摘　　要：大型活动的频繁举行,给城市交通组织管理工作带来很大压力。大型活动消散中交通流的时空变化较为复杂,是交通管控工作的重点所在。文中介绍了基于交通流微观仿真软件TSIS的二次开发原理,结合大型活动交通消散过程仿真要求,利用TSIS外部程序接口编写了动态链接库程序,对原TSIS仿真平台进行了功能的拓展,实现了对路网内指定节点进行的外部控制,从而实现了大型活动机动车流交通消散过程的模拟。Frequent large-scale events impose heavy pressure on urban traffic management. The complicated time- space variation in dissipation after the large-scale events is the major concern in traffic control. The secondary development principle based on traffic flow microcosmic simulation software was introduced. With the consideration of traffic dissipation process simulation in large-scale events, a dynamic link library （DLL） software was programmed by using TSIS interface, thus expanding the functions of the original TSIS simulation platform, which realized out- controlling on crossings in network. The simulation of the traffic flow dissipation process after big-scale events was implemented.
