The Florida Standard Urban Transportation Modeling Structure (FSUTMS) requires socioeconomic data to predict travel demand and transportation needs. Future socioeconomic data are estimated on future land use forecasts, sometimes with the aid of a land use model. These forecasts are made based on array of factors such as changes in population, demographics, structure of local economy, real estate market, land use, growth policies, environmental constraints, and so on. The accuracy of a land use forecast greatly affects that of a demand forecast model. As travel demand models continue to improve, there is a strong desire of planners to improve model input, especially for future forecast years due to the lack of reliable statistics on economy and plenty of uncertainties. |
