摘　　要：为探讨自主汽车队列实际行为特性对交通流的影响,针对混入前车跟驰(PF)汽车队列的混合交通流,考虑队列实际行为特性并按照其实际控制策略进行建模,基于元胞自动机方法建立了混合交通流模型。仿真分析表明:队列车头时距、队列渗透率、队列规模、控制增益等队列特征对混合交通流呈现出耦合及非线性的影响特性,不同队列特征下的混合交通流时空特征差异显著;减小队列车头时距或增加队列渗透率对提升道路的通行能力总体是有利的;队列规模及控制增益对交通流量的一致性影响规律不明显,都需要结合其他队列特征进行具体分析。To explore the effect of actual behavior of autonomous vehicular platoon on traffic flow,aiming at the hybrid traffic flow mixed with predecessor following(PF)platoon which is modeled according to the actual control strategy,a hybrid traffic flow model is established based on cellular automata(CA)modeling method.Simulation analysis shows that the effect of platoon characteristics such as time headway,market penetration,platoon size,and control gains on hybrid traffic flow presents coupling and nonlinear properties.The spatiotemporal behavior of hybrid traffic flow with different platoon characteristics is generally much different.Reducing time headway or increasing platoon market penetration is generally beneficial to enhance road capacity.The consistent laws of the effect of platoon size and control gains on traffic flow are not obvious,which must be combined with other platoon characteristics to carry out the analysis.
