摘　　要：文章考虑交通网络系统的动态性和复杂性,采用Monte-Carlo算法开发了交通流发生程序,结合VIS-SIM仿真软件,实现了不同状态下的交通流实时仿真;分别将稀疏流和拥挤流的仿真结果与实际调查资料进行对比分析,验证了程序的可靠性,为进一步研究多组态交通流仿真技术奠定了基础。Considering the dynamic and complex nature of transport networks, trattic tlow procedures are developed based on the Monte-Carlo method. The real-time simulation of traffic flow under differ ent states is achieved with the help of the VISSIM software. Then the simulation results of both the free flow and the congesting flow are compared with the field data, which proves that the developed program is reliable in simulation of the traffic flow. This study provides a basis for the further research on the multi-configuration traffic flow simulation technology.
