Abstract
Disaggregate model can take into account individual travel behaviors in detail, but in forecasting a case of improving service level of transport networks, the changes in service level of automobile are not often considered. On the other hand, combined stochastic user equilibrium model always considers the changes appropriately. In this study, we apply these two models to the Nagoya metropolitan area in order to verify the difference of prediction results. As compared with the equilibrium model, disaggregate model brings the results that the number of automobile trips is overestimated and one of railway trips is underestimated, although the total number of generated trips and the share of each trip purpose are not so different. Especially, the difference is large in short-distance and middle-distance trips.
