With the advent of the “Internet Plus” era and the rapid development of information technology,the penetration rate of smart phones has become higher and higher,and the phenomenon that drivers use smart phones while driving can be seen everywhere.However,the use of mobile phones can lead to distracted drivers.It has brought great hidden dangers to driving safety.Driving safety is a long-term cumulative result.In order to solve the current lack of quantitative and continuous impact analysis of smart phone use behavior on driving safety and the segmentation variables in smart phone use behavior,the paper describes and explains the process of driving safety impact.Several aspects of research:1.On the basis of summarizing existing researches on the use of mobile phones,driving behaviors and the impact of mobile phone use on driving safety,combined with the continued impact of mobile phone use on driving safety,a systematic description of the classification of the use of smart phones and the definition of driving reliability is provided.Based on the driving behavior information processing mechanism and attention distribution theory,the influence process of smart phone usage behavior on driving reliability is analyzed.2.From the perspective of attention allocation under driving behavior,the effects of smart phone use behaviors,driver mental characteristics on sub-task vision,and cognitive resource consumption were constructed,as well as the impact of sub-task visual and cognitive resource consumption on driving unreliability,including Seven latent variables of smartphone use behaviors have a structural equation model that influences driving reliability.A questionnaire on the use of smart phone use behavior in driving safety was designed,and a combination of on-line and off-line vehicle surveys was used to collect 252 valid questionnaires.Through confirmatory factor analysis,the measured values of each latent variable were better.Internal consistency and reliability indicators are acceptable;the measurement of each variable has sufficient aggregation validity.3.An empirical analysis of the impact of smart phone usage behavior on driving reliability based on survey data.The results show that the sub-task visual resource consumption and sub-task cognitive resource consumption have a direct positive effect on driving unreliability,affecting the total effect of 0.542,0.256,respectively,in which sub-task visual resource consumption also affects cognitive resources consumption of sub-tasks.There is an indirect positive impact on driving unreliability;information input and display viewing,voice calls,and psychological features have a direct positive effect on sub-task visual resource consumption and sub-task cognitive resource consumption;information input,display viewing,and voice calls The effect of the three types of smart phone use behavior on driving unreliability was 0.261,0.667,and 0.025,respectively,demonstrating that smart phone use behavior has a significant impact on driving safety.Finally,according to the gender and driving age groups,the positive effect of the use of smart phones on the unreliability of driving of male groups is higher than that of female groups;the positive effect of the use behavior of group smartphones with driving age of more than 3 years on the unreliability of driving.The impact is higher than the three years of driving experience.
