To improve the safety of the exit-ramp area of three-dimensional composite expressways, this paper studies the impact of different traffic signs on drivers’ decision-making response and behavior choice from the perspective of drivers based on driving simulator. A total of 32 drivers participated in this experiment. The speed, standard deviation of speed, acceleration, acceleration standard deviation, lateral position and steering wheel angle were used as indicators of the response characteristics of drivers. By paired t-Test, this paper explored the significance of various indicators, and then get the impact of different traffic sign information on driver behavior. The results show that different traffic signs have different effects on driving behavior. Setting direction separation information at the exit of interchange is helpful to promote drivers to change lanes in advance. The research results provide guiding suggestions for improving the overall level of road traffic safety and optimizing the information giving mode of complex interchanges.
