摘　　要：建立了由两个单车道构成的单个十字路口交通流模型,其中一条东向车道的车子最大速度为2,另一条北向车道的车子最大速度为1。在周期边界条件下,系统中的两条车道按无信号灯管制下并行更新,用元胞自动机确定性FI模型进行了模拟。模拟的结果表明:东向车道上车子的流量分布分为三种情况;和文献[8]相比,流量分布更为复杂;可见,模型中不同的行车规则对十字路口交通流有着重要影响。this paper establishes a crossroad of the traffic flow model by two one-lane roads cross each other,the allowed maximum speed of the car equals to 2 on the east-bound,while it is 1 on the north-bound.Under the period boundary conditions,the parallel update is carried out for the eastbound and northbound roads without traffic lights control,this paper simulates it by the cellular automaton of the definitive FI model.This paper finds that the distribution of flow is divided into three situations according to the results of simulation;Compared with the reference[8],it is more complex.So,the Rule of running automobile effects on traffic flow on the crossroad model.
