虚拟小区交通噪声环境影响预测系统构建研究

CONSTRUCTION OF TRAFFIC NOISE ENVIRONMENTAL IMPACT PREDICTION SYSTEM IN VIRTUAL COMMUNITY

针对建设规划环境影响评价中环境噪声预测结果和控制效果体验直观性差的问题,提出一种虚拟小区交通噪声环境影响预测系统。建立统一数据源以整合交通、建筑、地形、环境等数据,为环境噪声的预测和体验过程提供统一的数据处理平台。基于虚拟现实技术构建小区及其周边交通和声屏障降噪设施的三维虚拟场景,采用噪声地图技术预测虚拟场景中的环境噪声,实现场景漫游和环境噪声体验的同步。通过对某小区的虚拟现实场景搭建和环境噪声体验,验证了该系统的有效性。

Aiming at the problem that the environmental noise prediction results and control effect experience in environmental impact assessment of construction planning are not intuitive,this paper proposes a traffic noise environmental impact prediction system in virtual community.We established a unified data source to integrate traffic,building,terrain,environment and other data,to provide a unified data processing platform for forecasting and experiencing processes of environmental noise.Virtual reality technology was used to construct three-dimensional virtual scene of residential area and its surrounding traffic and noise reduction facilities.And Noise map technology was used to predict environmental noise in the virtual scene,so as to realize the synchronization of scene roaming and environmental noise experience.We verified the effectiveness of the system by building a virtual reality scene and experiencing the environmental noise in a residential area.
