A process and computer model for forecasting transportation program cash flow are described. The differences between financial management on an accrual or encumbrance basis and full cash flow management are briefly discussed. The need for a comprehensive yet compact and flexible process for relating all aspects of an organization's financing is addressed. The financial overview framework used by the florida department of transportation, called the program plan model, is described. The logic used to define categories and subcategoriesfor program planning and cash flow forecasting is explained. The cash flow model is described, and its inputs, outputs, and variables are explained. Variables in the model, which include flow rates or payout rates, participation ratios, and receivables, are described. The process for calibration of the model and its reconciliation to a short-term forecast and actuals from previous years is explained. Model outputs, including menu-driven charts as well as printed tables containing all inputs, variables, and results, are outlined. A summary of selected graphical output is included. Reports for tracking andmonitoring are described, and use of the model for district and resource planning is briefly discussed.
