The Application of Mathematical and Statistical Method in Road Noise Reduction

Based on the complex nature of traffic noise,this article applies the analytical hierarchy method and weighted system clustering method in the road environmental protection design,which can effectively avoid the lop sidedness caused by subjective factors.Three indicators reflecting the impact of traffic noise are selected and quantified and then the degrees of all affected sensitive points are arranged and grouped.Under conditions of limited time and funds,the optimum design and the effective use of funds can be achieved.
