摘　　要：公路运输是现代物流体系中的重要组成部分,高速公路是公路运输中最重要的载体,研究高速公路货运特征,分析物流通道供给和物流需求之间的适应性,有利于推进物流行业持续向好发展,推动交通运输与现代物流深度融合。基于高速公路联网收费数据,可有效识别高速公路物流通道,并通过流量饱和度指标来评估物流通道的供需适应性。首先将高速公路货车联网收费数据基于路径识别点处打断,降低货车运行轨迹还原的计算复杂度;其次利用广度优先搜索算法、朴素贝叶斯分类理论精准还原货车运行轨迹,然后根据货车运行轨迹,计算高速公路路段货运车流量、货运量、饱和度,从物流的角度分析研究交通设施供给的适应性。以湖南省为研究对象的实例表明,湖南省高速公路物流主通道成“三纵三横”的格局分布,京港澳高速公路等路段拥堵日益严重,许广高速公路与长沙绕城高速、江干高速与浏洪高速等衔接仍有不畅。基于联网收费数据的研究方法,可以高效精准地分析与物流强相关的高速公路供需适应性情况,为物流通道规划及交通基础设施布局的理论研究和实践应用提供参考借鉴。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-Macao 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.
