基于自动驾驶原理,建立了单车道上由两种长度、可分别以不同的最大速度行驶、具有自动巡航驾驶功能的车辆构成的混合交通流模型.通过计算机数值模拟,得到了混合车流在不同参数下交通流模型的基本图,并借助平均场理论对其进行解析.得到的理论结果与实验模拟相一致.
Based on the principle of automatic driving,the mixed traffic flow model of vehicles with different lengths and maximum velocities on one-lane highway is proposed.We obtained the fundamental diagrams of traffic flow model under different parameters via numerical simulation.Moreover,with the help of mean-field theory,the analytical results are given.The theoretical results are in agreement with those from numerical simulations.
