Abstract：To improve the robustness of urban public transport system, an edge adding strategy based on transfer is formulated. Take the bus-subway composite network in Jinan as an example, the characteristic parameters and robustness of the network are studied, and an edge adding strategy based on transfer is proposed to improve the network robustness. The research shows that the composite network has the characteristics of small world and scale-free network; The network is more vulnerable than random attack under intentional attack; The network robustness is improved significantly by the high-degree edge addition strategy under betweenness attacks, which increases the proportion of attacked stations by 50.46% when the network is paralyzed; The network robustness is improved significantly by the high-betweenness edge addition strategy under random attacks and degree attacks, which increases the proportion of attacked stations by 23.35% and 39.81% respectively.
