Abstract: There are many different factors to influence the lane-changing behavior，such as the diversity，randomicity and hardness of measurement of the influence factors.It’s hard to reflect the uncertainty of driver’s lane-changing behavior accurately.The above reason is one great reason for the study of lane-changing models dropped behind the car-following models.On the basis of analysis for the driver’s psycho-physic characteristic，AHP method is used to quantify the hierarchy of driver’s dynamic decision-making process.The lane-changing decision-making model based on AHP method is established.The algorithm is feasible through the field data test.
