摘要
将GIS技术和虚拟现实技术运用到城市交通仿真系统的微观仿真研究中,在城域景观VRGIS一体化仿真平台基础上建立了城市道路交通微观仿真系统,通过标准化数据模型完成GIS输入交通仿真数据,利用VR技术实现交通仿真的三维可视化,以一种人机交互模式实现虚拟城市环境中的交通微观仿真。该系统用于英国纽卡斯尔市中心重建项目的方案评价中,通过对3种规划方案的优劣对比,为交通管理部门提供一定的决策支持。
Virtual reality and GIS are applied to the microscopic simulation of urban traffic system, and a set of traffic simulation system is developed on the basis of integrated VRGIS navigation platform for city/ region simulation. The paper uses GIS technique input simulation data by dates standardization, realizes the 3D visualization for traffic simulation based on VR, finally realizes a new virtual city traffic simulation system in the man-machine interactive mode. In the scientific research of Newcastle city centre regenera- tion, some schemes have been evaluated. The comparison among the three options will help to choose the preferred one, which can offer some decision-making basis for the traffic management department.
