Considering the existing overtaking model, currently only calculation of the overtaking time and distance is required for vehicles from their overtaking behavior. However, the decision of the key positions in the overtaking process ignored. Based on the existing overtaking models, this paper proposes the overtaking feasibility decision making ability of key position of overtaking process, as well as lane change decision, and adds the vehicle operating characteristics to form a complete set of different speeds for different vehicles. The model is designed for the purposes of location overtaking feasibility decision, to verify the effectiveness of the established decision model algorithm. The results show that the overtaking time and distance of the two-lane highway are closely related to the vehicle type, overtaking speed, overtaking vehicle, speed of the overtaking vehicle and the speed of the opposite vehicle. In consideration of the moving characteristics of the vehicle, different vehicles need to overtake, and the overtaking time and distance are different, and multiple decisions are made at key positions in the vehicle overtaking process. The experimental results show that the obtained results are significantly in line with the actual overtaking phenomenon.
