Abstract:
The noise mapping system is a best tool for environment noise controlling, as it can provide a graphical illustration of sound exposure levels in a region for the policy- maker. In urban construction planning, land-use definition and noise environment impact assessment, the noise map has been proved very useful for its efficiency. According to the application requirements of traffic noise prediction model, the CATNMP (Computer Aided Traffic Noise Mapping Platform) has been designed and analyzed in details. The key techniques of algorithm and procedures involved are studied and implemented. An open source topological software package of JTS is used for the development of CATNMP based on GIS data. The traffic noise prediction model is performed with the aid of the computer software system, and a noise map is drawn out. In order to improving the computation efficiency, the distributed computing technique has been implemented in the CATNMP. Finally, the road traffic noise levels in a demonstration area of Beijing city are predicted using the CATNMP and a noise map is drawn for illustration and evaluation of environmental noise. The result shows that the CATNMP can provide an efficient analytical tool for the environmental evaluation of traffic noise, and also technical bases for regional noise emission management.
