摘要
通过重新定义元胞尺寸、状态值及元胞邻域,建立了自行车元胞自动机基本模型,并在基本模型中引入随机偏移概率来表达自行车不遵循车道行驶的特性.通过模型模拟运行,并对获得的自行车流参数进行分析,结果表明引入随机偏移概率能很好地描述自行车不遵循车道随机蛇行、穿插的特性.
Through the re-definition of cellular size,cellular state value and the neighborhood,The paper establishs a bicycle basic cellular automata model and introduc the stochastic offset probability in bicycle＇s base cellular automata model innovatively to express the property of riding not following with one lane.Through models simulation,the paper analyzs the result of the bicycle flow-parameters of simulated models and shows that the stochastic offset probability is corresponding sufficiently to describe the bicycle＇s snaking and interweaving property.
