摘　　要：为使Flexsim更适用于综合客运枢纽仿真,应用3DMAX的纹理映射及细节层次技术(LOD)对Flexsim进行二次开发,运用面向对象离散虚拟现实仿真技术,对某城市综合客运枢纽站进行仿真,实现综合客运枢纽系统作业全过程的可视化虚拟现实3D动态演示。借助Flexsim仿真平台的数据统计分析功能,以公路客运枢纽站客流量为变化参量,研究其对于候车室状态的影响。仿真结果表明:当人流发生器参数泊松分布的均值为8时,候车室通行顺畅;均值为5时,有部分旅客不能及时上车,须排队等待,最终造成拥堵。通过对8、7、6、5这4个均值进一步分析表明:在实际运营中,该枢纽站最大日均旅客发送量可达12 300人次/d。To make Flexsim more suitable for comprehensive passenger hub application, the Flexsire simulation platform was developed with 3DMAX texture mapping and Levels of Detail （LOD） technique. Using the obiect-oriented virtual reality simulation technology, a comprehensive passenger hub was simulated to achieve visual virtual reality 3D dynamic presentation of the hub system operation. With the help of Flexsim data statistics function, the changes of waiting room under different passenger flow conditions were analyzed. The simulation result show that when the Poisson average of passenger generator parameter is 8, the waiting room works normally and pas- sengers take buses fluently. When the average is 5, some passengers cannot get on bus in time and they have to wait, it will cause traffic jam. The average 7 and 6 are analyzed continuously to identify the effects of passenger flow changes on waiting room, the result shows that the hub can deliver 12 300 passengers per day in practice. 14 figs, 12 refs.
