摘　　要：为针对突发事件对交通流进行研究,基于ABM技术建立了车辆Agent的适应性决策模型,给出车辆Agent的行驶模型,引入跟驰行为中加速度的算法,利用开源平台Swarm,对实验案例进行分析,得出在工农路与桃园路和啬园路与园林与交叉路口的车流速度、排队长度和车辆Agent数量之间的关系,为建立有效的应急交通预案提供可靠的数据依据.The study on the traffic has been carried on aiming at the emergency events. The decision model of the adaptive vehicle was built based on the ABM technology. Acceleration algorithm of the following behavior was introduced with the driving model of the vehicle Agent. The vehicle queue length and the quantity relation between the vehicle Agents were obtained by analyzing the cases experimentally on the open source platform Swarm, which provided reliable data basis for establishing the effective emergency traffic preparedness.
