The original data of each evaluation indicator are standardized as follows:The standardized data matrix is constructed, as shown in the following equation:(3)Indicator variability analysis. Comparison of drivers saccade amplitude for each driving state in different traffic conditions. It seems as if this practice has become epidemic. Here's eveything you need to know about the dangers of drink-driving. With more than 160,000 new driving events captured every 24 hours, Lytx clients benefit from the industrys most reliable and expansive data set to help them detect and reduce high-risk driving behaviors. 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%). Furthermore, feature importance analysis was applied to the final. The reason is that in the free flow scenario with a single driving environment, the drivers were in a state of severe cognitive distraction when talking hands-free, and the behavior of observing the surrounding road conditions was significantly reduced. A. R. Mishra, P. Rani, and K. Pandey, Fermatean fuzzy CRITIC-EDAS approach for the selection of sustainable third-party reverse logistics providers using improved generalized score function, Journal of Ambient Intelligence and Humanized Computing, vol. Drivers can request roadside assistance, identify nearby gas prices, locate discounts, book a hotel or map a route via the AAA Mobile app. Editorial Integrity - Why you should trust us? It can be considered that the more orderly the system is, the smaller the information entropy is, and vice versa [46, 47]. This is an open access article distributed under the, Construction of original data matrix. D. Zhang, F. Chen, J. Zhu et al., Research on drivers' hazard perception in plateau environment based on visual characteristics, Accident Analysis & Prevention, vol. 3855, 2021. Risky driving behavior No. D'Ambrosio, and J. F. Coughlin, Self-reported and observed risky driving behaviors among frequent and infrequent cell phone users, Accident Analysis & Prevention, vol. 1: Drunk driving, Risky driving behavior No. "Ultimately, knowing what drives us puts us in the driver's seat. 3 Million Risky Driving Events Analyzed; Top 5 Most Common Risky Behaviors Identified. 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. (5)Calculation of indicator information quantity. 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. The drivers fixation area is divided into six categories of AOIs. And what compounds these safety challenges, especially at night, are speeding, aggressive driving, distracted driving and impairment from alcohol or drugs. 118, pp. Comparison of drivers pupil area during normal driving in different traffic conditions. 454468, 2012. 830846, 2022. Its basic principle is to calculate the grey correlation degree to measure the correlation between sequences by studying the magnitude of correlation between comparison sequence and reference sequence, so as to assist in decision-making, which has the advantages of small calculation and high applicability [3942]. Can you name them all? Therefore, driving distraction is a major factor affecting the safety of the road traffic system [1416]. The effects of distraction on driver situation awareness, Safety Science, vol. 5, pp. where , and the comparison sequence is . From drunk driving to texting behind the wheel, drivers often engage in behaviors that increase their chance of an accident and that can affect their insurance rates. During the test, the subjects were required to drive the SV to follow the LV in front and keep a certain following distance. The test adopted a two-factor design to develop two urban expressway simulation scenarios, free flow and congested flow, for subjects to complete two secondary driving tasks, video call and hands-free call. The specific region division is shown in Figure 2. X. Yang, F. Wang, Y. Wang, T. Zhao, C. Gao, and X. Hu, Are pupils the window of our mind? When drivers are in different degrees of distraction, visual behavioral indicators change correspondingly [32]. Evaluation results of grey correlation analysis method. In addition, the correlation coefficient between indicators may be negative, resulting in errors in the evaluation results. Alcohol creates a sense of false confidence which can lead to risk-taking behaviour behind the wheel. Percentage of VSC in each interval for different traffic conditions and driving states. Drivers in the UAE engage in risky behaviours and they are highly distracted. (2)Determine the reference sequence and comparison sequence. 2020, Article ID 8878265, 14 pages, 2020. In the congested flow scenario (CFS), with the triggering of the traffic flow event, a large amount of traffic flow will appear around the SV and the LV at the same time, both SV and LV were quickly integrated into the traffic flow, and the average speed of the traffic flow was designed to be 35km/h. At present, scholars have conducted some research on the visual characteristics of drivers when distracted by cell phone operations [13, 1720]. Even in small amounts, alcohol can affect a drivers reaction time and driving ability. Drivers should never wait for a warning before taking measures to avoid an accident. Weve led the way for more than 20 years, advancing fleet safety, efficiency, and compliance. During driving, drivers constantly search and process external environmental information through the vision to ensure driving safety. Some behaviours that contribute to severe and even fatal injuries in RTCs include failing to wear a seatbelt and being distracted. This behaviour includes everything from texting to checking emails to driving while under emotional strain, all of which can lead to accidents. Previous research suggests that users who drive high are up to twice as likely to be involved in a crash. Comparison of drivers PARSV for each driving state in different traffic conditions. N. Zhao, B. Reimer, B. Mehler, L. A. Learn about best practices and get solutions to common fleet management challenges. 14, no. A separate NHTSA study put the cost of vehicle crashes at $340 billion, based on 2019 crash data. 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. The maximum value of the data in each row of the decision matrix. 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. 21, no. 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. 2672, no. M. Oliva, Pupil size and search performance in low and high perceptual load, Cognitive, Affective, & Behavioral Neuroscience, vol. There are many factors that induce individual pupil changes. The mean IEFA in the video call state surged compared with the normal driving state, with growth rates of 18.82% and 18.54% in free flow and congested flow, respectively. WebWhat Are Risky Driving Behaviors? texting), drug use, binge drinking, and risky sexual behavior. Y. Sha, J. Hu, Q. Zhang, and C. Wang, Systematic analysis of the contributory factors related to major coach and bus accidents in China, Sustainability, vol. Lytx MV+AI technology is a driver aid only. Difference analysis in pupil area of drivers. 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. AAA opposes the legalization of recreational marijuana because of its inherent traffic safety risks and the difficulties in writing legislation that protects the public and treats drivers fairly. Overall, risky driving behaviors increase the risk of a crash 11 times , while aggressive driving increases risk nearly 35 times ! Firstly, the drivers fixation area was divided into six parts by using the combination of the hierarchical clustering method and mechanical division method. 317325, 2018. The captured clips span Lytxs entire client base, including thousands of trucking, distribution, waste, public sector, construction, transit and service fleets. The IEFA of the drivers in different driving states under two traffic conditions was calculated, as shown in Figure 4. 7, pp. 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. 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. WebKulendranM,PatelK,DarziA,VlaevI.Diagnosticvalidityofbehaviouralandpsychometricimpulsivitymeasures:Anassessmentinadolescentandadultpopulations.PersonalityandIndividualDifferences.2016;90:347352 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. 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. Hardware. 3, pp. The significance level is set to 0.1, then =1.25, and the value range of is between 0.25 and 0.5. Ages 60-74: 67.3 percent. 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. Fees for shipment of hardware may apply. The lighter the color, the lower the VSC, the worse the drivers visual stability, and the greater the driving risk. 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. This is quite a bold statement, I know, but it is pure science, the science of behavior. 8, pp. T. Li, T. Zhang, Y. Zhang, and L. Yang, Driver fatigue detection method based on human pose information entropy, Journal of Advanced Transportation, vol. Speeding is a top contributor to crashes along Americas roadways and is a type of aggressive driving, which has been on the rise. Automotive, Travel, and Traffic Safety Information. This value can be used as one of the indicators to measure the stability of the communication system. WebChronic fatigue symptoms of jobs are risk factors that may cause errors and lead to occupational accidents. Based on the objective weighting of indicators using the improved CRITIC method, the VSC was constructed to quantitatively characterize the visual stability of drivers in different driving states, and the K-means clustering method was used to divide the range of VSC values for four types of visual stability, and to comprehensively assess the safety level of driving states from the perspective of visual psychological safety. Here are the three most common factors in drowsy-driving crashes: NHTSA Distracted Driving Dangers and Statistics, NHTSA Drowsy Driving: How to Avoid Falling Asleep Behind the Wheel, NHTSA Early Estimate of Motor Vehicle Traffic Fatalities for the First 9 Months (JanuarySeptember) of 2022, NHTSA The Economic and Societal Impact of Motor Vehicle Crashes, 2019. Trial services are provided at no cost for up to 1 month. 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. X. Ding, H. Wang, M. Gao, and Z. Lyu, Evaluation and modeling of driver's visual load at entrance and exit of a highway tunnel, Tunnel Construction, vol. 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. WebRT @linda72135856: No ones life should be at risk when simple, honest mistakes are made, e.g., ringing the wrong doorbell, driving into someones driveway, delivering food to the wrong address, etc. 6: Drowsy driving, car insurance rates may increase after a DUI, The Governors Highway Safety Association has a map. 1, p. 5262, 2022. According to the division range of visual stability types, the heatmap of the VSC of each driver in different driving states was drawn, as shown in Figure 10. 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. 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. During the test, the SV in the congested traffic flow needed to maintain a low-speed driving state, allowing overtaking and lane change. 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].

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). 7, pp. 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. They also engage in various other dangerous driving behaviors far more than drivers who consume either just alcohol or abstain from either drinking alcohol or using marijuana. 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. 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. 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. 10, no. 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]. Get help with your Lytx solutions through our customer support center.

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. (6)Calculation of indicator weights. What is a JUA or an assigned risk pool for high-risk driver car insurance? 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. 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]. As a new universal indicator, it can better quantify the level of visual load of drivers and measure visual comfort. Lets pinpoint new behaviors you want to do, so you can see 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 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. W. Li, J. Huang, G. Xie, F. Karray, and R. Li, A survey on vision-based driver distraction analysis, Journal of Systems Architecture, vol. See www.lytx.com/driver-information. Considering the lack of in-depth discussion on the impact of video call operation on drivers driving safety in previous studies, this article designed two typical traffic flow scenarios of free flow and congested flow on urban expressways to carry out a distracted driving simulation test and collected the eye movement data of drivers in three driving states of normal driving, hands-free call, and video call, respectively, and comprehensively considered the characteristics of drivers eye fixation, saccade, and pupil changes to select four visual indicators. 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.

Lytxs scale and enduring commitment to customer-centered innovation has allowed us to create the best edge-detection and alerting technology in the industry, said Brandon Nixon, Lytx chairman and CEO. 56, no. Cell phone call operations during driving can lead to distraction and cause potential safety hazards. 3: Distracted driving Risky driving 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]. Results were adjusted for age, gender, education, and race. The design of the distracted driving simulation test followed the process shown in Figure 1. 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]. The grey correlation analysis method was used to analyze the sensitivity of three driving states affecting VSC under different traffic conditions, whereby the assessment results of driving state risk were further verified. 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.
