Abstract: The attack tolerance of Wuhan’s bus network is studied which is attacked by random and intended attack.The network performance is quantitatively measured by the average shortest length，the average clustering coefficient and the size of the largest connected subgraph.It’s found that the empirical network，which is strong to random attack and frail to intended attack by the reason of the inhomogeneous of the degree distribution.

Key words: bus network, random attack, intended attack, attack tolerance
