在对现有经典交通流元胞自动机模型进行总体分析的基础上,结合我国城市交通现状,重新标定了元胞长度和最大速度等参数,制定了车道转换规则,提出了公交车辆的减速入站和慢速启动机制,并对各交通参数进行了分析,发现该模型很好的再现了各参数之间的关系. Based on the overall analysis of the existing Cellular Automata model of traffic flow and the current status of urban traffic in our country, the parameters such as cell length and maximum speed are recalibrated. The rules of lane change are formulated and the decelerations of bus Station and slow start mechanism, and the traffic parameters were analyzed and found that the model is a good representation of the relationship between the parameters.
