The reconfigure of expressway toll system is discussed from the view of economic effect to the local area recently. It is the purpose of the present study that the impact to the traffic demand and the traffic flow in the local city are estimated quantitatively for the proper evaluation of the toll policy. Therefore, the integrated user equilibrium assignment model is proposed for impact analysis of toll policy on expressway to local city. The demand function between the objective area and the outside area estimated considering with base site. The demand functions are integrated to the user equilibrium assignment model with variable demand. Finally, the traffic demand for the typical toll policies can be estimated and the impact to the traffic flow in the objective area can be analyzed with the proposed model.
