Within this the train passby noise of the rapid transit system post-completion use is predicted by estimation model. If the difference of the estimated sound level from that of the measurement is large, the desired performance on the prevention facility to be used〈such as sound barrier〉will be greatly reduced. The related software to the noise simulation is widely used to the environmental impact assessment because of the rapid growth of computer and its popularization in recent years. The Peterson’s prediction formula had been used to the assessment on environmental impact until 2003. Is there any excellent advantage in it? How does this model undergoes a long term usage and still not fade? What are the restrictions on its usage? It had not been stated in the environmental impact assessment report involved for the public rapid transit system. This study found that when we input the maximum level of train passby noise, the train speed, the train length, the number of trains and the distance of the receiver from the track centerline in the Peterson’s prediction formula, we can easily obtain the equivalent prediction sound level. The advantages of the Peterson’s prediction formula are that it can be simply used without any special restriction. We can certain the applicability of the Peterson’s prediction formula to Danshui line of the rapid transit system by verifying the difference of the estimation from the measurement. We also can use the SAS software to make the regression analysis. The data is measured from the train noise of the rapid transit system post-completion use. After getting the modified Peterson’s prediction formula, we can apply it to the Danshui line of the rapid transit system around the Danshui area: Leq=(0.97207)*Lmax+(0.96862)*10log(R(1.5D+d)/V)-29.96167 If we round the decimal point of various coefficients in the above equation to integral, the equation as modified is very coincident with the Peterson’s prediction formula. It is shown that the Peterson’s prediction formula is applicable to the Danshui line of the rapid transit system around the Danshui region.謝誌 I 中文摘要 II 英文摘要 III 目錄 Ⅴ 表目錄 Ⅷ 圖目錄 ⅩⅠ 第一章 緒論 1 1.1 研究動機 1 1.2 研究目的 1 1.3 研究範圍與內容 1 1.4 研究方法 2 第二章 捷運交通噪音預測模式文獻回顧 3 2.1 我國大眾捷運交通噪音預測模式之法規發展 3 2.2 我國大眾捷運系統營運交通噪音預測模式分析 3 2.3 捷運交通噪音預測模式 11 2.3.1 經驗模式 11 2.3.2 電腦模式 18 第三章 Peterson噪音預測模式 20 3.1 模式起源 20 3.2 S.
