中文摘要：

基于Bierley跟驰模型理论，建立了由5辆机动车组成的动态交通流仿真模型。利用Matlab软件产生了5辆机动车的交通流时间序列，分析了相邻前后车辆的车头间距、速度差等变化过程，对仿真结果与实际交通流特点做了理论分析。讨论了模型参数对交通流动力学特性的影响，并从理论上证明了短时交通流具有混沌特性。结果表明：后车驾驶员对前后车相对速度和前后车车头间距越敏感就越容易出现混沌现象。

英文摘要：

Based on Bierley car-following theory, a dynamic traffic flow simulation model of five vehicles was established. Utilizing the Matlab software, the traffic flow time series of five vehicles was generated. Variation process headway and speed difference between the front vehicle and the following vehicle were analyzed. The simulation results were analyzed in theoretically with real traffic flow. The influence of the model parameters on the dynamic characteristics of simulation traffic flow was discussed and the chaotic characteristics of short-term traffic flow were proved theoretically. Results show that the more sensitive the following vehicle driver is to relative velocity and headway between the front vehicle and the following vehicle, the more easily chaos is generated.
