Abstract: To ensure the security operations of urban agglomeration transportation system, the perspective on compound network is used to explore the invulnerability of urban agglomeration traffic network. The site mapping method is used to build the model of weighted compound traffic network in city agglomeration. The traditional invulnerability metrics is revised and the attack strategies are determined according to the structure of the network. Hu-Bao-E city agglomeration is taken as an example to build the weighted compound traffic network model which is composed of road network and rail transit network, simulating the invulnerability and identifying key nodes in the city agglomeration. Results show that the construction of compound traffic network effectively improves the invulnerability of single mode traffic network and the strengthening protection of the key nodes can improve the invulnerability of compound traffic network in city agglomeration.

Key words: city agglomeration, weighted compound traffic network, invulnerability, key nodes
