交通三维视景仿真软件设计方法

在当前的交通仿真研究中，虚拟现实技术的应用是热点之一也是难点之一，矛盾主要在于二者都是硬件资源的消耗大户。在目前的主流PC配置下，传统的设计方法无法给虚拟现实技术以充分的发挥空间。为此，文章提出了基于路段交通统计数据的显示模块设计新方案，并在此基础上通过分割地图多PC处理虚拟城市以及独立出显示模块，在自由交通流基础上对仿真结果二次逼近等手段突破了交通仿真研究中虚拟现实技术的应用在计算机硬件能力和网络传输能力上的瓶颈，并完成了基于Paramics—WTK平台的三维视景仿真软件。真正实现了虚拟城市环境下的交通仿真。

Design Method for 3D Vision Traffic Simulation Platform

The application of Virtual Reality technologies in today's traffic simulation researches is one of the hotspots as well as one of the difficulties.The antinomy is they both cost a great deal of hardware resources.Traditional traffic simulation design method can't give VR enough interspaces.So the paper brings forward a new design method of simulation display module which bases on link traffic flow statistics,and then helps to break through the PC hardware limit as well as the net transport speed through splitting virtual city to separated zones and re-approaching simulation result,finally realizes a new virtual city traffic simulation software based on Paramics-WTK developing platform.
