The variables involved in the test are shown in Table 1. 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. 19, no. D. Kong, X. Zheng, Y. Yang, Y. Zhang, and T. Jiang, A novel DFT-based scheme for PAPR reduction in FBMC/OQAM systems, IEEE Wireless Communications Letters, vol. 6, pp. The simulated cockpit adopted real vehicle control components and was modified from the BYD F3 car. It can be considered that the more orderly the system is, the smaller the information entropy is, and vice versa [46, 47]. Note: Percentages include responses of a few times, fairly often, or regularly., * DUI refers to self-reported driving under the influence, not being charged with a DUI by law enforcement. 2: Drug-impaired driving, Risky driving behavior No. (b) CFS. By calculating the correlation coefficient between evaluation indicators and taking the absolute value, the conflict between indicators is measured. 295311, 2022. The captured clips span Lytxs entire client base, including thousands of trucking, distribution, waste, public sector, construction, transit and service fleets. In the free flow scenario (FFS), there were only two vehicles on the lanes in the direction of travel, the subject vehicle (SV) and the leader vehicle (LV), and no other vehicles interfered. As alcohol is ingested, it passes into the bloodstream and accumulates before the liver metabolizes it. Overall, risky driving behaviors increase the risk of a crash 11 times , while aggressive driving increases risk nearly 35 times ! Each operation lasted about the 50s, with an interval of 5min for the subjects to adjust their state. Our customizable services and programs span driver safety, risk detection, fleet tracking, compliance, and fuel management. Both hand-held and hands-free calls put drivers in a state of cognitive distraction [21, 22], where consciousness is diverted from the main driving task, the proportion of forward vision increases, and the information processing speed and the allocation of visual attention are affected, thus weakening the ability to detect the surrounding environment [2325]. 3, pp. 8697, 2018. About the Data Drivers, Weighted to Represent U.S. Driving Population Ages 16 and Older. 3, pp. This results in drivers taking greater accountability over improving their safety and compliance, while immediately reducing risk. Stress and Emotional Strain While not often discussed in correlation with driving, stress and emotional strain can have a major impact on decision-making, reaction time and situational awareness. Risky Driving Behaviors Trial services are provided at no cost for up to 1 month. 114235114245, 2021. Firstly, four visual characteristics indicators that were highly sensitive to traffic conditions and driving states were selected in terms of visual field range, visual recognition, visual search, and visual load, which were the information entropy of fixation area (IEFA), saccade amplitude, peak-to-average ratio of saccade velocity (PARSV), and relative change intensity of pupil area (RCPA). 63, pp. In order to address the influence of individual differences in the pupil area of drivers, Ding et al. 101, Article ID 103692, 2022. 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]. 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. 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. Y. Wang, S. Bao, W. Du, Z. Ye, and J. R. Sayer, Examining drivers' eye glance patterns during distracted driving: insights from scanning randomness and glance transition matrix, Journal of Safety Research, vol. John is the editorial director for CarInsurance.com, Insurance.com and Insure.com. 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. The urban expressway scenario was developed for the simulated driving test to collect eye movement data when the drivers were in different driving states during driving to provide data support for the subsequent analysis of the drivers' visual characteristics. For instance, occupational injuries and traffic accidents stem from overlooking long-term fatigue. Copyright 2023 CarInsurance.com. All rights reserved. 494500, 2019. 3643, 2013. Y. Gao, W. Liu, X. Wang et al., Comparative phytotoxicity of usnic acid, salicylic acid, cinnamic acid and benzoic acid on photosynthetic apparatus of Chlamydomonas reinhardtii, Plant Physiology and Biochemistry: Plant Physiology and Biochemistry, vol. 16831706, 2020. (2)Data standardization processing. The concept of PAPR was introduced into the study of human visual characteristics, and the peak-to-average ratio of saccade velocity (PARSV) was established to reflect the dynamic balance degree of saccade behavior and to represent the stability of individual visual search ability, as defined in the following equation:where PARSV (dB) denotes the peak-to-average ratio of saccade velocity, denotes saccade peak velocity, is the saccade average velocity. With its advanced MV+AI technology, Lytx cuts through the noise and delivers only the most actionable insights with significance for each individual fleet. 2672, no. 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. 113, 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. 7, pp. 16, no. A speeding ticket could also result in a driver losing their safe driving discount, increasing your rate. "This powerful combination of real-time alerts and escalation options for hands-on coaching via our best-in-class Driver Safety Program creates a positive experience that makes it fast and easy for drivers to improve their own performance, while giving management the data-driven reports they need to monitor progress and intervene if needed., Nixon continued, For more than 20 years, weve been designing our products and services to offer the best and most flexible video solutions available to fleet and drivers, whether theyre seeking in-cab risk alerting for driver self-correction or our full driver coaching workflow for manager escalation. Traffic crashes are deadly and impose an enormous financial strain on American society. 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. 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. 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. The road length was 20km, the lane width was 3.5m, and the speed limit was 80km/h. In order to ensure the comparability of test data, two traffic scenarios of free flow and congested flow were set up, both of which adopted a two-way four-lane design. 161165, 2021. Intentional red-light running (48%) vs alcohol-only (32%) Texting while driving (40%) vs. alcohol-only (21%) Unsurprisingly, the study found drivers who neither Subsequent This is quite a bold statement, I know, but it is pure science, the science of behavior. This is an open access article distributed under the, Construction of original data matrix. 14, no. The decision matrix is constructed as follows: Determine the reference sequence and comparison sequence. Avoid the Six Most Unsafe Driving Behaviors 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 The calculation equation of indicator conflict is as follows:where denotes the conflict of the th indicator, and denote the mean values of the th and th evaluation indicators, respectively, and denotes the Pearson correlation coefficient. Risk The NHTSA says alcohol level is measured by the weight of the alcohol in a specific volume of blood, which is called Blood Alcohol Concentration, or BAC. The VSC of all drivers was counted, as shown in Figure 11, and the VSC was mainly distributed from 0.309 to 0.728 in free flow and from 0.288 to 0.686 in congested flow. The pretest did not involve any arrangement of secondary driving tasks, and the SV was in a free driving state that was not affected by the road speed limit and other vehicles. Deliver value to your customers by offering smart and simple video dash cam technology.. She most recently worked in the public sector for the Nevada Department of Transportation. 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]. 10, p. 6241, 2022. 10291041, 2020. 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.. The distance from the fixation point coordinates to the centroid was divided into five intervals with a step size of 100px, and the information entropy calculation equation is shown as follows:where (bits) denotes the information entropy of fixation area (IEFA), is the percentage of the distance of the fixation point offset centroid in the th distance interval when the driver is in type driving state, , when , , is the number of intervals divided by distance, here . Risky 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 Learn about modern fleet management and get tips and tricks for transforming your fleet. Confirmatory factor analysis showed that the questionnaire fitted properly in two correlated factors, labeled as Risky Driving and Aggressive Driving. The calculation equation of indicator conflict is as follows: Calculation of indicator information quantity. 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 traffic deaths on the rise, psychologists are being called on P. Hancock, M. Mouloua, and J. Senders, On the philosophical foundations of the distracted driver and driving distraction, Driver Distraction, Taylor & Francis, Abingdon, UK, 2008. When someone is drink-driving, their reaction time is much slower and their ability to judge speed is signifiactly affected, which can increase the risk of a car accident. Compensation may impact where the Sponsors appear on this website (including the order in which they appear). With each new video clip reviewed and processed, Lytxs AI algorithms become even more nuanced and accurate in identifying high-risk driving behaviors in real time, enabling a safer and more productive future for fleets and drivers alike. 3: Distracted driving, Risky driving behavior No. 20, pp. This Foundation research was published in January 2021 in the peer-reviewed journal Transportation Research Record.

He et al., ID-YOLO: real-time salient object detection based on the drivers fixation region, IEEE Transactions on Intelligent Transportation Systems, vol. Manage driver vehicle inspection reports toensure vehicles are in top working order.. 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. Just like off base, erratic behavior such as changing lanes without use of a turn signal, weaving in between traffic, running red lights, driving on the shoulder, and not stopping while a pedestrian is in the crosswalk are prohibited and can result in your driving privileges being suspended or revoked. While millennials clearly make up the largest percentage of risky drivers, not everyone agrees that bad driving is a millennial problem. 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. AAA provides more than 61 million members with automotive, travel, insurance and financial services through its federation of 32 motor clubs and more than 1,000 branch offices across North America. Do Distraction, Emotion, and Other Unsafe Behaviors Set. Considering the complexity of distracted driving, future comparative studies should be attempted in other road scenarios, combining individual driver attribute characteristics and multiple dimensional indicators such as ECG, EEG, and head movement to comprehensively consider the risk level of distracted driving states. 45, pp. P.

Furthermore, feature importance analysis was applied to the final. Distracted driving is another risky behavior. 5, no. Laura is an award-winning editor with experience in content and communications covering auto insurance and personal finance. While there are specific penalties for driving at very high speeds, typically referred to as reckless driving, there is absolutely not the level of policy and penalties as there are for impaired driving, Morrissey says. 1, pp. Safe roads are 7, no. In fact, risky behavior associated with bad driving was found alarmingly prevalent among all age groups in the study. The maximum value of the data in each row of the decision matrix is selected to form the reference sequence, as shown in equation (10). Difference analysis in pupil area of drivers. Further normalizing this behavior, 18 states and Washington, D.C., have legalized marijuana for recreational use. Risk Assessment of Distracted Driving Behavior Based on Visual 56, pp. More than 50% of drivers involved in serious injury and fatal crashes tested positive for at least one drug, the NHTSA says. Based on the improved CRITIC method, the weights of visual characteristics indicators in the two traffic conditions were calculated, respectively, and the calculation results are shown in Table 12. She has written for several media outlets, including the USA Today Network. 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. T. Li, T. Zhang, Y. Zhang, and L. Yang, Driver fatigue detection method based on human pose information entropy, Journal of Advanced Transportation, vol. Among them, the hierarchical clustering method has the advantages of easy discovery of hierarchical relations between clusters and flexible implementation [45]. The equipment consisted of a simulated cockpit, a scenario display equipment, and an operation control platform. 2022, Article ID 7213814, 15 pages, 2022. Stay Cool.

In order to make the simulation scenarios more realistic, all scenarios were set up with a small number of vehicles randomly appearing in the opposite lanes, but with no effect on vehicles in the direction of travel. Comparison of drivers IEFA for each driving state in different traffic conditions. Drivers in the UAE engage in risky behaviours and they are highly distracted. K. Leighton, S. Kardong-Edgren, T. Schneidereith, and C. Foisy-Doll, Using social media and snowball sampling as an alternative recruitment strategy for research, Clinical Simulation in Nursing, vol. 6328863302, 2019. 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. The National Highway Traffic Safety Administration (NHTSA) has identified six risky driving behaviors. 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. The significance level is set to 0.1, then =1.25, and the value range of is between 0.25 and 0.5. 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. Risk 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. By calculating the variation coefficient of each evaluation indicator, the internal variability of the indicator is characterized by the degree of data dispersion. Communication: The Key to Understanding Behaviors The results show that different cell phone call modes increased driving risk in both traffic conditions. 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 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. WASHINGTON, D.C. (April 13, 2021) People who use both alcohol and marijuana are some of the most dangerous drivers on the road they are significantly more likely to speed, text, intentionally run red lights, and drive aggressively than those who dont, according to data from the AAA Foundation for Traffic Safety. They occur most frequently between midnight and 6 a.m. or late afternoon. In automated driving, risk describes potential harm to passengers of an autonomous vehicle (AV) and other road users.
