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. So this paper is to some degree innovative and necessary. And because informational management is great prevailing, this paper is to some extent practical.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. On this basis, these four subsystems, included Data Input System, Data Store and Preview System, Data Manipulate and Analysis System and Report System, were designed and built. In these four subsystems, Data Manipulate System and Analysis System is kernel system. Meanwhile, we discussed the developing methods of these four subsystems to some degree.In this paper, according to conditions of Beijing City, we developed Information Management System of Roads’ Traffic Noise of Beijing on the basis of using developing frame of metropolitan roads’ noise management system. In the process of development, we integrate two modes: GIS platform and GIS developing toolkit. The inputting spatial data and building and mending spatial database are on Arc View GIS, one leading software for desktop and mapping. In the Visual Basic 6.0, these functions of querying, analysis, displaying, inputting and store were developed.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 metropolitanenvironmental noise management information system. Meanwhile, it can reduce the burden of these environmental workers. They can use it for environmental planning and environmental estimating. This study also offers a basic frame for implementing general environmental management information system platform, which integrates water, air, noise and garbage.
