  • In order to estimate traffic volume correctly, the influence factors of generalized cost which influenced the choice of traffic mode and route were analyzed.The components and function forms of generalized cost were studied.Multi-type vehicle conversion model was developed, and its adjustment factors were calibrated.With the theory and method of variational inequality, a network equilibrium model based on generalized cost was established by using the results of network equilibrium model for urban complex traffic.With transportation planning software Emme, an algorithm and program of the model was developed.According to the traffic data from Wenzhou City, some model parameters were calibrated.Analysis result shows that the traffic assignment result of the model is better than that of fractional step loading, especially in the case that the saturation value of road section is higher.
