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。
In order to make Flexsim more suitable for the comprehensive passenger hub simulation, Flexsim is redeveloped using 3DMAX texture mapping and level of detail technology (LOD), and the object-oriented discrete virtual reality simulation technology is used to simulate a city integrated passenger terminal. Visual Virtual Reality 3D Dynamic Demonstration of Integrated Passenger Terminal System Operation. Based on the data statistical analysis function of the Flexsim simulation platform, the passenger flow of the highway passenger terminal is taken as the variable parameter to study its influence on the condition of the waiting room. Simulation results show that when the mean value of Poisson distribution of flow generator parameter is 8, the traffic flow in the waiting room is smooth. When the average value is 5, some passengers can not get on the vehicle in time, waiting in line and eventually causing congestion. Further analysis of the four averages of 8, 7, 6 and 5 shows that in the actual operation, the maximum daily average number of passengers sent by this hub can reach 12 300 passengers per day.
