The invention relates to the technical field of intelligent network connection and traffic flow cooperative control, and discloses a method, a device, equipment and a medium for measuring and calculating the traffic capacity of a mixed traffic flow. And predicting the congestion condition of the mixed traffic flow to be measured and calculated through a preset Markov chain model. Furthermore, the traffic capacity of the mixed traffic flow to be measured and calculated can be measured and calculated in combination with the predicted congestion state. Therefore, by implementing the method, the foreground theory and the Markov chain model are fully combined, not only is the car-following behavior preference of the HDV driver considered, but also the time distribution characteristics of the traffic congestion state are described, and the credibility and availability of a measurement result are ensured.

    本发明涉及智能网联与交通流协同控制技术领域,公开了一种混合交通流通行能力测算方法、装置、设备及介质,本发明通过前景理论可以刻画跟驰过程中人类驾驶员的驾驶协作意愿关系,同时,通过预设马尔科夫链模型对待测算混合交通流的拥堵情况进行预测。进一步,结合预测的拥堵状态可以实现对待测算混合交通流的通行能力的测算。因此,通过实施本发明,充分结合前景理论和马尔科夫链模型,不仅考虑了HDV驾驶员的跟驰行为偏好,还描述了交通拥堵状态的时间分布特征,确保了测算结果的可信程度和可用性。
