Section 2 describes in detail the design content of the distracted driving simulation test. 98105, 2019. It seems as if this practice has become epidemic. The calculation results of the grey correlation coefficient under two traffic conditions are shown in Figure 12. Behavior With its advanced MV+AI technology, Lytx cuts through the noise and delivers only the most actionable insights with significance for each individual fleet. The original data of each evaluation indicator are standardized as follows: The standardized data matrix is constructed, as shown in the following equation: Indicator variability analysis. 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]. AAA encourages drivers to maintain a cool head and focus on reaching their destination safely. Furthermore, the mean RCPA of the video call increased sharply, with growth rates of 47.69% and 72.75%, respectively. 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. Considering the indicator variability and conflict, the information quantity, Calculation of indicator weights. With the continuous innovation and development of intelligent terminals and communication technologies, the equipment of various electronic devices in the car provides convenience and simultaneously makes the potential sources of distraction for drivers continue to grow, and the demand for multitasking significantly increases [5, 6]. The IEFA of the drivers in different driving states under two traffic conditions was calculated, as shown in Figure 4. Weve led the way for more than 20 years, advancing fleet safety, efficiency, and compliance.

She most recently worked in the public sector for the Nevada Department of Transportation. Hardware. + Estimate based upon select sampling of Lytx client data. Section 3 introduces the concepts and analysis steps of the improved CRITIC weighting model and the grey correlation analysis method. API integrations. 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 test consisted of a pretest and a formal test. Percentage of fixation point offset distance in each interval for different traffic conditions and driving states. 9, pp. The increase in the number of U.S. drivers engaging in risky driving behavior is troubling, said Morgan Dean, public and government affairs manager at AAA Mid-Atlantic. Fees for shipment of hardware may apply. According to the NHTSA, about 28 people in the United States die in drunk-driving crashes daily. "Ultimately, knowing what drives us puts us in the driver's seat. Therefore, the number of clusters selected in the hierarchical clustering process of the fixation point coordinates was six, and the clustering results are shown in Table 2. With the popularization of smartphones and the update of communication software functions, video chatting is becoming increasingly popular. 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. Finally, the grey correlation analysis was used to quantify the sensitivity of three driving states affecting VSC under different traffic conditions, and the correlation degrees of different driving states were consistent with the variation rule of mean VSC, which further verified the validity of VSC on the risk assessment results of driving states. 3, pp. 4, 7 Often, several of these risk factors are present: In particular, teens who text while driving are more likely to have other risky driving behaviors as well, compared to those who don't text while driving. Table 2. 317325, 2018. Firstly, the drivers fixation area was divided into six parts by using the combination of the hierarchical clustering method and mechanical division method. 1, pp. 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. Risky Driving Behaviors See www.lytx.com/driver-information. Driving Risk proposed the concept of relative change intensity of pupil area (RCPA) based on the characteristics of visual load oscillation, that is, the ratio of the amount of pupil area change in two driving environments indicates the fluctuation amplitude of visual load [56]. Drivers psychological effort increased, their psychological and physiological load increased, and their visual adaptability decreased, resulting in pupil dilation. 161165, 2021. Stay Cool. Even in small amounts, alcohol can affect a drivers reaction time and driving ability. 2, pp. Driving Behaviors Risky traffic behavior includes participation in illegal high-speed competitions (street racing), driving without driving license or ignoring traffic police signals, non-compliance with traffic legislation, and alcohol abuse in various social situations, indirectly linked to driving ( Meinhard, 2019 ). Figure 7 shows that the size and distribution of pupil area varied from person to person. 5 Risky Distracted Driving Behaviors | U.S. News According to statistics for fatigue driving, it was found that fatigue driving is one of the Can you name them all? Deliver value to your customers by offering smart and simple video dash cam technology.. The saccade amplitude of all drivers was counted, as shown in Figure 5. Do Distraction, Emotion, and Other Unsafe Behaviors Software. Risk WebChronic fatigue symptoms of jobs are risk factors that may cause errors and lead to occupational accidents. Since 1902, the not-for-profit, fully tax-paying AAA has been a leader and advocate for safe mobility. There were significant differences in RCPA among drivers in different driving states under different traffic conditions. Comparison of drivers VSC for each driving state in different traffic conditions. But because driving comes so easily, we often forget how dangerous it can be. 1, p. 5262, 2022. If you are convicted of a DUI, you may lose your driving privileges and your auto insurance policy could be canceled. R. Saha, M. T. Tariq, M. Hadi, and Y. Xiao, Pattern recognition using clustering analysis to support transportation system management, operations, and modeling, Journal of Advanced Transportation, vol. Therefore, this article was designed to simulate driving in two traffic conditions of free flow and congested flow on urban expressways and to collect eye movement indicators under two driving conditions of hands-free and video call, in order to explore the visual behavior characteristics of drivers during distracted driving, quantify the risk of driving behavior, and provide the theoretical basis for drivers visual behavior correction and driving safety. Risky driving behavior was measured the Behavior of Young Novice Drivers Scale (BYNDS), developed by Scott-Parker et al. Pupil-related application in psychology and pupillometry, Advances in Psychological Science, vol. 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 As a new universal indicator, it can better quantify the level of visual load of drivers and measure visual comfort. 12, no. 7, pp. (2)Data standardization processing. Finally, Section 6 provides an overview discussion of the research results and suggests further research directions. 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. 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. Combined with the results of the sampling survey, set =0.3 and set =10%. 1589815908, 2022. The effects of distraction on driver situation awareness, Safety Science, vol. The maximum value of the data in each row of the decision matrix. Your actual quoted rate may vary greatly and may be subject to adjustment based on verification of your self-reported data. 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. Cell phone call operations during driving can lead to distraction and cause potential safety hazards. The clustering analysis method can gradually improve the clustering effect through several iterations and applies to large sample data [44], so it is suitable for the division of the fixation region. 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. 28, no. Risk The subjects were ensured to have a normal diet and rest without alcohol or drugs for 24h before the test while avoiding strenuous exercise. Change of VSC and grey correlation degree in different traffic conditions and driving states. Alcohol, marijuana, and other drugs slow coordination, judgment and reaction times. Among them, the hierarchical clustering method has the advantages of easy discovery of hierarchical relations between clusters and flexible implementation [45]. Visual stability evaluation criteria based on cluster analysis. N. M. Yusoff, R. F. Ahmad, C. Guillet, A. S. Malik, N. M. Saad, and F. Merienne, Selection of measurement method for detection of driver visual cognitive distraction: a review, IEEE Access, vol. Heatmap of drivers VSC in different traffic conditions and driving states. Some behaviours that contribute to severe and even fatal injuries in RTCs include failing to wear a seatbelt and being distracted. Communication: The Key to Understanding Behaviors By calculating the variation coefficient of each evaluation indicator, the internal variability of the indicator is characterized by the degree of data dispersion. Copyright Lytx, Inc, 2023. According to equation (1), the minimum sample size was obtained as 14. 45, pp. Also, safe driver and other discounts may have been applied to achieve the advertised rate, which may not be available to the average consumer. Our websites do not, and are not intended to, provide a comprehensive list of all companies that may provide the products and services you are seeking. If the acquisition of visual information is missed or deviated, distractions, errors in judgment, and other abnormal situations will inevitably occur, which can easily cause traffic accidents [13]. 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. Streamline compliance for drivers and fleet managers to keep your fleet productive and safe. 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. 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). D. Zhang, F. Chen, J. Zhu et al., Research on drivers' hazard perception in plateau environment based on visual characteristics, Accident Analysis & Prevention, vol. Further normalizing this behavior, 18 states and Washington, D.C., have legalized marijuana for recreational use. 253262, 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. 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 road length was 20km, the lane width was 3.5m, and the speed limit was 80km/h. ( 2012 ) and modified by the author consistent with Indonesian context. Therefore, driving distraction is a major factor affecting the safety of the road traffic system [1416]. risky 128, no. Archived - Safer Roads campaign highlights too many fatalities This is quite a bold statement, I know, but it is pure science, the science of behavior. WebWhat Are Risky Driving Behaviors? Considering the indicator variability and conflict, the information quantity of the th evaluation indicator can be calculated by equation (7).
