The existing research about the process of lane changing is generally focused on the process after the vehicle enters the target lane. Based on NGSIM data, behavior of the rear vehicle on the target lane is influenced by both the front vehicle and the lane changing vehicle during the half transition period. For this,the lane changing process is divided into four stages in this paper, and the half transition period and relaxation period are distinguished, to analysis the process before the vehicle enters the target lane. Besides,in order to accurately grasp the effect of lane changing on the rear vehicle, attention balance factor changing with the lateral alteration of the vehicle is introduced. At last, the model is checked by the method of vehicle trajectory, and the results of Std. Error and MAPE fully reflect the rationality and superiority of the model.
