fluctuated greatly and the visual stability decreased during distracted driving. 5, pp. Copyright 2023 Haixiao Wang et al. The simulated cockpit adopted real vehicle control components and was modified from the BYD F3 car. The results showed that cell phone call operation generally had a significant influence on drivers visual information processing patterns, with varying degrees of changes in visual characteristics indicators. The dispersion of saccade amplitude in the two traffic conditions was similar, but the saccade amplitude in the congested flow was significantly lower than that in the free flow under the same driving state. The subjects were asked to complete two secondary tasks of hands-free calls and video calls in two different traffic conditions. 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]. 4: Not using seat belts, Risky driving behavior No. Also, safe driver and other discounts may have been applied to achieve the advertised rate, which may not be available to the average consumer. 2, pp. Lytx connects all the dots to reveal a clear and actionable view of your fleet that helps you and your drivers save time, reduce costs, improve safety, and deliver the very best for your customers.
