摘要： 超车是高速公路上非常普遍的现象，传统的模型都不能够很好地刻画超车的一些定性和定量的性质，基于薛国新和顾怀中的超车模型的基础上，在分析超车过程时考虑了车辆超车过程中时一些反应延滞时间、车辆跟弛时的安全距离和超车过程中两车所行驶的路程之间的关系，从而建立了一种新的超车模型。最后，给出一个算例表明此模型能够很好地模拟超车现象，并准确地反映出超车过程中的一些重要的定性性质和定量结果。

Abstract: Overtaking is one of universal phenomena on highway, however, all the traditional overtaking models can not describe its qualitative and quantitative characters very well. Based on the overtaking model proposed by Xue Xinguo and Gu Husizhong, we in this paper present a new overtaking model in which we take into account some reactive delay time during the overtaking process, the safe distance for car-following and the relation between the distances of the two vehicles during the overtaking process. Finally, an example is presented to show that this new model can very well simulate overtaking phenomenon and accurately reflect some important qualitative characters and quantitative results during the overtaking process.

Key words: overtaking, valid running time, safe distance, traffic flow
