摘　　要：探索了车联网环境下设置自动驾驶重型卡车(简称智能重卡)专用道的可行性和有效性。以上海市两港大道快速路为研究场景,通过分析实际交通状况,设计正常路段混合交通流下的智能重卡专用道运行规则,构建三车道元胞自动机模型,利用Matlab开发仿真程序,从交通流密度、流量、平均速度等方面对不同网联自动驾驶汽车(CAVs)渗透率条件下的仿真结果进行分析。结果表明,在智能重卡比例0.2、CAVs渗透率0.4~0.7的情形下,设置智能重卡专用道对提升道路通行能力效果显著,且能提高整体交通流的平均速度;尤其当CAVs渗透率达0.6时,效果最佳,道路通行能力提高约23%。The feasibility and effectiveness of setting up a dedicated lane for autonomous heavy trucks(intelligent heavy trucks)in a networked vehicle environment were explored.Taking the expressway of Lianggang Avenue in Shanghai as the research scene,by analyzing the actual traffic conditions,the operation rules of the intelligent heavy truck lane under mixed traffic flow in the normal road section were designed,a three-lane cellular automata model was constructed,and the simulation program was developed by Matlab.The simulation results under different connected autonomous vehicles(CAVs)penetration conditions were analyzed from the aspects of traffic flow density,flow rate,and average speed.The results show that when the ratio of intelligent heavy trucks is 0.2 and CAV permeability is 0.4-0.7,the effect of setting intelligent heavy truck lanes is significant,and the average speed of the overall traffic flow can be improved.Especially when the CAVs penetration rate reaches 0.6,the best effect is achieved,and the installation of intelligent heavy truck lanes can increase the road capacity by about 23%.
