The Indiana Department of Transportation has an operational statewide travel demand model (ISTDM). INDOT also has used the Land Use Central Indiana (LUCI) model to forecast conversion of land to residential and employment uses in future decades over a 44-county area in central Indiana. This paper describes how the LUCI model was expanded to cover the same geographic area as the ISTDM, how the internal structure of each model was made to be compatible with the other model, and how the outputs from each model were made to be suitable as inputs to the other model. The result is an integrated model system that allows forecasts of land use and travel patterns for a specified horizon year, with intermediate reports for each intervening 5-year period. The word “integrated” means that no intervention by the user is needed while the model run is under way. INTRLUDE allows the user to specify scenarios that will affect land use decisions and changes to the state network that may be proposed at certain years before the horizon year.
