Based on Flexsim simulation platform, a 3D virtual reality simulation model of a large container terminal yard in China is created to assist its road planning. Combining the model with the road capacity theory, the appropriate width of the road in the yard is determined. The architecture, components and processes of the model are discussed. Through simulation experiments, the peak traffic flow data are obtained.Comparing the data with the road traffic capacity, it can judge the reasonableness of the road planning and make recommendations for improvement.%利用Flexsim仿真软件建立规划中的中国某大型集装箱码头堆场3D虚拟现实仿真模型,结合道路通行能力理论,辅助该码头堆场的道路规划,确定合理的上千道路宽度.给出模型的体系结构、组成和流程.通过仿真实验,获取高峰期主干道路交通流量数据,与道路通行能力进行比对,判断道路设计的合理性并提出改进建议.
