摘  要：根据无信号路口车辆和行人相互影响的特点，定义元胞划分规则、车辆行驶规则、行人演化规则以及行人对车辆的干扰规则，建立基于元胞自动机的无信号路口交通流仿真分析模型。通过对4种典型的城市路段无信号路口的仿真参数设定，分析行人对车辆正常通行的影响。

Abstract： According to the characteristics of the interaction between vehicles and pedestrians at unsignalized intersections， cell division rules， vehicle driving rules， pedestrian evolution rules and pedestrian interference rules are defined. A traffic flow simulation analysis model of unsignalized intersection based on cellular automata is established. By setting the simulation parameters of four typical unsignalized urban road sections， the influence of pedestrians on the normal traffic of vehicles is analyzed.

Keywords： cellular automata; traffic flow; unsignalized intersection
