Analyzing the Impact of Traffic Violation Behaviors on Traffic Fatal Crashes Using Multilevel Models on Expressways

Abstract

This study is intended to explore the impact of traffic violation behaviors on traffic fatal crashes on expressways. Based on the generalized additive model method, for independent traffic violation data and traffic fatal crash data from the Traffic Administration Bureau of Anhui Provincial Public Security Department, the relationship among the violations and traffic fatal crashes was discussed. Applying the proposed multilevel analysis method, which can effectively show the evolution trend among traffic violations and traffic fatal crashes influenced by time, space, and inter-reaction. The results show that hierarchical data structures should not be ignored. Meanwhile, in order to avoid fatal traffic collisions, we should reduce traffic violations, especially the control of speed on expressways This is because speeding is the most common traffic violation behavior and has a significant impact on traffic fatal crashes. The results could help strengthen our focus on key traffic violations and provide a reference for traffic safety management and decision-making.
