Abstract
The integrated traffic equilibrium assignment model is proposed in the previous research for impact analysis of toll policy on expressway to local city. In the study, the traffic demand and flow in the urban area of Tokushima and surrounding cities are estimated. Therefore, the demand functions between the objective area and the outside area are estimated considering with base site. The demand functions are integrated to the user equilibrium assignment model with variable demand. And also, the parameters of the transport modal split models for the trip to the outside area are estimated. Finally, the impact to the traffic demand for expressway from the outside area and the traffic flow in the objective area can be estimated with the proposed integrated model as well as the influence to the public transport can be analyzed for some typical toll policies.
