Then entered the formal test, and the cell phone was switched to the WeChat interface and placed in the center console of the car. J. Zhang, Y. Wang, and G. Lu, Extended desired safety margin car-following model that considers variation of historical perceived risk and acceptable risk, Transportation Research Record, vol. 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. O. Oviedo-Trespalacios, M. M. Haque, M. King, and S. Demmel, Driving behaviour while self-regulating mobile phone interactions: a human-machine system approach, Accident Analysis & Prevention, vol. While millennials clearly make up the largest percentage of risky drivers, not everyone agrees that bad driving is a millennial problem. WebThe purpose of this chapter is to review and critique the literature on risky drinking, driving, and sexual behaviors. In order to further investigate the interactive influence of traffic conditions and driving states on IEFA, the two-way ANOVA was adopted, as shown in Table 4. 168181, 2021. Due to the intelligent and diversified functions of cell phones, operating cell phones has been one of the main causes of driving distraction [79]. 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. Recent studies suggest that human-like driving behavior emerges from embedding risk in AV motion planning algorithms. 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. Learn how we combine innovation with experience to stand out from the crowd. This results in drivers taking greater accountability over improving their safety and compliance, while immediately reducing risk. Figure 7 shows that the size and distribution of pupil area varied from person to person. 121, Article ID 102319, 2021. 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. 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. 114235114245, 2021.

The calculation equation of indicator conflict is as follows: Calculation of indicator information quantity. The report on the economic impact of crashes also touched on the risky driving behaviors that lead to crashes, fatalities, serious injuries and property damage. Heatmap of drivers VSC in different traffic conditions and driving states. This is due to the increased complexity of the driving environment in the congested flow scenario, where drivers need to pay attention to the changes in the traffic flow in front of them at all times, which makes it more challenging to extract information, reducing the saccade range. 45, pp. M. Wang and J. Zeng, Hierarchical clustering nodes collaborative scheduling in wireless sensor network, IEEE Sensors Journal, 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. 4, pp. 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. In order to explore the individual differences in pupil area, the significance test was performed on the pupil area of the drivers, and the results of one-way ANOVA are shown in Table 9, with significant individual differences in the pupil area of the drivers.
