Abstract
This paper presents a formulation and solution procedure for a model which combines residential-location into a combined modal split and assignment model. Main focus is put on how to determine zonal populations endogenously and two models derived from the proposed combined model are presented. The combined land-use and transportation equilibrium model presented here is then applied to Gifu city and its characteristics and validation are examined. The model is enable us to predict the impacts of transportation facilities, the changes in transit fares, etc. on residential location choice, and also the impacts of changes in residential location or employment location associated with supply of housing, new location of firms on the use and performance of transportation systems.
