摘　　要：针对智能网联车队的组队和离队场景从宏观基本图与微观跟驰行为2方面进行建模:首先在宏观层面,研究含有智能网联车队的混合交通流组态概率分布,紧接着对网联车渗透率p以及车队长度S这2个重要参数分别研究其对混合交通流通行能力的影响;其次,从微观角度出发,分别对车队的组队场景和分离场景进行仿真研究其微观运行状况。结果表明:当网联车渗透率为1时,道路通行能力可达到3777辆/h,是不含车队交通流通行能力的1.5倍以上;车辆组成车队所需的时间主要受车间距离以及车队规模影响;车队分离场景的效率以及稳定性均高于组队场景。研究结论可支撑未来车队动态演化过程的研究,同时也可为车队的宏观与微观运行管理提供理论支撑。The article models both macroscopic fundamental diagrams and microscopic following behaviors.Firstly,at the macroscopic level,the probability distribution of the grouping pattern of the mixed traffic flow containing the intelligent connected vehicle platoon is investigated,followed by the two important parameters of connected vehicle penetration p and the length of the platoon S to study their effects on the mobility of the mixed traffic flow,respectively.Secondly,from the microscopic point of view,the formation scenario and separation scenario of the platoon are simulated to study its microscopic operation condition respectively.The results show that:when the penetration rate of networked vehicles is 1,the road capacity can reach 3777 vehicles/hour,which is more than 1.5 times of the traffic flow capacity without a platoon;the time required for vehicles to form a platoon is mainly affected by the distance between workshops as well as the size of the platoon;and the efficiency as well as the stability of the platoon separation scenario is higher than that of the platoon formation scenario.The research conclusions provide a means of platoon management and control,which can support the future research on the dynamic evolution process of the platoon,and also provide theoretical support for the macro and micro operation management of the platoon.
