The main purpose of this project is to review and make necessary addition or revision to the content of the Technical Specifications for Noise and Vibration Assessment Models. This project plans to probe into the existing technical specifications for various assessment models in terms of prediction and assessment models, noise and vibration sources, applicable objects, restrain conditions, and model parameters, so as to propose a series of more reasonable and applicable technical specifications for assessment models. Based on the results of the implementation of this project, it is hoped that analytic data relating to various existing noise and vibration models home and abroad will be collected and a User’s Guide be formulated in accordance with these analytic data in order to enhance the convenience and correctness of the environmental impact assessment process performed by related professionals and improve the quality of the Environmental Impact Assessment Report, so as to enhance the efficiency and impartiality of the review process conducted by environmental protection authorities. The tasks planned for this Project include the addition or revision to the content of the existing assessment models for the road traffic noise, construction noise, railway traffic noise and environmental vibration and study on the addition of assessment models for the industrial noise. The results obtained include: 1) having collected data on various noise and vibration prediction models home and abroad; 2) having conducted calibration and validation to both existing and additional models; 3) having reviewed the appropriateness of various noise and vibration assessment models. In terms of the technical specifications for road traffic noise assessment models, SoundPLAN, CadnaA, Zhang Fu-nan model and Shi Hong-zhi model have been revised, other models only slightly modified in wording, and Guo Hong-liang model added. In terms of the technical specifications for construction noise assessment models, SoundPLAN and Huang Rong-cun model have been revised, other models only slightly modified in wording, and source type of dump truck moving in working added to the technical specifications for Guo Hong-liang model, Zhang Fu-nan model and Shi Hong-zhi model. In terms of the technical specifications for railway traffic noise assessment models, there have been no models added except for some modification in wording. The technical specifications for industrial noise assessment models form a newly added part. In terms of the technical specifications for environmental vibration assessment models, User’s Guide of the Prediction Model for Ground Propagating Vibration of the Rail System (prepared by the US Department of Transportation) and the vibration level of construction machinery have been added and other models only slightly modified in wording.
