「陸上運輸系統(高架道路橋面下聲音)噪音管制方式及改善措施之研究」研究案
| 中文摘要 | 國內近年來高、快速公路的建設，多數路段採高架工程，加上高架道路下方有平面道路，在高架道路完成後，當下方平面道路所產生之交通噪音遇到高架道路底部橋面板時，造成聲音多次反射，而使音量增加，所產生之反射音影響了兩側之住戶，就是目前陳情人所抱怨反射音之問題。 本案希望透過模擬來瞭解噪音影響程度，而考量之因素包括如高架道路橋下吸音率、高架道路橋下（橋邊）交通量與車速、高架道路寬度、兩側距高架道路不同距離民宅或橋面下行人影響程度，在透過調查、監測、模擬與分析後，再提出我國高架道路橋面下降低噪音之建議及改善措施。除了蒐集研析日本等先進國家有關高架道路橋面下聲音之噪音特性及改善措施與調查與探討我國高架道路橋面下之噪音情形，還包括研析我國高架道路橋面下之噪音情形及改善措施語協調公路管理機關討論高架道路橋面下聲音改善措施等工作目標。 今年度陸上運輸系統(高架道路橋面下聲音)噪音管制方式及改善措施之研究計畫工作成果包括： 一、蒐集研析至少日本等先進國家有關高架道路橋面下之噪音特性及改善措施，包括含量測評估方法、防制措施。 二、調查我國高架道路橋面下之噪音情形，包括蒐集彙整國外有關高架道路橋面下噪音之研究方法，並召開2場次專家諮詢會議及分析我國高架道路橋面下與橋邊隔音牆等噪音可能情形地點至少20處。 三、建立我國高架道路橋面下或橋邊之噪音基本資料及改善措施，包括現場調查6處（包括環境狀況、橋面資料、流量與聲音情形）、模擬並瞭解噪音影響程度。 四、協調公路管理機關討論高架道路橋面下聲音改善措施，以廣徵各界針對我國高架道路橋面下噪音之研究方法、可行防制方式或改善措施之意見，並指派專人1名，執行「噪音管制紀實」編撰之文書處理及相關行政作業 | ||

Research Project on Noise Control Solutions and Improvement Measures for Land Transportation System
| 英文摘要 | In recent years, freeway and expressway construction projects in our country often adopt elevated engineering structures along many sections. With plain roads underneath, after completion of viaducts, the noises derived from traffic on plain roads underneath tend to make multiple reflections when they hit the bottom of the viaduct, making the volume of noises increased. Obviously having affected the living quality of the residents on both sides of the roads, these reflection noises have become the main complained issue in petitions concerning reflection noises. This project aims to identify the impact of reflection noises through simulation. The factors to be considered include the sound absorption rate underneath the viaduct, traffic load and speed underneath (or around both sides of) the viaduct, width of the viaduct, and the different impact on residents or passersby with different distances from the area underneath the viaduct. Through investigation, monitoring, simulation and analysis, this project plans to propose recommendations and improvement measures for reducing the noises underneath the viaducts in our country. Other than collecting and analyzing information on noise properties and improvement measures concerning the noises underneath the viaducts in advanced countries, such as Japan, and investigating and discussing about the noise situations underneath the viaducts in our country, the objectives of this project also include analyzing the noise situations underneath the viaducts in our country, proposing improvement measures, and coordinating with road competent authorities to discuss the proposed improvement measures on noises underneath the viaducts in our country.Results of the Research Project on Noise Control Solutions and Improvement Measures for Land Transportation System (Particularly Noises underneath Viaducts) include: 1. Collected and analyzed information on noise properties and improvement measures (including measuring and assessing methods and preventive measures) concerning the noises underneath the viaducts in advanced countries, such as Japan. 2. Investigated the noise situations underneath the viaducts in our countries (including collected and integrated research methods concerning noises underneath the viaducts adopted in foreign countries), convened 2 Expert Advisory Panel meetings, and analyzed the effect of sound-proof walls at 20 spots that are likely to be affected by noises underneath (or around both sides of) the viaducts in our country. 3. Established basic data on noises underneath (or around both sides of) the viaducts in our country and proposed improvement measures. The activities included field investigation of more than 6 spots (including environmental conditions, viaduct data, traffic flow and noises), noise simulation, and determination of the impact of noises. 4. Coordinated with road competent authorities to discuss the proposed improvement measures on noises underneath the viaducts in order to collect opinions from all circles on research methods, feasible preventive measures and improvement measures for noises underneath the viaducts in our country. We also appointed a specific person to compile the “Noise Control Records” and conduct related administrative works. | ||
