摘　　要：针对由手动驾驶车辆和ACC(自适应巡航控制)车辆组成的混合车流,考虑驾驶员的个体驾驶特性差异和ACC车辆的运行原理,构建了各自的运行规则,提出了一个新的元胞自动机模型.给出了周期边界条件下的计算机仿真结果,并对其进行了分析和讨论.结论表明:车流中保守型驾驶员的存在导致了道路利用率的降低,而合理的匹配各种车辆的混合比例,能有效提高道路交通的最大流量和临界密度,有效缓解交通拥堵.Aiming at the mixed traffic flow composed of manual driving and adaptive cruise controlling vehicles, a new cellular automaton model is proposed by constructing running rules considering drivers＇ individual features and the principle of ACC. Computers simulation under periodic boundary condition is carried out and analyzed, the results shows that, the existence of conservative drivers in traffic flow reduces the utilization rate of roads,and reasonably adjusting the proportion of various vehicles can increase the max flux and critical density of traffic and alleviate the congestion of traffic.
