All rights reserved. 119, pp. 4, pp. Compared with the normal driving state, the correlation coefficients of drivers in cell phone calls showed different degrees of decrease, and the correlation coefficients in the video call state decreased sharply, and the values fluctuated significantly. Risky Driving Behaviors 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 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. 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. 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. 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. 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. Texting is the largest culprit sending or receiving a text takes a drivers eyes off the road for five seconds, which, at 55 mph, is like driving across a football field with your eyes closed. 54, no.

The equation for calculating the variation coefficient of the indicator is as follows:where denotes the variation coefficient of the th evaluation indicator, is standard deviation, and is the mean value. 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. In the traditional CRITIC method, the variability of indicators is represented by standard deviation, and the larger the standard deviation of data, the stronger the variability is represented and the higher the weight is assigned; the conflict of indicators is quantified by the correlation coefficient, and the larger value of the correlation coefficient between indicators, the smaller the conflict, and the more overlapping information the indicators contain, the lower the weight is assigned [3438]. 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. In addition, the existing research results focus on the visual recognition characteristics of drivers distracted by operating cell phones in a single traffic condition of the same road type, with few studies carried out under different traffic conditions.

These insights were derived from the more than 3 million event clips captured by Lytx MV+AI-powered DriveCam Event Recorders and coached by its clients throughout June, July and August 2020. The grey correlation coefficient of different driving states in FFS and CFS. More than 50% of drivers involved in serious injury and fatal crashes tested positive for at least one drug. WebWhat Are Risky Driving Behaviors? Combined with the mechanical division method, the fixation area was divided into six parts, in which: A is the left rear view mirror; B is the road ahead, which is the main focus area during driving; C is the distant areas of the road ahead; D is the vehicle dashboard area; E is the cell phone placement area of the central console; and F is the right rear view mirror. K. Tahkoubit, H. Shaiek, D. Roviras, S. Faci, and A. Ali-Pacha, Generalized iterative dichotomy PAPR reduction method for multicarrier waveforms, IEEE Access, vol. Younger people were more likely distracted, while older drivers were more likely to have higher depression scores. 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]. 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. Driving Behaviors 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.

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. 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. Ages 75+: 69.1 percent. Visual stability evaluation criteria based on cluster analysis. and (mm2) are the pupil area at time and time when the driver is in the free driving state which is not affected by the road speed limit and other vehicles in the pretest, and is the sample size taken in the 30s data window of the pretest. A recent study found this to be the case, She has written for several media outlets, including the USA Today Network. At this time, the mutual interference between vehicles was obvious, showing the speed adaptation characteristics, and the road was continuously congested. The one-way ANOVA was conducted on the saccade amplitude, and as shown in Table 5, the differences in saccade amplitude in different driving states under different traffic conditions were significant. 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. The test consisted of a pretest and a formal test. The analysis of the impact of cell phone call operations on driving safety was combined with the demand for driving attention due to the complexity of traffic conditions and also provided scenario modeling experience for studies related to distracted driving behavior. 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.
