一维元胞自动机交通流模型随机特性的应用研究

STUDY ON THE STOCHASTICITY OF A FISRT-ORDER TRAFFIC CELLULAR AUTOMATON MODEL

本文对微观一维随机元胞自动机交通流模型的速度控制规则进行了改进,并将其随机特性转化为减速参数合并到宏观一阶连续介质理论交通流模型中,重新构建了反映流量———密度的交通流基本图。在此基础之上,应用微宏观两种模型进行了数值模拟和讨论。

The paper improves the velocity＇ s control rules of a first - order microcosmic stochastic tragic cellular automaton model and incorporates it＇s stochasticity as a deceleration parameter in the construction of the fundamental diagram used by a macroscopic first - order continuum tragic model. Based on simulations, the paper gives a comparison and discussions of both models.
