基于高速公路收费数据的货物运输量统计分析研究
[Abstract]:With the improvement of the national highway transportation infrastructure and transportation network, the traffic volume statistics of the expressway are carried out, and the regional freight and economic status are evaluated objectively according to the statistical results. At the same time, taking corresponding measures to solve the problems existing in the transportation of the expressway is of great significance to the improvement of the regional comprehensive development level. At present, the research on the statistics of the traffic volume of the expressway is not mature enough, most of the statistical methods do not detail the type of the wagon, so it is difficult to ensure that the statistical results are accurate and reliable; in addition, The evaluation of the degree of highway freight and regional economic coordination is still at the qualitative analysis level, the evaluation result is abstract, and the regional development level can not be directly reflected. In this paper, based on the actual data, the relationship between the standard gross weight and the overall quality of the freight car is analyzed, and a single-modal subset separation method is used to subdivide the truck according to the number of the axle and the total weight of the standard. On this basis, the quality parameter table of the wagon is established. Then, the paper puts forward a method for statistical analysis of the traffic volume of the expressway based on historical charge data, which is based on the statistical analysis of the historical charge data of the expressway, and the traffic characteristics, the travel frequency and the cargo loading characteristics of the cargo vehicle are mastered. And a full-load truck judgment model based on the number of driving times and the acceptable nuclear load is established, the type of the truck in the charging data can be determined based on the model, and the overall preparation quality of each truck is determined according to the judgment result, so that the traffic volume statistics of the goods can be realized. After that, the traffic volume of the goods in Shaanxi province is calculated by the statistical method of the traffic volume of the expressway, and the degree of coordination between the freight and the regional economy of the expressway is measured from the two angles of time and space respectively by using the coupling coordination degree model in physics. In the end, the problems existing in the freight transportation of the inter-city and inter-city are analyzed by the radar image evaluation method, the central analysis method and the condensed subgroup analysis method, and the highway network planning work is well done, and the construction of the expressway infrastructure is accelerated. The five aspects of carrying out the information construction of the freight transport, strengthening the inter-provincial and inter-city freight interaction, and promoting the scientific management of the freight transportation by the government and the enterprise are to promote the development of the transport of the expressway and the regional economic coordination.
