The invention provides a quantitative calculation method for the order of a passenger and freight mixed heterogeneous traffic flow in an intelligent network connection environment, and relates to a quantitative calculation method for the order of a traffic flow in a passenger and freight mixed heterogeneous traffic flow scene under the intelligent network connection environment, and the quantitative calculation method for the order of the traffic flow in the passenger and freight mixed heterogeneous traffic flow scene is carried out on an automatic driving vehicle (CAV) and a traditional manual driving vehicle (HV). The intelligent network connection traffic flow has three different vehicle following states of a mixed state, a random state and a separated state, and the road traffic capacity can be obviously influenced by the vehicle following states of different types under the same permeability. According to the method, the order of the passenger and freight mixed heterogeneous traffic flow in the intelligent network connection environment is defined by calculating the occurrence probability of the following state of different vehicles and analyzing the traffic capacity, and the relative entropy is calculated by using the KL divergence, so that the order of the passenger and freight mixed heterogeneous traffic flow in the intelligent network connection environment is quantitatively measured, and the accuracy of the passenger and freight mixed heterogeneous traffic flow in the intelligent network connection environment is improved. And a theoretical basis is provided for intelligent network connection road traffic capacity management and control.

    本发明提供一种智能网联环境下客货混合异质交通流有序性定量计算方法,涉及智能网联环境下自动驾驶车辆(Connected and Automated Vehicles,CAV)与传统人工驾驶车辆(Human‑driving Vehicle,HV)在客货混合异质交通流场景下交通流有序性定量计算方法。智能网联交通流存在混合态、随机态和分离态三种不同车辆跟驰状态,同一渗透率下不同类型车辆跟驰状态会显著影响道路通行能力。本发明通过计算不同车辆跟驰状态出现的概率和通行能力分析,定义智能网联环境下客货混合异质交通流的有序性,并利用KL散度计算相对熵,从而定量衡量智能网联环境下客货混合异质交通流的有序性,为智能网联道路交通通行能力管控提供理论依据。
