摘要
为解决交通组织涉及对象复杂,成果不易表达,改动量较大的问题,狮子洋通道工程中采用结合VISSIM和Unity 3D的BIM技术.基于该技术,以BIM三维模型及车道数据为载体,在VISSIM仿真的基础上,于Unity 3D中与交通量仿真数据集成,实现基于交通仿真分析结果数据驱动的场景展示,准确且直观地表达了不同时期的交通量分析结果,验证了交通仿真分析方法的可行性以及工程适用性,在交通组织方案设计中有着广阔的应用空间.
Abstract
In order to solve the problems that the traffic organization involves complex objects,the results are difficult to express and the changes are large,BIM technology combining VISSIM and Unity 3D is adopted in the Shiziyang Link Project.Based on this technology,the BIM 3D model and lane data are taken as the carrier and integrated with traffic simulation data in Unity 3D on the basis of VISSIM simulation,so as to realize data-driven scene display based on traffic simulation analysis results,accurately and intuitively expresses traffic analysis results in different periods.The feasibility and engineering applicability of traffic simulation analysis method is verified,which has broad application space in traffic organization scheme design.
