摘要：

A road traffic noise prediction model has been developed suitable for use in China. This model is based on local environmental standards, vehicle types and traffic conditions. The model was accurate to 0.8 dBA at locations near the road carriage way and 2.1 dBA within the housing estate, which is comparable to the FHWA model. An integrated noise-GIS system was developed to provide general functions for noise modeling and an additional tool for noise design, where a new interaction mode in "WHAT IF Question/Explanation" format was used. Application of this system offered improvements in the efficiency and accuracy of traffic noise assessment and noise design. (C) 2002 Elsevier Science Ltd. All rights reserved.
