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. 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. Learn about modern fleet management and get tips and tricks for transforming your fleet. And what compounds these safety challenges, especially at night, are speeding, aggressive driving, distracted driving and impairment from alcohol or drugs. Automotive, Travel, and Traffic Safety Information. 101, Article ID 103692, 2022. In summary, most of the current distracted driving research on cell phone operations focuses on traditional call methods. Fixation area division based on hierarchical clustering of fixation points. 7, pp. They often involve only a single driver (and no passengers) running off the road at a high rate of speed with no evidence of braking. State Council of the People's Republic of China, Regulation on the Implementation of the Road Traffic Safety Law of the People's Republic of China, State Council of the People's Republic of China, Beijing, China, 2017. 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. Considering the safety of drivers and the management regulations of traffic laws, studies on distracted driving by cell phone operation are usually carried out based on the simulated driving devices, and simulated driving tests are carried out by designing different driving environment scenarios to restore the real driving experience [4, 2931]. N. Zhao, B. Reimer, B. Mehler, L. A. A speeding ticket could also result in a driver losing their safe driving discount, increasing your rate. M. I. Santos, P. Oliveira, and A. P. C. Larocca, Investigation the influence of risk factors on the occurrence of road accidents using the driver performance model, Transportation in Developing Economies, vol. Therefore, a single pupil area index cannot accurately reflect the changing pattern of visual load. 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]. 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 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 430443, 2018. This value can be used as one of the indicators to measure the stability of the communication system. 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 larger is, the more information the indicator contains, the greater the importance in the evaluation system, and the higher the weight assigned. 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. Get help with your Lytx solutions through our customer support center. There are many factors that induce individual pupil changes. 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. Around 47% of passengers killed in 2019 in crashes were not wearing seat belts. 711724, 2022. 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. Lytx maintains the fastest-growing proprietary database of professional driving data of its kind, currently surpassing 130 billion miles of driving data. 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. Distracted driving led to 10,546 fatalities, 1.3 million nonfatal injuries and $98.2 billion in economic costs in 2019. 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. Some behaviours that contribute to severe and even fatal injuries in RTCs include failing to wear a seatbelt and being distracted. The simulated cockpit adopted real vehicle control components and was modified from the BYD F3 car. 8697, 2018. 5, pp. Cell phone call operations during driving can lead to distraction and cause potential safety hazards. 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. ( 2012 ) and modified by the author consistent with Indonesian context. 2021, Article ID 6642999, 10 pages, 2021. In contrast, the distribution of RCPA was more discrete in free flow, indicating that RCPA was more sensitive to the influence of the driving state in this traffic condition, and the value fluctuated more. 124, Article ID 103187, 2022. 161165, 2021. This is quite a bold statement, I know, but it is pure science, the science of behavior. The RCPA was introduced into the study of distracted driving, calculated as shown in the following equation:where denotes the RCPA of the driver at time , which is dimensionless, and (mm2) are the pupil area at time and time when the driver is in normal driving, hands-free call, or video call state in the formal test, respectively. Calculate the grey correlation coefficient. Laura is an award-winning editor with experience in content and communications covering auto insurance and personal finance. In automated driving, risk describes potential harm to passengers of an autonomous vehicle (AV) and other road users. 114235114245, 2021. F. You, H. Tu, Y. Gong, H. Wang, and J. Xu, Influence of mobile phone social entertainment operation on driver's visual parameters, Journal of Transportation Systems Engineering and Information Technology, vol. 1: Drunk driving, Risky driving behavior No. 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, , . 3: Distracted driving Risky driving 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. 113, no. Deliver value to your customers by offering smart and simple video dash cam technology.. The study shows that drivers He, and Z. Zhang, Structural multi-objective topology optimization and application based on the criteria importance through intercriteria correlation method, Engineering Optimization, vol. W. Fan, Z. Xu, B. Wu, Y. According to the evaluation criteria of visual stability based on the cluster analysis, the percentage of drivers VSC in each interval for different traffic conditions and driving states is shown in Figure 9. "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. Lytx clients coached 3 million risky driving events this summer. texting), drug use, binge drinking, and risky sexual behavior. 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. L. Ocampo, J. L. Aro, S. S. Evangelista et al., Composite ecotourism potential index based on an integrated stochastic CRITIC-weighted sum method, Current Issues in Tourism, vol. 22, p. 15354, 2022. Risky driving behavior does not have to result in a crash or collision to have serious negative consequences. According to equation (1), the minimum sample size was obtained as 14. Therefore, driving distraction is a major factor affecting the safety of the road traffic system [1416]. John is the editorial director for CarInsurance.com, Insurance.com and Insure.com. Percentage of VSC in each interval for different traffic conditions and driving states. 16, no. Ages 16-18: 69.3 percent. 56, no. A recent study found this to be the case, There were 697 drowsy-driving-related crashes in 2019. L. Qin, Y. Shi, Y. Reduced effectiveness of occupant protection equipment. Considering the indicator variability and conflict, the information quantity of the th evaluation indicator can be calculated by equation (7). Software. By calculating the variation coefficient of each evaluation indicator, the internal variability of the indicator is characterized by the degree of data dispersion. 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]. 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. 1, pp. 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]. Watch our videos to see the latest in driver safety, coaching best practices, risk management and more. Therefore, the hierarchical clustering method combined with the mechanical division method was used to divide the drivers fixation area. 2, p. 2021, 2021. It can be considered that the more orderly the system is, the smaller the information entropy is, and vice versa [46, 47]. The limitation of this study is that the driving risk of distracted states was only assessed in terms of the drivers visual behavior, and the influence of individual attribute characteristics such as the drivers age and driving experience was not considered. Lytxisa leading provider of video telematics, analytics, safety, and productivity solutions for commercial, public sector, and field service fleets. She has written for several media outlets, including the USA Today Network. 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. - 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. 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. 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. Copyright 2023 CarInsurance.com. T. M. Rudisill, H. Chu, and M. T. Zhu, Cell phone use while driving laws and motor vehicle driver fatalities: differences in population subgroups and location, Annals of Epidemiology, vol. Our team is at your service to share custom demos, guide you to the best solutions, or provide support. 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. 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. A. Moustafa, Pupil dilation as an indicator of future thinking, Neurological Sciences, vol. 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. 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. 7177, 2013. Editorial Integrity - Why you should trust us? Then entered the formal test, and the cell phone was switched to the WeChat interface and placed in the center console of the car. This industry-leading, ultra-precise MV+AI triggers in-cab alerts that empower drivers to recognize their own risky driving habits and self-correct in the moment. 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. 13, no. 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. 11, p. 1805, 2016. 26362641, 2016. The decision matrix is constructed as follows: Determine the reference sequence and comparison sequence. 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. Copyright 2023 AAA. 236243, 2020. The saccade amplitude is the range covered by the line of sight from the beginning to the end of a saccade, usually expressed in degrees of view [48]. There were 697 drowsy-driving-related crashes in 2019, according to the NHTSA. However, the influence of this new secondary driving task on drivers visual characteristics is still unclear, and there is a lack of corresponding supervision. 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. 3, pp. Learn about best practices and get solutions to common fleet management challenges. 10, no. 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 You may have wanted to get the work done on time and thought that was a value we needed from you, but I can see the effect of the behavior, and it put people at risk.
