摘要
从研究微观个体车辆行为出发,考虑两种不同的具有不确定性的加速机制,提出了随机跟弛模型;在随机跟弛模型的基础上,得到了描述交通流宏观行为的连续性动力学方程,该方程是各项异性的,可以避免Daganzo提出的问题.对动力学方程的稳定性分析,得到稳定性判据.
Based on the investigation of the behavior of individual car,a stochastic dynamic model is proposed to describe the macroscopic behavior for traffic flow through consideration of the stochastic acceleration in different case , which have anisotropy by analysis of characteristic velocity . The stable criteria is obtained by analysis for stability of the dynamic equation.
