Research on Supply and Demand Adaptability of Hunan Expressway Logistics Channel Based on Networking Toll Data
Expressway transportation is an important component of modern logistics system.Expressway is the most important carrier in highway transportation.Studying the characteristics of highway freight transportation and analyzing the adaptability between logistics channel supply and logistics demand is conducive to promoting the sustained development of the logistics industry and promoting the deep integration of transportation and modern logistics.Based on the toll collection data of highway networking,the logistics channels of highways can be effectively identified,and the supply and demand adaptability of the logistics channels can be evaluated through traffic saturation indicators.Firstly,the expressway truck online toll collection data is based on the interruption at the path identification point to reduce the computational complexity of the truck running track restoration.Secondly,Breadth-first search algorithm and naive Bayesian classification theory are used to accurately restore the running track of freight cars.Then,based on the operation trajectory of trucks,calculate the freight vehicle flow,freight volume,and saturation on the highway section,and analyze and study the adaptability of transportation facility supply from the perspective of logistics.Taking Hunan Province as the research object,the example shows that the main logistics channels of Hunan Province's expressways are distributed in a pattern of"three vertical and three horizontal".The congestion of G4 Beijing-Hong Kong-Macau Expressway and other sections is increasingly serious,and the connection between G0421 Xuchang-Guangzhou Expressway and Changsha Ring Expressway,Jianggan Expressway and Liuhong Expressway is still not smooth.The research method based on online toll data can efficiently and accurately analyze the supply and demand adaptability of highways strongly related to logistics,providing reference for theoretical research and practical application of logistics channel planning and transportation infrastructure layout.
