Abstract: Summary In this paper, the traffic flow on weighted scale-free networks is investigated based on local routing strategy using link weights: $P_{l\rightarrow i}=\frac{w_{li}^{\alpha}}{\sum_{j}w_{lj}^{\alpha}}$ . The capacity of links is controlled by max(β w lj ,1). It is shown by simulations that two critical threshold β c1 and β c2 exist. When β>β c1, both the network capacity and the corresponding α c value remain unchanged. When β c1>β>β c2, the network capacity decreases and the critical value of α c increases with the decrease of β. When β
