摘　　要：交通流生成模型是微观交通仿真的最基本模型,主要解决交通流的输入问题。在分析拥挤交通流交通特性的基础上,运用蒙特卡罗(MC)方法模拟拥挤交通流生成,并运用可视化编程语言VB给出算法的程序实现及模块开发,最后结合VISSIM仿真软件进行实时仿真,通过仿真结果与实测数据的对比分析,验证了所设计的拥挤交通流生成模型能够较好地模拟实际拥挤交通流的生成。Traffic flow production model is the basic model in microscopic traffic simulation,which mainly emphasizes on the input of traffic flow.Based on the analysis of the traffic characteristics of congested traffic flow,by using Monte Carlo method,traffic flow production under congested conditions was simulated,the implementation of this algorithm using computer programming language VB was presented and an application module was defined.Finally the simulation result based on VISSIM system and the measured data were compared,which proves that the designed model can simulate the traffic flow production under congested traffic conditions effectively.
