基于复杂网络的西部地区公路网可靠性研究

Reliability Research of Highway Network in Northwest China Based on Complex Network Theory

在复杂网络理论的基础上对西部地区公路网的脆弱性进行了分析,进而得出现有公路网的可靠性。为提升西部地区公路网结构的可靠性,采用原始法构建西部地区公路网的拓扑结构图,运用点度与度分布、平均路径长度、网络效率等统计特性指标,对所构建的拓扑结构进行定量分析;找出可靠性较低的城市进行点度的增加,研究增加后的西部地区公路网数据,并与相对应地区的"十三五"规划进行可靠性对比分析;指出脆弱性较高、节点度较低的格尔木、武威、天水、嘉峪关、白银市应进行多边化规划建设,从而对西部地区新型城镇化的发展起到良好的引导作用。

Based on the complex network theory,the vulnerability of the road network in the western region is analyzed,and the reliability of the existing public network was obtained. The topological structure of the road network in the western region was constructed by using the original method. The topological structure of the road was quantitatively analyzed by using the statistical characteristics such as degree and degree distribution,average path length and network efficiency. The original data of the road network were analyzed to find out the cities with low reliability which were increased by the parameter degree. It was compared with the road network data of the western region and the increase of the degree with the ＂ 13 th Five-Year Plan＂ of the corresponding area. It is pointed out that Golmud,Wuwei,Tianshui,Jiayuguan and Baiyin should be diversified to improve the reliability of the road network structure in the western region. Therefore,it can be a good guiding role in the development of the new urbanization in the western region
