One is recommended by the chinese transportation ministry and is specified in " assessment criteria for environmental impact from road construction projects , jtj005 - 96 " ( to be referred as prediction model from transportation ministry ) . the other is recommended by the national environmental protection bureau and is published in " the general guidelines for environmental assessment technologies ? ound environment , hj / t2 . 4 ? 995 " . this model is the high way noise prediction model from the united states federal high way authority ( fhwa ) 本论文针对当前我国道路交通噪声预测中应用得极为广泛的两种模式：我国交通部在《公路建设项目环境影响评价规范(试行) ( jtj005 ? 96 ) 》推荐的模型(以下简称为交通部预测模型)和国家环境保护总局发布的《环境评价技术导则?声环境[ hj t2 . 4 ? 1995 ] 》推荐的美国联邦公路管理局( fhwa )公路噪声预测模型(以下简称为fhwa预测模型) ，在进行预测时的比较研究。
The basic studying content of this paper is developing and perfecting digital technological management platform in metropolitan roads " traffic noise by geographical information system , that is digital technology . by searching and previewing a lot of documents related with geographical information system , i found there had been few researches in this field 本论文研究的基本内容是在城市道路交通噪声的管理工作中，借助地理信息系统这一数字化的信息技术，对城市道路交通中的噪声管理与分析工作中的数字管理手段的实施的工作技术管理平台进行制作、开发与完善。
By the basis of advanced study on geographical information system and the applying actuality in other fields , we researched on the characteristics , the actuality and the managing methods of metropolitan traffic noise . and we submitted that the mode , which is client / server , should be used in developing metropolitan roads " traffic noise information management system 本论文在深入剖析地理信息系统自身的理论及其在相关专业领域中应用现状的基础上，对城市道路交通噪声的特点、现状及其管理手段进行了研究；提出了在开发基于地理信息系统的城市道路交通噪声信息管理系统时，应采用客户端服务器模式进行开发。
This system has some functions as following : first , statistic analysis and valuation of the spatial distribution of beijing traffic noise ; second , real - time simulation of the affection that is traffic noise in residential area ; third , previewing statues and standards of environmental noise ; fourth , management of spatial data and property data ; fifth , alternant querying of spatial data and property data ; sixth , inputting graphs and tables . we can build accurate and identical channels of information ' s coming , accelerate the circulation rate of environmental information , and increase the efficiency of environmental information resources by studying and implementing metropolitan environmental noise management information system . meanwhile , it can reduce the burden of these environmental workers 城市道路交通噪声信息管理系统的研究与实施可以建立准确、一致的信息来源渠道，加快环境信息的流通速度，提高环境信息资源的利用率，减轻环境工作者的工作负担，提高环境管理工作中的效率，为环境管理和环境规划与评价提供依据；该系统的建立与开发同时也为开发类似系统的环境工作者提供参考和借摘要一鉴，为今后实施集水、气、噪声、固体废弃物为一体的环境管理信息系统平台提供了一个子框架。
