| As an important carrier of freeway freight transportation in Guizhou province,the measurement and analysis of its freeway freight transportation volume can help reflect the fluctuation of freight transportation volume in the province and optimize the statistical management mechanism of freight transport by trucks registered in the province.At present,the measurement and analysis of provincial truck transportation volume is mainly based on highway traffic data and traffic flow survey data for transportation volume analysis,but there is no integration of data sources such as truck supervision platform data,vehicle network data and highway sampling survey data into the study of full path freight transportation volume,which will be researched in this paper.In this paper,the research is carried out from two aspects: data processing method and transportation volume analysis.Firstly,data processing is carried out on data sources,and the transport volume index of trucks registered in Guizhou province in a single data source is analyzed.Secondly,according to whether the trucks are running on the highway or not,two types of transportation scenarios are built: via the highway and on the general highway,based on which a transportation index fusion system based on multi-source data is constructed to analyze the transportation volume of trucks of Guizhou province in the full path.The main tasks of this paper are as follows:(1)Measurement and analysis of transportation volume of different data sources.Based on three data sources,namely Guizhou highway traffic data,truck supervision platform data and Guizhou highway survey data,this study measures and analyses transport indicators such as cargo type,distance travelled,speed travelled and mass carried of truck transport from two perspectives,including flow direction and vehicle type,laying a data foundation for multisource data fusion.(2)Establish the transportation index system associated with highways and ordinar y highways.In this paper,we apply map matching technology to path matching of ve hicle GPS track data of truck supervision platform,get the full path road information,obtain the truck transportation indexes of truck traveling on ordinary highway via high way and truck traveling on ordinary highway throughout,and reconstruct the complete transportation index system of two types of transportation scenarios.(3)Build a transportation index fusion system based on multi-source data,and propose a research method for freight volume of trucks registered in Guizhou province.The corresponding multi-source data transportation index fusion is carried out in different transportation scenarios.Through the multi-source data fusion,the transportation volume of the whole path of trucks registered in Guizhou province is systematically analyzed,and a comprehensive judgment of the transportation status of Guizhou provincial trucks is made.The research method of freight volume of trucks registered in Guizhou province based on multi-source data fusion proposed in this paper solves the problem of lacking full path cargo transportation volume research method for provincial trucks and provides a new idea for researching highway freight transportation volume. |
