湖南省综合交通枢纽城市体系研究

Study on the urban transportation hub city system in Hunan Province

为研究湖南省综合交通枢纽体系,利用高速公路网络数据、铁路车次数据及航空班次数据,对湖南省14个城市对外交通进行了研究,分析了湖南省交通对外联系主要支点城市和宏观布局。再运用城市在公路网、铁路网及航空网中的节点重要度和自身经济情况2类指标,采用系统聚类法,对城市进行了聚类分析,确定了湖南省枢纽城市的层级和个数,以期在多元交通流视角下深化对湖南省交通枢纽城市网络的认知。

In order to study the comprehensive transportation hub system of Hunan Province,the highway network data,the railway traffic data and the aviation flight data are used to study external traffic situation of 14 cities and analyze the main fulcrum cities and macro layout of Hunan transportation in depth.The 14 cities are clustered to determine the level and number of the hub cities in Hunan Province by a system clustering method which uses node importance and economic data.Through the multiple traffic flow perspective,the traffic hub city network in Hunan Province can be cognized.
