Comprehensive Analysis of the Beijing-Tianjin-Hebei City Cluster Transportation Network

Aimed at optimizing network structure of Beijing-Tianjin-Hebei city cluster,and promoting the development of city cluster traffic integration and economic integration,this paper takes Beijing-Tianjin-Hebei city cluster as study target,the index system of comprehensive evaluation of transportation network is constructed by the traffic-construction,traffic-transport,trafficcrossing and traffic-correlation.what′s more,it uses SPSS model to rate traffic nodes within the city cluster,then applies traffic connection degree model to analyze the transportation network links between cities,so as to build the basic structure of BeijingTianjin-Hebei city cluster′s traffic networks.Studies show that the polarization of urban transport network of comprehensive strength is very serious;traffic network connection is not sound and presents loose structure of the north-south asymmetry;traffic network appears to Beijing and Tianjin as the core radiation out of the three main contact channels,and Beijing as the center of the radial pattern.
