| 摘 要： | 依据江苏省2011年、2014年和2017年高速公路联网收费大数据，选择客车通行数据，通过构建O-D流网络和县域联系网络，揭示了客流空间格局和网络组团结构特征。研究发现，客流的空间分布呈现以市辖区收费站、省界收费站及跨江大桥收费站为高值区域的特征，整体上苏南和苏北差异显著；O-D流网络具有明显的无标度特征，组团结构表现为沿高速公路线路分布的特征；县域联系网络节点的位序-规模呈现首位分布态势，网络可以划分为8个组团，区域中心城市为核心的组团结构特征明显。基于联网收费大数据从流动性视角挖掘公路交通的客流特征与空间结构，可为动态化、精细化和定量化分析交通网络提供新的研究视角和方法工具，为有效揭示公路客流的时空规律、优化公路交通与相关设施空间布局提供科学依据。

| Abstract: | As an important part of modern transportation system, the huge traffic flow of expressway truly reflects the regional connection and has a profound impact on the social economy, people’s life and spatial structure. The massive expressway toll data collection is a significant support to analyse and reveal the traffic flow characteristics and the spatial structure evolution. According to the Jiangsu expressway toll collection data in 2011, 2014 and 2017, this paper selects car traffic to construct the O-D flow network and county connection network, so that the key toll stations and distribution characteristics of network degree are identified effectively, and the spatial pattern of car flow and the features of its network group structure are revealed. It is found that the spatial distribution of car flow shows a notable difference between the south and north of Jiangsu, with high-value points around the toll stations of central cities, provincial boundaries and cross-river bridges. The O-D flow network has an obvious scale-free feature, while the community structure is characterized by distribution along the expressway routes. The county connection network can be divided into 8 communities, with central cities as the cores. |
