摘　　要：考虑跟驰过程与换道过程的结合,在车辆换道过程的具体实施过程中引入跟驰模型,以全速度差模型为基础,对换道过程中的换道加速度进行确定,并通过对天津市视频录像换道时间的统计分析,建立了换道距离与换道时车头偏角之间的关系.最后利用Netlogo平台对模型进行了实现与仿真分析,结果表明:该模型很好地体现了实际换道的特点.Considering the combination of car-following model and lane-changing model, we troduced the car-following model during the process of lane-change. Based on FVDM car-following model, the lane-change acceleration is determined. The relationship between lane-change distance and the front wheel turning angle is established by analyzing the actual images of lane change in urban road, Tianjin, China. Finally, the model is implemented by using the platform Netlogo, the effectiveness of the model and rules is illustrated by the computer simulation.
