Study On The Statistical Analysis Of Freight Volume Based On Freeway Toll Data

With the maturing of national freeway transport infrastructure and transportation network,carries out the freeway freight volume statistics work,and evaluates objectively about the state of regional freight transport and economic according to the statistical results,and takes appropriate measures to solve the freeway freight transport problems is of great significance to improve the regional comprehensive development level.At present,the research on freeway freight volume statistics is not mature enough,most of the statistical algorithms do not divided meticulously for the type of truck,it is difficult to ensure that the statistical results are accurate and reliable;in addition,the evaluation of the degree of coordination between freeway freight transport and regional economy is still at the level of qualitative analysis,the evaluation results are abstract and cannot intuitively reflect the level of regional development.Paper takes the actual data as a foothold,Firstly analyzes the relationship between the standard gross weight and the unladen weight of freight vehicle,and uses single-peak subset of the separation method to divide the type of truck according to the differences of the number of axles and the standard gross weight,on this basis,establishes the unladen weight parameter table of freight vehicle.Then,the paper puts forward a new method to calculate freeway freight volume on the basis of historical freeway toll data,according to the statistical analysis of the freeway toll data,masters the traffic characteristics,travel frequency and cargo loading characteristics of freight vehicle,establishes a judgment model of full load truck on the basis of the number of travel times and acceptable approved load,based on this model,the type of truck in freeway toll data can be judged,determines the unladen weight of each truck according to the judgment result,thus achieves freeway freight volume statistics.After this,based on the statistical method of freeway freight volume,the paper actually calculates the freight volume of Shaanxi Province,and uses the coupling and coordinating degree model in physics to measure the coordination degree between freeway freight transport and regional economy from two points of view of time and space.Finally,analyzes the inter-provincial and inter-city freeway freight transport problems according to radar chart evaluation method,centrality analysis method and cohesive subgroup analysis method,and puts forward five aspects of suggestions to promote the coordinated development of freeway freight transport and regional economy,namely,consummating the planning work of freeway road network,speeding up the construction of freeway infrastructure,carrying out the informationization construction of freight transport,strengthening the relationship of inter-provincial and inter-city freeway freight transport,promoting the scientific management of freeway freight transport.
