The invention discloses a road impedance prediction method and device for mixed traffic flow, equipment and a medium. The method comprises the following steps: obtaining car-following models of various types of vehicles in a mixed traffic flow, wherein the mixed traffic flow comprises a manual driving vehicle, an automatic driving vehicle and an intelligent network connection vehicle; according to the following models of various types of vehicles and the proportion of each type of vehicles in all vehicles of the mixed traffic flow, establishing a basic diagram model of the mixed traffic flow, the basic diagram model being used for reflecting the road traffic capacity of the mixed traffic flow; substituting the road traffic capacity of the mixed traffic flow and the preset traffic flow of the mixed traffic flow into a pre-acquired road impedance model of homogeneous traffic flow to generate a road impedance model of the mixed traffic flow; the road impedance model of the homogeneous traffic flow is constructed according to the road traffic capacity and the traffic flow of the homogeneous traffic flow; and predicting the road impedance of the mixed traffic flow through the road impedance model of the mixed traffic flow.

    本申请公开了一种混合交通流的道路阻抗预测方法、装置、设备及介质。该方法包括:获取混合交通流中各种类型的车辆的跟驰模型,混合交通流中包括人工驾驶车辆、自动驾驶车辆和智能网联车辆;根据各种类型的车辆的跟驰模型,以及每种类型的车辆在混合交通流的所有车辆中所占的比例,建立混合交通流的基本图模型,所述基本图模型用于反映混合交通流的道路通行能力;将混合交通流的道路通行能力以及混合交通流的预设交通流量代入预先获取的同质交通流的道路阻抗模型中,生成混合交通流的道路阻抗模型;同质交通流的道路阻抗模型根据同质交通流的道路通行能力和交通流量构建得到;通过混合交通流的道路阻抗模型预测混合交通流的道路阻抗。
