元胞自动机交通流混合模型的研究

在一维元胞自动机交通流NS模型、FI模型和VDR模型的基础上,考虑不同车辆的驾驶员具有其个性的驾驶方式和习惯,具体表现在不同的驾驶员采用适合于自己行车规则的交通流模型在道路上驾车行驶,从而分别对道路上不同车辆的驾驶员按NS模型和FI模型、NS模型和VDR模型、FI模型和VDR模型的混合驾驶进行了研究和讨论。结果表明,FI-VDR的混合模型更能反映道路畅通、车流增大及描述交通流的复杂非线性现象。

Mixed Cellular Automaton Models of Traffic Flow

Based on the NS model,FI model and VDR model for one-dimensional traffic flow,and with different kinds of rules adopted by drivers,the influences of various mixed rules are found for one system in the traffic.The mixed rules of the NS model and the FI model,the NS model and the VDR model,and the FI model and the VDR model are discussed and analyzed in this article.The FI-VDR mixed model shows that the road is clear and the vehicular flow increases,and describes the complex nonlinear phenomena of the traffic flow as well.
