为了解、组织及整理整个香港区域的道路交通噪音资料,从而确定、量化及分折交通噪音的严重性,再鉴定相关的噪音缓解措施,香港环境保护署综合了数种先进的技朮,包括地理信息系统、大型的电脑噪音模型、立体影像技朮等,自行开发了一套以立体地理资讯系统为基础的区域噪音模型。从这个系统和模型计算出来的交通噪音地图,加上利用地理信息系统軟件、人口分布的资料库和统计学方法的帮助,评估了整个城市总共有多少居民在那些区域受着多少交通噪音的影响。这些结果可以分析交通噪音的问题,继而决定未来噪音缓解设施及制定综合的计划,以应付这噪音问题。
In order to understand, organize and organize information on road traffic noise throughout the territory of Hong Kong in order to identify, quantify and quantify the severity of traffic noise and to identify relevant noise mitigation measures, the Hong Kong Environmental Protection Department has integrated several advanced technologies including geography Information system, large-scale computer noise model and stereo imaging technology, a set of regional noise model based on three-dimensional geographic information system was developed. Traffic noise maps calculated from this system and model, together with the help of GIS software, population distribution databases and statistical methods, assessed how much of the total number of residents in the entire city were affected by traffic noise in those areas . These results can analyze the problem of traffic noise, and then determine the future noise mitigation facilities and develop a comprehensive plan to cope with this noise problem.
