摘要To improve the ability of city agglomeration to resist emergency disruption, the model of a city agglomeration compound traffic network was constructed with a new perspective on investigating its vulnerability. First, on the basis of complex network theory, the city agglomeration compound traffic network structure was analyzed thoroughly and its model was established using the site mapping method. Then, facing the compound traffic network structure of urban agglomeration, both the different attack strategies and the measures of the vulnerability of a city agglomeration compound traffic network were proposed. Finally, taking Hohhot-Baotou-Erdos city agglomeration as an example of our empirical study, the city agglomeration road network and rail transit network were formed, and the topology characteristics and vulnerability of the compound traffic network were analyzed to identify critical sites and lines within the network. Results show that the construction of urban agglomeration compound traffic network can effectively reduce the vulnerability of a single-mode network. Moreover, strengthening the protection of the identified key sites and lines further increases the likelihood of reducing the vulnerability of urban complex transportation networks and the risks of traffic network paralysis caused by sudden disasters.
