The paper improves the velocity ' s control rules of a first - order microcosmic stochastic traffic 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 traffic model 摘要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。
