Abstract: To study the influence of a change in the traffic management policy on vehicle defective lane-changing behavior, a hypothetical model of SD for vehicle defective lane-changing behavior was built, including subsystems of human, vehicle, road, environment and traffic management policy. Based on the actual survey data, the feasibility analysis of hypothetical model was carried out by using AMOS software. On this basis, a complete SD model of vehicle defective lane-changing behavior was constructed. Finally, the SD analysis software VENSIM was used to simulate the model, and the dynamic influence sequences of the factors in the system on the defective lane-changing behavior of vehicles were explored. The results show that the subsystems of human, vehicle, road and environment will be regulated accordingly, and the defective lane-changing behavior of vehicles will be weakened to varying degrees by adjusting the traffic safety policy, including law enforcement intensity, timely law enforcement rate, the number of safety inspectors and the learning ability of trainers, and that the interactions between the factors make the evolution process of defective lane-changing behavior have several stages.

Key words: defective lane-changing behavior, influencing factors, system dynamics (SD), traffic safety policy, simulation
