【摘要】：隨著城市化進(jìn)程的推進(jìn)和道路交通網(wǎng)的擴張,由城市機動車帶來的道路交通噪聲問題日益凸顯,不僅對道路周邊居民的生活和工作帶來影響,而且對道路交通事業(yè)的蓬勃發(fā)展造成阻礙。因此,科學(xué)、有效地預(yù)測城市道路交通噪聲及其對周邊區(qū)域的影響顯得十分迫切。首先,本文分析了城市道路交通噪聲的評價指標(biāo)及其適用范圍。介紹了道路交通噪聲的特點、危害和影響因素,詳細(xì)闡述了其常用評價指標(biāo)的優(yōu)缺點和適用范圍,最終選取LAeq(等效連續(xù)A聲級)作為本文的評價指標(biāo)。此外,還闡明了評價道路交通噪聲的國家標(biāo)準(zhǔn)。其次,改進(jìn)FHWA(美國聯(lián)邦公路局)模型。闡述應(yīng)用較為廣泛的預(yù)測模型,分析了模型的影響因子及其適用條件。然后結(jié)合我國城市的道路交通特點,選取FHWA模型進(jìn)行噪聲預(yù)測,對比分析預(yù)測結(jié)果,并根據(jù)實際監(jiān)測情況對模型進(jìn)行修正。再次,提出了基于參數(shù)學(xué)習(xí)的道路交通噪聲預(yù)測模型。在上述改進(jìn)模型的基礎(chǔ)上,引入?yún)?shù)學(xué)習(xí)的概念,將機器學(xué)習(xí)方法用于模型的訓(xùn)練,利用機器學(xué)習(xí)的自學(xué)習(xí)性和自組織性進(jìn)行模型參數(shù)的修正。經(jīng)過對實驗結(jié)果的分析,發(fā)現(xiàn)模型具有較高的準(zhǔn)確性和實用性。最后,利用GIS(地理信息系統(tǒng))相關(guān)軟件繪制了南京奧體中心和五臺山體育場周邊道路交通噪聲地圖。研究了GIS及其在道路交通噪聲預(yù)測領(lǐng)域的應(yīng)用,闡述了噪聲地圖的繪制過程。利用上述基于參數(shù)學(xué)習(xí)的預(yù)測模型得到的噪聲數(shù)據(jù),結(jié)合區(qū)域交通地理信息基礎(chǔ)數(shù)據(jù),繪制出了目標(biāo)區(qū)域的道路交通噪聲地圖,直觀地展示了城市道路周邊的交通噪聲分布情況。
[Abstract]:With the development of urbanization and the expansion of road traffic network, road traffic noise caused by urban motor vehicles is becoming increasingly prominent, which not only has an impact on the life and work of the residents around the road. And to the vigorous development of road traffic cause obstacle. Therefore, it is urgent to effectively predict the traffic noise and its influence on the surrounding areas. First of all, this paper analyzes the evaluation index of urban road traffic noise and its scope of application. This paper introduces the characteristics, harms and influencing factors of road traffic noise, expounds in detail the advantages, disadvantages and applicable scope of its commonly used evaluation indexes, and finally selects LAeq (equivalent continuous A sound level) as the evaluation index of this paper. In addition, the national standards for evaluating road traffic noise are expounded. Secondly, improve the FHWAs model. This paper expounds the widely used prediction model, and analyzes the influence factors and applicable conditions of the model. Then according to the characteristics of urban road traffic in China, the FHWA model is selected to predict the noise, and the prediction results are compared and analyzed, and the model is modified according to the actual monitoring situation. Thirdly, a traffic noise prediction model based on parameter learning is proposed. On the basis of the above improved model, the concept of parameter learning is introduced, and the machine learning method is applied to the training of the model, and the self-learning habits and self-organization of machine learning are used to modify the parameters of the model. Through the analysis of the experimental results, it is found that the model has high accuracy and practicability. Finally, the road traffic noise map around Nanjing Olympic Sports Center and Wutai Mountain Stadium is drawn by using GIS (Geographic Information system) software. In this paper, GIS and its application in road traffic noise prediction are studied, and the process of noise map drawing is expounded. The road traffic noise map of the target area is drawn by using the noise data obtained from the above prediction model based on parameter learning and combining with the basic data of regional traffic geography information. The distribution of traffic noise around urban roads is displayed intuitively.
