摘要:

现有对车道变换过程进行的研究,一般集中在变道车辆进入目标车道以后的 过程.基于NGSIM数据发现,在半过渡期,目标车道后车的驾驶行为同时受到本车道前车 和变道车辆的双重影响.针对此,本文把车道变换过程分为4 个阶段,然后把共同组成过 渡期的半过渡期和松弛期区别开来,单独对变道车辆进入目标车道之前的过程进行分析. 同时,引入了随变道车辆横向位移的变化而不断变化的关注度平衡因子,对现有的变道 模型进行了完善,以期准确把握车道变换对目标车道后车的影响.最后,利用车辆轨迹线 法对模型进行校检,模型校检结果标准误差和平均绝对百分比误差都充分体现了此模型 的合理性和优越性.

Abstract:

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.

Key words: traffic engineering, lane changing behavior, NGSIM data analysis, lane changing model, half transition period
