The invention relates to a traffic capacity calculation method for a mixed traffic flow highway confluence area containing a special lane, which comprises the following steps of: firstly, considering the requirements of automatic driving vehicles and the traffic capacity of the automatic driving special lane, and distributing the automatic driving vehicles to obtain the traffic requirements of each lane; secondly, taking the maximum traffic capacity as an optimization target, and proposing a target function; meanwhile, constraint conditions of the traffic flow in the confluence area are given; and finally, establishing a confluence area traffic capacity model according to the target function and the constraint condition, and solving the confluence area traffic capacity model through mathematical programming to obtain the traffic capacity of the confluence area. According to the method, under the mixed traffic flow containing the special lane, the automatic driving vehicle and the manual automatic driving vehicle, the requirements of the automatic driving vehicle and the traffic capacity of the automatic driving special lane are considered; the traffic capacity of the confluence area is quantified through distribution of the automatic driving vehicles and constraint conditions needing to be obeyed by the traffic flow in the confluence area, and the method has guiding significance on management and control of man-machine mixed driving traffic flow containing automatic driving special lanes in the future.

    本发明为含专用车道的混合交通流高速路合流区通行能力计算方法,首先考虑自动驾驶车辆需求和自动驾驶专用车道通行能力,对自动驾驶车辆进行分配,得到各车道的交通需求;其次,以通行能力最大为优化目标,提出目标函数;同时给出了合流区内交通流的约束条件;最后根据目标函数和约束条件建立了合流区通行能力模型,通过数学规划求解合流区通行能力模型,得到合流区通行能力。该方法在含有专用车道以及自动驾驶车辆和人工自动驾驶车辆的混合交通流下,在考虑自动驾驶车辆需求和自动驾驶专用车道通行能力的基础上,通过对自动驾驶车辆进行分配以及合流区内交通流需要遵守的约束条件对合流区通行能力进行量化,对未来含有自动驾驶专用车道下的人机混驾交通流的管控具有指导意义。
