Abstract: A discretionary lane changing model is constructed by agent theory. Our works analyze the mechanism of motor vehicle’s discretionary lane changing demand from the point of view of microcosmic layer in detail, and propose integrate estimate method based on driving satisfaction of lane. By analyzing the track of vehicle’s lane changing and the span of lane changing, we establish the relation between velocity and angle of lane changing. At last this model is implemented by agent class under the condition of VC.NET.

摘要： 本文利用Agent理论对实际交通流中的选择性换道行为进行了模型的构建。从微观层次上分析了选择性换道需求产生的机理，提出了一种基于车道行驶满意度的综合评价法。通过对实际车辆单元换道轨迹的观测与换道执行时间的统计分析，建立了车辆换道转角与车速的函数关系。最后利用单个Agent包装类在VC.NET平台上实现了此模型。
