摘　　要：以元胞自动机184号规则为基础,建立了双向两车道含行人,自行车和汽车的“人车”混合交通流模型.考虑了两车道间的超车影响.通过计算机数值模拟,得到不同的混合比例下的混合交通流基本图及不同的自行车和行人密度下汽车的交通流基本图.通过分析,得出了混合交通流的几个重要特性.Based on the 184th rule of cellular automaton, a traffic flow model of mixing traffic in two-lane system with two opposing directions is proposed, in which the effect of the vehicles＇ overtaking are considered. From the numerical simulations, the fundamental diagrams of mixing traffic flow with different mixing proportion of vehicles and the fundamental traffic flow diagrams of cars under different densities of pedestrain and bicycle are gaind. Some importance characters of mixing traffic flow are obtained through the analysis of the simulations.
