城市噪声管理信息系统中道路交通噪声预测评价的实现

Road Traffic Noise Prediction and Assessment in Urban Noise Management Information System

介绍了城市噪声管理信息系统的目标、结构及其功能 ,详细阐述了采用城市交通干线噪声平均值公式、FHWA模型与GIS集成的方法进行城市道路交通噪声预测评价。该方法可实现城市交通干线噪声平均值及任一噪声预测点噪声值的计算 ,并能以等声级形式表示道路噪声分布情况。其作为城市噪声管理信息系统的一项重要应用功能 ,为道路交通噪声预测评价提供了方便有效的工具。

The object,structure and functions of Urban Noise Management Information System are introduced simply,and the method of road traffic noise prediction and assessment is described by integrating urban traffic main roads noise average ,FHWA model with GIS .With the method,the urban traffic main roads noise average and noise value of any predicted points can be calculated,and the distribution of noise along the road can be shown in the form of noise contours.As an important function of Urban Noise Management Information System,it prorides an effective tool for road traffic noise prediction and assessment.
