Research On Data Acquisition And Analysis Methods Of Rural Highway Technology Status

Rural highway is an crucial part of the road network and one of the most significant infrastructures to guarantee rural social and economic development.The basic requirements are doing a good job in rural road maintenance management and timely grasp the real-time data of highway technology.Therefore,it is extremely important to find a method for data acquisition and analysis of rural highway in Guiyang.Through the combination of the�grid management mode�of Guiyang City's big data,this study puts forward the data acquisition method of grid management mode of the technical status of rural highway in Guiyang,and analyzes the feasibility of applying grid management mode to rural highway in Guiyang.Furthermore,some corresponding analysis methods are proposed as follows:Firstly,coming up with the single evaluation index of the technical status of rural highway asphalt pavement(the crack rate index CRI,the pavement damage condition index DCI and the pavement leveling condition index LCI),the survey index(crack rateC_r,damage rateD_rand planeness index IRI)as well as utilizing the survey data.Then obtaining a single evaluation index model of CRI,DCI and LCI respectively with the help of Data analysis software Origin Pro 9.0.Secondly,the fuzzy comprehensive evaluation method based on fuzzy mathematics is used to evaluate the technical status of rural road asphalt pavement in Guiyang.The method determines the weight of single evaluation index in the comprehensive evaluation system,and establishes the comprehensive evaluation model adapted to asphalt pavement of rural highway.It is beneficial for government departments at all levels to preferably grasp technical status of rural highway in Guiyang.This study mainly aims at the evaluation of the technical status of asphalt pavement.Therefore,it just proposes the preliminary concept and prospects for the road technical status evaluation system instead of providing a complete system.
