Summary: In this research, a statewide forecasting land-use transport model is developed and presented for the state of Tennessee. The land-use model is named the Large-Scale Land Use Model (LS-LUM) and is integrated with Tennessee Statewide Travel Demand Model (TSTM v3). Considering the data collected demographic and socioeconomic data collected at TAZ level and land use condition at the parcel level, the model is developed for the base year 2010 and forecasts the demographic and socio-economic condition of the state of Tennessee from 2015 to 2050 with five years intervals. The developed model is validated using the backcasting approach and the goodness of fit and error measures are provided to show the accuracy of the model. To present the result of the model, an online dashboard is created providing forecasting results from 2020 to 2050 at TAZ and County levels Finally, a software application is developed for running the model with a user-friendly GUI, which enables sharing the model with other parties.
