A Review and Update of the Virginia Department of Transportation Cash Flow Forecasting Model

About the report:

This report details the research done to review and update components of the VDOT cash flow forecasting model. Specifically, the study updated the monthly factors submodel used to predict payments on construction contracts. For the other submodel reviewed in this study, the research culminated in the formulation of a new forecasting technique for maintenance expenditures. The report is divided into three sections. The research undertaken to update the "Z-Vectors" of the monthly factors submodel and how these new vectors may be used for forecasting purposes is presented in the fust section. The development of a new model for predicting maintenance expenditures is documented in the second section of the report. How this new forecasting procedure is used is also explained in this section. Finally, recommendations are suggested to improve the Virginia Department of Transportation's cash flow forecasting techniques.
