| 摘 要： | 研究基于跟驰模型的交通混沌问题。用Matlab软件编制皮埃莱(Bierley)模型来产生交通流；在一定的参数组合下，仿真研究交通流车队中不同序号的前后车辆之间的车头间距的变化过程；通过分析这种车头间距的变化过程的变化曲线和绘制庞加莱(Poincare)截面图，说明基于跟驰模型产生的交通流存在着混沌现象；讨论模型参数和仿真试验参数对该理论交通流运动的影响，给出相应的仿真研究结果；最后得出对于研究与应用交通流理论有益的结论。

| Abstract: | The chaos of the traffic flow based on the Car following model is studied.The traffic flow is generated based on Bierley Car following model which is programmed by using MATLAB. The changing processes of space headway of the front vehicle and the following vehicle in the traffic flow are obtained by the simulations. The analysis of the changing processes and the Poincare sections of the changing processes shows that chaos of the traffic flow exists indeed. The influence of the model parameters and the simulation parameters on the movement of the traffic flow is discussed and the relevant simulation results are given. Finally,the useful conclusion for study and application of traffic flow theory is presented. |
