基于智能手机的路面平整度评价方法研究
Research on Pavement Roughness Evaluation Method Based on Smartphones
摘要
Abstract
To address the low efficiency and high cost of current detection methods,as well as the insufficient accumulation of pavement damage data on rural low-grade roads,this study developed a vehicle vibration data acquisition application based on smartphones and proposed a conversion method for calculating an index equivalent to the international roughness index(IIRI).Vertical acceleration signals collected during vehicle travel were proposed through high-pass filtering and denoising to calculate the vertical displacement,from which a converted II'RI was derived.Experimental results show that although the data collected by smartphones has slightly lower accuracy than that collected by professional detection equipment,the proposed II'RI exhibits a high correlation with the traditional II'RI,effectively reflecting pavement roughness characteristics.This method provides an economical,efficient,and convenient solution for roughness detection on low-grade roads,with significant application value for large-scale pavement condition monitoring and preliminary screening.关键词
