【 摘 要 】

In order to improve the accessibility of urban agglomerations traffic network, the accessibility of urban agglomeration compound traffic network was empirically studied from a new view. A quantitative description of the accessibility of urban agglomeration was put forward by weighted travel time, weighted economic potential, and interaction force. Firstly, four single mode of transport sub-networks was built, including highway sub-network, rail sub-network, aviation sub-network and waterway sub-network so that urban agglomeration compound traffic network was formed by the superposition based on complex network theory. Secondly, the effective average travel time, city economic coefficient was chosen as quantitative measure index of accessibility. Finally, the model of Hohhot-Baotou-Ordos urban agglomeration compound traffic network was built to be empirically studied. The results show that it formed a structure of concentric circle with the center of Baotou and the accessibility intensity gradually decreases outward. The effective superposition of highway sub-network and rail sub-network can increase the accessibility of any point.
