Speeding is a top contributor to crashes along Americas roadways and is a type of aggressive driving, which has been on the rise. Copyright Lytx, Inc, 2023. This indicates that when the drivers were in the distracted driving state, the visual cognitive resources were occupied to different degrees, and the driving load increased, so they could not effectively obtain road information and needed to adopt the compensatory behavior of expanding the saccade amplitude to adapt to the surrounding environment to ensure driving safety. Drivers, Weighted to Represent U.S. Driving Population Ages 16 and Older. In the two traffic conditions, the mean VSC of drivers in the cell phone operation state generally decreased compared to the normal driving state, with a lower decrease rate in the hands-free call state, 4.80% and 2.86% in free flow and congested flow, respectively, while the decrease rates of the mean VSC in video call state reached 28.46% and 25.05%, respectively, further indicating that the impact of video call operation on drivers driving safety is significantly higher than that of hands-free call. There were 697 drowsy-driving-related crashes in 2019. 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. 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. In order to quantitatively characterize the influence of cell phone call mode on the drivers visual behavior in different traffic conditions and to analyze the risk level of distracted driving from the visual level, a distracted driving simulation test was carried out based on a driving simulator and eye tracker. K. Tahkoubit, H. Shaiek, D. Roviras, S. Faci, and A.

Learn how to avoid unnecessary arguments and recognize the triggers which may result in aggressive or risky behaviors. Learn about the latest in fleet and compliance management through our comprehensive Resource Hub. In automated driving, risk describes potential harm to passengers of an autonomous vehicle (AV) and other road users. However, the distribution of fixation data collected by the eye tracker is discrete, and the pattern is not obvious. 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]. Visual stability evaluation criteria based on cluster analysis. 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. 20, pp. Lets pinpoint new behaviors you want to do, so you can see He, and Z. Zhang, Structural multi-objective topology optimization and application based on the criteria importance through intercriteria correlation method, Engineering Optimization, vol. It can be considered that the more orderly the system is, the smaller the information entropy is, and vice versa [46, 47]. where , and the comparison sequence is . Meanwhile, speed-related crashes continue, and fatality rates on our roadways continue to increase.. WebThe present study aimed the adaptation of the Driving Log, a questionnaire that assesses aggressive and risky driving behaviors in a day by day basis, with 395 Spanish participants. The subjects had relatively free operation rights such as acceleration, deceleration, and braking, but were not allowed to overtake the LV. They also are far more likely to report driving under the influence of alcohol than those who consume only alcohol and not marijuana. Normalize the information quantity. 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. 2, pp. 7, pp. Set objects to be evaluated and evaluation indicators to form the original indicator data matrix as follows:where denotes the original data of the th evaluation indicator of the th evaluation object. 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. Section 3 introduces the concepts and analysis steps of the improved CRITIC weighting model and the grey correlation analysis method. 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]. Join a collaborative team dedicated to building technology that helps save lives. 1, pp. D'Ambrosio, and J. F. Coughlin, Self-reported and observed risky driving behaviors among frequent and infrequent cell phone users, Accident Analysis & Prevention, vol. 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. 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. 23, no. Therefore, the test recruited 18 nonprofessional drivers as subjects, aged from 24 to 51years (mean value is 33.2, and the standard deviation is 9.8). (4)Calculate the grey correlation degree. 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.

She has written for several media outlets, including the USA Today Network. All rights reserved. However, the influence of this new secondary driving task on drivers visual characteristics is still unclear, and there is a lack of corresponding supervision. 2, pp. In contrast, most drivers were in a state of visually distracted during the video call, the driving load surged, so the search range needed to be expanded for safety compensation. 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. 26, pp. The simulated cockpit adopted real vehicle control components and was modified from the BYD F3 car. 454468, 2012. 17, 2018. 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. 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.
