在交通流NS模型的基础上 ,考虑混合车辆之间存在的速度差异 ,不同车辆的驾驶员在对前车的敏感驾驶随机减速行为过程中其延迟概率是不同的 ,从而提出了一维多速混合车辆敏感驾驶元胞自动机交通流模型 .通过计算机数值模拟得到了混合车辆在不同参数下的基本图 .结果表明 ,与NS模型、SDNS模型相比 ,道路交通流量有较大的提高 ,而且还展现出了亚稳态、相分离等复杂的实际交通行为现象 .结合实际情况 ,对混合交通的特性进行了分析和讨论
Based on the NS model of traffic flow and taking into account the speed difference between hybrid vehicles, the delay probabilities of drivers in different vehicles are different in the process of random deceleration of sensitive vehicles in front of the vehicle, and then the one-dimensional multi-speed Hybrid vehicle sensitivity driving cellular automaton traffic flow model The basic figure of hybrid vehicle under different parameters is obtained by computer numerical simulation.The results show that compared with NS model and SDNS model, the traffic flow of road has a greater increase, and But also shows the complex real traffic behavior such as metastability and phase separation.According to the actual situation, the characteristics of mixed traffic are analyzed and discussed
