Development of the Texas Revenue Estimator and Needs Determination System (T.R.E.N.D.S) Model: FY 2010 Activities

摘要

The T.R.E.N.D.S. model provides transportation planners, policy makers, and the public a tool to forecast revenues and expenses for the Texas Department of Transportation for the period 2010 through 2035 based on a user-defined level of transportation investment. The user, through interactive windows, can control a number of variables related to assumptions regarding statewide transportation needs, population growth rates, fuel efficiency, federal reimbursement rates, inflation rates, taxes, fees, and other elements. The output is a set of tables and graphs showing a forecast of revenues, expenditures, and fund balances for each year of the analysis period based on the user-defined assumptions. During FY 2010, a new module providing local option revenue projections was added. The analysis area for this module is the Metropolitan Planning Organization (MPO).
