Abstract: There is a high correlation between the use of smartphones while driving and the incidence of traffic accidents. Mobile phone use behavior will lead to drivers' distraction, affect their disposal judgment and road analysis and other abilities, thus bringing huge hidden dangers to driving safety. Based on the information processing mechanism and attention allocation theory of driving behavior, this paper analyzes the influence process of mobile phone use behavior on driving reliability from the aspects of visual resource consumption and cognitive resource consumption of mobile phone use behavior. The results show that in the process of driving, drivers' use of mobile phones occupies visual and cognitive resources of driving behavior, which leads to a decrease in the processing speed of driving information, thus leading to a decline in driving performance and a negative impact on driving reliability.
