一种基于跟驰理论的城市交通噪声的计算机预估方法

A Computer-aided Pre-evaluating on Urban Traffic Noise based on Car-following Theory

利用车流的跟驰理论,建立了一种用于城市道路交通噪声预估的动态随机模型,反映了城市交通噪声的微观特性,具有随机、动态和实时预估特征。通过预测与实测比较表明建立的交通噪声预估模型具有较高的预测精度,并运用VB6.0编写交通噪声预估软件。

With the Car- following theory, a dynamic and stochastic model for predicting noise on urban traffic is established in this paper. This model, reflecting the tiny view characteristic of noise on urban traffic, is dynamic and stochastic . By comparing the prediction and practical observation traffic noise , this model proves to have higher precision. This thesis also develops the software for the pre - evaluation of urban traffic noise using the Visual Basic 6.0.
