Abstract: Based on the theory of complex networks and according to the Gephi software ，an adja?centsitenetwork，aroutenetworkandapublictransitnetworkareestablishedforthebustransporta ?tion systems in Wuhan ，and the topological structures are proposed and several static geometric pa?rameters for these three networks are obtained. Furthermore，topological characteristics which char ?acterizethesethreenetworksareanalysed.Accordingtothedataofthesethreenetworks，itcanfindthat the bus transportation system can meet the current demands. But there are also some problemswhich include uneven distribution，too long waiting time and unable to transfer for some individualsite.Finally ，proposessomesuggestionsonoptimization.
