摘　　要：随着电动自行车的快速发展,电动自行车与机动车的混行交通已经极大地渗透到城市交通中,它们在一定程度上改变并影响着我国现阶段的交通状况。为此,在Na Sch模型交通流研究的基础上,制定换道规则,建立了一个包含机动车与电动自行车混行在内的混合交通流模型;通过计算机模拟以及定性分析,得到的研究结果表明电动自行车与机动车的数量比例和换道行为对混合交通流影响较大。With the development of electric bicycle quickly,Mixed traffic,which is mainly composed of motorized vehicle and electric bicycle,play an important role in urban towns. To some certain extent,they have changed and affected the traffic in China. In this paper,based on mixed traffic flow of existing Na Sch research,we have established a multi-speed lane traffic flow model which includes motorized vehicle and electric bicycle,at the same time different types of vehicles take different lane changing rules naturally. Mixed traffic flow characteristics are studied by the means of computer simulation and qualitative analyses,the result show that the quantity ratio of motorized vehicle and electric bicycle and lane-changing behavior play an important role in mixed traffic flow.
