Abstract :
In this comments paper, we revisit the network model introduced in Cui, Y., et al (2006). We discuss the inaccuracy of the model and, to correct the network model, we propose to apply directed capacity constraints for directed flows. Based on a comparison of numerical results, we show that the corrected model leads to better accuracy than the original model.
